approaches are ma king rational design of materials more feasible and powerful than ever. M aterials Genome\, machine learning and AI-assisted designs\, are signific antly expediting the materials design process and bringing many hidden op tions to the table. Meanwhile\, the development of state-of-the-art chara cterization techniques is allowing people to have more insightful look at the crystal structure and microstructure of materials\, which leads to d eeper understanding of the structure-property relationship of materials a nd more effective materials design guidelines. \nChen group at Georgia Te ch works at the nexus of computation\, material design\, synthesis and ad vanced characterizations. We have developed a number of in situ character ization platforms for different synthesis methods (e.g.\, solid state\, h ydrothermal\, molten salt and electrochemical syntheses) and a variety of operando characterizations for batteries and other electrochemical devic es. With using lab or synchrotron X-ray sources\, in situ/operando XRD\, PDF\, XAS can be performed to provide unprecedented information on the ph ase/structure evolution of materials in their syntheses and their functio ning processes in devices. We also closely collaborate with computational material scientists to develop novel materials\, leveraging the power of high-throughput first principles computations. Some of our recent resear ch projects will be presented. (1) Understanding the nucleation and polym orph selectivity of metal and alloy nanoparticles in solution with using in situ XRD. (2) Design of phase-transition-free long-cycling cathode for high energy Na-ion batteries. (3) Design of high-performance solid elect rolytes for all-solid-state Li-ion batteries. Other ongoing research topi cs such as recycling of spent batteries will also be briefly mentioned. \ n\nHosted by Olivier Delaire DURATION:PT1H DTSTAMP:20220909T182525Z DTSTART;TZID=America/New_York:20221005T120000 LAST-MODIFIED:20220909T182525Z LOCATION;X-BEDEWORK-UID=18832edc-1b27e154-011b-28298380-0000003c:Hudson Ha ll 125 STATUS:CONFIRMED SUMMARY:MEMS SEMINAR:Design Better Batteries--Rational Materials Design Ex pedited by Computation and Advanced In Situ/Operando Characterizations UID:CAL-8a018f14-821da122-0182-894c7430-000019d2demobedework@mysite.edu X-BEDEWORK-ALIAS;X-BEDEWORK-PARAM-DISPLAYNAME=Main:/user/public-user/Utili ties/Main X-BEDEWORK-ALIAS;X-BEDEWORK-PARAM-DISPLAYNAME=Panel_Seminar_Colloquium:/us er/public-user/Lectures_Conferences/Panel_Seminar_Colloquium X-BEDEWORK-ALIAS;X-BEDEWORK-PARAM-DISPLAYNAME=Training:/user/public-user/O ther/Training X-BEDEWORK-ALIAS;X-BEDEWORK-PARAM-DISPLAYNAME=Engineering:/user/public-use r/Topics/Engineering X-BEDEWORK-CS;X-BEDEWORK-PARAM-DESCRIPTION="/principals/users/agrp_PrattSc hool,":Pratt School of Engineering X-BEDEWORK-ALIAS;X-BEDEWORK-PARAM-DISPLAYNAME="Teaching & Clas sroom Learning":/user/public-user/Topics/Teaching Classroom Learning X-BEDEWORK-SPEAKER:Hailong Chen ( Georgia Tech) X-BEDEWORK-SUBMITTEDBY:sg309 for Mechanical Engineering and Materials Scie nce (MEMS) (agrp_PrattSchool_MEMS) END:VEVENT BEGIN:VEVENT CATEGORIES:Teaching & Classroom Learning CATEGORIES:Engineering CATEGORIES:Lectures/Conferences CATEGORIES:Other CATEGORIES:Utilities CATEGORIES:Panel/Seminar/Colloquium CATEGORIES:Training CATEGORIES:Main CONTACT;X-BEDEWORK-UID=8a009144-7fb64372-0180-046446c3-00004088:Gray\, Sha until CREATED:20220810T194847Z DESCRIPTION:My research vision is that future humans will be more like rob ots (i.e.\, digital\, computational\, cyber\, augmented\, etc.) whereas r obots will be more like humans (i.e.\, soft\, distributed sensation\, con tinuous actuation\, artificial intelligence\, etc.). This talk will intro duce my research on the mechanics\, materials\, bio-integration and funct ionalities of soft electronics based on inorganic electronic materials su ch as metals\, silicon\, carbon nanotubes (CNT)\, and graphene. In partic ular\, epidermal electronics\, a.k.a. e-tattoos\, represent a class of st retchable circuits\, sensors\, and stimulators that are ultrathin\, ultra soft\, and skin-conformable. My group has invented a dry and freeform "cu t-and-paste" method for the rapid prototyping of multimodal\, wireless\, or very large area e-tattoos that offer high-fidelity biometric sensing a nd long-term wearability. While e-tattoos are for human wear\, e-skins ar e to be put on robots for them to imitate human sensations. Despite decad es of research\, soft capacitive pressure sensors still suffer from two b ottlenecks - declined sensitivity with increasing pressure and coupled pr essure-stretch responses. We therefore engineered a stretchable and ultra sensitive e-skin based on hybrid piezoresistive and piezocapacitive respo nses. It has enabled an inflatable smart finger with tunable shape and st iffness that is suitable for a variety of tasks.\n\nHosted by Xiaoyue Ni DURATION:PT1H DTSTAMP:20220914T184826Z DTSTART;TZID=America/New_York:20221012T120000 LAST-MODIFIED:20220914T184826Z LOCATION;X-BEDEWORK-UID=18832edc-1b27e154-011b-28298380-0000003c:Hudson Ha ll 125 STATUS:CONFIRMED SUMMARY:MEMS SEMINAR: “E-Tattoos vs. E-Skins” UID:CAL-8a018f14-821da122-0182-894d66d4-000019d3demobedework@mysite.edu X-BEDEWORK-ALIAS;X-BEDEWORK-PARAM-DISPLAYNAME=Main:/user/public-user/Utili ties/Main X-BEDEWORK-ALIAS;X-BEDEWORK-PARAM-DISPLAYNAME=Panel_Seminar_Colloquium:/us er/public-user/Lectures_Conferences/Panel_Seminar_Colloquium X-BEDEWORK-ALIAS;X-BEDEWORK-PARAM-DISPLAYNAME=Training:/user/public-user/O ther/Training X-BEDEWORK-ALIAS;X-BEDEWORK-PARAM-DISPLAYNAME=Engineering:/user/public-use r/Topics/Engineering X-BEDEWORK-CS;X-BEDEWORK-PARAM-DESCRIPTION="/principals/users/agrp_PrattSc hool,":Pratt School of Engineering X-BEDEWORK-ALIAS;X-BEDEWORK-PARAM-DISPLAYNAME="Teaching & Clas sroom Learning":/user/public-user/Topics/Teaching Classroom Learning X-BEDEWORK-SPEAKER:Nanshu Lu ( UT Austin) X-BEDEWORK-SUBMITTEDBY:sg309 for Mechanical Engineering and Materials Scie nce (MEMS) (agrp_PrattSchool_MEMS) END:VEVENT BEGIN:VEVENT CATEGORIES:Teaching & Classroom Learning CATEGORIES:Engineering CATEGORIES:Lectures/Conferences CATEGORIES:Other CATEGORIES:Utilities CATEGORIES:Panel/Seminar/Colloquium CATEGORIES:Training CATEGORIES:Main CONTACT;X-BEDEWORK-UID=8a009144-7fb64372-0180-046446c3-00004088:Gray\, Sha until CREATED:20220810T194950Z DESCRIPTION:The human hand is the pinnacle of dexterity - it has the abili ty to powerfully grasp a wide range of object sizes and shapes as well as delicately manipulate objects held within the fingertips. Current roboti c and prosthetic systems\, however\, have only a fraction of that manual dexterity. My group attempts to address this gap in three main ways: exam ining the mechanics and design of effective hands\, studying biological h and function as inspiration and performance benchmarking\, and developing novel control approaches that accommodate task uncertainty. In terms of hand design\, we strongly prioritize passive mechanics\, including incorp orating adaptive underactuated transmissions and carefully tuned complian ce\, and seek to maximize open-loop performance while minimizing complexi ty. To motivate and benchmark our efforts\, we are examining human hand u sage during daily activities as well as quantifying functional aspects su ch as precision manipulation workspaces. \n\nHosted by Boyuan Chen DURATION:PT1H DTSTAMP:20220929T204616Z DTSTART;TZID=America/New_York:20221019T120000 LAST-MODIFIED:20220929T204616Z LOCATION;X-BEDEWORK-UID=18832edc-1b27e154-011b-28298380-0000003c:Hudson Ha ll 125 STATUS:CONFIRMED SUMMARY:MEMS SEMINAR:“Mechanical Intelligence” in Robotic Manipulation: To wards Human-level Dexterity in Robotic and Prosthetic Hands UID:CAL-8a018f14-821da122-0182-894e5e27-000019d4demobedework@mysite.edu X-BEDEWORK-ALIAS;X-BEDEWORK-PARAM-DISPLAYNAME=Main:/user/public-user/Utili ties/Main X-BEDEWORK-ALIAS;X-BEDEWORK-PARAM-DISPLAYNAME=Panel_Seminar_Colloquium:/us er/public-user/Lectures_Conferences/Panel_Seminar_Colloquium X-BEDEWORK-ALIAS;X-BEDEWORK-PARAM-DISPLAYNAME=Training:/user/public-user/O ther/Training X-BEDEWORK-ALIAS;X-BEDEWORK-PARAM-DISPLAYNAME=Engineering:/user/public-use r/Topics/Engineering X-BEDEWORK-ALIAS;X-BEDEWORK-PARAM-DISPLAYNAME="Teaching & Clas sroom Learning":/user/public-user/Topics/Teaching Classroom Learning X-BEDEWORK-SPEAKER:Aaron Dollar (Yale University) X-BEDEWORK-SUBMITTEDBY:sg309 for Mechanical Engineering and Materials Scie nce (MEMS) (agrp_PrattSchool_MEMS) X-BEDEWORK-CS;X-BEDEWORK-PARAM-DESCRIPTION="/principals/users/agrp_PrattSc hool,":Pratt School of Engineering END:VEVENT BEGIN:VEVENT CATEGORIES:Visual and Creative Arts CATEGORIES:Diversity/Inclusion CATEGORIES:Engineering CATEGORIES:Arts CATEGORIES:Other CATEGORIES:Utilities CATEGORIES:Reading CATEGORIES:Meeting CATEGORIES:Book Signing CATEGORIES:Main CONTACT;X-BEDEWORK-UID=00f1fcdb-0f068baf-010f-068baf83-00000004:None X-BEDEWORK-COST:Free CREATED:20221025T200451Z DESCRIPTION:Everyone is welcome -- October 2022 is a very special month be cause we are reading Prof. Adrian Bejan's newest book and he will be at o ur gathering!!!

The research field s tarted that way\, and so did my own activity in it. Along the way\, I was drawn to the part of nature (the physics) that was missing from the amor phous view: the structure\, flow\, configuration\, drawing (design)\, pur pose\, and evolution. The lecture is pictorial. It begins with defining t he terms\, because words have meaning: vascular\, design\, evolution\, an d prediction (theory). Next\, the lecture shows that vascular (tree shape d) architectures flow more easily than parallel channels with only one le ngth scale (the wall to wall spacing). Transport across channels is facil itated when the spacing is such that the channel flow length matches the entrance (developing) length of the flow. The tendency to evolve with fre edom toward flow configurations that provide greater access is universal in nature\, bio\, and non-bio. This tendency is the Constructal Law\, whi ch empowers us to predict the evolution toward flow access\, miniaturizat ion\, high density of heat transfer\, and the scaling up (or down) of an existing design.\nMultiscale vasculatures occur naturally because they fl ow more easily than their counterparts with a few length scales. The futu re of evolutionary design everywhere points toward vascular\, hierarchica l flow architectures that will continue to morph with freedom and directi onality.\n\nHost: Xiaoyue Ni DURATION:PT1H DTSTAMP:20220930T131343Z DTSTART;TZID=America/New_York:20221102T120000 LAST-MODIFIED:20220930T131343Z LOCATION;X-BEDEWORK-UID=18832edc-1b27e154-011b-28298380-0000003c:Hudson Ha ll 125 STATUS:CONFIRMED SUMMARY:MEMS SEMINAR: "Vascular materials: Predicting Design Evolution” UID:CAL-8a0183a7-83184018-0183-8e880990-00007c74demobedework@mysite.edu X-BEDEWORK-ALIAS;X-BEDEWORK-PARAM-DISPLAYNAME=Main:/user/public-user/Utili ties/Main X-BEDEWORK-ALIAS;X-BEDEWORK-PARAM-DISPLAYNAME=Lecture_Talk:/user/public-us er/Lectures_Conferences/Lecture_Talk X-BEDEWORK-ALIAS;X-BEDEWORK-PARAM-DISPLAYNAME=Panel_Seminar_Colloquium:/us er/public-user/Lectures_Conferences/Panel_Seminar_Colloquium X-BEDEWORK-ALIAS;X-BEDEWORK-PARAM-DISPLAYNAME=Training:/user/public-user/O ther/Training X-BEDEWORK-ALIAS;X-BEDEWORK-PARAM-DISPLAYNAME=Engineering:/user/public-use r/Topics/Engineering X-BEDEWORK-CS;X-BEDEWORK-PARAM-DESCRIPTION="/principals/users/agrp_PrattSc hool,":Pratt School of Engineering X-BEDEWORK-SPEAKER:Prof. Adrian Bejan X-BEDEWORK-SUBMITTEDBY:sg309 for Mechanical Engineering and Materials Scie nce (MEMS) (agrp_PrattSchool_MEMS) END:VEVENT BEGIN:VEVENT CATEGORIES:Teaching & Classroom Learning CATEGORIES:Engineering CATEGORIES:Lectures/Conferences CATEGORIES:Other CATEGORIES:Utilities CATEGORIES:Panel/Seminar/Colloquium CATEGORIES:Training CATEGORIES:Main CONTACT;X-BEDEWORK-UID=8a009144-7fb64372-0180-046446c3-00004088:Gray\, Sha until CREATED:20220810T195047Z DESCRIPTION:Shock wave / boundary layer interactions are an important feat ure of high-speed flow that occur in supersonic and hypersonic aircraft i nlets\, aircraft control surfaces\, missile base flows\, nozzles\, and ro tating machinery. These interactions are often associated with severe bou ndary layer separation\, which is highly unsteady\, and exhibits high flu ctuating pressure and heat loads. The unsteady motions are characterized by a wide range of frequencies\, including low-frequency motions that are about two orders of magnitude lower than the integral-scale fluctuations in the upstream boundary layer. The low-frequency motions are particular ly problematic for aircraft structures as they can excite the high-amplit ude vibration of thin panels\, which can lead to fatigue and failure. In this seminar\, we will discuss experimental research on various types of shock wave/boundary layer interactions that we have conducted over the pa st 20 years. The discussion will focus on the use of high-speed PIV and p ressure sensitive paint to investigate the physical mechanisms that drive the separated flow unsteadiness in 2D and 3D interactions. \n\nDr. Noel Clemens holds the Clare Cockrell Williams Centennial Chair in Engineering in the Department of Aerospace Engineering and Engineering Mechanics at The University of Texas at Austin.

On the one hand\, fluid-driven actuators capable\ no.f complex motion can power highly adaptive and inherently safe soft ro bots. On the other hand\,\ninflation can be used to transform seemingly f lat shapes into shelters\, field hospitals\, and space\nmodules. In both cases\, just like the simple balloon\, only one input is required to achi eve the\ndesired deformation. This simplicity\, however\, brings strict l imitations: soft actuators are often\nr.estricted to unimodal and slow de formation and deployable structures need a continuous supply\nof pressure to remain upright. Here\, we embrace multistability as a paradigm to imp rove the\nfunctionality of inflatable systems. In the first part of this seminar\, I exploit snapping instabilities\ni.n spherical shells to decou ple the input signal from the output deformation in soft actuators-a\nfun ctionality that can be utilized to design a soft machine capable of jumpi ng. In the second part\nof the seminar\, I draw inspiration from origami to design multistable and inflatable structures at\nthe meter scale. Beca use these deployable systems are multistable\, pressure can be disconnect ed\nwhen they are fully expanded\, making them ideal candidates for appli cations such as emergency\nsheltering and deep space exploration.

Compared to the tr aditional power system configuration\, future power systems will integrat e more renewable resources\, manageable loads\, energy storage systems\, electric vehicles\, and other energy efficient technologies. These new te chnologies will also bring more uncertainty and vulnerability to the powe r systems. Delivering reliable\, resilient\, clean\, and affordable power and energy with large penetrations of renewable energy remains to be a c hallenging problem. Artificial intelligence (AI) has been applied to tack le these challenges by promoting power system decision intelligence. This talk will mainly cover the research of applying artificial intelligence to the sensing of the next generation energy systems: Meteorology-informe d AI for Solar Sensing. We will demonstrate how to use deep learning\, co mputer vision\, and sky camera to enhance solar visibility and predictabi lity. This talk will also briefly introduce other research in learning-en abled energy system modeling and optimization.

Examples can be found in many industries\, including food\, cosme tics and pharmaceutical\, but most importantly they are critical for the production and transport of energy materials. Examples include suspension s of energy carriers\, printable slurries for coatings and batteries\, an d slurries for mining of minerals and metals. Many natural materials invo lved in environmental events also belong to the category of structured fl uids: soil\, mud and snow are just a few examples. Structured fluids ofte n display a complex mechanical behavior that is characterized by features common to both fluids and solids\, with material properties that can cha nge over time due to thermodynamic\, chemical or kinematic conditions. Ou r limited understanding of the behavior of structured fluids can lead to critical industrial challenges and prove environmentally disastrous\, as in the case of clogged subsea pipelines or in landslides and avalanches. Such problems call for immediate solutions to measure and model the mecha nical behavior of structured fluids\, towards an improved understanding o f this vast class of materials and corresponding processes and products.\ n\nMy research demonstrates that these challenges can be overcome by: (i) introducing novel experimental tools and protocols that allow us to stud y the mechanical and rheological response of structured fluids even when their behavior is rapidly changing\, or mutating\, in time\; and (ii) rig orously setting theoretical frameworks that explain the experimental obse rvations. In this talk\, I will introduce an example of the integrated ex perimental and theoretical framework that can successfully capture the co mplex mechanical response of structured fluids. As I will demonstrate in my talk\, this powerful approach not only improves our understanding\, bu t also provides guidelines to develop superior materials for critical ene rgy and environmental challenges.

For exampl e\, the turbulent drag force acting on the ocean liners accounts for more than 80% of the total energy expenditure. As such\, understanding the fu ndamental wall-bounded turbulent flow and achieving turbulent drag reduct ion have been a long-time pursuit for both scientists and engineers. Over the past several decades\, although many promising drag reduction techni ques have been developed (e.g.\, by employing a passive super-hydrophobic surface)\, sustainable drag reduction remains a fundamental challenge. I n this talk\, I will present a novel dynamic free-slip surface method tha t can reduce the turbulent drag force by more than 40%. This method emplo ys an array of air-water interfaces that are attached to the wall boundar y\, and dynamically oscillates the free-slip interfaces at the desired fr equency and amplitude. The dynamic free-slip surfaces substantially modif y the momentum and energy transfer processes within the turbulent flow. T he turbulent vorticity and shear motions were effectively lifted away fro m the wall boundary and a counterintuitive local propulsion force (rather than drag force) was generated. In addition\, as shown by an analysis of the energy exchange process\, the turbulent flow in the regions close to the wall boundary partially re-laminarized through an inversed energy ca scade process. These physical observations all support the existence of a strong drag reduction effect.

One of the seeming paradox es of deep learning is their uncanny ability to generalize to unseen data \, even though they have orders of magnitude more parameters than the tra ining data and can perfectly "interpolate" the training set. It is now be ing recognized that this generalization ability is due to the implicit re gularization that is inherent to the stochastic gradient descent (SGD) al gorithms that are used to the train them and which allows one to find "go od" interpolating solutions. In this talk\, we shall review these results and further introduce a family of algorithms called stochastic mirror de scent (SMD) which allows one to choose arbitrary (implicit and explicit) convex regularizers. In particular\, we show that explicit regularization yields far superior generalization performance over SGD on noisy data se ts. We further show that\, with appropriate explicit regularizers\, it is possible to significantly prune networks\, or to quantize each parameter to a small number of bits\, without sacrificing appreciable performance.

AERPAW supports large-scale outd oor advanced wireless experiments with autonomous unmanned aerial and gro und vehicles (UAVs/UGVs) and it is remotely accessible by the nationwide research community. Users of AERPAW have the opportunity to design and ra pidly prototype next-generation wireless technologies\, systems\, and app lications in both emulated and real-world environments. This talk will re view the overall scope\, and existing outdoor infrastructure including ei ght dedicated fixed nodes (towers\, rooftop nodes\, and a light pole) and their capabilities\, as well as future plans for the AERPAW project. We will describe various different experiment examples involving software-de fined radios\, a commercial Ericsson 4G/5G network\, RF sensors from Keys ight\, and a smart agriculture system with various LoRa gateways and sens ors\, all of them interacting with autonomous UAVs and UGVs in a large-sc ale outdoor environment. We will overview our digital twin that allows AE RPAW users to exclusively design their outdoor experiments in a container ized virtual environment. We will also provide various research examples carried out on the platform since AERPAW declared general availability in November 2021.

From rece nt knowledge of the channel\, new applications and AI/ML opportunities be come clear. The talk highlights advances in modeling the spatial and tem poral nature of radio channels\, including the impact of antenna patterns and received signal envelopes of received signals\, thereby offering ins ights into phenomena that can be used in learning models for artificial i ntelligence (AI) to predict signal behavior in real-world channels. Speci al emphasis is given to the relatively new Two-Wave With Diffuse Power (T WDP) distribution that encompasses Raleigh and Rician fading as special c ases\, and repeatable measured phenomenon of diffraction effects when a r eceiver encounters an object that physically begins to block a radio pat h. New approaches that learn the directions of arrivals and the extent of multipath from simple narrowband envelope measurements\, and how to opti mize and learn channel behaviors from ray tracing are also presented\, th us offering insights into promising ML/AI approaches to physical layer pr ediction and learning.

Regardless of the specific application\, one central goal is to shape the network's collective behavior through the design of admissible local decision-making algorithms. This is nontrivial due to v arious challenges such as local connectivity\, system complexity and unce rtainty\, limited information structure\, and the complex intertwined phy sics and human interactions. \n In this talk\, I will present our recent progress in formally advancing the systematic design of distributed coord ination in network systems via harnessing special properties of the under lying problems and systems. In particular\, we will present three example s and discuss three types of properties\, i) how to exploit network struc ture to ensure the performance of the local controllers\; ii) how to use the information and communication to develop distributed learning rules\; iii) how to use domain-specific properties to further improve the effici ency of the distributed control and learning algorithms. We will also dis cuss challenges and issues arising from these solutions.

To complete tasks\, robots must manage a complex\, interconnected autonomy stack of perception\, pl anning\, and control software. While machine learning has unlocked the po tential for full-stack end-to-end control in the real world\, these metho ds can be catastrophically unreliable. In contrast\, model-based safety-c ritical control provides rigorous guarantees\, but struggles to scale to real systems\, where common assumptions\, e.g.\, perfect task specificati on and perception\, break down. \n \nHowever\, we need not choose between real-world utility and safety. By taking an end-to-end approach to safet y-critical control that builds and leverages knowledge of where learned c omponents can be trusted\, we can build practical yet rigorous algorithms that can make real robots more reliable. I will first discuss how to mak e task specification easier and safer by learning hard constraints from h uman task demonstrations\, and how we can plan safely with these learned specifications despite uncertainty. Then\, given a task specification\, I will discuss how we can reliably leverage learned dynamics and perceptio n for planning and control by estimating where these learned models are a ccurate\, enabling probabilistic guarantees for end-to-end vision-based c ontrol. Finally\, I will provide perspectives on open challenges and futu re opportunities\, including robust perception-based hybrid control algor ithms for reliable data-driven robotic manipulation and human-robot colla boration.

In recent years\, the fields of biomechanics and clinical rehabilitation have informed the development of wearable devices and assessment tools that aid in rehabili tation and in maintaining mobility. Wearable exosystems are assistive dev ices that can target weakness in a specific joint or muscle. However\, op timizing these devices for performance across individuals\, tasks\, and e nvironments\, and understanding their interaction with wearers across the se different scenarios remains an active area of research. In this talk\, I will discuss my work using exosystems\, along with principles from mot or learning and biomechanics\, to deliver targeted robotic resistance tra ining for gait recovery in people post-stroke. I will then discuss effort s to move these systems into the real-world through data-driven estimatio n of key biomechanical outcome measures. Finally\, I will conclude with h ow these data-driven methods translate to other populations in the commun ity to assess movement and prevent injury\, such as female athletes at-ri sk of anterior cruciate ligament injury.

As these systems grow in co mplexity and scale\, the challenge of achieving optimal coordination beco mes increasingly difficult. The first part of the talk will focus on tack ling scalability issues by leveraging network structure. I will discuss h ow leveraging spatially-exponential decaying (SED) structures in networke d systems enables scalable and near-optimal decentralized control. We wil l show that under certain mild assumption\, the optimal controller also d emonstrates a similar SED structure\, which leads to theoretical guarante es for efficient distributed strategies and offers practical insights for large-scale coordination. The second part of the talk will focus on effi cient Nash equilibrium seeking for multi-agent systems. The key element g uiding our approach is the concept of 'marginalized environment' which pr ovides more flexible algorithm design and tractable theoretical analysis. Building upon this notion\, we introduce a policy-gradient algorithm wit h provable sample complexity guarantees. Lastly I will briefly present ou r work on several applications such as green buildings and multi-robotics and outline a roadmap for future work including closing the loop between theory development and applications for AI-enabled multi-agent societal systems.
