"Stochastic differential equations (SDEs) provide a flexible framework for modeling time series, dynamical systems, and sequential data. However, learning SDEs from data typically relies on adjoint sensitivity methods, which require repeated simulation, time discretization, and backpropagation through approximate SDE solvers, leading to significant computational overhead and limited scalability. We introduce SDE Matching, a simulation- and discretization-free approach for learning stochastic dynamics directly from data. Building on recent advances in score matching and flow matching for generative modeling, we extend these ideas to the dynamical setting, enabling direct learning of SDE drift and diffusion terms without numerical simulation. SDE Matching replaces solver-based training with a regression-like objective defined on transformed data samples, eliminating the need for backpropagation through stochastic trajectories. Empirically, SDE Matching achieves accuracy comparable to adjoint sensitivity-based methods while substantially reducing computational cost, offering a scalable alternative for learning stochastic dynamical systems. We demonstrate these results across a range of synthetic and real-world dynamical modeling tasks."

Information design is a seminal concept in economics wherein a party with information advantage can strategically reveal this to influence the actions of a rational decision-maker. This talk centers on my efforts to bridge this model to emerging computational and machine learning paradigms. While the classic model assumes that only the quantitative structure of information matters, behavioral economics and psychology emphasize that the framing of information also plays a key role. My recent work formalizes a language-based notion of framing for information design and combines analytical methods to design information structures with LLMs to optimize the language/framing. I explore, both theoretically and empirically, when this LLM-augmented approach is tractable. I will also discuss a second work that uses information design as a light-weight approach to content moderation on social media. Doing so requires a new framework where the information advantage originates from a machine learning model and the interaction is dynamic with long-term intervention effects. I will conclude by connecting these threads to my broader research agenda on strategic decision-making in multi-agent systems.

Stochastic optimal control problem with a final constraint provides a natural way to construct a Schrödinger bridge between two distributions, making it well‑suited for generative modelling. In this problem, the optimal control can be expressed through the Schrödinger potential, which depends on the target distribution — typically unknown in practice. We address the problem of estimating this potential from finite samples. Focusing on estimators that minimize the empirical Kullback Leibler (KL) divergence, we study their generalization abilities. Despite the loss function’s unusual structure, we show that it exhibits favourable geometric properties under mild assumptions that hold for a broad class of target distributions. We derive non‑asymptotic, high‑probability upper bounds for the potential estimation accuracy, measured in terms of excess KL‑risk. In the second part of the talk , we show that the Schrödinger system could be rewritten in terms of a single positive transformed potential that satisfies a nonlinear fixed-point equation and estimate this potential by empirical risk minimization over a function class. The talk is based on the joint work with D. Belomestny, N. Puchkin and D. Suchkov.

Historically, tools developed for statistical inference and control have relied heavily on the independence of the samples. However, the advent of methods to continuously draw samples from a single source makes them dependent. Statistical inference is far more challenging for dependent data without assumption of strict structures like auto-regressions or moving average. This talk concerns regenerating stochastic processes; a structure richer than simplistic dependent models like AR/ARIMA, but still amenable to rigorous statistical theoretical guaranteed in both time homogenous, and time inhomogeneous settings.

As robotic systems grow more capable and ubiquitous, their increasing scale and complexity necessitate a shift toward robust, scalable controllers and automated synthesis methods. My group has approached this challenge by turning to distributed (multi-agent) reinforcement learning (MARL) approaches, with an emphasis on understanding and eliciting emergent coordination/cooperation in multi-robot systems and articulated robots (where agents are individual joints). There, our focus lies in improving information representations and neural architectures, as well as devising learning techniques that can help them explore their high-dimensional joint policy space, to identify and reinforce high-quality policies that naturally fit together towards team-level cooperation. In this talk, I will discuss the three main areas my group has been investigating: imitation learning, modularized/hierarchical neural structures, and learning scaffolding. I will describe these techniques within a wide variety of robotic applications, such as multi-agent pathfinding, autonomous exploration/search, traffic signal control, collaborative manipulation, and legged loco-manipulation. Finally, I will also briefly touch on some of our ongoing and future work. Throughout this journey, my goal will be to highlight the key challenges surrounding learning representation, policy space exploration, and scalability/robustness of learned policies, and outline some of the open avenues for research in this exciting area of robotics.

This talk explores the evolution of traditional UX and design strategies in the era of artificial intelligence, with a focus on cities and communities—drawing from Successful User Experience: Strategies and Roadmaps (2nd edition) and Usability for the World: Building Better Cities and Communities. It integrates ethical AI frameworks like transparency, fairness, accountability, beneficence, and non-maleficence to evolve "smart" cities into "wise" ones, addressing biases, corporate overreach, and digital divides through human-centered roadmaps such as inclusive design sprints and accountability audits. These strategies align with UN SDG 11 by enabling equitable, sustainable urban planning via participatory tools and fair resource allocation.

This talk introduces a novel nonparametric inference framework for functional data having sample paths of bounded variation, with applications in a variety of complex statistical settings. The main application will be to wearable device data collected in a Columbia-based study of an experimental therapy for mitochondrial disease, a group of disorders that affect the body's ability to produce energy. Specifically, we provide the first clinical application of a novel, bias-adjusted outcome measure of acceleration across a range of subjects' activities to assess nucleoside therapy for thymidine kinase 2 deficiency, an ultra-rare autosomal recessive mitochondrial disease.
