Prof. Leonard’s background includes feedback control theory, nonlinear dynamics, geometric mechanics, and robotics, where she has made contributions both to theory and to application. She studies and designs complex, dynamical systems comprised of many interacting agents, including, for example, animals, robots, and/or humans that move, sense, and decide together. Her research program emphasizes the development of analytically tractable mathematical models of collective dynamics that provide the systematic means to examine the role of feedback (responsive behavior), interconnection (who is communicating with whom), heterogeneity (individual differences) in the behavior, learning, and resilience of groups in changing environments.

Leveraging mathematical models, Leonard has studied mechanisms of collective behavior in fish schools, bird flocks, honeybee swarms, and ant colonies, and she has designed rules for distributed robotic vehicles to perform collaborative tasks ranging from adaptive ocean sampling to trash collection in human-populated spaces. A former student of dance and life-long dance enthusiast, she has grown increasingly interested in intersections with dance and composition.

Himani Sinhmar’s research focuses on modeling the dynamics of cooperation and collective intelligence to better understand and shape behaviors engineered systems such as robot swarms. She earned her PhD from Cornell University in 2024, after completing her Bachelor’s and Master’s degrees in Technology from IIT Bombay in 2019. Her doctoral work involved developing certifiably safe controllers and motion planners for resource-constrained robotic systems. Sinhmar’s interdisciplinary approach spans control theory, non-linear dynamics, collective intelligence, and formal methods, with the goal of creating practical, theoretically sound solutions to improve the safety and reliability of robots in unstructured, dynamic environments.

I am broadly interested in multi-agent dynamical systems, control theory, and robotics. My current research focuses on the distributed control of opinion patterns on signed networks of agents.

Broadly interested in feedback control, robotics, and people, my research focuses on what processes and control strategies can be used to aid human-robot interactions and encourage collaboration. I am currently exploring the use of opinion dynamics to dictate reactive motion control and collision avoidance for on-ground robots to safely pass by humans.

My research interests lie at the intersection of multi-agent systems, human-robot collaboration, and stigmergic construction. Specifically, I explore how heterogeneous teams consisting of both humans and robots can design and build creative, high-performance structures by making local on-the-fly decisions.

My research interests lie at the intersection of machine learning, optimization, multi-agent systems, and control theory, primarily in (deep) multi-agent reinforcement learning (MARL) and efficient decentralized decision-making. I am currently working on new algorithms that allow learning agents to solve game-theoretic tasks while using communication to promote coordination and cooperation.

Student Profile

My research interests are at the intersection of robotics, control, and machine learning. I’m interested in questions about how robots perform cooperative tasks, specifically in space applications. Currently, I am working on using learning techniques to predict the dynamics of 3D rigid-body objects for the purposes of model-based control.

My research focuses on dynamical systems, network models, and the influence of human behavior on the spread of epidemics and other contagion processes. I study how individual decision-making and the transmission of information affect outcomes on both physical and informational networks. Using mathematical modeling and analysis, I aim to understand the feedback between behavior, information flow, and disease dynamics, and to identify mechanisms that promote or hinder containment and coordination in complex systems.

I am interested in designing and controlling of physics-based deformable structures and soft robotics. Specifically, my research interest is using topological optimization and inverse learning to use physics-based mechanisms in designing soft robotics. In addition, I am passionate about controlling the soft robotics and using reinforcement learning to achieve controllable locomotion.
