Teaching
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.

Mallory is broadly inspired by developing mathematical approaches to decision making and optimal control under uncertainty, particularly to solve problems arising in technological, ecological, and sociological contexts. As an applied mathematician, she aims to use these models to reveal insights into the “why” behind physical phenomena and provide recommendations for the design or improvement of such systems. Mallory completed her B.S. in Mathematics and Applied Physics at Rensselaer Polytechnic Institute (RPI) in December 2018, followed by her Ph.D. in Applied Mathematics at Cornell University in summer 2025. At Cornell, Mallory’s doctoral research focused on developing dynamic programming based frameworks for optimal control under uncertainty to determine driving strategies in the face of limited traffic signal timing information, to compute enhanced driving directions that also provide lane change timing and effort information, and to better understand when predators in the animal kingdom might decide to utilize motion camouflage tactics while pursuing prey. At Princeton, Mallory is both extending and broadening these mathematical approaches to enhance our understanding of collective behavior in large scale systems of interconnected individuals (e.g., living organisms, technological devices) and to deepen our intuition about life-event timing in ecological contexts.

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.

My main research interests relate to dynamical systems, control theory, information theory, distributed systems and optimization. I am also very interested in exploring engineering applications that take inspiration from biological systems.

Daniel Richard Levy
Department: PACM
Office: 218 Fine Hall
Email: dl8529 [at] princeton.edu
I develop rigorous mathematical theory for biological and social complex systems, focusing on how agent misperception and individual heterogeneity influence collective dynamics and emergent phenomena. My work draws on tools from dynamical systems, applied analysis, probability, and related areas to bridge mechanisms across scales.

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.

Email: m.ordorica [at] princeton.edu
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.

My research focuses on the intersection of machine learning and multi-agent systems. Currently, I study statistical approaches for modeling emergent properties in swarm robotics and cellular morphogenesis as well as machine learning methods for training populations of cooperative agents.
