Research Interests

Our lab's research focuses on the design of novel theoretical and computational frameworks to address open problems in science and engineering. Our approaches draw primarily from statistical physics, dynamical systems, and machine learning. We are a cognitively diverse group of scientists and engineers whose backgrounds span physics, chemical and biological engineering, materials science, statistics, scientific computing and data science. The problems we work on emerge from our own theoretical interests, as well as our close interactions with experimentalists, with whom we pursue quantitative descriptions of experimentally observed phenomena.

Currently, the lab's active research projects span (i) fundamental work on the energy landscapes of disordered systems, such as amorphous solids, spin glasses, and neural systems; (ii) the development of a unifying framework of neural dynamics, with an emphasis on modelling sensory-evoked activity in the visual cortex, and working memory representation and manipulation in the prefrontal cortex (iii) the integration of machine learning and sampling methodologies for (bio)molecular design and simulation; (iv) the development of experimentally viable approaches to measure entropy production in active matter systems; (v) the exploration of the relationship between information, order and correlations in complex systems.
