Research interestsWe work on how collective dynamics in physical and biological systems can generalize past experiences, i.e., learn, and respond differently to future inputs. This themes often requires combining work in quantitative biology, non-equilibrium dynamics, and theoretical computer science.
Current work includes: 1. Biological learning and adaptation in changing environments (in circadian clocks with the Rust lab, in molecular evolution with the Wang and Ranganathan labs) 2. Learned behaviors in materials (soft matter, molecular systems with the Winfree lab, active materials). Openings: If you are interested in working on such themes as a postdoc, graduate student or undergrad, contact amurugan@uchicago.edu. Funding: Our work is primarily supported by the NSF and a Simons Foundation Investigator award. Lab members have been supported by the James S. McDonnell Foundation and NSF fellowships. |
