Dr. Iyengar is a long-standing Simons Visitor. His area of interest is information theory. During his visit he interacted with all faculty members of the Centre as well as with multiple Fellows and postdoctoral researchers. Most recently he is exploring the free energy costs of the dynamics and memory of physical sensors processing information. The living cell uses a variety of molecular receptors and signaling networks to read and process chemical signals. Dr. Iyengar is interested in establishing exact lower bounds, in terms of mutual information, for bimolecular information processing.
