Tissue Ecology and collective multicellular computation

Ecology is an interdisciplinary field that studies how living organisms interact with each other and their ever-changing surrounding environment, as well as how such interactions drive decisions, behavioral outcomes, and evolution at both organismal and environmental levels. Many ecological principles are shared by different complex systems as they influence system level equilibrium, homeostatic state, and existence.

Competition between cells control the outcome of tissue repair in liver (regeneration vs fibrosis).

Gut produced serotonin modulate the competitive cell interaction in liver.

Organisms co-develop, collaborate, generate heterogeneity. These processes ensure success for the collective success and survival that is transferred at multiple scales. We use these principles to engineer bottom-up novel multicellular systems that can perform meaningful tasks with immense biomedical impacts . 

Image analysis to study cellular neighborhoods

Some years ago we have also studied how cellular competition in liver lobules can control the balance between healthy tissue regeneration and fibrosis(unhealthy wound healing). We observed gut-produced serotonin control the landscape of cellular competition in the liver (Nat Med 2011).


We are using multicellular systems to better understand tissue ecology. More specifically we study how tissue neighborhoods compute the collective information to shape the identity and destiny of individual player and how we can perturb the system and control this outcome.
