Subgroup D

Subgroup D: Evolutionary Cell Biology

Saturday, December 8, 8:30 am-12:30 pm
Room: 28 E

Organizers: Holly V. Goodson, University of Notre Dame; and Margaret A. Titus, University of Minnesota

Evolutionary cell biology (ECB) encompasses research with two complementary goals: 1) using the perspectives and methods of evolutionary biology to gain insight into cell biological processes; and 2) studying the biology and diversity of cells to gain insight into the process of evolution. These goals are unified by the expectation that studying these questions in the context of cells the basic units of life—should illuminate fundamental principles of living systems. Talks in this session were chosen from abstracts submitted in response to a request sent to the ECB community. To build this community, we are compiling a list of ECB-related talks and posters to distribute at this session. To include yours in this list, please send your presentation information to the session organizers.
