Keynote Lecture

Ursula Goodenough, Washington University

From Light to Sex to Motility to Obesity: Sharing Life with Chlamydomonas and the Chlamy Community.

Ursula Goodenough will lift up highlights of her 50 years of Chlamydomonas research, starting with photosynthesis and chloroplast biogenesis studies in Paul Levine''s lab at Harvard, followed by studies of mating, flagellar architecture and signaling, cell-wall assembly, and lipid-body formation in her own lab, all with many terrific collaborators.
