I have the great pleasure of hosting Dirk GΓΆrlich at the IGBMC this Friday, and I very much look forward to the stimulating and insightful discussions.
FRIDAY LECTURES: Dirk GΓΆrlich (Lasker Prize 2025) reveals the βdark proteomeβ and the selective sorting of molecules within the cell.
An exceptional event on Friday, January 9, at 3:00 p.m., IGBMC Auditorium.
Organized by Izabela Sumara.
A deep dive into the heart of the cell not to be missed!
