Biophysics Journal Club
Jay Tang's Biophysics Laboratory website can be found here| The biophysics journal club is designed to show relevant literature to our faculty and graduate students. Everyone is welcome. Our interests are biased towards protein self assembly and interactions, cellular systems, cytoskeletal networks, protein diffusion, lipid physics, bacteria motion, and any other soft matter type literature. |
We meet every Friday at 12:00 pm in room B&H 410.
Come a few minutes early for sandwich and drinks. |
