Biological Physics & Physical Biology Seminar
Seminar Information
BP/PB seminars are held most Fridays. The first talk begins at 8 am pacific/ 9 am mountain/ 10 am central/ 11am eastern in the US, which is 4 pm in the UK/ 5 pm in central Europe/ 9:30 pm in India/ 12 midnight in Beijing. The second talk starts at half past the hour.
The goal of the series is to highlight interesting current research in biophysics, broadly defined.
Email list signup and talk zoom information: Click here to join the mailing list and/or volunteer to speak. Zoom information for each seminar will be shared with the mailing list on Wednesdays, and again in a reminder email on Fridays shortly before the talks begin.
Past talk videos: The BPPB YouTube channel has recordings of selected past talks.
Organizers: A rotating cast of organizers has helped to sustain this seminar series over the past few years. The current team is: Sonya Bahar, Jing Chen, Moumita Das, Andrej Košmrlj, Enkeleida Lushi, and Ashok Prasad.
