(Office hours, 1-2pm, Fridays LSA 3253)
TA: Bess-Carolina Dolmo, BS in Chemistry, Graduate student in Biomedical engineering
(Discussion session, Wednesday 3-4pm, room TBA)
This is a class on the physical and chemical principles by which atoms and molecules form living, moving, reproducing cells. I will supplement lectures with reading material and problem sets or written paper assignments. Grades will be based on participation in class plus take-home problem sets (approximately 40%); one mid-term (approximately 20%) and one final take home paper (approximately 40%).
Lectures will be held in SURGE 3 Room 1309 every Tuesday and Thursday from 12.10-1.30pm.
