Dr. Alexandre Ponomarenko
Harvard University
Dr. Alexandre Ponomarenko is a postdoctoral researcher in the Department of Organismic and Evolutionary Biology at Harvard University. He is a physicist fascinated by plants and how they achieve the movement of large amounts of sap in the xylem. In particular, Dr. Ponomarenko is interested in how this mechanism fails during severe droughts. He will present observations of cavitation in leaves, sap channels and branches and discuss what it tells us about how cavitation propagates in plants during droughts.
All are welcome! Refreshments served at 3:00 PM.
