Physic major Nat Mason did research over the summer with professor Ovidiu Lipan in the field of Biological physics. Nat is working on the heat shock system in mammalian cells. He is looking for ways to undderstand the response of the cells to a double heat pulse. This research will open new perspectives on heat shock memory (thermotolerance). Nat has worked with professor Lipan since his first year, and continues his research this fall.
