Kieth Cheng, Professor and Chief of the Division of Experimental Pathology at Penn State will be discussing his research on skin color. 

He did studies with Zebrafish to find a connection between light skin and dark skin.

His research has gone a long way towards finding the strand inside humans that causes skin color and ways to help with skin cancer in the future.  

If you are interested in the science behind your skin this is the talk for you.
