Sam Vohsen is a graduate student in the Biology program at Penn State advised by Dr. Chuck Fisher and Dr. Iliana Baums.  He received his B.S. dual degree in Biology and  Applied Mathematics from Saint Louis University in 2013.  As an undergraduate, he studied the physiological mechanisms painted turtles utilize to overwinter in ponds and used GIS techniques to predict the response of stream fish distributions to climate change. Now, he studies the effects of natural and anthropogenic sources of oil on deepwater coral in the Gulf of Mexico using metabolomics, stable isotopes, and the microbiome.  On the Falkor, he will be assisting with biological sampling and onboard experiments with invertebrates collected from vent sites.
