Christian von Hehn MD PhD

Research Fellow

vonHehnBackground
Having graduated from medical school in 2003 at Kiel University, Germany, I worked with Dr. Leonard Kaczmarek. In 2004, I went on to the neuroscience graduate program at Yale University, and received my PhD in 2009 studying nociceptive TRP channels with Dr. Sven Jordt.

Research Interests
I am interested in the interaction between the peripheral nervous system and the immune system during acute and chronic inflammation. Using electrophysiological and imaging methods, my aim is to elucidate signaling molecules and cell types involved in sensory neuronal sensitization and immune cell activation.
