John Del Rosario

Postdoctoral Research Associate

Dr. John Del Rosario is a postdoctoral research associate in the Department of Anesthesiology. Dr. Del Rosario was born and raised in the Dominican Republic and moved to the United States to pursue a career in science. He graduated with a Bachelor of Science and a Master of Science in neuroscience from City College of New York, and obtained a Doctorate in Biomedical Sciences from Rutgers University. 

As a postdoctoral fellow in the lab of Dr. Robert Gereau, Dr. Del Rosario is currently working on understanding how the peripheral nervous system adapts, maladapts, and remodels to sustain neuronal activity due to chronic pain conditions. Dr. Del Rosario utilized mouse and human sensory neurons and models of neuropathic pain to study the peripheral mechanisms that facilitate the transition from acute to chronic pain sensation in the context of ion channel dysfunction, pain-triggering injury, and channelopathies. 

Outside of his work, Dr. Del Rosario enjoys spending time with his family and friends, singing, dancing, and going to church, where he is an active member of the choir.
