Jinae RoaPh.D. Graduate | jnbroa@ucsd.edu

Dr. Jinae Roa is a native of southern California. She received a BS in Biology from UC Santa Barbara and an MS in Biology from CSU Long Beach, where she specialized in muscle physiology of marine fish. Dr. Roa completed her doctoral research as a member of the Tresguerres Laboratory and received a PhD in Marine Biology from Scripps Institution of Oceanography at UC San Diego, where she specialized in acid-base physiology of marine elasmobranchs. She continued her training as an NSF Postdoctoral Research Fellow in the laboratories of Professors Martin Tresguerres and Colin Bauner at Scripps Institution of Oceanography and the University of British Columbia, then as an NIH IRACDA Postdoctoral Fellow in the laboratories of Professors Susan Taylor and Dorota Skowronska-Krawczykat UC San Diego.

Research Interest:

  • Acid-base sensing and regulation
  • Cell physiology
  • Energy metabolism

At SIO, Dr. Roa’s research focuses on mechanisms for acid-base sensing and regulation by the acid-base sensor soluble adenylyl cyclase (sAC) and energy metabolism in marine animals.
