Curriculum Vitae
​Our lab explores comparative vertebrate physiology, including developmental biology, fish thermal biology and the cardiovascular system. We are interested in the biology of fish and reptiles, including Crocodilians, equatorial tropical fishes, fishes in southern California, embryonic reptilian cardiovascular systems, and freshwater fishes. Please check out the news items, below, for some recent information on what we're up to!

• Anay Ochoa has some great accomplishments in 2021. Great job, Anay!
  • ​Anay performed an REU at UC Berkeley as a part of Christopher Martin's lab during summer 2021. Anay was a Finalist for the CSU-wide Student Research Competition held virtually at California State University Polytechnic, Pomona on April 30-May 1, 2021. She was chosen as a finalist based on our CSUSM competition, which we call the "Symposium on Student Research, Creative Activities, & Innovation".​​ Anay presented an abstract at Experimental Biology April 27-30, 2021. She was awarded a CSUSM Library Award for Undergraduate Research and Creative Activity. ! ​​Anay Ochoa's research was highlighted on the Life Lines blog, sponsored by the American Physiological Society, check out the write up here:  lifelinesblog.com/2021/05/03/hatchling-vs-the-egg-which-is-a-better-predictor-of-growth/
