Currently a comparative physiologist and postdoctoral associate at Weill Medical College of Cornell University, Tresguerres conducts research on a wide range of organisms. His interests include the evolutionary relationships between basic cellular functions and complex “whole animal” physiology. Augmenting Scripps’ leadership in ocean acidification, Tresguerres’ research at Scripps will include how marine organisms sense and adjust to acid/base disturbances arising from environmental and metabolic variations in carbon dioxide, protons, and bicarbonate ions. His studies have included physiology, cell and molecular biology and biochemistry, but also cover marine invertebrate ecology, marine mammal tax­onomy, and fisheries. Thus, Tresguerres has indicated that these experiences have trained him to always consider the “big picture,” even while studying processes at the molecular level.
