My principal research interests concern osmoregulation and the renal, gastrointestinal, and hepatic mechanisms that vertebrates use to cope with their environment, but I have also dabbled in animal behavior, bioinformatics, evolutionary genetics, genome evolution, metabolism, nutrition, and respiratory physiology.  My peer-reviewed publications (listed alphabetically by surname) are below with a link to the PDF.
