Research Interests
I'm a fish guy-I study how fish do what they do. I'm also a fat guy-I'm interested in what cells and organisms do with fat. Finally, I'm a temperature guy-I spend time thinking about how temperature affects cell function. Together, these things mean that I study the cell physiology of fish with different body temperatures, and different fat metabolisms. In the past I've worked on very cold fish (Antarctic fish) and fish that are cold seasonally (like striped bass). I've also worked on some fish that keep parts of their bodies warm (blue marlin). Where does fat come into the picture? Cold fish tend to accumulate fat. Why? How? That is some of the focus of our current research. We study proteins that may help the cell to burn fat, move it around, get rid of it or deposit it. Specifically, we are working on leptin, and enzymes that burn fat. Current directions include characterizing how leptin works in zebrafish and carp.
Currently I am working with 3 doctoral students in the new Integrated Bioscience PhD program. Donnie Copeland is working on how leptin affects carp's physiology in their environment. He is particularly interested in response to stress and cold. Hope Ball is working with myself, Joel Duff, and Hans Thewissen at NEOUCOM. Her project is investigating the biology of leptin in Bowhead whales. Mark Dalman will join the lab this Fall, and he is going to be working on leptin physiology in zebrafish.
Common techniques we use in the lab include proteomics, quantitative PCR, immunoblotting, microinjection of morpholino oligonucleotides, etc. (the common molecular bag of tricks).
