Environmental physiology) Sample web pageThe main components of my research program involve using a fish's relative ability to swim to understand how suited it is to its environment and understanding how natural selection and acclimatization processes influence a fish's swimming ability. I also do some thermal biology, work on individual fish hypoxia tolerance and work on the biology of loricariid catfishes that breath air and are adapted to include wood in their diet.

The major question of my European Sea Bass program is: Do laboratory measures of performance predict survival of Sea Bass (Dicentrarchus labrax) in a simulated natural environment?
This work takes place primarily
in the lab of Dr. Guy Claireaux in Brest, France and at the mesocosm facility in L'Houmeau France. Here you see Guy trying to monopolize the beer supply in Barcelona. For more information about my European Sea Bass program, please click the following link:
Another main thrust of my research program has been aimed at understanding how natural variations in flow or variations in flow induced by urbanization influence the biology of a small stream cyprinid, the blacknose dace.

Here you see former undergraduate and graduate research students Kirk Gastrich and Portia Gotwalt seining dace from Gwynn's Falls, a suburban stream in Baltimore Co.
Recently, I have also been invesigating whether urbanization has influenced the thermal biology of this species. For more on my blacknose dace research please go to:
Currently in my lab, we also have projects aimed at understanding the impact of hypoxic zones (dead zones) in estuarine systems on fishes of the family Moronidae. This work began with European sea bass in the lab of Dr. Guy Claireaux in Brest, France, but continues in my lab with striped bass (rockfish). Using an individual approach that has been a hallmark of my research career, we are trying to find factors that contribute to an amazing level of intraspecific variance in hypoxia tolerance in both of these species.

Finally, I've done some work on these interesting fish:
