Me and Panaque

Hello, I am interested in biochemical specializations of the digestive tract in herbivorous fishes. The summarized question behind all of my work is: What does it take to be an herbivore for fishes?

Knowledge of the biochemical adaptations allowing herbivorous fishes to digest food (algae, plants, and even wood) that is low in nitrogen, protein, and lipid, and encased in a largely indigestible cell wall is limited, especially when compared to the vast knowledge of digestion in terrestrial herbivores. By investigating assimilation efficiencies, nutrient transport, digestive enzyme activities, and metabolic utilization of specific nutrients, I hope to expand our knowledge of digestive strategies in herbivorous fishes.

I performed my Master's research with Dr. Michael H. Horn at California State University Fullerton on herbivorous and carnivorous prickleback fishes. Springboarding from my master's work, I am now investigating the digestive physiology of freshwater herbivorous fishes.  My PhD advisor is the great Dr. David H. Evans.
