Research Interests

My research interests lie in the areas of aquatic toxicology, ecophysiology of aquatic organisms and aquaculture. Specifically, our lab studies the impacts of stressors from both anthropogenic (i.e., pollutants, such as crude oil and metals) and natural (e.g., salinity, ammonia and temperature) sources, as well as their interactions, on aquatic organisms. We use an integrative approach to understand the mechanisms of toxicity and other stress responses, studying effects from the molecular to the organismal level. We also study the swimming and respiratory physiology of fishes and how the stressors mentioned above may impair these important physiological functions.

Recent Research

Current research in our lab includes: (1) optimizing aquaculture of the prawn, Macrobrachium rosenbergii, using spent brine from the desalination of brackish groundwater, and developing a sensitive real-time ecotoxicology system (RTES) powered by artificial intelligence that relies on metabolic rate and behavioral analysis to detect acute changes in water quality; (2) determining the swimming performance of imperiled fishes of TX to aid in construction of culverts such that resulting stream flows do not exceed their swimming capacity; (3) investigating the combined effects of hypoxia and the metal, lead (Pb), on aquatic organisms. More details on recent specific projects can be found below:
