My research focuses on the direct and indirect effects of heat stress on the Holstein dairy cow liver and mammary tissue, specifically studying how heat stress affects the mitochondria. With this research, we are trying to understand the cellular mechanisms underpinning heat stress effects on dairy cow lactation.

Our research is dedicated to evaluating heat shock protein 70 (hsp70), antioxidants — especially, those involved in the mitigation of stress induced by reactive oxygenated species (ROS), including superoxide dismutase (SOD), catalase and glutathione peroxidase (GPx) in mature, lactating range cattle during the summer months. Additional focus is placed on the influence of stress on grazing behavior and the results of implementing technologies (injectable trace mineral; ITM) on SODs, catalase and GPx.

Ultimately, we hope to find the best candidates for range cellulose conversion as well as strategies to implement in husbandry practices to promote efficiency in this capacity.

My research addresses the need to develop effective mitigating strategies towards multiple water borne contaminants that are prevalent in U.S. aquaculture systems. Specifically, focused on the development of functional feed (bentonite and vitamin C) to mitigate the adverse effects on performance and health status of fish due to natural water metal (Iron) toxicity and nitrogenous metabolic waste (ammonia) produced by fish. Major objective of my research is to determine the potential benefits of dietary bentonite and vitamin C as a feed additive on ammonia and mineral elimination by fish as well as on production performance and integrated physiological, metabolic and cellular responses.
