Julio Correa, Associate Professor of Animal Nutrition

Nutrient digestion and biochemistry and its effect on biological mechanisms of animal growth.


Emphasis on nutrient intake, digestion and absorption; biochemistry of nitrogenous compounds in the rumen; and growth and body composition (fat and protein) of beef cattle, sheep and goats.
Josh Herring, Associate Professor of Food Biochemistry

Food Biochemistry: chemical, microbiological and physical reactions that take place in food (post-harvest) such as oxidation, pH change, drying (freeze- and spray-drying) effects, fermentation and pathogen and LAB growth.

Utilization of cutting edge equipment such as high performance liquid chromatography, scanning electron microscope, texture analyzer, spectrophotometer and fermentation systems.
 Adding value to undervalued or underutilized products, such as waste streams or low quality products.
Armitra Jackson-Davis, Assistant Professor of Food Microbiology/Safety

Investigating the microbiological safety of food products labeled as “natural” or organic

Evaluation of natural antimicrobials
Lamin Kassama, Assistant Professor for Food Bioprocess Engineering

Expertise covers food quality and safety with emphasis on food microstructure, thermophysical and rheological properties of foods, heat and mass transfer of foods, food packaging, supercritical fluid extraction of bioactive components from plant matrix, food product development and process optimization, postharvest application on fruit and vegetables, application of emerging technologies (pulsed electric field (PEF), pulsed ultraviolet (UV) irradiation, ultra-high pressure) in food processing to enhance food quality and safety, fermentation and bioprocessing of food products.

Koffi Konan, Research Associate Professor of Plant and Microbial Biotechnology

Crop quality improvement using Cell and/or organ Culture and Genetic Engineering technologies. This involves in vitro culture of plant cells and/or organs to produce plants with new characteristics, the design and cloning of recombinant DNA in bacteria, and the utilization of recombinant DNA in plant genetic modification via Agrobacterium and/or biolistics.
 Current topics; 1) Enrichment of peanut in Essential Amino Acids, 2) Development of in vitro culture methods for yam, 3) Study of transcriptome in peanut and yam to design better strategies for the genetic enhancement of these crops.
