Christine Z. AlvaradoChristine Z.  Alvarado, Ph.D.
Associate Professor – Poultry Processing and Products

Research areas include improving meat quality and process efficiency for poultry processors, antemortem and postmortem causes and remediation techniques of poor quality meat, marination ingredients and process control, determining functionality of non-meat adjuncts in further processed poultry, egg quality and safety, Listeria control in ready to eat poultry products, pre-harvest and post-harvest food safety interventions.

Gregory S. ArcherGregory Archer, Ph.D.
Assistant Professor & Ext Specialist – Breeder/Hatchery Management, Animal Behavior

Research is focused in the areas of animal behavior/welfare and stress physiology.  Research utilizes behavior and physiological measures to investigate the effects of environmental conditions, nutrition, management practices, and housing design on the health, production, and welfare of poultry.  The primary goal  of the research is to investigate current practices, identify problem areas, and develop new methods to optimize the production, health and welfare of poultry.

Giridhar AthreyGiridhar Athrey, Ph.D.                                Dr. Athrey’s Lab Homepage
Assistant Professor – Avian Genetics & Functional Genomics

The main focus of our lab is to address fundamental questions relevant to evolution, genetics and conservation of both domesticated and wild bird species. Research projects in our lab utilize field and experimental studies coupled with genomic and computational tools to illuminate the genetic basis of quantitative traits, functional aspects of communicable and vector borne diseases, innate immunity and population genetics of avian and non-avian taxa. The broader implications of our research includes the generation of knowledge and innovative tools for improving animal, human and environmental health.

Chris BaileyChristopher A. Bailey, Ph.D.
Professor – Poultry Nutrition

Research areas include actively seeking to reduce the environmental impact of poultry production primarily by seeking improvements in nutrient utilization.  Strategies include seeking improvements in ingredient processing and feed manufacture, evaluation of alternate rearing/feeding strategies such a continuous multiphase feeding, dietary incorporation of exogenous enzymes, use of prebiotic materials such as mannan oligosaccharides (MOS), and use of antibiotic like growth promoters.

Luc R. BerghmanLuc R. Berghman, Ph.D.
Associate Professor – Immunology, Endocrinology & Transgenics

Research areas focus on acquiring fundamental new knowledge of the avian immune system and applying this new knowledge toward the development  of new immuno-biotechnological tools.  Research projects include the study of the immune response in the chicken, especially the function of antigen presenting cells (such as the dendritic cells) in activating the humoral immune response and the developement of chicken egg yolk antibodies, monoclonal antibodies and recombinant antibodies for diagnostic, prophylactic and therapeutic purposes.

John BJohn Carey. Carey, Ph.D.
Professor – Production, Management

Research areas include layer management, egg production and environmental stewardship.  Past efforts have focused on methionine sources and broiler excreta odor, fate of nitrogen in broiler production and nutrient buildup in broiler litter  and the role of dietary threonine on egg component yield, composition and functional qualities.

Craig CoufalCraig Coufal, Ph.D.
Associate Professor & Extension Specialist – Animal Waste & Litter Management
Associate Department Head for Extension & Extension Program Leader

Research area focus on poultry waste management.  Specific areas of investigation include litter and manure management, odor control, plant nutrient utilization, pathogen reduction, ammonia emissions reduction, composting of wastes and alternative waste management strategies.

Tri DuongTri Duong, Ph.D.
Assistant Professor – Microbiology

Our research seeks to develop a mechanistic understanding of microbial functionality in probiotic and bioprocess applications with the overall goal of developing microbe-based biotechnology solutions for animal agriculture, bioprocessing, and human health.  Particular areas of focus include the development of microbial biocatalysts, bacterial colonization of the gastrointestinal tract, biotherapeutic delivery and bacterial genetics.

Jason LeeJason Lee, Ph.D.
Associate Professor – Poultry Management

Research areas include improving efficiency and nutrient utilization of poultry production through dietary alterations utilizing new technologies including exogenous enzymes, vaccinations, probiotics, and prebiotics to reduce the cost and environmental impact of poultry meat and egg production.

Audrey McElroyAudrey McElroy, Ph.D.
Professor & Extension Specialist – Intestinal Health

Our research is focused on intestinal health and integrity with the objective to minimize the impact of enteric pathogens on growth and performance in commercial broilers and turkeys. Goals are to investigate intestinal mechanisms of immunity to pathogens and how they can be modulated by vaccination, dietary/nutritional strategies, or other means to improve intestinal integrity during enteric disease challenge.

Suresh PillaiSuresh Pillai, Ph.D.                                     Dr. Pillai’s Lab Homepage
Professor, TAES Faculty Fellow – Food  and Environmental Microbiology

Research areas include ecology of microbial pathogens, pathogen detection methodologies, pathogen prevention and reduction equipment/process engineering, microbiology and waste management.  Strageties include the adaptation of E-Beam and X-ray technologies for food safety, phyto-sanitary applications and other applications.

Sanjay ReddySanjay Reddy, Ph.D.
Professor – Virology and Disease

Research areas include poultry health with special emphasis on vaccines, and host-pathogen interaction.  Specifically the Marek’s disease virus with an emphasis in genomic/epigenetic regulation of Mareks disease virus genes and the development of the Marek’s disease virus as a vaccine vector.

Rosemary L WalzemRosemary L. Walzem, Ph.D.
Professor – Nutritional Biochemistry

Research is focused on fundamental and applied issues in lipoprotein biology in humans, poultry and other comparative species.  Research projects address basic mechanisms of yolk formation, functional qualities of yolk-precursor lipoproteins and physiological factors within the hen that influence yolk formation.  Research related to human nutrition emphasizes those dietary factors and physiological processes that mitigate or initiate atherosclerotic cardiovascular disease (ASCVD).
