Theory of quantitative genetics and statistical methods for analysis of genomic data, with emphasis in Bayesian approaches. Statistical learning methodology.

Hasan Khatib - Molecular (cattle, infertility, nutrition, epigenetics)
Hasan Khatib
Research Interests: Infertility is a serious problem in humans and other mammalian species. Embryonic loss is a major contributor to infertility. The objectives of my research are to identify and characterize genes and pathways for embryo development, female fertility, and male fertility using the cattle model. In the last few years, a unique in-vitro fertilization experimental system was established in my lab that enabled us to identify many genes and pathways involved in fertility traits ( In addition, we are investigating the roles of imprinted genes and epigenetic modification in early embryonic development. Another focus of my research is the investigation of the effects of maternal diets before and during pregnancy on fetal traits through gene expression and epigenetics.
Brian Kirkpatrick - Molecular (cattle, multiple ovulation and twinning, Johne's disease)
Brian Kirkpatrick
Research Interests: Molecular genetics of multiple ovulations and twinning in cattle; Genetic regulation of Johne's disease
Guilherme Rosa - Quantitative Genetics & Statistical Methods (using phenotypic data in analyses)
Guilherme Rosa>
(608) 265-8617

Research Interests: The interface between statistical/theoretical and molecular genetics, focusing on applications to animal models in domestic/managed and natural populations based on observed data and genomic prediction.
Emeritus: Dave Thomas - Animal Breeding (sheep, dairy sheep, small ruminants)
DAve Thomas
Research Interests: My research team and I have been involved in many areas in sheep breeding and management. In recent years, we have developed a research program in dairy sheep production at the Spooner Agricultural Research Station that serves this small but growing industry in North America.


Thomas Crenshaw - Nutrition (swine, bone growth)
Tom Crenshaw
(608) 263-4423

Research Interests: Dietary manipulation and cellular regulation of endochondral ossification, renal and skeletal compensation to dietary cation-anion balance; optimization of dietary lysine utilization; baby pig growth and survival
Dhanu Shanmuganayagam - Nutrition (cardiovascular physiology, gut physiology & health, swine biomedical models)
Dan Schaefer
(608) 890-1332

Research Interests:
My research program is focused on the development and utilization of novel swine models of human disease for elucidating mechanisms and discovering targets for development of diagnostic and therapeutic technologies. The genetic proximity of swine to humans and the overwhelming similarities in anatomy, physiology, and nutrition make swine the ideal model for preclinical studies of the interaction between genetics and nutrition as it relates to diseases. I believe that the use of such highly translational models accelerate the rate at which discoveries can be developed into applications and technologies that benefit human and animal health.
Dan Schaefer - Nutrition (beef, grazing systems)
Dan Schaefer>
(608) 263-4513

Research Interests:
• To evaluate factors that increase beef production in grazing systems
• To examine strategies for feedlot manageement that enhance animal health, production efficiency and food safety
Jess Reed - Nutrition (phytochemistry, gut physiology & health)
Jess Reed
(608) 263-4310

Research Interests: Research on the phytochemistry of food and livestock feeds and their effects on animal and human health and nutrition. The role of mucosal immunology in the interaction of nutrition and health.

Meat Science

Jim Claus - Meat Science (quality)
JIm Claus
(608) 262-0875

Research Interests: My research interests are in four distinct areas of muscle food:
1. Improvement in meat tenderness
2. Muscle pigment chemistry as related to meat color
3. Technology for the development of low-fat processed meats
4. Textural defects in sectioned and formed poultry products
Mark Richards - Meat Science (lipid oxidation, poultry, fish)
Mark Richards
Research Interests: The role of lipid oxidation in the quality of muscle foods. Understanding the mechanisms of lipid oxidation in food systems is crucial for developing novel strategies for inhibition of lipid oxidation. We are interested in the role that blood components such as hemoglobins and myoglobins play in mediating lipid oxidation.
Jeff Sindelar - Meat Science, Extension (processed meats development, HACCP)
Jeff Sindelar>
(608) 262-0555

Research Interests: Quality, safety, and sensory characteristics of processed meats. Use of non-meat ingredients for funcionality - ie inhibition of pathogenic bacteria, improved sensory characteristics
Extension Interests: Providing assistance to meat processors in the areas of product development, problem solving and regulatory compliance; Serving as a liaison between academia, government and the meat industry;

Microscopy, Animal Health & Reproductive Physiology

Ralph Albrecht - Microscopy (nanoparticles)
(608) 263-3952

rough-surfaced, umbonate 18 nm cPd particles

Research Interests: Development of colloidal nano-particles of differing composition and shape for correlative and high resolution labeling in light microscopy, and electron microscopy as well as CT and MR applications. Current studies also involve the synthesis of inductively heated magnetite/gold (core/shell) nano-particles for targeted in vitro and in vivo cell killing of cells (such as tumor or auto-reactive cells) or for selective cell permeation of labeled cells. Other interests include receptor-ligand-cytoskeleton interactions; microvasculature development, biomaterial compatibility, and immunotoxicology.

John Parrish - Reproductive Physiology (male, fertility, large animal)
John Parrish
(608) 263-4324

Research Interests: Our research interests focus on male reproduction, in specific, factors effecting male fertility. We are currently studying the effects of climate change on spermatogenesis. Using the boar and bull as models, we are exploring cellular and molecular effects of heat stress.
