Brief Faculty Profiles

Raymond J. Carroll, Ph.D. Top of Page

Raymond J. Carroll is the principal investigator of the training grant, Professor of Statistics, Nutrition and Toxicology, Director of the Center for Statistical Bioinformatics, and Deputy Director of the Institute for Applied Mathematics and Computational Science. His main interests involving modeling complex nutrition and genomics data arising from the laboratories of the nutrition mentors in the training grant.

Nancy Turner, Ph.D. Top of Page

Dr. Turner is an associate professor in the Department of Nutrition & Food Science and serves as Associate Director for the training program. The overall goal of her research is to identify bioactive compounds in the diet that can suppress inflammatory bowel disease and colon cancer incidence. She uses animal disease models to study the effect of these compounds on maintenance of redox balance; regulation of cell proliferation, differentiation and apoptosis; DNA damage and repair; regulation of gene transcription and translation; and transmission of signals through a variety of signaling cascades. Techniques used include immunohistochemistry, immunoblotting, gas chromatography, real-time PCR, microarray analysis, and enzyme kinetic assays to ascertain the mechanisms whereby bioactive compounds influence disease development and progression.

Robert Chapkin, Ph.D. Top of Page

Dr. Chapkin is established in the areas of transmembrane signaling, protein kinase C signal transduction, and cell/molecular biology techniques. His research has been directed towards the modification of those processes by nutritional and pharmacological intervention. His work is supported by grants primarily from the National Cancer institute. He is the co-director of the Texas A&M genomics facility.

Rosemary Walzem, Ph.D. Top of Page

Dr. Walzem's research program focuses primarily on lipoprotein biology. Lipoprotein metabolism is exquisitely responsive to diet, and possible relationships between diet-induced alterations in lipoprotein metabolism and carcinogenesis are largely uninvestigated. She joined Texas A&M University in 1999 as an Associate Professor. She is on the editorial board of Poultry Science and was awarded the Amorin Prize in 1995 for her contributions to the area of Wine and Health.

Clint Allred, Ph.D. Top of Page

Clint Allred, Ph.D. is Assistant Professor in the Department of Nutrition and Food Science at Texas A&M University. Dr. Allred received his B.S. in Animal Science from the University of Georgia in 1997. He completed his Ph.D. in nutrition at the University of Illinois in 2002. He then served as a postdoctoral fellow in the department of pharmacology at the University of Kentucky College of Medicine until August of 2006.

Joseph Sturino, Ph.D. Top of Page

Joseph Sturino, Ph.D. is Assistant Professor in the Department of Nutrition and Food Science. Dr. Sturino's laboratory uses functional genomics (e.g., comparative genomics, targeted gene knockouts, Biolog phenotype microarrays, and oligonucleotide microarrays) to dissect the role of individual genes in coordinating interaction between gastrointestinal microorganisms (both pathogenic and probiotic) and their human host.

Nancy Amato Top of Page

Nancy Amato is Professor of Computer Science and Engineering. Her lab is interested in developing algorithmic solutions for problems in areas such as computational biology (e.g., protein folding and drug design), motion planning (e.g., animation and robotics), computational geometry, parallel and distributed computing (e.g., parallel algorithms, performance modeling & prediction), and computational science (e.g., physics, geosciences, neuroscience).


Laurie Davidson Top of Page

Laurie Davidson’s research interests include non-invasive detection of colon cancer markers, modulation of colonic cytokinetics by diet, use of colonic cell lines and experimental animals to study cytokinetics/colon cancer. She also studies protein kinase C modulation of colon carcinogenesis; effects of diet and carcinogen on colonic ras signaling.
