Associate Professor, Food Science
RESEARCH INTERESTS
Dr. Hellberg’s research is focused on food safety and mislabeling. On the food safety side, she investigates the effects of climate change on food safety, specifically with regard to food microbiology, and she works on the development of molecular methods for the identification and differentiation of foodborne pathogens. On the food mislabeling side, she develops and applies molecular methods to identify instances of species substitution or misbranding in a variety of food items. Specific projects underway include modeling the relationship between climatic factors in Orange County and human illness from Salmonella, examination of Listeria isolates for the presence of a gene important in virulence, investigation of game meat mislabeling, and development of a primer set to perform DNA barcoding on canned fish.

Jerry L. LaRue, Ph.D.
Assistant Professor, Chemistry
RESEARCH INTERESTS
Catalysts are the unsung heroes of chemistry: Widely used in industry, they speed up chemical reactions by making the reactions much more efficient. Many important reactions related to global issues, such as climate change and carbon-neutral fuel production, take place on the surfaces of metal catalysts. Today we know very little about how these reactions proceed. Dr. LaRue’s research interests are aimed at understanding the most fundamental aspects of the processes that occur during chemical reactions on these catalytic surfaces. His current projects involve using ultrafast optical techniques, x-ray spectroscopy, and Raman spectroscopy to probe the elementary steps of chemical reactions with the goal of learning how to create more efficient catalysts for the challenges of tomorrow.

Cedric P. Owens, Ph.D.
Assistant Professor of Biochemistry
RESEARCH INTERESTS
The Owens laboratory is very interdisciplinary and conducts research at the interface of inorganic chemistry, biochemistry, and molecular biology. We currently focus on two research areas: (1) We are investigating regulation of the metalloenzyme nitrogenase in nitrogen-fixing bacteria. Nitrogenase contains several unique metal cofactors and is responsible for the biological conversion of inert nitrogen gas into ammonia, a critical nitrogen source for plants. By deepening our understanding of nitrogenase regulation, we aim to uncover ways of increasing biological ammonia production for agricultural applications. (2) In a separate project, we are studying how bacteria acquire iron with the aim of exploiting bacterial iron uptake for antibiotic development.

Melissa Rowland-Goldsmith, Ph.D.
Associate Professor, Molecular Biology
RESEARCH INTERESTS
Dr. Rowland-Goldsmith’s research interests center around studying human pancreatic cancer which is the 4th leading cause of cancer related death in the United States. The ability of pomegranate juice extract (PJE) to stimulate apoptosis (programmed cell death) and inhibit cancer cell invasion in several cancer types has been attributed to its high polyphenol content. Caffeine has also been shown to induce apoptosis in several cell types. Specific projects under investigation include the study of natural products (PJE and caffeine) to reduce pancreatic cancer cell proliferation and migration as well as promoting cell adhesion.
