Research Interest
Our research focuses on problem alcoholic fermentations and spoilage microorganisms of concern to winemakers. Problem alcoholic fermentations are those where utilization of fermentable sugars by wine yeast is slow and/or undesirable off-odors and flavors are produced. While it is well documented that a lack of available nitrogen in musts can be a problem in Washington state and elsewhere, little is known regarding the role of other nutrients such as vitamins. Our laboratory was first to document interrelationships between certain nutrients and available nitrogen that affect yeast growth and H2S production. We are continuing to study key nutrients in an effort to develop preventative strategies of management such reformulation of nutrient additives and new ways to prepare cultures. Spoilage issues of concern to Washington State include Lactobacillus, Pediococcus), and more recently, Brettanomyces. Our laboratory yielded the first published report that Lactobacillus can inhibit wine yeast and therefore slow alcoholic fermentations. The bacterium was later identified as a novel species of Lactobacillus and named Lactobacillus kunkeei after Dr. Ralph E. Kunkee (UC Davis). Later, another novel species was isolated and named Lactobacillus nagelii in honor of Dr. Charles W. Nagel, (Washington State University). More recently, our laboratory has determined that Brettanomyces appears to enter a “viable-but-not-culturable” state as well as studying novel methods for microbial control.Courses Currently Teaching

Research Interest
My laboratory works on grape (Vitis vinifera) and wine composition. We primarily focus on phenolic compounds in grapes and wine and their biochemical and chemical changes during ripening, winemaking and aging. Phenolic compounds are important to wine, for their influence on sensorial aspects including bitterness, astringency, color, and aroma. Phenolics are also important for their influence on the preservation of wine and health related aspects. The laboratory is located at the Chateau Ste. Michelle Washington State University Wine Science Center located at the Tri-Cities Campus in Richland Washington. We are fully committed to collaborative style research and make wines for vineyard and winery projects. We also collaborate with industry on projects that have included commercial scale winemaking, and vineyard trials. The topics studied tend to follow industry based problem solving and have varied. Topics studied include: extended maceration, ethanol concentration, cofermentation, saignée, exogenous tannin addition, rootstocks, deficit irrigation and fruit maturity. We also do more basic research including method development and natural product purification. The laboratory is outfitted for preparative (Flash Chromatography, Prep-HPLC, Nano-Spray Dryer) and analytical (HPLC-MS-MS, HPLC-QTOF, UV-vis, NIR spectroscopy) chemistry.Education

Research Interests:
Visit the website for additional information about my research and lab. My applied food microbiology research program is focused on food safety and dairy microbiology. I have one biosafety level 2 (BSL-2) Dairy Microbiology Laboratory and one BSL-1 Food Processing Laboratory. The research conducted in my laboratories focus on making food safe and healthy, and hence involves working with foodborne pathogens as well as probiotics. My research group works on fermented dairy products, improving probiotic longevity, utilizing whey, microbiological safety of dairy products (especially dairy powders), and removing biofilms from dairy processing surfaces. We conduct both in-lab and in-plant validations of food processing and antimicrobial interventions to control foodborne pathogens in dairy, beef, poultry, bakery, and pet foods. My research group has significant experience conducting thermal inactivation kinetic (D- and z-values) studies of various foodborne pathogens in different food matrices. My research group is also developing rapid identification techniques for pathogens in food and food processing environments using hyperspectral imaging. We are additionally working on studying the application of nanobubble technology to improve food safety and quality.Courses Taught:

Research Interest
The overall objective of my research and graduate education program is to understand the theoretical basis underpinning the sensory perception (aural, oral, and tactile) of foods and wines and to correlate these psychophysical attributes with quantifiable characteristics. This research is focused in three major areas:- The influence of agronomic and environmental conditions on the chemical and sensory profiles of foods and wines
- The application of innovative analytical and sensory techniques to increase understanding of fundamental physical and chemical properties of food and wine quality
- The enhancement of food quality through studies of consumer perception.
Courses Taught
- FS 422/522: Sensory Evaluation of Food and Wine (Spring semester) This course provides an introduction to the theory, principles and applications of sensory evaluation techniques for the evaluation of appearance, aroma, flavor and texture of foods and wine. Students will learn the basic psychological and physiological processes underlying sensory analysis, sensory testing methodologies and the basic principles of flavor perception and chemistry.
- FS 423: Sensory Evaluation of Food and Wine Laboratory (Spring semester) Practical application of FS 422 including theory, principles and application of sensory evaluation techniques for appearance, aroma, flavor and texture of foods and wine.
- FS 461: Food Chemistry Laboratory (Fall semester). Experiments related to the properties, reactions and interactions of chemical components of foods.

Food Microbiology and Nutrigenomics Laboratory
*Currently accepting graduate student applications.Research Interests
Our research interests center on microbiological food safety and effects of dietary bioactive compounds on gut microbiota and chronic diseases. For the nutrigenomic study, we are studying impacts of diets on intestinal epithelial differentiation, gut microbiome, and metabolic diseases. We use both in vivo mice models and in vitro cell culture to examine the intricate interaction among nutrients, microorganisms, and gut epithelial health. For food safety research, we are seeking novel strategies to inactivate, intervene and detect foodborne pathogens in foods and food production environments, and further explore their applications in the food industries; we are also exploring behaviors of foodborne pathogens and their interactions with the background microbiome. We use metagenomics, molecular and traditional microbiological techniques for our studies.Selected publications
