Growing up in western Washington, I always wanted to be a teacher. I eventually decided I wanted to teach high school biology and coach sports. It was not until my junior year of college that I discovered my passion for research and decided to earn a PhD. Now, I fulfill my passion for teaching and research as a faculty member in the College of Pharmacy and Pharmaceutical Sciences. I teach in the Principles of Pharmacology and Fundamental of Toxicology course in the Pharmaceutical Sciences and Molecular Medicine PhD program and in the Integrated Pharmacology II course in the Doctor of Pharmacy (PharmD) program. Mentoring PhD and PharmD students in my research lab is a highlight of my work.
My research group focuses on understanding inter-individual variability in xenobiotic exposures and toxicities—meaning, we want to know what makes two people different in terms of how they handle and react to toxins and drugs. Some of the variables we research that make two people different include genetics, diseases, and dietary supplement use. We study each of these variables both alone and in combination with each other. We have particular expertise in drug transporters and liver diseases, such as nonalcoholic fatty liver disease. Our research can be summarized in one major goal: improve precision medicine by accounting for the factors in inter-individual variability.
In my spare time I like to…
I enjoy spending time with my family hiking, running, biking, boating, and camping.
04/01/2017 – 03/31/2021 (NCE)
Title: Microcystin-LR toxicity in nonalcoholic steatohepatitis
Goal: Investigate how the liver disease nonalcoholic steatohepatitis affects the toxicity of microcystin-LR (an environmental toxin from blue-green algae) and how the toxin is removed from the body.
08/01/2020 – 07/31/2022
Title: Enteric and hepatic transporter mechanisms for pharmacokinetic natural product-drug interactions.
Goal: Determine how the natural product-drug interactions between goldenseal-metformin and green tea-raloxifene are affecting how the intestine and liver handle drugs in the body.
09/23/2020 – 09/22/2021
Title: Risk of xenobiotic-drug interactions in chronic disease
Goal: Determine the individual and combined effects of the natural product silymarin (often marketed for liver disease) and the liver disease nonalcoholic steatohepatitis (NASH) on how the liver removes drugs from the body.
1/19/2020 – 10/31/2025
Title: Mechanisms of microcystin-induced hepatocellular carcinoma in nonalcoholic Steatohepatitis
Goal: Investigate how microcystin-LR causes liver cancer in nonalcoholic steatohepatitis (NASH).
