Title: Assistant Professor of Toxicology and Nutrition
Biography of Investigator:
During my service with the U.S. Peace Corps in Nepal, I conducted several trainings in conjunction with women’s health initiatives geared towards improving hygiene and nutrition for disease prevention and reducing environmental exposures. I have also conducted ecological and human health risk assessments as well as drafted/audited EPA Toxicological Profile reports while working at Tetra Tech NUS and consulting for Oak Ridge Institute for Science and Engineering (ORISE). I soon discovered that my strengths and passion to address major public health issues, specifically those regarding immunity and cancer were through hypothesis-driven research, and thus sought out postdoctoral training with a NCI Cancer Control and Prevention fellowship to translate laboratory findings of “reduced humoral immune responses by NSAIDs” to vaccine trials in the clinic.
This past year, while with the Crops for Health program at CSU, I have been studying the effects of food components on cellular metabolism, and with the goal of improving the interface between plant and biomedical scientists to improve the investigation of health promoting characteristics of foods available to humans and animals in the marketplace. This transdisciplinary initiative was to develop novel, sustainable breeding strategies that incorporate health traits, but are NOT related to genetic modification of foods. Rice feeds half of humanity, and the bran fraction is a rich source of chemicals and nutrients that is often not consumed. Our lab is now examining bioactive rice bran components for modulation of immunity and tumor metabolism. Alternative medicine practices with plant -derived compounds have been widely available and consumed in the western world, however limited evidence-based research exists for their use in conjunction with standard of care cancer treatments.
Cancer patients are among the largest consumers of natural product supplements, and my laboratory will utilize the canine cancer model to investigate clinically relevant drug-herb interactions. This program of research seeks to determine the safety and efficacy of herbal supplement use during chemotherapy, and thus contribute to evidence-based guidelines regarding complementary and alternative medicine strategies for cancer care in animals and humans.
