Teaching Philosophy

My goal as an educator and mentor is to provide the knowledge to transform students into independent and analytical thinkers and broadly prepare students for careers in science. I provide skills in analytical thinking by offering opportunities to write critically, communicate and debate scientific issues with their peers and design, conduct and analyze scientific research. Moreover, my experiences conducting research in academic, industrial and governmental settings will allow me to mentor students interested in careers in a variety of scientific disciplines. I believe that my teaching background, commitment to students and experience in diverse scientific career paths will contribute to the outstanding education, research opportunities and mentoring students expect from Boise State.




Animals are faced with the daily challenge of processing large quantities of toxins present in their environment. However, the way animals respond and deal with these toxins is poorly understood. I am interested in understanding the behavioral and physiological consequences of exposure to plant secondary metabolites (i.e. toxins) and the mechanisms that herbivores employ to mitigate the negative effects of exposure to plant toxins. My research focuses on two general areas related to plant-herbivore interactions employing a combination of laboratory and field-based approaches:

  1. Evolutionary diversity of plant-animal chemical interactions: The main aim of this research is to evaluate the evolutionary diversity of plant secondary metabolites (PSMs) and the evolutionary diversity of receptor targets and mechanisms of absorption, distribution, metabolism, excretion and toxicity (ADMET) of PSMs in animals. Specific study systems include: sage-grouse in Idaho, Oregon and Wyoming; pygmy rabbits and Piute ground squirrels in Idaho; snowshoe hares in Alaska; moose in Isle Royale. These projects may reveal the co-evolutionary interactions between plants and animals, but can also be applied to conservation efforts to manage the species involved in these interactions.  For example,  in a collaboration with USGS, University of Florida, University of Idaho and Washington State University we use unmanned aerial vehicles to map attributes of quality habitats for pygmy rabbits (PosterUAV video). These projects are supported by the National Science Foundation, Bureau of Land Management, Idaho Office of Species Conservation, Idaho Department of Fish and Game, Wyoming Game and Fish, US Geological Survey, US Forest Service.

  2. Pharm-Ecology: An ecological approach to natural product drug discovery: The main aim of this research is to utilize the technology and insight of two disparate, yet highly complementary fields: ecology (both physiological and chemical) and pharmacology (science of drugs, including their composition, uses, and effects) to discover the biological activity of natural products in the areas of infectious disease and cancer. Insight from the interactions between PSMs and the physiological and behavioral responses of herbivores to these compounds will expedite drug discovery and reveal the mechanisms by which bioactive molecules are therapeutic or toxic.  For example, we have worked with high school students to identify the bioactive properties of sagebrush (  This research is supported by the National Institutes of Health (INBRE), the National Science Foundation, Fulbright and is a collaboration with the College of Idaho, Hedmark University of Applied Sciences, Icelandic Institute of Natural History and Grimsö Wildlife Research Station at Swedish University of Agricultural Sciences.

Students and teachers from IdahoWatch 2014

I recently developed IdahoWatch, a new STEM Service-Learning model, where graduate and undergraduate students take K-12 teachers into the field to learn about local research. The teachers participated in citizen science by recording behavior of Piute ground squirrels, greater sage-grouse and pygmy rabbits, and measuring habitat quality and use of habitats by these native species. They collected data and samples in the field that they use in lessons plans to teach their students what, how ,and why researchers study in this local ecosystem. (Article)
