Biography
Born and raised in beautiful Kansas City, I earned a B.A. in biology at the University of Missouri - Kansas City in 2007 and a Ph.D. in Toxicology at the University of Kansas Medical Center in 2013.  While an undergraduate, I worked for two years as a lab technician. Through that experience, I developed an interest in research and was inspired to pursue graduate school. For my dissertation work, I joined the lab of Dr. Hartmut Jaeschke and investigated issues of clinical relevance with regard to the mechanisms of APAP hepatotoxicity. In particular, I became strongly interested in the development and improvement of blood biomarkers for APAP hepatotoxicity. As a post-doc, I am continuing this work and expanding to study other drugs and environmental toxins.


Research Interests
Acetaminophen (APAP) is one of the most used drugs in the world, but overdose of APAP is the chief cause of acute liver failure in many Western countries. Working in the Jaeschke lab, I am involved in studies designed to lead us to a better understanding of the physiological mechanisms of APAP hepatotoxicity. Although much progress has been made in this field using rodent models, the relevance of these data to humans is still not certain. To rectify this, we are taking a translational approach, incorporating human samples and improved in vitro human hepatocyte models into our other work. We are also investigating the mechanisms of microcystin hepatotoxicity. In addition to standard laboratory techniques (histology, enzyme kinetics, PCR, western blotting), my work has grown (and continues to grow) to include a number of fascinating analytical and molecular tools.
