About

I’ve always been fascinated by the biology around me. From snakes, insects, and frogs to moss, trees and flowers I spent my youth crawling the meadows and ponds of suburban Michigan and my summers in the Wasatch and Uinta mountains looking for new organisms to discover and study. When I got to the University of Utah I had the opportunity to delve deeper into biology and fell in love with plants. Between combing the deserts and mountains looking for new species of wildflowers and putting hours in the lab and field studying tree water relations I spent my undergrad years deeply involved with our native flora. I then went on to pursue a PhD in plant ecophysiology under the advisement of John Sperry at the U. My research interests have focused on tree responses to drought stress and the development of models to predict forest productivity and mortality risk. After my PhD I had postdoctoral appointments at the University of Alberta and the University of Georgia before joining the Biology Department here at Snow where I get the incredible opportunity to share what I know about biology with our fantastic students.

Research

  • My research centers around the central question “how will plants respond to climate change”, focusing on how vascular plants will respond to increasing drought, and how to predict mortality risk and recovery following drought stress.
  • I have 11 years of experience in fieldwork, project design, and data management both as part of large and small teams, and as a manager of junior researchers.
  • Products of my research efforts include publications in peer reviewed journals, scientific presentations, and novel modeling tools and methodologies.
