Dr. Humes has had the good fortune of having a diverse career both within and outside of academia. She has worked for the NASA Jet Propulsion Laboratory on space-based geodesy and spacecraft tracking, held a graduate fellowship at NASA Goddard Space Flight Center in remote sensing, and served as a Postdoctral Research Assistant at the USDA/Agricultural Research Service Hydrology Lab in Beltsville, MD. Her early research involved field work in remote sensing of land surface characteristics that control land/atmosphere interactions. In this work, she participated in numerous interdisciplinary field campaigns in Arizona, New Mexico, Oklahoma, France and Niger.
In recent years, she has been privileged to work with many outstanding graduate students in the applications of remote sensing data (both lidar and multispectral data types) in a variety of topics – including characteristics of conifer forests, monitoring snowpack, and an emerging program in planning for renewable energy from wood based biofuels. She is interested in outreach in climate, energy and geographic education. She has mentored numerous undergraduate and graduate students in research and was awarded the 2011 Don Crawford award (UI-wide award) in Outstanding Graduate Student Mentoring. She became Chair of the Dept of Geography in July 2011.
