Greetings! I am happy and proud to be on the FHSU faculty and to serve as chair of the Department of Geosciences. I teach mainly classes concerned with the physical world and how humans interact with their environment, and sharing my fascination with students is a great joy. As you will read below, my research is exciting and addresses important questions, and I involve students in every aspect of my work. If you are thinking about attending FHSU, I'm sure you will have a great experience, and please don't hesitate to contact me for information or advice.

The Earth’s polar ice caps, and particularly sea ice, are decreasing rapidly as greenhouse gas amounts increase in the atmosphere. Because the polar caps are located where the climate is very harsh, the major way we can measure changes in polar ice is through images from satellites. I have been working for many years, supported by the National Aeronautics and Space Administration (NASA) to use visible-band, infrared, microwave, and radar instruments to map the polar sea ice and understand how it moves and changes. My latest work involves a satellite called ICESat, which uses a laser beam to measure the thickness of the ice, to study how ocean waves and sea ice interact. Many undergraduate and graduate students have had the opportunity to participate in this NASA-sponsored research, both in setting scientific goals and data collection and analysis.
Western Kansas is in a rather special location, where air masses from several different directions come together and interact to produce extreme weather conditions and some dangerous natural hazards such as tornadoes, hail, floods, and drought. My research goal is to understand the factors that influence the climate of Western Kansas, including the frequency of severe weather events. This work has yielded important results - for example the single greatest influence on year-to-year precipitation in Western Kansas is the El Nino cycle. Another significant observation is that the record of tornado reports is subject to large uncertainties due to observational effects that need to be examined closely before any conclusions can be drawn about long-term changes in severe weather frequency. Students have been heavily involved in this work, ranging from collecting accounts of severe weather events to performing statistical analysis of weather data and records. The Department of Geosciences maintains two weather stations, one on campus and one on the University Farm, both of which were built and are maintained by student assistants.
A relatively new area of research for me and my students is the use of small and medium-sized rockets for capturing imagery of the Earth’s surface. For example, the picture below was taken by a digital camera aboard a small rocket and shows a portion of the FHSU campus from an altitude of about 450 feet. Work is underway to produce a rocket system that can reach altitudes of half a mile with high-resolution cameras.

My research interests lie in two primary areas, remote sensing and climatology, focusing on the Arctic and the Central High Plains of the United States. Within remote sensing, most of my work involves the use of radar imagery in combination with data from infrared and visible sensors. One recently completed project, funded by the National Aeronautics and Space Administration, used data from the Canadian RADARSAT satellite to constrain a numerical ice and ocean model of Baffin Bay. An ongoing project is using ice-penetrating radar to measure the thicknesses of Alaskan glaciers. Another is evaluating the use of radar images to reveal surface and subsurface characteristics in western Kansas. Another current project uses data from a new NASA microwave sensor (the AMSR) to study sea ice near Barrow, Alaska. My work in climatology has attempted to determine the variability of temperature and precipitation in western Kansas over the last 100 years and to explain the variability as a function of forcing variables such as El Nino, global climate change, and changes in solar output.
