Curriculum Vitae
My curriculum vitae, including publications, is available in both Word and PDF formats.

Cumulus entrainment:
As cumulus clouds grow, they entrain pockets of dry air.  The rate of entrainment of air affects the thermodynamic and radiative properties of the cloud, which in turn affects the environment.  Currently, cumulus entrainment observations come from in situ probes mounted on research aircraft.  I am developing a techique to retrieve cumulus entrainment rate from ground-based remote sensing instrumentation.  The product wil be used to assess the validity of entrainment parameterizations as well as provide a dataset to investigate the climatology of entrainment.

Severe storm environments:
The high temporal resolution of ground-based profiling instruments provides a look at the evolution of severe weather environments with much greater detail than possible with in situ observations. By evaluating the change in thermodynamic and kinematic indices as observed by these instruments, new insights into the development of storm-producting environments can be found.

Large lecture courses remain one of the most common formats for instruction in introductory meteorology, but the impersonal nature of these courses makes it difficult for students who learn better in more interactive environments.  In order to better serve these students, a series of online applets that illustrate a number of different concepts in the course.  My research involves quantifying the impact of these applets on student learning over the duration of the course.
