Research Experience

Experience was gained in developing and deploying a video based system for observing bubble plumes with Dr. Peter Bowyer as a postdoctoral researcher at the National University of Ireland, Galway. Responsibilities included circuit and physical design, purchasing, developing computer algorithms, managing technical staff, and trouble shooting. Experience in image processing and analysis of bubble plumes was also gained. During this time period, further modeling experience was gained as a result of additional model development in collaboration with Dr. William E. Asher.

Experience was gained in theoretical and computational modeling of bubble mediated air-sea gas transfer gained under research conducted by Dr. William E. Asher for U. S. Department of Energy, Office of Health and Environmental Research. Laboratory experience was gained in measuring air-sea gas transfer including gas chromatography. The primary focus was the development a computer model for predicting the bubble component of air-sea gas transfer. The model has been validated by comparison of theoretical predictions with experimental measurements. Model development continued at Georgia Institute of Technology under the guidance of Dr. Bob Roper and Dr. William E. Asher.

Experience was gained in molecular ion spectroscopy working under Dr. Fred Eisle, while a graduate student at Georgia Institute of Technology, prior to beginning work with Dr. William E. Asher. Research responsibilities primarily involved measurements and technical support.

At the University of Michigan, plasma physics in the upper atmosphere and magnetosphere was studied, while a graduate student. The study of plasma physics was continued at Georgia Institute of Technology through the completion of a minor in fusion physics.

Experience was gained in cryogenics under Dr. Chaz Archie in the Low Temperature Physics Laboratory, while an undergraduate senior at the State University of New York, Stony Brook.
