Curriculum Vitae

Education

• Ph.D., Civil and Environmental Engineering, Massachusetts Institute of Technology
• B.S. Civil and Environmental Engineering, Cornell University

Research and Scholarship

The ultimate goal of Dr. Jellison’s research is the prevention of waterborne disease. She strives to achieve this goal from two different, but complementary, approaches: (i) the protection of drinking water sources from contamination with waterborne pathogens and (ii) the design/optimization of household water treatment technologies appropriate for use in developing countries.

Dr. Jellison’s research team focuses on environmental sources, fate, and transport of Cryptosporidium.  This protozoan parasite is responsible for waterborne outbreaks of cryptosporidiosis, a self-limiting illness in otherwise healthy people that can be prolonged and life-threatening in the immunocompromised population. The team's research in the area of household drinking water treatment focuses on simple technologies like biosand filtration, ceramic pot filtration, and chlorination. She is working to optimize such technologies and standardize their operating procedures to make them more effective, affordable, and available to a larger global population.

Dr. Jellison is recipient of a CAREER Award from the National Science Foundation, and her research is also supported by U.S. Environmental Protection Agency, the Lindbergh Foundation, Pennsylvania State University, the Pennsylvania Department of Community and Economic Development, and the Philadelphia Water Department.

Teaching and Service

Dr. Jellison teaches Introduction to Environmental Engineering, Enviro-Geo-Hydraulics Lab, Environmental Case Studies, and Water and Wastewater Treatment Facilities.

Dr. Jellison will assume the directorship of Lehigh’s NSF-ADVANCE  grant in June 2013.  She is a member of the American Society for Microbiology, the American Water Works Association, the American Chemical Society, the American Association for the Advancement of Science, Sigma Xi, and the Association of Environmental Engineering and Science Professors. She is also a co-adviser of Lehigh’s Engineers Without Borders Program.
