Kristen Jellison
Civil

CEE faculty page
Kristen Jellison received her B.S. in Civil and Environmental Engineering from Cornell University in 1997 and her Ph.D. in Civil and Environmental Engineering from MIT in 2003. She joined the Lehigh faculty in the department of Civil and Environmental Engineering in Fall 2003. Jellison’s research interests are rooted in the prevention of waterborne disease through both improved water treatment and a thorough understanding of the environmental sources, fate, and transport of microbial pathogens. Currently, work in Jellison’s laboratory focuses on the protozoan parasite Cryptosporidium parvum, an organism which causes gastrointestinal disease that is self-limiting in otherwise healthy individuals but can be fatal for people with compromised immune systems. Ongoing research projects include:
- A collaboration with the Philadelphia Water Department to identify sources, species, and infectivity status of Cryptosporidium spp. in the city’s raw drinking water supply using phylogenetic analysis of the 18S rRNA gene. These data will be used by the city to develop watershed management programs to protect drinking water supplies from Cryptosporidium contamination.
- A study of the efficacy of various portable water disinfection systems (such as those used by backpackers) in inactivating C. parvum oocysts in surface waters under varying conditions of temperature, pH, turbidity, and exposure to sunlight.
- A collaboration with Bruce Hargreaves and Craig Williamson to study the impact of various watershed characteristics (amount of solar UV radiation, quality and quantity of dissolved organic carbon, presence of protozoan grazers) on C. parvum oocyst viability and infectivity.
- An investigation of the impact of biofilms on C. parvum oocyst fate and transport in both open channel and porous media flow.
Jellison teaches CEE/EES 379: Environmental Case Studies, CEE 376/476: Environmental Biotechnology, CEE 275: Environmental, Geotechnics, and Hydraulics Laboratory, and Engineering 5: Introduction to Engineering Practice.
