Drexel University Internships/Graduate Opportunities

1. Documenting the Effects of Urban Sprawl on a Model Watershed Near Philadelphia, Pennsylvania. Interdiscipliary evaluation of surface/subsurface contaminant pathways and effects on stream biota, coupled with evaluation of the political forces that have influenced the land use history of the watershed. NSF/EPA/USDA Water And Watersheds; PI: C. Welty; Co-PIs: S. Kilham, A. Packman, R. Brulle. (New March 1, 2000). 4 PhD students needed with interest in one of the following areas: ecology, surface water hydrology, groundwater hydrology, environmental policy. The hydrology students should have a quantitative background.
2. Modelling Virus Transport in Aquifers. Ongoing effort to evaluate the interaction between aquifer heterogeneity and colloid/virus transport. NSF, Hydrologic Science. PI: C. Welty; co-PI: R.W. Harvey (USGS). A PhD student or post-doc with numerical modeling background (i.e., knowing how to code) is needed.
3. Evaluation of Density-Coupled Transport in Heterogeneous Aquifers. Ongoing effort - physical experiments and numerical modeling. NSF, Hydrologic Science and International Activities. PI: C. Welty. co-PI: T. Illangasekare. One MS-level student needed, primarily to work on physical experiments.
4. Disinfection processes for drinking water. Evaluation of inactivation kinetics for protozoans and bacterial pathogens using chemical disinfection processes. Students interested in working on mathematical analysis and modelling of disinfection systems are particularly needed. AWWARF. PI: C.N. Haas.
5. Microbiological risk assessment. Development of models for the transmission of illness via hand-to-mouth transfer of microorganisms. This effort may also extend into population level modeling. Funding from a number of consumer products companies. PI: C.N. Haas.
