Current Research Interests

Drinking Water Treatment

Chemical disinfection processes; especially their kinetics against microorganisms and methods for design and scaleup
Inactivation of emerging pathogens by disinfectants
Novel kinetic models for disinfection processes and process control
Use of computational fluid dynamics for process modeling

Assessment of risks from exposures to deliberately released agents (e.g., anthrax)
Engineering analysis and optimization of chemical decontamination schemes
Appropriate sensing equipment for water utilities to monitor deliberate contamination

Microbiological risks associated with diverse exposures
- pathogens in drinking water and recreational waters
- pathogens in biosolids (sludges)
- pathogens in food (including E. coli O157:H7, Campylobacteria and Listeria)
- risks from personal household exposures, and prevention using anti-microbial agents
