Research Experience

• Investigated the role of turbulence and particle agglomeration in the transport of polynuclear aromatic hydrocarbons in estuarine environments.
• Investigated the role of biological and physical/chemical particle removal mechanisms in slow sand filters. Determined that previously removed particles increase the attachment efficiency of subsequently applied particles.
• Initiated and conducted research to identify slow sand filter particle removal mechanisms. Determined that protozoans are responsible for significant bacteria removal in slow sand filters.
• Co-authored proposal on the role of organic carbon in slow sand filters that was funded by the U.S. Environmental Protection Agency.

Experimental Apparatus Design and Fabrication

• Designed and fabricated a novel differential turbulence column with 5 independent turbulence generating grids, an acoustic Doppler velocimeter and a conductivity microprobe for analysis of turbulence and salinity profiles.
• Designed and fabricated filter apparatus with provision for depth sampling.
