Research Interests: Biological Sensors
This project involves the development of an optical sensor capable of the identification and partial quantification of pathogen indicators to include Escherichia Coli, Total Coliforms and/or enterococci in fresh and marine waters.  The biosensor is capable of continuous, long-term in situ monitoring of recreational and source water.  It can be wirelessly connected to a central monitoring station in order to provide early warning of the presence or absence of dangerous pathogens.

Research Interests: Chemical Sensors
Low cost, real time, down hole sensing of chlorinated solvents in groundwater using low cost electrochemical measurement.
The presence of chlorinated solvents such as 1,1,1-trichloroethane, 1,1-dichloroethane, trichloroethene (TCE), and tetrachloroethene in groundwater results in significant costs associated with site characterization and plume monitoring.  A low cost sensing system that measures the concentration of these materials in the subsurface in real time would provide a means of reducing costs associated with plume definition and provide information for the monitoring and management of remedial activities.  The objective of this research is to develop a polymer based material that can be used to quantify the concentration of chlorinated solvents in the groundwater through an electrochemical measurement.

Research Interest: Treatability of As-contaminated groundwater using a waste-product fishbone.
Development of techniques, procedures, and optimization methods to derive enhanced remedial technologies and sorbents through a process called biogenic templating. Utilization of biogenic materials as a template for remedial purposes may prove to be a cost-effective remedial approach for many heavy metals and other compounds, while also providing a use for common biogenic waste materials such as fishbones. Beyond material effectiveness, research further focuses on material characterization, fundamental science principals, and mechanisms of contaminant stabilization in various environmental conditions.

Research Interests: Treatment of combined sewer flow through ultrasonification
Project focus:
- Ultrasonic destruction of E. coli. with the help of TiO2: Efforts are being exerted to the activation of TiO2 by ultrasound waves to generate high disinfection capability.
- Protection of E. coli. by large-molecule substances:  In natural water systems, E. coli. may be protected by particulate matters or natural organic matters. So it’s worthwhile to study the mechanism underlying the protection effects to guide the design of disinfection devices for natural water systems.
- Electrochemical disinfection of combined sewer overflow

Research Interests: Diatomaceous Earth as a biotemplate for various contaminant removal compounds
Diatomaceous earth (DE), a cheap and abundant resource, can be used as a biotemplate for various materials.  The high surface area and non-reactive silicate structures make it an ideal template for coating.  Right now, I am working on coating the DE with different iron oxides and determining their efficiacy in removing excess fluoride from water.  Future research will involve different organic and inorganic contaminants as well as different polymers and metal oxides for coating.
