Research Interests:

The role of wetlands in controlling algal blooms by reducing nutrient loading to Lake Erie
This project is done in collaboration with the research team at Old Woman Creek National Estuarine Reserve. Old Woman Creek National Estuarine Reserve is a shallow wetland located in Erie County along the south-central shore of Lake Erie. The goal of the research project is to evaluate the role of wetlands in reducing nutrient loading to Lake Erie. Understanding how storms and wetland connectivity to Lake Erie impact nutrient retention by coastal wetlands is important for managing and/or restoring wetlands .

Role of subject-specific acceleration in gifted education
Our goal in this project is to evaluate the effectiveness of subject-specific acceleration in chemistry among gifted learners in elementary and middle schools This research project is being done in collaboration with the Regional Center for Advanced Academic Studies. An accelerated curriculum in chemistry is being developed and student learning outcomes and new learning assessment tools are being developed.  This project is funded by the Randolph J. and Estelle M. Dorn Foundation and the Materials Research Society’s grassroots awards.

Antimicrobial activity of polymers from Flavonoids
This project is done in collaboration with Dr. Ram Veerapaneni.  We are interested in investigating and enhancing the antimicrobial properties of flavonoids. To further enhance stability and efficacy, these natural compounds are modified using environmentally friendly methods. The synthesized compounds are being tested their efficacy as antimicrobial agents. This research is funded through a grant from the Center for Undergraduate Research (CURS) at BGSU.

Environmentally friendly hybrid formulations for the removal of cyanobacterial toxins
Cyanobacterial toxins have been proven to be capable of poisoning both aquatic species and humans upon acute or prolonged exposure. Nanoparticles based on titanium dioxide have been reported to photocatalytically inactivate different cyanotoxins. However most of these photocatalytic experiments have been performed under reaction conditions which do not reflect the actual composition of water and pH conditions in a Lake or Estuary. The goal of this project is to develop benign and environmentally friendly formulations based on TiOdispersions with photocatalytic activity in the visible region. This project is funded from a seed grant through the Office of Sponsored Programs and Research.
