Research Interests

My background and interest in science education developed through experiences as a teaching faculty at the Trumbull Campus of Kent State University. Currently my appointment is with the Department of Biological Sciences-Kent Campus as a science education faculty member.

My education research interests involve studying the use of technology as a tool to enhance undergraduate education. The development of interactive multimedia computer tutorials and the use of stereoscopic 3-D imaging are the focus of my research.

My science background is strongly rooted in medicine and microbiology with interests in infectious disease of aquatic animals and examination of interactions microorganisms have with the biotic and abiotic environment. My laboratory is geared towards providing undergraduates opportunity to participate in research, and graduate students to participate in development of educational curricula and research involving technology.

Previous Projects

Bacterial assemblages associated with shredded tire landfills.

The bacterial community associated with leachate collected from shredded tire landfills and the colonization of tire shred material in both the field and the lab is the focus of this study.


Bacterial Biofilm growing on tire shred surface.

Investigation of chitinoclastic disease in crayfish.

Shellfish of many species suffer from a syndrome that leads to erosions and ulcerations of the chitinous exoskeleton. Commonly called shell disease, black shell disease, or burnspot disease, its cause has been attributed to several species of bacteria and fungi. The etiology of this infection in populations of Orconectes crayfish from Northeast Ohio is currently being examined.

Stereoscopic 3D imaging of anatomic structures and its use in teaching and learning.

Using 3D rendering software and two dimensional data from human cadaver sectioning, several stereoscopic 3D anatomy teaching lessons are being developed. The overall goal of this project is to compare learning of anatomic structures and their spatial relationships among various presentation modes; i.e., using 2D visualizations, 3D non-stereo, and 3D stereoscopic.
