Center for Biofilm Engineering, Montana State University, Bozeman, MT

National Science Foundation Undergraduate Research FellowshipSummer 1999

Research Project: An Optical Method to Detect and Monitor Biofilm Accumulation

Conducted a summer-long project to build and test a prototype laser-based optical sensor to monitor real-time biofilm growth inside a laboratory bioreactor. Project resulted in a successful proof-of-concept that could be further developed into a device to assist in the monitoring and control of laboratory experiments.

Intern Summer 1998

Created an internal website to organize information for researchers, and created a database of biofilm images for use in presentations and publications.
