Research/Professional Background Highlights

I am interested in using molecular genetic tools using the model plant Arabidopsis thaliana to understand molecular and biochemical processes such as how organisms interact with plants. Currently, I am investigating compounds called phytotoxins that interfere with a plant’s ability to germinate. Organisms that either compete with plants for resources or that are plant pathogens produce phytotoxins as a means to interfere with necessary functions of plants. In many instances, plants, in turn, have evolved the ability to detect phytotoxins in order to mount a defense response. By studying how phytotoxins affect Arabidopsis, we can learn about the toxicity of these compounds, and also learn about the interaction of plants with their competitors and pathogens.

On the Biology Department:

Our department has a very strong commitment to providing our students the opportunity to engage in a very meaningful research experience. This is offered through our research courses offered during the academic year that involves numerous activities and development of skills that students would find difficult to gain at other institutions and that prepare our students well for post-graduate programs or research. We also run a summer research program through which students can experience a less structured research experience.

The University has a long tradition of encouraging and supporting study abroad.

More than 47 percent of Redlands undergraduates participate in study abroad programs.
