Research:

My primary interest is in the molecular and cellular basis of developmental transitions in plants. We study both the changes themselves and the molecules that regulate or mediate them. Our approaches are varied, ranging from transcript profiling to immunoEM. Gene redundancy is one of the recurring challenges of our work, and we typically use Arabidopsis because of its power as a genetic system. It is not unusual for us to create quadruple or quintuple mutants in our efforts to unravel the threads and reveal the contributions of different gene products.

Courses:

I regularly teach Introductory Biology (Bio 151/153, Bio 152) and General Botany (Bot 130), as well as Plant Cell Biology (Bot 860, spring semester, even-numbered years) and Regulatory Aspects of Plant Development (Bot 840, fall semester, even-numbered years). Students interested in independent study opportunities in the lab should contact me at dfernand@wisc.edu.
