Research in my laboratory focuses on understanding the molecular and cellular mechanisms underlying the biogenesis of lipid droplet in plant cells and applying this knowledge towards bioengineering neutral lipid accumulation in the vegetative tissues (e.g., leaves and stems) of plants. Our research also takes advantage of a wide range of cellular and molecular technologies, as well as biochemical and microscopic approaches. If you are interested in this research, please contact me about opportunities in joining our group.

Complete Publication Listing.

At the undergraduate level, I am involved in teaching Advanced Cell Biology (MCB*4010) and co-teaching Molecular Biology of the Cell (MCB*2050). I also participate in various courses (i.e., MCB*4500, MCB*4510 and MCB*4600) that provide research opportunities for senior undergraduates to join my laboratory, work in close collaboration with graduate students and/or post-doctoral associates and undertake a research project on a topic related to plant cell and molecular biology. For more information on these types of research opportunities, please contact me directly.
