Teaching


Plant Physiology, BOT 3463, every spring and fall (in fall only as online course). Prerequisite: BOT 1404 (Plant Biology).

Plant Physiology Lab, BOT 3462, every spring. Prerequisite: Plant Physiology (BOT 3463) or concurrent enrollment.

Plant Mineral Nutrition, BOT 5423/4423, fall of odd numbered years. Prerequisite: Plant Physiology (BOT 3463).

Research


My group studies the physiology and evolution of plant membrane transport proteins. Ongoing research project are:
- Annotation and analysis of the genome of the thermoacidophilic red alga Galdieria sulphuraria.
The analysis of the Galdieria genome has been published in Science - see here.

- Recording and modelling of pH homeostasis in plant root cells (funded by OPSR - OCAST).
