Research Interests

Plastids are amazing plant cellular organelles that can exist in several different forms. The most commonly known and visible plastid type is the chloroplast characterized by its green color due to accumulation of chlorophyll. Chloroplasts carry out many different essential biochemical processes, including photosynthesis, fatty acid synthesis, sulfur and nitrogen assimilation and hormone synthesis, among others. The next most commonly seen plastids are chromoplasts (red, yellow, orange types found in fruit and autumn leaves) and amyloplasts (the starchy plastids in potatoes, for example). Plastids are dynamic and can convert between types when given the correct developmental signals. The research in my lab is to examine the role of certain proteins in the function and development of plastids. We are especially interested in the interaction between light and plastid dynamics. We make use of model plant systems (Arabidopsis thaliana, Arabidopsis and Lycopersicon esculentum, tomato) and iridescent ferns. We use molecular genetic, physiological, and biochemical approaches in our research
