Research and Teaching Interests

My overall research interests are focused on both development and effects of abiotic stress on plants, with a specifically interest in how the plant hormone cytokinin is involved in these processes. My lab uses molecular, genetic, and physiological approaches to study a set of transcription factors known as Cytokinin Response Factors (CRFs), which are regulated by both cytokinin and stress. A major goal of my research is to understand the function of cytokinin in its different forms throughout essential plant processes, development, and during stress. These examinations are primarily conducted in Arabidopsis and tomato and often have a CRF based focus. My teaching interests parallel my research interests and are focused on plant biology, development, and plant hormones.
