My research explores the physiological-basis of how plants interact with their environment, and how these interactions impact broader patterns in plant ecology. I have conducted research examining many aspects of plant stress tolerance and more recently investigated the role of the
plant vascular system, specifically the phloem, in determining patterns of plant growth and reproduction. My research spans the fields of plant physiology and ecology, and I have studied a variety of plant species from willows (Salix) to giant pumpkins (Cucurbita maxima). I am
currently examining how seasonal changes in the vascular system impact the timing of flowering and leaf out in the spring. This work will help us better understand the physiological basis of plant phenology and seasonality, two factors that are critical in understanding species current and
future geographic distributions.
