About
Research
I am an applied paleobotanist, meaning that I study modern plants to better understand fossil plants. Plants, by their nature, are closely tied to the environments they live in. Paleobotanists use patterns of leaf size and shape to estimate paleoclimate. My research is focused on testing the underlying assumptions of these paleoclimatic and paleoenvironmental reconstruction methods. To do this, I primarily use herbarium specimens to study patterns of leaf physiognomy across geographical regions as well as within groups of woody dicot angiosperms.
