Rachel Spicer is interested in how woody plants adapt, evolve and survive in different environments. Research in her lab is focused on the biology of trees, shrubs and lianas – anything with a large woody stem – and includes projects on how woody stems develop, age and transport water to the leaves.
Trees face particular challenges as plants because of their long lives and massive plant bodies. Dr. Spicer is interested in how the structure of wood affects the overall physiology of a tree, how development of the woody stem is affected by the environment, and how these two processes interact. More recently, she has been studying wood development using the molecular model species Populus by combining tools from molecular biology, physiology and classical plant development.
In Fall 2013, Dr. Spicer was awarded a three-year, $395K grant from the National Science Foundation titled "Auxin dynamics during vascular development in the model woody plant Populus." The focus of this research is to track the flow of the plant hormone auxin as it moves from young developing leaves down into the stem, where wood is just starting to be produced. In addition to providing funds for state-of-the-art equipment and supplies, this grant will support student research during the academic year and provide summer stipends for up to ten students doing independent research toward senior theses.

Work in Professor Spicer’s lab always seems to involve developing a new technique to measure or see something that no one has ever measured or seen before. If you are an undergraduate who likes to tinker, build things, learn new techniques and experiment in the true sense of the word, Professor Spicer encourages you to please stop by New London Hall and say hello.
