Katie Becklin, Ph.D.
Katie holds a B.S. in Biology from the University of Puget Sound and a Ph.D. in biology from the University of Missouri. She is currently an IRACDA postdoctoral fellow conducting research with Prof. Joy Ward in the Dept. of Ecology and Evolutionary Biology at KU. Her research aims to 1) understand physiological, ecological, and evolutionary mechanisms generating variation in species interactions, and 2) trace the impact of such variation on ecological interaction webs. She pursues these research goals by studying mycorrhizal associations, symbiotic interactions between plants and root-colonizing fungi, using an interdisciplinary approach that spans multiple spatial and temporal scales. Katie is focusing on how long-term changes in atmospheric [CO2] since the last glacial period alters the functioning of mycorrhizal associations, and how such changes may generate feedbacks that alter plant productivity and plant and fungal community composition.
