I'm an Associate Professor at Bryn Mawr College working in philosophy of mind and cognitive science. I completed my PhD at the University of Toronto in 2013, and my BA at Wellesley College in 2005. I teach courses covering a variety of topics in philosophy of mind, metaphysics, logic, early modern philosophy, and the philosophy of psychology and neuroscience. My introductory philosophy course was recently featured as a Bryn Mawr Cool Class.  

My research is on attention, consciousness, and perception. I am currently working on a Routledge Handbook on Perceptual Learning (co-edited with Kevin Connolly) that grows out of my research on the Interdisciplinary Study of Perceptual Learning. I am also working on a second book that explores the philosophical significance of perceptual differences more generally. For a list of my published papers and works in progress, see the section on my research below. When I'm not philosophizing, I enjoy going on adventures with my family, writing fiction for kids, and teaching our cat new tricks.

The Interdisciplinary Study of Perceptual Learning

People often say things like the following: Cabernet Sauvignon tastes differently to an expert wine taster than to a novice, or Beethoven’s Ninth Symphony sounds differently to a seasoned conductor than it does to someone in the audience hearing it for the first time. The examples just described are cases of perceptual learning—cases of long-term changes in perception as the result of practice or experience.

In the 2016/17 academic year, I explored the science and philosophy of perceptual learning as a visiting scholar at the University of Pennsylvania. This research was supported by a grant (co-authored with Kevin Connolly) from the Cambridge New Directions in the Study of the Mind Project. As part of this project, we coordinated two interdisciplinary workshops. You can read more in the workshop reports written by our graduate student associates.
