I was born and raised in Indiana, spent many years studying, working and living in New England and have a passion for algorithms and education. My research revolves around heuristic search and planning, which applies to things like navigation, robotic movement or selecting actions for video game AI characters. I am also interested in the human aspects of computing, such as computer science teaching pedagogies and ways that systemic bias is embedded in algorithm design.
I believe that a liberal arts approach to computer science is a vital part of ensuring that computers work for the good of all of us. I’m excited to engage with Earlham students in computing work that actively integrates our values and reflects an understanding of the impact that computers and humans have on each other.

My research has primarily been on heuristic search and planning, especially making faster algorithms for solving shortest path problems. I’m especially interested in applying these to navigation, logistical planning, and robotics. One area I am also excited to work with students in is algorithmic bias: detecting the reflections of systemic bias in algorithms, examining the effects it has on people, and devising algorithm design practices to combat bias.
