Research Interests

The goal of my research is to develop computer vision, machine learning, and graphics techniques to understand, analyze, and visualize how the world changes over time. Much of the current work in my research group focuses on two ongoing lines of work:

  • Understanding, visualizing, and analyzing anomalies and changes in months- and years-long webcam and livestream footage.
  • Analyzing satellite and drone imagery to investigate legibility of international borders (with applications in Political Science) and identify and count birds, nests, and woody debris in stream ecosystems (with applications in Ecology).


I am always looking for motivated students to get involved in my research. If you are a current WWU undergraduate or MS student interested in working with me, send me email or stop by my office.
