About Me

I am an Emerging Political Economies and Applied Complexity Postdoctoral Fellow at the Santa Fe Institute, where I work with Matt Jackson, Eleanor Power, and Fiona Steele on statistical inference for complex network sampling techniques. I recently completed my Ph.D. at Duke University advised by Alexander Volfovsky and Eric Laber. My dissertation research focused on creating methods for the study and assistance of hard-to-reach populations.
