About Me

I have accepted a postdoctoral position at Toronto Metropolitan University (formerly Ryerson University). This page may be out of date!

I am a postdoctoral scholar at the University of Manitoba in Winnipeg, Manitoba, Canada where I am working with Dr. Karen Gunderson and Dr. David Gunderson.

My primary research interest is the study of properties of large networks. In particular, I use the tools of extremal and random graph theories to find guaranteed or typical properties of networks with sufficient size or other characteristics. As an undergraduate I was also interested in the fields of computational complexity and computability.

I was a Ph.D. candidate at the University of Nebraska–Lincoln under the supervision of Dr. Jamie Radcliffe. I graduated in May of 2020. I also earned a Master of Arts in Mathematics from the University of Nebraska–Lincoln in 2017.

In 2013, I graduated from Carnegie Mellon University with Bachelor of Science degrees in Computer Science and Discrete Math and Logic.
