The goal of my research is to understand the computational power and limitations of distributed systems. Distributed systems are everywhere: familiar examples include computer networks, social networks, ant colonies, and the human brain. Like all distributed systems, each of these examples consists of a set of entities (computers, people, ants, neurons) that operate autonomously, and interact with one another and their local environment in order to perform some task.
In my work, I study abstract computational models of distributed systems. Such models were developed in order to understand computer networks, yet they are relevant to the study of all distributed systems---not just man-made computers. Thus, my work has addressed a broad range of problems arising in the sciences: stable matching theory in economics, packet forwarding in networks, local and sub-linear time graph algorithms, network verification, and clock synchronization. While these topics are superficially disparate, I seek to find an underlying unity between fields using the language and techniques of distributed computing.
I am thrilled to teach all levels of computer science courses, from introductory programming to advanced seminars on theoretical computer science. Computer science is remarkable in that it interfaces with nearly every other field of study. I highlight these connections in the classroom by studying problems relevant to other disciplines.
My courses emphasize the conceptual aspects of computer science. My goal is for students to achieve fluency in "algorithmic thinking," which I believe to be valuable independent of any computing technology. By combining practical and theoretical approaches, I hope to give students the tools necessary to reason about and impact the world around them.
