Ram Durairajan is an Assistant Professor in the Department of Computer and Information Science at the University of Oregon. With his colleague Prof. Reza Rejaie, Ram co-leads the Oregon Network Research Group (ONRG). Ram earned his Ph.D. and M.S. degrees in Computer Sciences from the University of Wisconsin - Madison and his B.Tech. in Information Technology from the College of Engineering, Guindy (CEG), Anna University.

We are looking for motivated students to work with us at ONRG starting in the Fall of 2018. For more information, please see here. Feel free to drop me an email with your CV.

RESEARCH

Ram's research vision is to create a "robust Internet" by understanding the Internet's structure and behavior through principled measurements. To that end, Ram is developing techniques for (i) measuring and analyzing the topological structure of the Internet, (ii) measuring and understanding end-to-end path dynamics, and (iii) designing scalable and deployable systems to mitigate risks and outages.

Broadly speaking, Ram has addressed research questions in several areas of computer networking including network measurements and analysis, network economics, large-scale network simulations, debugging and testing in software-defined networks, mobile and wireless communication, Internet of things, visualization and security, and datacenter transport protocols.
