Welcome to sjero.net


sjero.net is the personal website of Samuel Jero, a doctoral student studying computer science at Purdue University. My research interests include networking protocols, delay tolerant networking, distributed systems, operating systems, and security. I am a member of Dr. Cristina Nita-Rotaru's Dependable and Secure Distributed Systems Lab (DS^2) at Purdue.

I am currently working on several projects including automated vulnerability detection (with Hyojeong Lee) and examining byzantine fault tolerance for software defined networks.

I am also coordinating a reading group/seminar on Software Defined Networking (SDN) at Purdue. You can find more information about that group here.

My masters and undergraduate work was in computer science at Ohio University. I was a member of Dr. Shawn Ostermann's Internetworking Research Group (IRG) there. We worked with NASA to maintain and improve the Interplanetary Overlay Network (ION), a software package for communication with satellites in deep space.

During my undergraduate and masters work I also did research into the Datagram Congestion Control Protocol (DCCP) with Dr. Ostermann. We examined DCCP's performance relative to TCP in testbed, Internet, and high delay environments. Along the way we identified and fixed several major bugs in the Linux implementation and developed a new visualization tool. My masters thesis developed out of this work and examined the performance of DCCP for real-time, streaming media applications. You can learn more about my work with DCCP here.

When I'm not working on computer science research, I also enjoy live audio production. While at Ohio University, I was the the tech crew leader for Cru at OU, a Christian student movement on campus, for four years. As tech crew leader, I was responsible for the setup, tear down, live mixing, recording, and editing of our weekly praise and worship gathering called 180 (every Thursday night at 9pm during the school year). This event brought out about 350 students every week. I also had the privilege of helping Purdue Cru in a similar capacity for a year.
