Sang-Yoon Chang

Welcome to my page. I am an Associate Professor at the Computer Science (CS) Department at University of Colorado Colorado Springs (UCCS). My main research interest is in security of networked systems. At UCCS, I teach: Intro to Computer Security (CS 4910), Applied Cryptography (CS 4920/5920), and Wireless and Embedded Systems Security (CS 5960), and Computational Linear Algebra (CS 2300). In addition to the courses at UCCS, I offer MOOC courses in Applied Cryptography at Coursera. I am also the PI and the Director of the CyberCorps Scholarship for Service (SFS) program at UCCS, the Colorado-Washington Security Scholars Program (CWSSP).

I received my PhD and Bachelor's degrees from the Electrical and Computer Engineering (ECE) department of University of Illinois at Urbana-Champaign (UIUC) in 2013 and 2007, respectively. . Before joining UCCS CS, I was a postdoctoral fellow at Advanced Digital Sciences Center (ADSC), a UIUC research center at Singapore.

For Prospective Students, please see here for general information and here for the lab seminar policy. I enjoy working with driven and smart students! Also, if you are interested in working in the US government sector as a cybersecurity expert after university, please check out our CyberCorps Scholarship for Service (SFS) program, Colorado-Washington Security Scholars Program (CWSSP) for more information: CWSSP.
