TEACHING

  • Experience teaching a wide range of courses, including introductory undergraduate courses, assembly language, data structures, file structures, cryptography, computer security and secure electronic commerce courses (both undergraduate and graduate), mathematics for computer science, undergraduate and graduate algorithms, research-oriented special topics classes (including trusted computing and software security), and several advanced graduate seminars (topics: data compression, on-line algorithms, randomized algorithms, Java and network security, and cryptography and security).
  • Worked with other faculty to expand computer security courses at UNC Greensboro from a single course to a three-course series (with additional courses as "special topics" classes).
  • Created and maintained a five-module interactive Python tutorial, using Runestone Interactive tools; used in multiple UNCG classes (CSC 100, CSC 101, CSC 110, and CSC 120), and in UNCG's Master's in Informatics and Analytics "Python programming bootcamp" (2017 - present)
  • Re-implemented a "fractal explorer" in JavaScript, based on an earlier Java applet from Ron Eglash at Rensselaer Polytechnic Institute (RPI). This was used to teach recursive constructions in a culturally-situated context, and has been used in my UNCG CSC 100 class, as well as by RPI and others.
  • Created and led a Living-Learning Community for freshman computer science majors, 2014-2015.
  • Organizing committee and computer science lead, AToMS Living-Learning Community, a residential cohort-based learning community for computer science, chemistry, physics, and mathematics freshmen. 2012-2014.
  • Participated in the UNCG Veteran and Military Affiliate Education Institute, June 2013.
  • Member of the UNCG delegation to an AAC&U Summer Institute on Integrated Learning, Burlington, VT, July 2012.
  • Designed a custom version of the UC Berkeley "Beauty and Joy of Computing" class for UNC Greensboro (offered as CSC 100). While following the UC Berkeley outline, our version has a full set of locally-developed lectures and extensive lab exercises. Worked with teachers at a local high school (Weaver Academy) to offer this course at the high school as well. Designed around the College Board's "CS Principles" course/exam, we now offer credit for this class to high school students who make a 3 or better on the AP CS Principles exam. Offered for the first time Fall 2012.
  • Designed an innovative class (CSC 110: Computational Problem Solving), taking a creative approach to teaching mathematics concepts and problem-solving skills as part of the UNC Greensboro general education curriculum, 2009.
  • Organized and supervised a group of 6 directed study students who performed a formal security audit of the Department of Computer Science systems and network (Fall 2005).
  • Organized and coached a team of 8 students (including 2 from the Department of Information Technology and Decision Sciences) for participation in the 1st Texas Collegiate Cyber Defense Contest, San Antonio, April 2005 (travel funding from Microsoft).
  • Designed and established a multi-course sequence in computer security at both undergraduate and graduate levels at the University of North Texas. Applied for and received two federal certifications, showing a mapping of our computer security courses to two the Committee for National Security Systems (CNSS) training standards 4011 (for Information Security Professionals) and 4013 (for Secure System Administration).
  • Participated in teaching workshops on secure electronic commerce and network security (Washington D.C., March 2003; Tulsa, OK, July 2003).
  • Organized and supervised a group of three graduate students in the Honeynet Reverse Engineering Challenge, placing second in this international competition (May-June 2002).

Individual Student Mentoring

  • Supervised 13 master's students at UNCG (4 thesis; 9 project)
  • Mentored approximately 30 undergraduate students in Senior Project work, 2007-2018.
  • Mentored three students in UNCG Honors Contract courses and projects
  • Five graduated Ph.D. students at UNT (Brent Chapin, 2001; Ke Xu, 2004; He Ge, 2006; Vandana Gunupudi, 2007; Ping Yu, 2008).
  • Served or currently serving on 18 Ph.D. committees and 7 Master's committee at UNT (other than my own students).
  • External reviewer and Ph.D. committee member for a student (Elliott Landowne) at the City University of New York.
  • Supervised over a dozen students (both at undergraduate and graduate levels) in directed study and independent projects.
