Nam P. Nguyen Ph.D. Candidate in Computer Science Department of Computer & Information Science & Engineering University of Florida Email: nanguyen [AT] cise.ufl.edu

I am from Saigon - Vietnam and my full name in Vietnamese is Nguyễn Phương Nam. I am a fourth year PhD student in Department of Computer and Information Science and Engineering (CISE), University of Florida and a member of Optima Network Science Lab under the guidance of Professor My T. Thai.
Prior to my PhD, I received my BS and MS both in Applied Mathematics from Vietnam National University (2007) and Ohio University (2009).
I am currently on the job market. My current CV, Google Scholar, and Research & Teaching statements.

My research interests include dynamic complex network problems, such as Non-overlapping and overlapping network community structure, Worm and virus containment, Social networks; Cascading failures; Combinatorial optimization and Approximation Algorithms.

In particular, my current research focuses on the structural vulnerability of complex systems, especially dynamic systems. I am also working on the designing adaptive algorithms for effectively identify communities in dynamic networks such as mobile or online social networks, as well as their applications in different aspects of networking problems. In addition, I am also interested in effective methods to stop the propagation of virus or worm on large scale dynamic networks, in terms of both approximation and social-based algorithms.

• In Fall 2012, I am the full instructor of COT3100: Applications of Discrete Structures.
