PhD, Mathematics
Education:
My graduate studies in computer science actually began at UMASS Lowell but they were completed in information technology at Southern New Hampshire University (est. 1932). In the US computer science and information technology are two different but related disciplines. I suppose one could claim CS and IT are like two cousins rather than like identical twins.
Although my Masters degree is in IT, most of my undergraduate and graduate computer science and information technology courses were taught by professors with PhDs in computer science or in mathematics, at UMASS Boston/UMASS Lowell and at SNHU and who taught many courses common to both CS (UMASS) and IT (SNHU) programs.
(My graduate studies in pure mathematics are on hold right now due to reasons of poor physical health that prevent me from on campus attendance for classes. But Srinivasa Ramanujan was an absolute genius who got a much worse break than I did. Who said life was fair? It's not)

Postgraduate textbook used: Nonlinear Ordinary Differential Equations: An Introduction to Dynamical Systems, Jordan. D. W., Smith, P., Oxford, 1999).
Various Subjects/Topics I Covered in Computer Science
At the University of Massachusetts Lowell I completed graduate computer science courses (2012--2013) in relational algebra, data mining and knowledge discovery, SQL, computer network security and symmetric/asymmetric encryption, wireless security, digital forensics, cloud computing and virtual systems. I completed my graduate studies to fulfill the requirements for the M.Sc. at the Graduate Department of Information Technology at Southern New Hampshire University where I covered additional CS material on relational database design and software development, more SQL, Java, systems analysis and design, data communications, software engineering (including CASE and UML modeling), operating systems, computer simulation and animation and IT project management which covered some techniques from operations research like queues/waiting line modeling, network optimization, CPM, PERT and decision trees.
I have covered DES/AES/RSA encryption, block and stream ciphers, the discrete logarithm problem, the Diffie--Hellman algorithm, Dijkstra's algorithm, Hasse diagrams, message hash algorithms, knapsack ciphers, discrete mathematics which covered combinatorics, algorithms, the inclusion-exclusion principle, graphs, weighted graphs, bit complexity, Boolean rings, fuzzy sets, finite state machines, some algebraic coding theory over finite fields with the main application to linear Hamming codes.
Some of the undergraduate and graduate textbooks used (UMASS Lowell):
Discrete Mathematics and its Applications, Sixth Ed., K. H. Rosen, McGraw Hill, 2007.
Applied Discrete Structures for Computer Science, Second Ed.,
A. Doerr. K. Levasseur, SRA/Pergamon, 1989.
Computer Network Security: Theory and Practice, Jie Wang, Springer, 2009.
Computer Security: Principles and Practice, W. Stallings, L. Brown,
Pearson/Prentice Hall, 2008.
Research/Tutoring Experience (2002--):
Online mathematics tutor (volunteer) in undergraduate mathematics
Tutoring Subjects: Precalculus, College Algebra, Analytic Geometry, Differential and Integral Calculus, Advanced Calculus, Ordinary Differential Equations, Linear Algebra, Abstract Algebra, Complex Analysis, General Topology, Elementary Number Theory.
Researcher in elementary/analytic number theory, discrete mathematics (bit complexity, graphs and algorithms), stochastic processes, machine learning, mathematical physics. From 2002--2006 my mathematical physics research mentor was a physicist working in the field of theoretical quantum gravity/quantum field theory. Our joint refereed/published paper can be found in Foundations of Physics Letters (Kluwer), April 2005.
After I completed my undergraduate studies in mathematics, I was seeking for five years, a mathematics professor in number theory as a research mentor. Instead I wound up with a quantum gravity theorist as my research mentor. My input into our joint quantum gravity paper (I was the junior author) mainly had to do with fiber bundle maps (There is a great introduction to fiber bundle maps in the famous Munkres textbook on topology), regular polytopes, quaternions and octonions. I certainly appreciated his guidance and for refereed research he was a great guy to get to collaborate with, but since I had wanted a number theorist as a mentor to start out with, life never seems to take you where you want to go, does it? :-)
