Our faculty members are scholars who actively contribute to their disciplines of interest — such as linear algebra, operations research, graph theory, differential equations, probability, statistics, approximation theory, dynamical systems, numerical analysis, wavelet analysis, enumerative combinatorics, spline functions, computational mathematics, design theory, algorithmic number theory, cryptography, functional differential equations, stability theory, monotone iterative techniques and generalized quasilinearization.
Our students have contact with these active professionals from day one as freshmen.
Our faculty welcome student collaboration, both in class and through independent research projects under their guidance.
