Areas of expertise: - Classical control (Root-locus, Bode and Nyquist diagram, Routh-Hurwitz stability criteria etc.) - Optimal control theory (Pontryagin's maximum principle, Euler-Lagrange equations, singular optimal control problems etc.) - Nonlinear control theory (Limit cycle, Lyapunov stability theory, behaviour of chaotic dynamic systems etc.) - Mathematical optimization or mathematical programming (Linear and nonlinear programming using GAMS)
