Recent academic pursuits: Investigating (1) geometric control laws in a coordinate-free setting for constrained mechanical systems and a network of agents, (2) computing explicit bounds in the inverse function theorem and the implicit function theorem, and exploring applications that benefit from these, (3) exploring various facets of the discrete time Maximum Principle, with particular emphasis on frequency constraints, rate constraints and numerical techniques to solve two-point boundary value problems, (4) estimation algorithms on Lie groups - theory and computation.
