Professor Henrik Aratyn works in Theoretical Particle Physics and Mathematical Physics. He holds a Ph.D. in Physics from the Niels Bohr Institute (1984). He joined the UIC Faculty in 1987 after 3 years as a Postdoctoral Researcher at the Hebrew University and the Ohio State University. His current scientific interests include: Kadomtsev-Petviashvili hierarchies of the soliton equations, the affine Lie algebraic methods and the dressing techniques, (3+1)-dimensional integrable theories and Hopfions (static, soliton solutions with non-zero Hopf topological +charges), Toda field theory, topological charges, the Skyrme model, BRS techniques and quantization, methods for constrained systems, supersymmetry, non-linear dynamical systems, conformal field theory and W-algebra, Yang-Baxter equations, and Knot theory.
