Research

I am interested in developing nonlinear theoretical models in order to interpret measurements in earth's auroral ionosphere of localized uni-polar fields (double layers), associated localized bipolar electric field structures and highly nonthermal particle distributions. I also study the excitation of these structures in a beam-plasma system.
