I once researched nonlinear control theory, very abstract stuff! So glad that I left the field…
If you’re willing to consider different career path, try a) risk management in the insurance field. There is an article on the latest Fortune magazine talking about the hard science behind risk models, and that may interest you and some of your experience may apply. And b)a quant career on the wall street (financial services industry, asset management) could be possible.
These are two that come to mind. I’m not ware of academic/research positions.
