My "real" position is Professor of Computer Science at Fordham University (Fordham College at Lincoln Center, to be precise). I am also an Adjunct Senior Research Scientist in the Columbia University Computer Science Department.

I do work in information-based complexity. I'm also on the Editorial Board of the Journal of Complexity. My special interests include the following:

- Complexity of partial differential equations.
- Complexity of integral equations.
- Complexity of ill-posed problems.

My Erdös number is four, via any of the following paths:

- A. G. Werschulz, J. F. Traub, J. B. Kruskal, A. J. Hoffman, P. Erdös
- A. G. Werschulz, J. F. Traub, W. S. Brown, R. L. Graham, P. Erdös
