Research interests

Mathematical analysis, particularly operators on Hilbert space; complex analysis; H infinity control.

Current research

I am collaborating with Jim Agler (UC San Diego) and Zinaida Lykova (Newcastle University) on a) function theory and geometry of the symmetrised bidisc and b) the extension of some classical theorems of function theory to functions of two or more variables. I am also writing a book with Jim Agler and John McCarthy on the use of operator theory in complex analysis.
