## Research and Practice Interests

My research interests lie within complex analysis, broadly interpreted. In the past quater century my work has focused on the role of conformal metrics, especially the hyperbolic metric, within complex analysis. Roughly speaking, the idea is to obtain a conformal geometric understanding of classical parts of complex analysis, and then use this new geometric insight to generalize the classical results to new contexts. Many classical results are conformal and two-dimensional; as such they do not readily extend to other contexts. On the other hand, a geometric formulation frequently does extend.
