Nancy and I also organized special sessions on continued fractions
at the 2006 Joint Meetings in San Antonio and 2004 Joint Meetings in Phoenix.

Research Interests
My main areas of interest are in Number Theory.
I am currently working on various problems related to continued fractions.
Some of this work concerns the problem of finding polynomial solutions to
Pell's equation (thereby being able to write down expressions for the
fundamental unit in infinite families of real quadratic fields).
I have also investigated various convergence problems for q-continued
fractions, and I and my thesis adviser,
Douglas Bowman,
recently partially settled a long-standing open problem on the convergence
of the Rogers-Ramanujan continued fraction on the unit circle.
I am also interested in the problem of finding the regular continued fraction
expansion of a number expressed in some other form (for example,
as an infinite series or infinite product) and finding numbers with
predictable patterns in their regular continued fraction expansions.
Another area of interest is the evaluation of polynomial continued fractions.
I am also interested in various problems in the area of
Diophantine equations.
