Research Interests
My present interests are in the area of basic hypergeometric
series and related areas.
I am currently also working on various problems related to
continued fractions.
I have also investigated various convergence problems for
qcontinued fractions, and I and my thesis adviser, Douglas Bowman,
recently partially settled a longstanding open problem on the
convergence of the RogersRamanujan 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.
