Dr. Andrew R. Roosen, Mathematician
This is my research hat. My Ph.D. is in mathematics
from Rutgers University where
I studied under Jean Taylor.
I haven't proven any theorems since then, however, so you might say I'm
a lapsed mathematician.
Here's a list of my research interests, past and present, in no particular
order. All of them have relied heavily on the efforts of collaborators:

Wulffman, a tool
for computing Wulff shapes with specified symmetries.

Motion of fullyfaceted interfaces. This includes my thesis work and the
projects that have developed from it including:

Solidification of a pure material from its melt

Surfacediffusion and surface attachment limited kinetics

Growth and coarsening of multiple particles, in particular Si_{3}N_{4}.

Reactive wetting
as a solder drop spreads over a reactive substrate.

OOF: the ObjectOriented
Finite Element solver for examining microstructures
