I am
interested in bringing undergraduates, and graduate students alike, on a
safari. A fitting image for my research activities is that of the wisemen,
each with a different perspective, trying to identify the proverbial
elephant. Most projects consist of applying several techniques to study a
system, using mathematical models to interpret the particular beast.
Depending on interest, the focus of a student’s research may be more on
the wisemen or more on the elephant. |
