Applied mathematics is the application of mathematics

to solve some sort of problem of importance, typically

in science or engineering. It is a bit different in pure

mathematics, in the sense that pure mathematics will

try to understand something theoretical purely for its own

intrinsic interest. Now many of that work in pure

mathematics may eventually have applications, but in

pure mathematics you're not necessarily really trying to

directly address some kind of problem. In applied

mathematics you typically have some sort of problem that

can be solved much more efficiently by using some sort of

theoretical approach, or mathematical approach. So

typically you use mathematics to build some sort of model

of the system, and you use that model to gain

understanding of the system or to predict its behavior, so

you can use that model in designing a better system,

for example.

I mainly apply mathematics to improving the efficiency of

manufacturing processes. The particular type of

mathematics that I work on involves what is known as

control theory, which is the control of particular systems –

basically to make systems do what you want them to do.

The particular type of manufacturing processes that I

work on involve bringing molecules together in just the

right way to form some high-value-added product. The

kinds of specific applications that I look at include

pharmaceutical manufacturing - making pure

pharmaceuticals, or to have higher efficacy; systems

nanotechnology where we try to develop new

nanotechnology devices. As well as micro-processes, such

as micro-electronics.

I like to exercise. Primarily bicycling, cross-country skiing

and walking. I really enjoy doing this either in the

Massachusetts area, or in southern Vermont and

New Hampshire because there's lots of parks in the area

with lots of hills and lots of trails. And they're pretty

heavily under-utilized so you have a lot of time to think

about what you're doing, and what kind of work and ideas,

but you can also chit-chat with colleagues who go off with

me. But most of the time I don't have the time to go all

the way out there so I just commute to work and back either

bicycling or walking.
