Applied mathematics is challenging because it requires a broad range of experience. My unusual career has given me the opportunity to work in a wide variety of areas:

- Probability
- Differential equations
- Large networks
- Complex analysis
- Numerical analysis
- Functional analysis
- Filtering
- Signal processing

A lot of so-called applied math is only *potentially* applied math because no one has done the hard work of actually applying it. I enjoy digging into real problems and doing whatever it takes to create a practical solution.

“John helped us solve a vexing and festering problem. Reducing it to mathematics and then to code required educated guesses, creative assumptions, intuition, deep knowledge of digital signal processing, and shots in the dark. This is where John excels: just the right mix of practical urgency with mathematical rigor. It’s difficult to overemphasize the difficulty of this problem and the acumen required to solve it completely and on a schedule. Just fantastic!” — Brian Beckman, PhD |
