Nick's research has covered a broad area of industrial, applied, experimental, and theoretical physics. A main theme in his work is the analysis and modeling of nonlinear behavior with a strong inclination toward the methods of computational science (A dynamical systems approach to behavioral modeling, HP Labs Technical Report 1999-22). During much of the last decade he worked as a industrial R&D engineer doing advanced modeling of RF, microwave, and optical devices and related measurement instrumentation. Most of the engineering applications of this work where geared toward the high-speed wireless and optical communications industries and include high precision equalization and calibration baseband signal processing algorithms, simulation based methods to speed up the manufacturing test of electronics, and the creation of behavioral models capturing the nonlinear performance of electronic components.
His most recent interest is the development of instrumentation, hyperspectral remote sensing algorithms, and related computational models for the complex processes associated with hydrologic science: specifically water quality and water flows both at the surface and subsurface (Measuring stream dynamics with fiber optics, Agilent Measurement Journal, Issue 3, September 2007).
