Expertise: Control theory of distributed parameter systems; nonharmonic Fourier series; inverse problems of mathematical physics; signal processing (sampling and interpolation of band-limited and multi-band signals, spectral estimation); partial differential and differential-difference equations; control and inverse problems for differential equations on graphs
Research: I study the interaction between Pluto’s atmosphere and the solar wind by comparing spacecraft data with computer simulations.
Expertise: study of configurations of points and lines with high degrees of incidence and/or symmetry, especially developing new construction techniques and examples; study of abstract polytopes and their monodromy groups, with an emphasis on polytopes that are symmetric but not too symmetric; discrete geometry
Expertise: experimental design, spatial statistics
Expertise: the role of nutrition and physical activity in the development and prevention of chronic diseases; epidemiology; prevention science; determinants of dietary and physical activity patterns; development and evaluation of theory-based interventions; minority health, particularly indigenous populations
Expertise: climate variability which aims to understand how one component of the climate system influences another (e.g. ocean and atmosphere) and attempts to explain why something happens; Arctic tundra vegetation changes linked to climate; dynamical downscaling of climate information for Alaska; fire weather in Alaska
