This research opportunity focuses on probabilistic techniques in Air Force applications such as turbulence estimation, search and detection of randomly moving multiple targets, sensor fusion, and nonstationary signal detection. We are interested in modern techniques in stochastic analysis for random process with jumps such as Levy process, optimal stopping techniques, and nonlinear filtering techniques. Large deviation theory plays a significant role in the analysis of search and detection methods with Poisson distributed sensors and also in the assessment of the impact of noise in turbulent flows. Other Air Force applications of large deviations such as risk analysis and estimation of rare event probabilities for failure analysis are also within the scope of this research program. Also of interest are approximation techniques for the nonlinear filtering equations of Fujisaki-Kallianpur-Kunita equation and the Zakai equation to derive practical algorithms extending the Kalman filtering technique and sequential Monte Carlo techniques, such as particle filtering. Research problems in hypersonic aerodynamics are of top priority. Novel methods to combine techniques from statistical and machine learning and also sparse methods and compressed sensing to stochastic analysis and control of fluid dynamics and turbulence estimation is also of interest.
