Short: I carry on both fundamental and applied research in the area of Statistical Signal Processing.
My Theoretical work is somewhere in the frontiers of statistical signal processing, Bayesian analysis, statistical learning, computational and robust statistics. Some Applications: satellite-based navigation (GNSS), indoor localization/tracking, multiple object tracking, multi-sensor data fusion, wireless and deep space communications, intelligent transportation systems, air/unmanned traffic management, computational biology and life sciences.
Primary Research Lines:
1) Robust Statistical Inference in Dynamic Complex Systems
2) Statistical Signal Processing for Advanced GNSS Receiver Design
3) Robust Indoor Localization, Tracking and Navigation
Statistical inference/stochastic filtering: infer time-varying hidden quantities (states/parameters) from a set of available observations. Dynamic complex systems: time-varying, nonlinear, non-Gaussian, potentially high-dimensional systems, with an important model uncertainty. Robustness: how to deal with deviations from model assumptions (uncertainties, inaccuracies, model mismatch).
