Dr. Morales’ research lies within the broad area of statistical signal processing, with multi-disciplinary applications to wireless communications, computational biology, and financial engineering, among others. With a focus on inference and estimation theory under high-dimensional settings (big data), his research is aimed at providing contemporary signal processing solutions and machine learning methods, and at enhancing our current understanding of complex systems. Of particular interest are the challenges posed by the ever-growing dimensionality (e.g., users, antennas) of forthcoming wireless networks.
