Research Description

Rebecca Willett's research is focused on developing machine learning and signal processing theory and methodology that exploit underlying low-dimensional models, including sparse and low-rank representations of data. In particular, she has studied methods to leverage low-dimensional models in a variety of contexts, including when data are high-dimensional, contain missing entries, are subject to constrained sensing or communication resources, correspond to point processes, or arise in ill-conditioned inverse problems. This work lies at the intersection of high-dimensional statistics, inverse problems in imaging and network science (including compressed sensing), learning theory, algebraic geometry, optical engineering, nonlinear approximation theory, statistical signal processing, and optimization theory. Her group has made contributions both in the mathematical foundations of signal processing and machine learning and in their application to a variety of real-world problems. She has active collaborations with researchers in astronomy, materials science, microscopy, electronic health record analysis, cognitive neuroscience, precision agriculture, biochemistry, and atmospheric science.
