Research Interests
Geometric or information-theoretic optimality principles in the analysis of data. Linear and non-linear representations and accuracy in signal acquisition such as quantum communication and analog-to-digital conversion.
  1. Sparse recovery in function spaces modelling analog signals, with applications to seismic imaging, X-ray crystallography, and human mobility data.
  2. Multiresolution methods and statistical analysis for biomedical imaging, see the featured story.
  3. Multiresolution analysis with directional selectivity in multidimensions and applications in CT imaging, see the featured story.
  4. Optimal quantum state estimation, including binary measurements, see the related presentation.
  5. Optimal and near-optimal subspace arrangements for high-dimensional parallel computing with fusion frames.
  6. Frames as codes: Controlling errors in analog-to-digital conversion with redundant representations, and the recovery of data loss in digitized transmissions of analog data.
  7. Characterization and design of equiangular tight frames.
  8. Uncertainty principles in filter design.
    The topics covered in my research often have an inter-disciplinary motivation, for example biomedical or seismic imaging, quantum communications and even the analysis of geospatial data such as traffic counts. When exploring these subjects, the focus is on fundamental mathematical insights which shed light on the inner workings of applications. For more details, see a list of key publications with comments.
