New signal processing theory, models, and algorithms are needed to address growing demand for new scientific and biomedical imaging capabilities that exceed physical limits due to wavelength or acquisition speed. Doctors will be able to study and diagnose diseases in living subjects at greater levels of detail, revealing new insights and improving accuracy. Microscopes will be able to locate and track molecules and cells in three dimensions with unprecedented precision. Our research focuses on driving the field forward by constructing image and measurement models and combining these models with new, computationally efficient reconstruction algorithms suitable for practical use.
