We develop advanced microscopy techniques to provide contrast between cell and tissue components that are difficult to resolve with traditional stains and dyes. We do this by leveraging the physics of light-matter interactions, incorporating nonlinear optics and real-time digital signal processing techniques. We are particularly interested in FPGA-based signal processing, sub-picosecond time-resolved optical interactions such as transient absorption, and applications of deep learning to regression problems like signal estimation and denoising.
