    My research focuses on designing algorithms and hardware for novel compressive hyperspectral imaging systems for microscopy and for 3D hyperspectral reconstruction - Designed and implemented a novel training algorithm for multi-rate neural networks for compressed domain image classification on compressive samples acquired by the single-pixel camera. The multi-rate network is capable of predicting over a range of compressive measurement rates instead of a single measurement rate. - Designed and built a compressive hyperspectral reflection/transmission microscope using a single spectrometer as detector and used it to measure spectra of gold nanoparticles and fluorescent microspheres. The system is low-cost and fast compared to conventional hyperspectral microscopy methods. - Designed and built a low-cost hyperspectral projector system that generates programmable hyperspectral structured illumination based on a single digital micromirror device. The system is used for reconstruction of hyperspectral 3D shape and reconstruction of 3D volume density of participating media. - Developed a deep learning tool for classifying digital images of brain tissue slides into benign or malicious tumor tissues. The dataset is from an online library of brain tumor patients.
