    Research Assistant

    ◦ IARPA-BRIAR: Developing face recognition systems for the IARPA-BRIAR program. Developing algorithms to
    recognize faces from low resolution images, by improving state-of-the-art face recognition pipeline such as AdaFace
    using deep metric learning loss formulation. Tech Stack: PyTorch, CNN, ProxyNCA
    ◦ Generating Clinical Biomarker Profiles: Working with the Department of Pharmaceutical Sciences, University at
    Buffalo, to model clinical biomarker profiles of under-represented groups. Developed conditional GAN to learn a
    panel of 16 diabetes-relevant biomarkers from the National Health and Nutrition Examination Survey (paper). Tech
    Stack: Python, GAN, VAE
