Alishah is an assistant professor at Baruch College, with a research focus in applied cryptography and privacy. He received his Ph.D. from Johns Hopkins under the guidance of Prof. Matthew Green and most recently was a postdoc at Boston University working with Prof. Mayank Varia. His research is centered on making privacy-preserving protocols practical by identifying mismatches in modeling or deployment gaps. He is also actively involved in organizing the Re-Imagining Cryptography and Privacy (ReCAP) Workshop, dedicated to foregrounding the privacy and technology needs of marginalized communities.
