About Me

Hi there! I’m a Ph.D. student in Computer Science at Carnegie Mellon University advised by Prof. Christos Faloutsos. My work is supported by the NSF GRFP. My work is in the intersection of data mining and visualization for social good projects. More specifically, I’ve worked on finding human sex trafficking online and reducing entry into homelessness through better distribution of rental assistance. You can find my CV here.
