I am a first year PhD student SPriTELab in The University of Texas at San Antonio. I am currently investigating on the feasibility of inferring private handwritten information using wearable devices. My research interests lie in security and privacy in wearable systems, privacy in genomic era and non-monetary uses of blockchain technology.
