A portrait of me with a smile :)

I'm a third-year PhD student at the School of Information Studies (iSchool) of Syracuse University working on data-driven privacy and security systems.


about my research

My research involves the design and evaluation of user-facing, data-driven systems aimed at increasing algorithmic transparency and preventing privacy violations. I'm particularly interested in understanding how such systems can enable users to make sense of pervasive technologies in the age of ubiquitous computing, inferences, and automated decision-making.

My work mostly lies at the intersection of human–computer interaction, ubiquitous computing, and machine learning, but I have also worked on authentication, accessibility, and people-nearby applications. My advisor is Prof. Yang Wang.

about me

I enjoy breaking building things. In the past, I have built applications in several platforms, such as mobile apps and virtual reality systems. I have also organized a civic hackathon and competed at many web design/development contests. Recently, I joined Figure Eight as a research intern (Summer 2018) to advance the synergy of machine learning and large-scale human intelligence.

When my masters allow it, I'm out for a run or a hike in beautiful Upstate New York. I love traveling and learning about different cultures. I also enjoy sci-fi movies and books, geometric abstraction, and games (tabletop, PC, and retro).
