Thea Ullegård Kjeldsmark

I am a PhD Computer Science student at the University of California, Irvine. My research focuses on security and privacy for emerging technologies.

I hold an MS in Computer Science from UC Irvine and a BSc in Software Development from the IT University of Copenhagen. During my masters, I spent a summer as a research fellow at ETH Zürich in the Advanced Software Technologies Lab.

Outside academics, I have interned as a software engineer at J.P. Morgan and Microsoft. I have also had the opportunity to live in seven different countries: Denmark, USA, South Korea, Scotland (UK), Ireland, Egypt, and Switzerland.
