Her research focuses on security, applied cryptography, and algorithms. She is best known for her work identifying widespread entropy problems in cryptographic keys on the Internet (2012 Usenix Security best paper award), and developing the "cold boot" attack against disk encryption systems (2008 Usenix Security best student paper award). Previously, she was an NSF Mathematical Sciences Postdoctoral Fellow at UC San Diego and a visiting researcher at Microsoft Research New England. She received her Ph.D. in computer science in 2011 from Princeton and a B.S. in electrical engineering and computer science in 2004 from UC Berkeley.
