I am a postdoc at Howard Hughes Research Laboratories in Malibu, CA. My work focuses on social media data mining for early detection of newsworthy events, most recent paper: http://arxiv.org/abs/1404.7152.
In 2012 I finished a mathematics PhD at UCLA. My graduate work involved sparsity promoting optimization in quantum mechanical signal processing. You can find me elsewhere on the web: scholar.google.com
