ProjecToR is a novel, free-space optics based approach for building data center interconnects. It uses a digital micromirror device (DMD) and mirror assembly combination as a transmitter and a photodetector on top of the rack as a receiver. Our approach…
I’m a postdoc at Microsoft Research working with the Theory Group and the Adaptive Systems and Interaction Group. I received my PhD in EECS from UC Berkeley in 2014 and my SB from MIT in 2007. I’m interested in many things including but not limited to information theory, control, wireless communication, robotics and autonomous navigation, and crowdsourcing.
I received my PhD in Electrical Engineering and Computer Science from UC Berkeley, where my advisor was Anant Sahai. I am interested in information and control theory, wireless communications, crowdsourcing, brain-machine interfaces, EECS education and many other things.

- As a graduate student I was heavily involved with the Electrical Engineering Graduate Student Association (EEGSA) and Women in Computer Science and Engineering (WICSE) at Berkeley. I also co-founded EECSPeers, a peer-support community. Working with these organizations was one of the highlights of my graduate experience — do get involved if you can.
- If you are an undergrad in EECS at Berkeley (or anywhere else), get involved in research. Present your work at the Undergraduate Research Symposium!
- From January to June 2009, I was one of the first instructors for computer science in Accra, Ghana at the Meltwater Entreprenurial School of Technology, where I designed and taught introductory computer science classes.
