About Me

_images/pic2.png

I am a PhD candidate in the deparments of Electrical and Computer Engineering at Carnegie Mellon University, PA, and at Instituto Superior Técnico, Technical University of Lisbon, Portugal. I am also affiliated with the Institute for Systems and Robotics at Lisbon. My research interests include distributed optimization, distributed control, and sensor networks.

My advisors are:

See this link for an explanation of D-ADMM, an algorithm at the core of my thesis. The link also contains some Matlab code.
