"I mentored David at DOCOMO Innovations, Palo Alto, CA, between May-September, 2011, where he was a visiting postdoctoral researcher in leave from Kings College London. He worked on mobility and interference management for small cell networks. He was one of the most focused, productive, and easy-to-collaborate-with researchers that I have ever worked. He would come up with innovative approaches and new angles to tackle a challenging research problem, simulate and/or analyze the approach in practical conditions (he had a very good handle on ray tracing simulations and 3GPP specifications at that time which were difficult to come by), and always come up with interesting and insightful results. We had several highly cited papers published from the work he carried out during his visit, but the one that I liked the most was "On the expanded region of picocells in heterogeneous networks" which got published at IEEE JSTSP in 2012 which shows both the depth and breadth of David's technical skills right after finishing his PhD. I learned a lot myself from David, both technically and attitude-wise, and I would not hesitate to do a PhD with him in grad school."
