Conferences & Presentations:

Prof. David Broniatowski (EMSE) served as a track chair for the SBP-BRIMS 2016 conference, held June 28-30 in Washington, DC.  He also served as session chair for the military and intelligence applications session.

On July 11, Prof. Volker Sorger (ECE) gave an invited talk at the IEEE Summer Topicals Conference, held in Newport Beach, CA.  His work summarized a recent paper submission to Nature Communications that explored fundamental nanophotonics scaling laws.  His team, in collaboration with Prof. Arka Majumdar (University of Washington), explored opto-electronic scaling laws for the first time.  The study was motivated by realizing that in electronics (i.e. transistors) “smaller is better”; hence, the question was how opto-electonic devices perform (speed, power, footprint) when scaled down into the nano-regime.  The talk was part of a special symposium focusing on optical computing and optical data processing.  Separately, Prof. Sorger gave an invited talk at the AFOSR Annual Young Investigator Award Winner meeting, held June 20 in Arlington, VA.  Here he showed the recent progress of his lab in regards to: a) atto-joule per bit efficient optoelectronics; b) optical information processing using nanophotonics; and c) SMART IoT (Internet-of-Things) devices.

On June 29, Prof. Timothy Wood (CS) gave an invited talk and led a discussion section on network function virtualization at the 9th Cloud Control Workshop, held in Stockholm, Sweden.
