1 Eric J. Rozner Burnet Rd Austin, TX Research Interests Computer systems in general, with an emphasis on wireless networking and mobile applications. Specifically, my research focuses on wireless network management by designing, building, and evaluating practical wireless systems to manage loss, interference, capacity, co-existence, and energy in a variety of wireless technologies, such as Wi-Fi, Cellular, and next-generation White Space networks. My interests span the entire length of mobility networks, from mobile applications on user equipment, to radio-access techniques, to rethinking the architecture of the core cellular network. In general, I enjoy implementing my ideas on real testbeds in order to make my research practical and to also gain an in-depth understanding of the underlying technical details of a system.

Projects include line-rate sampling and traffic engineering, distributed host-based load balancing and SDN debugging tools. Other projects focus on mobility. AT&T Labs - Research Florham Park, NJ, USA Senior Member of the Technical Staff December 2011 to May 2013 Cellular network management, with a focus on planning heterogenous network deployments. Specifically, building a rapid channel-sounding system on software-defined radios to quickly and cheaply determine coverage areas of potential small cell access nodes (cell towers characterized by limited transmission ranges) in future LTE networks. I also analyzed social media data to help determine which small cell locations effectively offload capacity. Published one paper and submitted one patent.

2 Professor Lili Qiu. Facilitated wireless network management through combatting loss, mitigating and modeling interference, and improving performance in wireless networks. My graduate studies took a systems-building approach to network management, and I developed wireless technologies on a variety of platforms using a diverse set of tools. For instance, I implemented routing protocols in Windows and the Click router, modified wireless drivers and access point software, utilized software-defined radios, and ran traces and monitored energy on smart-phones. Published two journal papers, seven conference papers, and four workshop papers. All but one feature testbed prototypes and evaluation.
