Current & Future Research

My research interests are in the area of networked systems, with an emphasis on wireless systems. Cheap, fast and portable computing devices with ubiquitous wireless connectivity have the potential to revolutionize the personal computing landscape, creating an opportunity to design an unprecedented array of new applications and services. Standing in the way of this vision however, are several challenges across the entire spectrum of the system architecture. These range from the unpredictable wireless medium and interference at the lower layers, to limited throughput, unreliability and mobility at the network layer, and to complex, unsecure and closed software substrates at the application layer. Typical approaches to these problems have been piecemeal and isolated, leading to partial solutions at different layers which when put together introduce more complexity, inhibit extensibility, and often limit performance. My approach looks at the entire system architecture in a holistic fashion. I develop interdisciplinary solutions that encompass signal processing schemes, coding and decoding techniques, network protocols and software substrates.
