About me

I am a PhD Student in the Networks and Operating Systems Research Group, under the supervision of Professor Cecilia Mascolo. I am funded by Microsoft Research through their PhD Scholarship Programme. I am a member of Corpus Christi College.

My research lies at the intersection of mobile sensing, ubiquitous computing and machine learning. In particular, I am interested in how context monitoring and sensor-based applications can be made to co-exist on co-processor enabled mobile devices in an energy friendly manner. Low power co-processors such as the Qualcomm Hexagon DSP are increasingly becoming available in high-end smartphones and wearables with the aim to lower the energy barrier for a variety of application domains including multimedia and sensor processing. In my recent research, I investigate how these new computational elements can be fully leveraged to maximize the energy efficiency of multiple interacting microphone-based (e.g., speech recognition) or accelerometer-based (e.g, activity recognition) mobile applications.
