Aruna Balasubramanian's work incorporates elements of both networking and systems in the context of mobile devices. The goal of her work is to design mobile protocols/systems that radically improve performance. Current mobile system designs make assumptions, that while true for the wired environment, are not valid for the mobile environment. Instead, she wants to re-architect mobile systems to better support current and next-generation applications. Dr. Balasubramanian's recent projects include MobileHub (reduces energy consumption of always-on sensing applications by leveraging heterogenous hardware), WProf (a tool that identifies the bottlenecks during page load), and FindAll (makes mobile applications less reliant on the cloud by building a local search engine on phones, that lets users search locally).
