Welcome to UbiSys Research Group!

The Ubiquitous Systems (UbiSys) research lab, led by Dr. Suchetana Chakraborty, focuses on many areas of ubiquitous computing including novel user interface technology, health sensing, activity recognition, low-power sensing, and energy sensing by applying expertise in sensing, signal processing, embedded systems, circuits, and human-computer interaction.

The UbiSys lab consists of an interdisciplinary team of investigators that tackle challenging research problems both from building the enabling hardware and software systems to the deployment and evaluation of these technologies in real-world settings, especially around health. We collaborate very closely with IIT Professors in the Department of Computer Science & Engineering, and the Interdisciplinary department at the Indian Institute of Technology Jodhpur. In addition, we have close collaborations with many other institutions such as UMBC, IIT Kharagpur, IIT Bombay.
