Sachit Mahajan was a Postdoctoral Research Associate on the AirKit Project of Citizen Sense in the Department of Sociology at Cambridge. His research interests lie in the area of Internet of Things and air quality sensing, especially focusing on participatory sensing systems that emphasize collaboration with citizens and local communities. He is also interested in developing machine learning algorithms and tools for spatio-temporal data analysis of IoT systems, and designing applications that can assist people in their everyday lives.

He has been actively involved in the Airbox project in Taiwan that enables PM2.5 monitoring at a finer spatio-temporal granularity and encourages citizen engagement by having an open-source framework. In the past, he also worked on the iSCAPE (Improving the Smart Control of Air Pollution in Europe) project (Horizon 2020) at the University of Surrey, UK. His responsibilities included leading field experimental campaigns for evaluation of air pollution control interventions and assessing air pollution sensor technologies and citizen involvement by organizing citizen science workshops.
