|I started my PhD in Transportation Systems Engineering in November 2016, under the MIT-Portugal Program. I completed my Masters in Transportation Engineering from the Indian Institute of Technology (IIT), Madras. Prior to joining the PhD program, I was working at the Singapore-MIT Alliance for Research and Technology (SMART).
I have been working on analysing what is the suitable approach for measuring Qualitative Data. I use automated text analysis for the extraction of information from open-ended questions. These are used to measure the intention to use Shared Autonomous Mobility Services. This was carried out using online questionnaires launched in Denmark and India.
Vishnu also participated in a Short-term Scientific Mission (STSM) under the EU Cost Action TU1305, at Technical University of Denmark (DTU).
