Azam Ali is a PhD Student at the Institute for Transport Studies, University of Leeds supervised by Charisma Choudhury, Stephane Hess, and Ed Manley. His PhD research is related to addressing the challenges in utilising passively collected sources such as smartphone-based travel surveys to develop travel demand models. His research interests lie in the use of discrete choice models and machine learning techniques to understand and model travel behaviour. Prior to starting his PhD, Azam carried out a Masters in Transport Planning and Engineering and Masters in Social Research at the University of Leeds. He has previously compared and contrasted discrete choice models and machine learning techniques to model vehicle ownership decisions and time-use. Azam is also undertaking an enrichment studentship at the Alan Turing Institute, where he plans to work with passively collected data sources to understand travel behaviour.
