In this interview series, we're meeting some of the AAAI/SIGAI Doctoral Consortium participants to find out more about their research. The Doctoral Consortium provides an opportunity for a group of PhD students to discuss and explore their research interests and career objectives in an interdisciplinary workshop together with a panel of established researchers. In this latest interview, we hear from Sukanya Mandal about her PhD so far. I am Sukanya Mandal, a PhD student at Dublin City University in Dublin, Ireland. My research focuses on developing "A privacy-preserving federated learning (PPFL)-based cognitive digital twin (CDT) framework for smart cities".
