About Me
Currently, I am a researcher affiliated with the ECE department of National University of Singapore. I obtained my Ph.D. from the ECE Department of National University of Singapore in June 2023. My Ph.D. supervisors were Prof. Haizhou Li, Prof. Luis Fernando D'Haro, and Prof. Xinchao Wang. I was also an NUS-Robert Bosch (SEA) IPP student (2019 - 2022) and Dr. Thomas Friedrichs was my supervisor in Robert Bosch (SEA). My research interests include Automatic Dialogue Evaluation, Dialogue Systems, and Natural Language Processing in general. Previously, I obtained my double degree in business and Computer Engineering from Nanyang Technological University.
