Profile
Biography
I had my Bachelor's degree in Applied Mathematics, Fudan University, China and then moved to the UK to pursue my postgraduate studies. I obtained MSc in Operational Research from University of Edinburgh, and did my PhD studies in Optimization in the same school under the supervision of Dr Andreas Grothey. Prior to joining the 糖心Vlog, I worked as a Senior Research Associate in Lancaster University Management School for 1.5 years.
