I am an assistant professor at Aalto University, Finland. I am fortunate to have gained extensive international research experience across leading institutions throughout my academic career. Previously, I was a postdoc at Nanyang Technological University, working with Prof. Yang Liu, and at the University of Melbourne, working with Prof. Bach Le. I obtained my Ph.D. degree from the University of Luxembourg, where I also served as a postdoc under the supervision of Prof. Tegawendé F. Bissyandé and Prof. Jacques Klein. During my post in Luxembourg, I was a visiting scholar with Prof. Claire Le Goues at Carnegie Mellon University and a visiting Ph.D. student with Prof. Shing-Chi Cheung at Hong Kong University of Science and Technology. Before returning to academia, I worked as a machine learning researcher at high-tech giants Tencent and Didi.

Visitors are always welcome.
