Bio

(short) Andersen joined ECS-UoS-UK in 2023. He did his postdoc in Canada, PhD in Belgium.

(long) Andersen Ang is a lecturer in the Electronics and Computer Science at the University of Southampton, UK. He was a Fields postdoctoral fellow at the University of Waterloo, Canada, working with Stephen Vavasis and Hans De Sterck. He completed his PhD in applied mathematics (2020) at the University of Mons, Belgium, under the supervision of Nicolas Gillis. He got a BEng in Electronic and Communication Engineering (2014) and an MPhil in Biomedical Engineering (2016) from the University of Hong Kong. He works on optimization and matrix-tensor factorizations.

Previously ...

in Waterloo, Canada
In his postdoctoral period at the University of Waterloo, Andersen Ang was a Fields postdoctoral fellow in the Department of Combinatorics and Optimization. He worked under the guidance of Stephen Vavasis and Hans De Sterck. He taught two full courses in applied linear programming.
His research focused on integrating multi-grid methods with nonsmooth optimization.

in UMONS, Belgium
He pursued his PhD at the University of Mons in Belgium, under the supervision of
Nicolas Gillis. His PhD jury: Thierry Dutoit and Xavier Siebert from UMONS, Laurent Jacques and Francois Glineur from UCLouvain and Lieven De Lathauwer from KULeuven, all Belgian.

!

in HKU, Hong Kong
At HKU, He received a few academic awards, worked with many departments, served as the head teaching assistant, and taught numerous undergraduate courses. His excellence in teaching was recognized with teaching awards in consecutive years (2015 and 2016). He also contributed to the Technology-Enriched Learning Initiative by producing a MOOC (Massive Open Online Course) titled “HKU03x: Humanity and Nature in Chinese Thought” and a SPOC (Small Private Online Course) titled “CCST9003: Everyday Computing and the Internet.” Additionally, he published an IEEE paper on teaching and evaluation.
