I am currently a Lecturer (Assistant Professor) at the University of Leicester. I am also an affiliated/visiting researcher at the Department of Computer Science and Technology, University of Cambridge. I was a Research Associate worked with Prof. Hatice Gunes from 09/2020 at the University of Cambridge. Prior to that, I obtained my PhD degree at the University of Nottingham, funded by Horizon CDT, under Prof Michel Valstar and Prof Alan Johnston's supervision.


Siyang's research interests include:

Affective Computing (Automatic mental health and personality analysis, Multiple Appropriate Facial Reaction Generation)

Human-computer Interaction

Computer Vision

Machine Learning

Graph Representation Learning

Grand Challenge and Workshop Organization:

I have been served as the chair for several international affective computing and HCI Challenges/workshops including:

Multiple Appropriate Facial Reaction Generation Challenge: IEEE FG REACT 2024  and ACM MM REACT 2023.

Pain Detection Competition at IEEE EmoPain 2020

AI Emotion and Depression Detection Competition at ACM MM AVEC 2019.

HCI: AHRI 2022 and AHRI 2023

I have also contributed as a reviewer for several top-tier international journals and conferences, including IEEE PAMI, IJCV, IEEE TAFFC, IEEE TIP, AAAI, IJCAI, CVPR, ICCV, ACM MM, and others.
