Hi! I am Yan, a final-year Doctoral Candidate in Computer Science at Aalto University, Finland. I am supervised by Prof. Mikko Kivelä and advised by Dr. Barbara Keller. I expect to graduate by October 2025 and I am now actively looking for postdoctoral positions.

I am a computational social scientist who aims to conduct solid research that bridges computer science and social science. My main interest lies in understanding the organic socio-psychological processes underlying negative phenomena in online systems, such as opinion polarization, political (anti-)fandom, and toxic language. I use various computational tools in natural language processing and network analysis to address my research questions. My work has been published in venues including CSCW, ICWSM, and EPJ Data Science.

Please see Resume for a complete list of my experience, and Projects for an introduction of my main research projects. If you are interested, some of my photography, design, and calligraphy works can be found in Gallery.
