Short Bio

Yuchen is an Assistant Professor at the School of Computing and Information System (SCIS) in the Singapore Management University (SMU). Before joining SMU, he was a research fellow at the National University of Singapore (NUS). He received his Ph.D degree in computer science from NUS in 2017. His major research interests are social analytics and high performance graph mining. Besides, he also interested in fintech with large language models (LLMs).

HOT We are actively looking for talented and highly motivated Ph.D. students to work on large scale graph learning and fintech with LLMs. If you are interested, please find information about the SIS PhD Program and send an email to me (full scholarship and monthly stipends available).

    Large Scale Graph Processing on GPUs.

    Graphs are powerful structures to represent complex dependencies in the data. Large scale graph processing remains a fundamental challenge, due to its compute-intensive as well as data-intensive nature. There are emerging interests in adopting massively parallel GPUs to speedup graph processing. Nevertheless, existing GPU solutions focus on static, homogeneous graphs and simple graph algorithms, e.g., BFS, shortest path, connected components and etc. In this project, we explore using GPUs for more complex processing tasks (e.g., motif discovery and deep learning on graphs), with emphasis on heterogeneous and dynamic graphs.

    Fact Checking on Social Media Streams.

    Massive amount of information has been continuously generated on social media streams. Misinformation posted in social media messages leads to undesirable consequences and can be very difficult to correct since people make casual inferences based on available information about a given event or outcome. A computational fact-checking engine is much needed to identify false statements. Existing approaches either uses knowledge graph to semantically fact-check statements but suffers from performance issue, or completely ignores the semantic meaning and solely focus on viral patterns to determine problematic statements. In this project, we are planning to develop an efficient engine on top of the knowledge graph to fact-check the massive social media streams.
