I am a final-year PhD student in Computer Science at University of Illinois, Urbana Champaign. I am working in the Data Mining Group under Prof. Jiawei Han.
In my research, I develop data-driven, weakly supervised, and scalable techniques for knowledge discovery over massive, complex, and noisy network (graph) data. My interests span graph data mining, network data science, and applied machine learning, with a focus on designing novel graph analysis and deep learning frameworks for the effective construction, modeling, and application of real-world network data, towards tasks like conditional stucture generation, contextualized network embedding, and graph-aided recommendations.
Before joining UIUC, I received my Bachelor of Engineering Degree in Computer Science in 2014, from the Chu Kochen Honors College, Zhejiang University. I was working in the State Key Lab of CAD&CG on machine learning with Prof. Xiaofei He.

Empowered GraphSage for web-scale contextualized recommendation through context-aware aggregation and Hadoop-based stream training on heterogeneous pin-board networks.
Developed a two-step data-driven pipeline of feature generation and metric learning for place embedding to leverage ad-hoc place attributes and noisy training data towards efficient place deduplication.
Constructed the transportation HIN (heterogeneous information network) based on DiDi's travel data and developed a pattern-aware HIN embedding algorithm for passenger experience prediction.
Developed a joint learning framework of user links and attributes for friend recommendation and interest targeting. Implemented a Spark pipeline and scaled it to networks with millions of nodes and billions of edges.
Implemented data extraction and inventory analysis pipeline using flume C++. Implemented an online simulation of ads serving and an offline optimal algorithm based on max flow to analyze the inventory.
