About

Hello Folks! 😁

📄 Here is my resume if you would like to know more about me.

Now

I am currently a 3rd-year CS PhD candidate at Simon Fraser University, Canada.

Actively looking for internships and collaborations. Please see my research interests below.

Past

I received my bachelor’s degree from the Southern University of Science and Technology (SUSTech, 南方科技大学), China.

I worked as a product manager and a data engineer at Sohu (搜狐), China for three years. I designed and built the engine and data-governance system for the advertising business.

Research Interest

Next-generation materialized view (MV) service with LLM:

Step 1: Before applying LLM, I really want to figure out the performance of existing MV service. Our work [VLDB 2026] shows that MV-driven query rewriting and acceleration is far from being solved, as it is really a matter of “pipeline” (view enumeration, view selection, view-based query rewriting) while previous literatures only carried out single stage evaluation.

Step 2: We have already seen the great potential of using LLM on this task. I am actively incorporating LLM as a semantic reasoner to view enumeration and view-based query rewriting.

AI4DB tasks scheduling on GPU:

Extensive AI4DB tasks require using GPU: Learned optimizers, LLM-powered UDFs, semantic queries etc., These tasks vary a lot on latency sensitivity, parametre size. Finding out an optimal solution to orchestrate them is my focus.

Here are something unique about me:

🗺 Love reading atlas
This should be a niche hobby;
🚲 Love cycling
Frankly, I really DON’T compete the speed with others, since cycling for me is purely a method to slow down, get relaxed and enjoy myself…
✈ Love travelling
Here are the fantastic pictures shot in different travelling destinations.
