Mengzhao Wang

PhD candidate

Zhejiang University

Overview

I am currently working toward the PhD degree in the College of Computer Science and Technology, Zhejiang University, China. My research interests include vector similarity search, hybrid query and multimodal search. I have published three research papers in these areas, with two in VLDB and KBS. In addition, I applied for four invention patents, hosted three projects, and participated in several projects.

Currently, I focus on the following research topics:

Graph-Based Approximate Nearest Neighbor Search Algorithm
DRAM&SSD-Driven Approximate Nearest Neighbor Search
Hybrid Queries with Structured and Unstructured Constraints
Mutimodal Search
