Research Statement My research focuses on vector databases, approximate nearest neighbor search (ANNS), and data management systems, with an emphasis on efficient indexing, query optimization, and scalable similarity search. In addition, I'm quite interested in solving algorithm problems from codeforces.
古人之观于天地、山川、草木、虫鱼、鸟兽，往往有得，以其求思之深而无不在也。
夫夷以近，则游者众；险以远，则至者少。 而世之奇伟、瑰怪，非常之观，常在于险远，而人之所罕至焉，故非有志者不能至也。 有志矣，不随以止也，然力不足者，亦不能至也。 有志与力，而又不随以怠，至于幽暗昏惑而无物以相之，亦不能至也。 然力足以至焉，于人为可讥，而在己为有悔；尽吾志也而不能至者，可以无悔矣，其孰能讥之乎？ 此余之所得也！
—— 王安石《游褒禅山记》
