I am currently a smart cities postdoc at New York University, supervised by Prof. Juliana Freire and Prof. Daniel B. Neill. I got my Ph.D. from RMIT University, Australia in 2019, supervised by Dr. Zhifeng Bao, A/Prof. J. Shane Culpepper, and Prof. Timos Sellis. My interests are mainly on spatial database, especially trajectory data management. I have published several full research papers on top venues in database and information systems as the first author, such as PVLDB, SIGIR, WSDM, ICDE, TKDE.
