Welcome !

I will graduate in May, 2016. Currently, I am looking for a research career related to database management and data analysis, especially graph databases, temporal databases and time-series databases. If you know such an opportunity, please drop me an email. Thanks!

I'm Haohan Zhu, a PhD student from Data Management Group, Department of Computer Science at Boston University. My advisor is Professor George Kollios.

My research focuses on graph and time-series data management and analysis including indexing methods, query optimization, similarity learning and mining algorithms. Specifically, in my PhD Dissertation, I study temporal graph database systems and analytics. I am also interested in database security and privacy preserving analysis, especially for graph and time-series data.
