Experience
• Design and implemented machine learning algorithms to
identify most relevant ads for users.
2015.04 - present
• Research and devleop models for new types of ads product.
Research Intern, IBM T.J. Waston Research Center
summer 2014
• Implemented Hadoop-based algorithms to efficiently extract
discriminative features (e.g. local clustering coefficient) for
bots detection from terabytes of Twitter Streaming API data.
• Developed an integrative web-based system to interactively
rank, label, and detect social bots from millions of candidate users.
Research Assistant, Washington University in St. Louis
2009.08 – 2015.03
• Proposed an innovative link prediction strategy. When applied to
large biological and social networks, it boosted the performance
by ∼ 10% compared to the state-of-the-art algorithms.
• Devised a novel algorithm for domain adaptation problem. When
applied to text document categorization, it not only improved
the prediction accuracy but also provided interpretable semantics
for knowledge discovery.
• Competed in the Yahoo! Learn to Rank Challenge (placed 8th
globally on Set 1 and 7th on Set 2; placed 1st on the evaluation
set of Set 2).
Web Developer, Association of New Canadians
2008 – 2009
• Designed and developed the front-end (using HTML and jQuery)
and the back-end (a CMS using ASP.Net) of a website
www.axiscareers.net from scratch.
Programming Programming languages: C++, C#, Python, Java, Matlab, and R.
Skills
Large-scale data analysis: Open Grid Engine, Hadoop, and Hbase
