< Ghazaleh Beigi

I'm a fifth year Ph.D. Candidate at Data Mining and Machine Learning Lab, Arizona State University under supervision of Professor Huan Liu. My research is focused on leveraging machine learning/data mining techniques for discovering, understanding and modeling implicit signals in online users behavior.

Before joining ASU as a Ph.D. student in Fall 2014, I have earned my Bachelor's and Master's degree from the Sharif University of Technology.

My research interests include:

  • User privacy protection
  • Signed network analysis
  • Trust and distrust prediction
  • Recommendation Systems
  • Sentiment analysis
  • User behavior modeling
  • Machine learning and data mining

My recent research on web browsing history anonymization which is accepted in the WSDM 2019, was featured in the news: The data defenders.

We also prepared a comprehensive survey on privacy in social media. It could be found here.

This is also my CV .
