About

Since October 2017, I am a CNRS researcher in the SLIDE team at LIG, Grenoble.

Prior to this I was a postdoc at the Max Planck Institute for Software Systems working with Krishna Gummadi. I obtained my PhD in 2014 and my Master degree in 2010 from the Pierre et Marie Curie University in Paris. During my PhD I worked under the supervision of Renata Teixeira. I am originally from Romania, where I obtained an Engineer diploma in Computer Science from Technical University of Cluj-Napoca in 2008.

Research Interests

I am broadly interested in security and privacy aspects of social computing systems (online systems that provide services to people and that have at their core the data produced by them: Twitter, Amazon, Netflix). In my projects I try to understand problems in current systems trough data collection and data mining (measurement and analysis) and propose better solutions (systems design and implementation, data mining algorithms).

My research is motivated by the fact that most people use on a daily basis different social computing systems to perform numerous activities. While the value of these systems is undeniably attested by their global scale adoption, they also bring new challenges and threats for users. My current research projects focus on the following three aspects:

  • Privacy: measure and control the image users leave online (e.g., what data a potential employer could mine about me online?)
  • Transparency: understand the consequences of users's actions on the services they receive (e.g., why am I being targeted with this particular ad?)
  • Trust: estimate the trustworthiness of users and content online (e.g., is this review fake or real?)

Personal

Patrick Loiseau is my wonderful husband. I am very lucky that we can work together and do science over a glass of wine ... after our son goes to bed .
