My research is in computer security and privacy. I have a special interest in data and machine learning privacy.

This year, I am involved in the following events:

• ACM Conference on Computer and Communications Security (CCS) 2017
• International Workshop on Obfuscation: Science, Technology, and Theory 2017
• Network and Distributed System Security Symposium (NDSS) 2017
• Privacy Enhancing Technologies (PETS) 2017
• IEEE European Symposium on Security and Privacy (Euro S&P) 2017
