About me

I am the Manager and Chief researcher of the Security Group of NEC Labs in Germany. I joined NEC Labs in April 2012. Before then, I was working as a postdoctoral researcher in the Institute of Information Security of ETH Zurich, Switzerland. I hold a Master of Science degree in Information Networking from Carnegie Mellon University (CMU), and a PhD degree in Computer Science from ETH Zurich.

I am interested in all aspects of security and privacy with a focus on cloud security, IoT security, network security, and Blockchain security.

My full list of publications is available here (by date) and here (by topic).


My Book on Bitcoin and Blockchain Security

This comprehensive new resource presents a thorough overview and analysis of the security and privacy provisions of Bitcoin and its underlying blockchain clients. This book goes beyond the analysis of reported vulnerabilities of Bitcoin, evaluating a number of countermeasures to deter threats on the system. Readers are given concrete solutions and recommendations on the best practices to use when relying on Bitcoin as a payment method.This resource provides a clear explanation of assumptions governing the security of Bitcoin, including the scalability measures adopted in Bitcoin, privacy for clients, and the proper means of securing Bitcoin wallets. Readers learn how the security and privacy provisions of other blockchain technologies compare to Bitcoin and the security lessons learned after extensive research of Bitcoin since the inception of the currency.
