I do research on computer security, privacy, and Internet measurements. I am also interested in understanding the impact of technology on society. You can find a complete list of my research publications Google Scholar profile.

My most recent research efforts have focused on developing tools and data-based evidence to study the prevalence of unwanted and harmful software in the Android ecosystem. Our findings and research outputs can be found in the Android Observatory, a joint project with colleagues from the Internet Analytics Group at IMDEA Networks Institute and other researchers abroad.

I also have a keen interest in malware and systems security topics, especially for Unix-like systems.

I am lucky to have been the recipient of several prizes and awards for my work. These include:

I am open sourcing all my teaching materials, but it will take me a while to complete the process.
