Diego F. Aranha

Associate Professor, Aarhus University

I am an Associate Professor in the Department of Computer Science at Aarhus University, Denmark, where I conduct research in cryptographic engineering and security of real-world systems. I also lead the Cybersecurity Work Package at DIGIT and contribute to COBRA as Principal Investigator.

I have received two Google Latin America Research Awards for privacy, and the MIT TechReview’s Innovators Under 35 Brazil Award for my work in electronic voting.
