Mar 2021: We will present three papers at the Financial Cryptography 2021 conference
Oct 2020: Open positions! Are you interested in doing research on security, privacy and scalability of distributed ledgers (or blockchains)? I am currently looking for talented people to work with me! If you are interested, please do not hesitate to contact me!

I am an assistant professor at the IMDEA Software Institute (Spain) since October 2020. I received my PhD degree in Computer Science from Purdue University (USA) in 2018. Prior to joining the IMDEA Software Institute in October 2020, I held a postdoctoral position at Technical University of Vienna (Austria). During my PhD, I was also a visiting student at Ripple Labs (USA), IBM-Research Zurich (Switzerland). I received my bachelor and master degree from the University of Murcia (Spain). During my master, I was also a visiting student at Philips Research Europe (The Netherlands).
