Giuseppe is a Professor, Eminent Scholar in the Cybersecurity and CCI Faculty Fellow in the Department of Computer Science and the Department of Cyber Security Engineering at George Mason University. He has advanced many areas of research, including proxy re-encryption, anonymous communication, two-party computation, secure storage, and provable data possession.

His current work includes privacy-preserving machine learning and decentralised secure computing based on blockchain technology. He received the NSF CAREER Award for his research on privacy and security, and the Google Faculty Research Award, the IBM Faculty Award, and the IEEE CISTC Technical Recognition Award for his research on cloud security.

Giuseppe was a researcher at IBM Zurich Research lab (Switzerland) and a scientist at the Information Sciences Institute of the University of Southern California (USA), and worked briefly as a visiting professor at Microsoft in Redmond (USA).

He was the Farber Endowed Chair in Computer Science and Department Chair at Stevens Institute of Technology. He previously worked with Sapienza University of Rome (Italy) and was an Associate Professor at Johns Hopkins University (USA). Giuseppe is also one of the JHU Information Security Institute's founders.

Joos is a Professor Emeritus with the Department of Electrical Engineering at the Catholic University of Leuven, Belgium. He is one of the most impactful researchers in Computer Science in the World, including in areas of cryptography, secure data communications, data mining and complex systems. His work has led to many areas of impact, including supervising the creators of the Advanced Encryption Standard. He has also worked to simplify the computational complexity of support vector machines, and which involved using a least-squares approach for learning-based classifiers. He has also enhanced the theory behind singular-value decomposition by extending it to multilinear dimensions, which has addressed complex data-mining challenges. Joos is also an IEEE Life Fellow and served as the President of the Royal Flemish Academy of Belgium KVAB. He also co-wrote the book defining "The Invisible Power of Mathematics".

Jens is a Chief Scientist at Nexus, and works in many areas of cryptography including in pairing-based cryptography and Zero-knowledge Proofs (ZKPs). He was previously a Professor of Cryptology at University College, London, and as the Director of Research at DFINITY. In 2016, he published a classic paper of "On the size of pairing-based non-interactive arguments", and which defines a Zero Knowledge Proof based on pairing-based cryptography. This is now known as Groth16, and is used in many applications, including with Zcash and Tornado Cash. In 2021, he won an IACR Test of Time award for the "Simulation-sound NIZK proofs for a practical language and constant size group signature". Then, in 2023, he won the IACR Test of Time Award with Amit Sahai for the 2018 paper on "Efficient Non-Interactive Proof Systems for Bilinear Groups".
