Jacques Stern has advised numerous researchers through collaborations with scholars like David Pointcheval, Antoine Joux, and Guillaume Poupard. His leadership roles at ENS, ANR, and ARCEP reflect his influence on national research and cybersecurity policy. He has contributed to cryptographic standards, including evaluations of AES candidates.

As Director of the ENS Computer Science Laboratory (1996–2007), he fostered interdisciplinary research. His later advisory roles (e.g., ARCEP, 2012–) continue to shape electronic communications regulation.
