Background & Biography
She previously worked as a staff research scientist at Google and as an IC3 associate director. She remains an IC3 faculty member. Her academic contact address is in London.
Notable Contributions
Her selected publications include Bitcoin transaction analysis, cryptocurrency privacy and zero-knowledge proofs. More recent entries address machine-learning security and privacy.
Why Katharos.ai Is Following Them
Katharos.ai follows her security research. Coverage should distinguish what an analysis demonstrates from what its methods cannot establish. Privacy claims need particular care: the presence of a cryptographic mechanism does not by itself prove that every implementation, user or operational practice is protected.
Areas to Follow
Follow published research and explicitly announced professional changes. Assess the threat model and evidence behind each result, distinguish academic proposals from deployed protections, and avoid describing historical leadership roles as current. A publication record should not be treated as an endorsement of a cryptocurrency, service or commercial security claim.
Reporting Scope
Country refers to her stated academic affiliation and contact location, not citizenship or private residence. This profile does not imply that she is working full-time at the university or soliciting new students. Inclusion is not endorsement or investment advice.
