Hi there! I am an associate professor at NTNU. Previously, I was a part-time employee at Intel. Before that, I was a postdoc at the ISG group at RHUL, working with Martin Albrecht and Rachel Player. Before that, I worked as a Research Scientist at Intel AI Research in San Diego. I completed my PhD at Bristol University, under the supervision of Nigel Smart. I am interested in all aspects of fully homomorphic encryption and more broadly, computing on encrypted data, privacy-preserving machine learning, lattice-based and post-quantum cryptography. My research has been in part sponsored by Intel. You can contact me at anamaria.costache1992@gmail.com .
I completed my undergraduate and Masters degree at Warwick University, where I studied number theory with a focus on algebraic number theory. My final year dissertation was on Brauer Groups.
I am currently on sabbatical. I'm very happy to be spending some time working with Flashbots. I was very fortunate to be a long-term visitor in the ECO Team of the LIRMM research institute in Montpellier, France during my last sabbatical. Thanks to the entire team for welcoming me so kindly!
Away from work, I enjoy bouldering, reading and travelling.
