Alumni

Xiaojia Rao
Xiaojia was a PhD student at the Department of Computing at Imperial, under the supervision of Professor Philippa Gardner. He completed his PhD in 2025. Xiaojia studied for his BA and MMath degree at the University of Cambridge and then moved to Imperial College London in 2020 to join the MSc in Advanced Computing. His Master’s thesis was on a verified model of WebAssembly in Coq called WasmCert-Coq.

Sacha Ayoun
Sacha was a PhD student at the Department of Computing at Imperial, under the supervision of Professor Philippa Gardner. He completed his PhD in 2025. As an undergraduate, Sacha worked at the French Alternative and Atomic Energy Commission (CEA) as a researcher-engineer intern in 2017. His goal was to improve the Frame-C abstract interpreter to better handle file descriptors. In 2018 he completed his Supelec Engineer Diploma at CentraleSupelec as well as his MSc in Advanced Computing at Imperial.

Gabriela Sampaio
Gabriela was a PhD student at the Department of Computing at Imperial, under the supervision of Professor Philippa Gardner. She completed her BSc and MSc at Federal University of Pernambuco (UFPE, Brazil), spending a year abroad at the University of Kent, working on the Erlang refactoring project (Wrangler). In 2022, Gabriela defended her PhD thesis, A Trusted Infrastructure for Symbolic Analysis of Event based Web APIS, and took up a position at Meta (formerly Facebook).

Julian Sutherland
Julian defended his PhD thesis, Compositional termination verification for fine-grained concurrency, in 2022. Julian is currently a Formal Verification Engineer at Nethermind, a blockchain company working on Ethereum.

Shale Xiong
Shale was a PhD student with the group. Shale defended his thesis: Parametric Operational Semantics for Consistency Models in February 2020 and he is currently working for Arm Research, Cambridge, as a Research Engineer in their Security group.

Pedro da Rocha Pinto
Pedro was a PhD student and a Post Doc in the group, working on developing logics for verification of fine-grained concurrent programs. Pedro defended his PhD thesis, Reasoning with Time and Data Abstractions in January 2017. He is currently working for Collage.com, Inc. a Michigan-based photo products e-commerce company.

Thomas Wood
Thomas was a PhD student with the group, working on software automated testing, verification and reasoning techniques and theory.

Daiva Naudžiūnienė
Daiva defended her PhD on An Infrastructure for Tractable Verification of JavaScript Programs in March 2018. Since 2017, Daiva has been working as a Research Scientist at Facebook as part of the engineering team led by Peter O’Hearn.

Azalea Raad
Azalea was a PhD student with the group, defending her thesis on Abstraction, Refinement and Concurrent Reasoning in February 2017. She then moved to the Max Planck Institute for Software Systems (Kaiserslautern) working a postdoctoral researcher with Derek Dreyer and Viktor Vafeiadis on the ERC RustBelt project. In 2020, Azalea joined the faculty at Imperial College London as a lecturer.

Gian Ntzik
Gian was a PhD student and Post Doc with the group. Gian defended his thesis Reasoning about POSIX File Systems in February 2017 and is currently working for Amadeus in systems development and research.

Petar Maksimović
Petar was a Research Fellow with the group and the Academic Program Manager for the Research Institute on Verified Trustworthy Software Systems (VeTSS) until his move to industry in 2022. Petar is also a Research Assistant Professor at the Mathematical Institute of the Serbian Academy of Sciences and Arts, Belgrade.

Emanuele D'Osualdo
Emanuele joined the group as a Marie-Curie Fellow in 2018 with his project “Verification through Security and Progress Abstractions” (VeSPA). In 2020 he moved to the Max Planck Institute for Software Systems (MPI-SWS), Germany, to work on the verification of concurrent programs with the IRIS program logic project.

Martin Bodin
Martin joined the group as a Research Associate in 2018. His work focused on a formalism called skeletons to represent the semantics of real-world programming languages (JavaScript, R, etc.) He also was part of the team working on the formalisation of WebAssembly/Wasm in Coq. In 2020 Martin was appointed CRCN (chargé de recherche de classe normale) in the Sound Programming of Adaptive Dependable Embedded Systems (Spades) group at Inria Grenoble-Rhône-Alpes Research Centre, France.

José Fragoso Santos
José joined the group as a Research Associate in 2015, working on program analysis and JavaScript Verification. He is now an Assistant Professor at the Instituto Superior Técnico, Lisbon, Portugal.

Andrea Cerone
Andrea joined the group as a Research Associate in 2016. He left Imperial College in 2019, to move to industry. He is still an active researcher, continuing his work on the mathematical foundations of geo-replicated and distributed systems, with a particular emphasis to databases, and its applications for overcoming practical challenges in such systems. His latest publication is Data Consistency in Transactional Storage Systems: A Centralised Semantics at ECOOP 2020
