About Me

Hi there! Thanks for taking the time to visit. I am currently a postdoctoral fellow at the Systopia Lab at UBC, Vancouver.

I am interested in making systems more secure while maintaining high performance. My research primarily explores hardware-based security mechanisms, such as trusted execution environments (TEEs), that enable secure processing of plaintext data, while also investigating cryptographic approaches, such as homomorphic encryption (HE) and multi-party computation (MPC), that enable computation on encrypted data. I leverage both hardware- (such as in-memory processing) and software-based techniques to improve the performance, scalability, and practicality of these security solutions. Simply put, my research balances robust security with high performance :star_struck:.

Prior to UBC, I was a postdoctoral researcher at the University of Neuchâtel (UniNE), Switzerland, where I equally completed my PhD in Computer Science on Enhancing Security and Performance in Trusted Execution Environments in February 2024, under the supervision of Prof. Pascal Felber, Dr. Valerio Schiavoni, and Prof. Alain Tchana.

In my free time I am an electronics hobbyist who loves tinkering with microcontrollers to build interesting automation projects; I recently got a 3D-printer, and I’ve been building some fun toy robots. When I’ve got a bit more breathing room, I dive into Kali Linux and explore the art of ethical hacking. I also manage The Tech Hub, a programming and technology blog.
