Research
Microarchitectural Security Research
I build efficient and systematic tools for analyzing and improving microarchitectural security in black-box CPUs. Working with Professor Gururaj Saileshwar, my current work focuses on microarchitectural side channels that leak data across security boundaries.
- Supervisor: Professor Gururaj Saileshwar
- Award: Department of Computer Science Summer Research Award (NSERC USRA equivalent)
- Status: New findings in progress — stay tuned
Skills
Softskills
I have developed many softskills through years of volunteering & work experience, such as critical skills in leadership, collaboration, commmunication, organisation, and initiative. I have worked with many different communities to solve their unique challenges. I am also multilingual, fluent in English, French (DELF B2), and mandarin - a critical asset in our multicultural country.
Languages
Fluent in English, French (DELF B2 certified), and Chinese (Mandarin). Always happy to chat in any of those languages!
Object Orientated Programming
Understanding in the topics of, but not limited to: design principles, encapsulation, composition and inheritance, data representations (Abstraction and ADTs), program control flow, software engineering principles (formal specification and design, testing and verification).
Number Theory and Cryptography
Understanding in the topics of, but not limited to: Theorems, Proofs, and Algorithms (such as Fermats Little Thoerom, modular arithmetic, Euler's Theorem); cryptography (Diffie-Hellman key exchange, RSA, One-Time Pad), computational complexity
Data Structures and Algorithms
Understanding in the topics of, but not limited to: abstract data types and data structures (stacks, queues, linked lists, trees, graphs), sorting algorithms (Selection Sort, Insertion Sort, Mergesort, Quicksort, Timsort); recursion and mathematical induction, well-ordering-principle, binary representation of numbers, algorithms and running time analysis, deterministic and non-deterministic finite-state automatas. Proving algorithm correctness.
