From experience to education

Experience

University College London (2016-2021)

Teaching Assistant in the Statistical Science and Computer Science departments, instructing courses in Probability, Statistics, and Programming Methods.
I received recognition as the Best Tutor within the Computer Science Department (2019) and was awarded the UCL Faculty Education Award. I was also shortlisted for the prestigious UCL Provost's Education Award, competing against more experienced faculty members.

Student Supervision


I supervise/ed graduate and doctoral students across multiple institutions:


PhD students at University of California Santa Barbara and University of Technology Sydney focusing on cross-curve interest rate stress testing and green bond yield analysis.


Master's students at the Hearing Institute from various French Schools such as Sorbonne University (Machine Learning), ECE Paris (Acoustics), and AIX-Marseille Université in different audiological applications.


Philosophy


My approach to teaching is grounded in the belief that theoretical concepts must be connected to real-world applications. I emphasize the development of both technical proficiency and critical thinking skills, encouraging students to move beyond formula memorization to deeper understanding of statistical principles.


I value creating an inclusive learning environment where students from diverse backgrounds can thrive. Drawing from my experience as a professional athlete, I incorporate collaborative problem-solving and team-based learning that prepares students for careers in both academic and industry settings.


I believe in adaptive teaching methods that respond to individual learning styles, using a combination of traditional instruction, interactive demonstrations, and hands-on project work to engage students with different strengths and interests.
