My Journey

An overview of my academic and continuous learning journey, which has forged my ability to approach various problems with a rigorous methodology.

From Fundamental Research to Data Science

Period: 2016 - Present (Continuous Learning)

After my PhD, my curiosity led me to data science, a field that was already popular in the United States but still relatively emerging in France. I quickly grew fond of this field, a gateway to many others (medical, financial, socioeconomic...). Today, I explore both the theoretical foundations of algorithms and their concrete applications with the same curiosity, while also having the pleasure of transmitting this passion as a trainer in higher education.

Details of my main training and certifications

Continuous Learning Platforms

  • Datacamp (since 2018): Constant learning and practice on the entire data ecosystem (Python, SQL, Machine Learning, Data Engineering...).
  • Coursera: Beyond Andrew Ng's foundational certifications ("Machine Learning Specialization" & "Deep Learning Specialization"), I use the platform for active monitoring and continuous learning across a broad spectrum of IT topics.
  • Google Cloud Platform (GCP): Deepening my expertise in the GCP ecosystem to take data projects from experimentation to production. This includes data architecture (BigQuery), model deployment (Vertex AI), and business intelligence (Looker Studio).

Advanced & Research-Level Training (AI)

  • Stanford University (online): Followed the course CS236 - Deep Generative Models. Achieved very good results on exams and practical workshops, and while I couldn't submit the final project due to lack of time, I independently advanced my VAE model project on brain MRIs with TensorFlow to an advanced stage.
  • Sorbonne University (from Sep. 2025): As part of my continuing education, taking Master's level Teaching Units specializing in Computer Vision, with a focus on the opportunity to collaborate with brilliant students.
  • Active Watch: Regularly following courses and seminars from Stanford and other leading institutions through their publications and YouTube channels.

IT Journey Anecdotes

“My first encounter with a computer, in the mid-80s, was a Commodore PET inherited from my uncle. A machine with a cassette tape drive for storage and a screen that only displayed characters, but it had immense sentimental value. A few years later, when I was 9 or 10, I learned to program in Omikron Basic on an Atari 520 STE whose memory had been expanded to... a whole megabyte!”

“The first program I was proud of on the Atari was a small game: a yellow circle, moved with a joystick, that would leave a trail if you held down the button... but for no more than 20 seconds, or it would turn red and the game was over! That was the era of BASIC, with its numbered lines and GOTO statements. Since then, I know I must make great efforts for the readability of my programs!”

PhD in Physics and Chemistry of Materials

Topic: Electronic correlations of acenes towards the large size limit: a Quantum Monte Carlo study
Laboratory: Institute of Mineralogy, Materials Physics and Cosmochemistry (IMPMC), Paris | 2012 - 2016

Under the supervision of Prof. Michele Casula and Prof. Francesco Mauri, my PhD research focused on predicting the electronic properties of molecules—acenes—which are precursors to graphene nanoribbons.

The objective was to better understand, through numerical simulations, the quantum behaviors that could lead to future applications in spintronics or energy storage.

This research work and the high standards of my mentors allowed me to develop a set of fundamental skills:

Anecdotes

“I am proud to be the first in my family to obtain a doctorate, but I cherish even more the qualities passed down by my family, including the humor of my late grandfather, who loved to remind me: 'I have diplomas too! I got my primary school certificate at 14!'”

“I obtained my PhD at 36. For a long time, I saw private tutoring as my lifelong profession, but the flexibility of this activity allowed me to explore many fields as an auditing student and to stay connected to the academic world.”

Mathematics Curriculum (Bachelor's & Master's)

Period: 2002 - 2005 (and subsequent isolated courses)

I studied fundamental mathematics, obtaining a Bachelor's degree with honors ("Mention Bien", 0.25 points shy of highest honors) and a Master's degree ("Mention Assez Bien"), as well as credits from the second year of the Master's program. This path forged my reasoning and abstraction abilities, and the art of the proof.

Details on courses and journey anecdotes

Main Subjects Studied by Level

Bachelor's Degree: Topology, algebra and geometry (group theory, linear algebra, projective geometry), differential calculus, differential equations, measure theory and integration.

Master's Degree (Year 1): Functional analysis and spectral theory, algebra and Galois theory, probability, differential geometry.

Master's Degree (Year 2, partially completed): Dynamical systems, Algebra and Lie groups.

Journey Stories

“At 18, I was convinced I was bad at mathematics. No one, not even me, would have bet that I would come this far, and I have no intention of stopping, no matter how long it takes!”

“My passion for mathematics was born in books. I started with a high-school level textbook to catch up, and in it, I discovered the beauty of rigorous proofs. Over the years, this curiosity has grown into an ever-expanding collection of scientific works, much like others collect vinyl records. I immerse myself daily in re-reading a few pages.”

“At 20, I had an ambitious dream: to get into the École Normale Supérieure by competing against the best students from the 'classes préparatoires'. For two years, I trained as one trains for a marathon. While I did not reach the final goal, I faced 6-hour exams with a difficulty comparable to the International Mathematical Olympiad. I still like to practice as if I were going to take the exam again tomorrow.”

Opening up to the World: Languages and Cultures

Skills: Continuous and passionate learning of several languages

My passion for languages goes beyond technical skill. It is the path to new cultures and new encounters. Each language opens up the hope for new connections.

Details of my linguistic journey

Levels and Stories

  • French: Native speaker.
  • English (Level B2-C1): Fluent in reading scientific literature, practiced regularly.
  • Russian (Level B1-B2): Two years of intensive study at INALCO alongside my Master's in Mathematics. I continue to study it, notably through poetry.
  • German (Level B1-B2): Learned in high school, I periodically revive it out of love for the language, even if speaking remains arduous.
  • Estonian (Level A2-B1): My current great love! I stay in Tallinn every summer and improve by meeting up with my friends. I've been reading the children's book "Sipsik" for 4 years and I'm in no hurry to finish it! I love the poetry of Jaan Kaplinski.
  • Czech & Hungarian (Level A2): Taught myself intensively for regular trips a few years ago. I loved the intellectual challenge of learning these two rich and different languages in parallel.
  • Swedish (Beginner): A passion for the language, fueled by excellent Scandinavian thrillers like "Brön/Broen" (in which Sofia Helin was formidable).
  • Italian (Level A2): How can one not love this language! Especially with a PhD team that was predominantly Italian.
  • Chinese (Beginner): A slow start over several years. I finally found immense pleasure in learning the characters thanks to an online pen pal and friend, who in turn was learning French.

Learning Anecdotes

“I started Russian at 25, initially to 'get my mind off' mathematics. In it, I discovered the pleasure of meeting new people and understanding another culture. Much more than seeking a skill for a resume, learning languages allows me to be there for others.”

“As a neuro-atypical person, I suppressed my desire to speak for a long time, for fear of being judged. Learning a foreign language was liberating. Far from home, efforts are often met with kindness by others. It gave me the courage to express myself again, even if being judged for my sometimes 'weird' intonations remains a challenge for me in French or English.”

Commitments and Hobbies

Philosophy: A balance between discipline, pleasure, and mutual support.

Beyond my professional and academic life, my passions bring me balance. I have always enjoyed committing to what motivates me, not for the sake of performance, but for the pleasure, for sharing and contributing.

Details of my commitments

Martial Arts

18 years of Vovinam Viet Vo Dao practice, including 6 years as club President. I had the pleasure of getting involved to help my fellow members, share my passion, and manage our association's life.

Other Sports

Sports remain essential to me. I am an eternal beginner in artistic gymnastics, and I occasionally enjoy swimming or rock climbing. My sole motivation is the pleasure and well-being, with no search for performance.

Volunteering

I am committed to regularly donating blood and, more frequently, platelets. I have surpassed fifty platelet donations since I started in university, and I am happy to help medical teams with the little I can do.
