Erik Pillon

Hi, and thanks for passing by! I'm an Actuary with a background in pure Mathematics and Theoretical Physics, currently training for my first 70.3 Ironman in September 2026. From September I'll be also pursuing a MSc in Actuarial Science and Financial Engineering at KU Leuven.

While I'm not a professional software developer anymore, I keep developing webapps and tiny utilities in my free time; feel free to have a look at my Projects page to see what I'm building.

As all curious minds do, I always feel that I never have time to develop as many projects as I want, so my projects naturally revolve around my current interests, like building some sort of financial independence and sharpening my decision-making processes, triathlon, and science communication.

Financial Independence
I'm currently working on a personal finance webapp to track my expenses and investments, and to help me make better financial decisions. Feel free to check it out here and to either register or play around with your imaginary portfolio.

Ideas rarely show up when I'm ready for them, so I'm building a second brain — part analog notebook, part digital tool, still very much a work in progress — to capture and connect them.

Science Communication
Outreach has stayed a constant since my PhD years leading LuxDoc, the University of Luxembourg's PhD Students Association. These days it takes the shape of Scientific Chronicles, a newsletter on the people, dates and discoveries that shaped science, and its companion site, Scientific Chronicles: Anniversaries, a growing archive of scientific anniversaries.

Off the Clock
I'm a competitive triathlete, currently training for my first 70.3 Ironman on 20 September 2026 (half-marathon PB so far is 1:30:37). Race season has quietly retired a few old side projects along the way — a triathlon training dashboard, F1 Analytics and a couple of others — but you can still find them, archived, on my Projects page.

Academic Background
Before all that, I was a physicist. My PhD research focused on efficient numerical methods for non-adiabatic quantum dynamics, specifically the molecular Aharonov-Bohm effect, and you can find an accessible introduction to that work here.


Education

KU Leuven

MSc Actuarial Science and Financial Engineering

September 2026 - ongoing

Starting this MSc to formalize and deepen the actuarial skills I use day to day, with a focus on financial engineering.

University of Luxembourg

PhD in Physics

2018 - 2022

Doctoral research on efficient numerical methods for non-adiabatic quantum dynamics, namely the (molecular) Aharonov-Bohm effect. An accessible introduction to this work is available here.

Alongside my studies, I served on the committee board of LuxDoc, the University’s PhD Students Association, including as President, co-organizing outreach activities such as the Luxembourgish ScienceSlam and the “3 Minutes Thesis” Competition.

Grenoble INP & Institut Neel

Erasmus student

2018

During the period I spent in Grenoble I got the opportunity of exiting from my comfort zone and learn from a completely new environment. I studied 5 months in Grenoble INP focusing on Physics curses and, in the last 6 months, I developed my Master Thesis at Insitut Néel.

Verona University

Master Student in Mathematics

2016-2018

Relevant courses include Advanced Numerical Analysis, Differential Geometry and Stochastic Partial Differential Equations.

I partially paid my studies in this period as teaching assistant of the courses Analysis II and Time Series Analysis (both for Bachelor Students). Alongside my studies I’ve been Representative Student (second time) and I’ve been one of the organizers of the end year event Festascienze(second time).

Utrecht University

Summer School in Theoretical Physics

2018

The Summer School was intended as an advanced undergraduate course in thermal and statistical physics, quantum mechanics and electrodynamics. The final project consisted in an estimate of electric and magnetic fields generated by heavy-ion collisions. In this work we derived analytic formula for electric and magnetic fields produced by a moving charged particle in a conducting medium with the electric conductivity.

Lappeenranta University

ECMI Modelling Week

2018

The final project of the Modelling week required the numerical solution of the 2d Ising Model. Both deterministic and Stochastic methods were implemented.

Verona University

BSc Applied Mathematics

2013 - 2016

Relevant courses include Numerical Analysis, Stochastic Processes, Econometrics and Time Series Analysis.

Alongside my studies I’ve been Representative Student and I’ve been one of the organizers of the end year event Festascienze.
