Clément Legrand Duchesne

École Normale Supérieure de Rennes

I am curently studying computer science at ENS-Rennes.

I'm mainly interested in algorithmic, graph theory and math (especially algebra and discrete mathematics).

Academic Background

Bachelor of computer science

Mathematic courses (Lebesgue integration, convex optimisation, algebra).
Computer science courses (system, security, algorithmic, computer programming, formal langage and computability).
September 2017 - Present


Two years of hard work in mathematic, physics and computer science in order to join the ENS.
September 2015 - June 2017

Scientific High School

In tenth grade: ISN option (very basic computer skills, programming in Python).
In senior year: mathematic option.

Baccalauréat GPA: 18.02/20

September 2012 - June 2015

Projects and personal experience

TIPE: Randomized and Approximation Algorithms for the Max Cut Problem

My interest in algorithms and graph theory led me to implement approximation algorithms for the Max-Cut Problem, and evaluate their theorical and empirical efficiency. Here is the TIPE report for the ENS competitiv exam.
January 2016 - May 2017

TPE: Mechanics of skateboard tricks

I was only in eleventh grade, but here is the TPE report for the Baccalauréat anyway. I was then a longboard enthusiast so I had a great time working on this topic.
September 2013 - May 2014

Three months in Forchheim, Bavaria (Germany)

I spent the beginning of ninth grade in Germany, doing a language exchange.
September 2011 - December 2011

A year in San Diego, California (USA)

I spent my second grade in an american elementary school.
September 2004 - July 2005


Programming Languages
  • OCaml
  • Python
  • C/C++
  • Lisp
  • R
  • Java (still working on it!)
Human Languages

I speak English, French (and German but not fluently).

Social interactions

I am a trained cup and ball gamer.


When I'm not working, I enjoy doing sports. I practise block climbing and cross-country unicycle several times a week. I am also a rugbyman and a gymnast.

I am also a big ski and snowboard enthusiast, and love surfing or going for a ride on my longboard in summer.

When the weather isn't good enough for those activities, I like to read (mainly Sci-fi and Heroic Fantasy), to listen to music or to play classic guitar. I am also a big fan of cooking.
