Motivation: why a PhD ?
• To achieve a complete academic career and get an international diploma with a 3 year financed contract
• To learn and master the research methodology: become an expert ! Develop my skills, improve my knowledge and be critic.
• To solve a tricky problem I have interest for • To start a career at the university (professional plan)
A PhD diploma is needed to apply for the position of assistant professor
PhD started the 1 October 2012

My work as a PhD
October 30, 2007 © SKF Group Slide 3
• Modeling of contact problems: thermal and solid mechanic aspects
contact surface roughness
subsurface inhomogeneities
material microstructure
• Develop a numerical tool based on advanced techniques to solve these problems
What did I learn during my PhD ? Scientific aspect
• Learn how to search in the bibliography and extract the information
First phase of a research project Papers, reports, books… • Improve my scientific knowledge, be creative
and develop my own tool
Learn from the bibliography and the people we work with Define innovative and valuable projects Create or improve tools
• Ask the good questions and answer it
How to perform validations ? Are the results physically acceptable ? Is it necessary to always go deep in the analysis ?

What did I learn during my PhD ? Administrative aspect
• Project management - Define objectives and strategies - Schedule - Respect the deadlines
• Write reports
- Master text editor (word, latex) - Organize theory and results - Write a bibliography
• Organize and lead meetings
- How to efficiently present work - Present both difficulties and success - redefine things if necessary - be responsible

What did I learn during my PhD ? Become visible worldwide !
• Write publications
- learn to write scientific paper - emphasize results - receive critics from specialists
• Participate to international conferences
- get the opportunity of present and defend my work - improve communication skills - share and exchange with experts • Develop a network - visit colleagues from other universities and create collaborations e.g.: Christian Gauthier, Institut Charles Sadron - exchange with company representatives

What did I learn during my PhD ? Prepare the future
• Instructorship 192 teaching hours Solid mechanic team: Michel Coret. Seminars: traction, torsion… Prepare the lectures Supervise students Evaluate the students Discussions with the team to solve problems and improve the quality of the seminars • Training (CIES) Methods for teaching Career plan Be prepared for the assistant professor activities • Some tools to start a network

A Post-Doc experience
• 2012-2014: University of Twente The Netherlands
• Supervisor: Pr. Kees Venner head of the fluid dynamic department
• Funding: FOM (Dutch foundation) and SKF-ERC
• Objectives: improvement of the model develop during my PhD solve the full contact problem (surface and subsurface) take into account large property variations in the material develop a model to deal with near-incompressible material 2 articles have been published
• Benefits:
- Discover new methods - Work with an international team - Collaborate with a company - Improve my language skills
