Not pretty enough
13
• “The cat that walked by himself” – passion for travelling
Eureka !
Science is not like that
14
Me, Myself and I
Old-fashioned style
But more like that
15
Collaborative research
Jigsaw puzzle

But also…
32
Cover !
A bit more
relaxed !
In spite of appearances
33
Sciences Arts
Humanities
“European academy of arts, sciences and humanities”…
No distinction
34
Sciences Arts
Humanities
To do the
job !
To draw lovely
figures
To write deeply
moving texts
Two examples (1)
35
“Total synthesis”
(the art and science of
replicating the molecules of
living nature and creating
others like them in the
laboratory)
K. C. Nicolaou, Proc. R. Soc. A 470: 20130690
Two examples (2)
36
Collaboration with an Art Restorer
(understand the origin of glueing failure)
Results currently used by:
Getty Museum, Los Angeles (US)
Grabart Art Conservation Centre (Russia)
37
2. How ?
You
Me
My boss
French System
38
Elementary School
Junior High School
High School 16-20 years old (~18)
An unexpected journey
• After high school
39
“Classe préparatoire aux grandes écoles”
Higher School Preparatory Classes two (very) intensive years preparatory course for
enrollment in one of the grandes écoles (Engineering schools)
The workload is one of the highest in the world
Step 1
• Engineering School
– Three years to refine your choice
(chemistry, physics, economics, mathematics, …)
– Major: Chemistry with a strong emphasis on mathematics
40
What I was
supposed to
become
What I chose
Step 1.5
• Engineering School
– Three years to refine your choice
(chemistry, physics, economics, mathematics, …)
– Major: Chemistry with a strong emphasis on mathematics
– Last year: MSc in Analytical Chemistry (double degrees)
41
Step 2
• PhD
42
First blood...
Key point: Finding money First PhD position (in France)
Cancelled one month before starting
What’s to be done ???
Step 2
43
• PhD What’s to be done ?
Second offer:
Terrific topic (restoration of statues) but not enough money to survive
Step 2
44
• PhD What’s to be done ?
Third offer:
It’s the right one ! (Luxembourg)
Step 2.5
45
• PhD
2 years and a half
(up to 5 years…)
15 publications
14 conferences
One dissertation (300 pages) + oral defense
Step 3
46
The day of my
defense
Step 3
47
The day of (my)
defense
1 h lecture
+ 1-3 h of questions from the board (about the 300 page dissertation)
Step 3
48
Step 4…
• And to follow ?
• First position: R&D Engineer
(and post-doc 1)
49 MS in polymer chemistry – T. Fouquet, Jan 6th, Nagoya Institute of Technology
(Grand Duchy of) Luxembourg
Pop. 550,000 hab (2014)
2 years and a half, two contracts
Fixed term position(s)
which should have been turned into permanent contract…
• First position: R&D Engineer
(and post-doc 1)
…and 5
50
+ =
…But nope 
+
Merger = please take a hike !
Step 5.5
51
What’s to be done ?
Use personal connections (=network) to find a new position
(+ job alerts, naturally)
Step 5.5
52
What’s to be done ?
Onto new adventures
53
JSPS post doctoral program for
overseas researchers
Two-year position at AIST
(National institute for Advanced Industrial Science and
Technology)

Mass Spectrometry
59
Mass Spec (MS)
The key point
Neutrals ~ inerts
Ions: sensitive to
electric/magnetic fields,
easily manipulable
Soooo versatile !
60
Soooo versatile !
61
Tandem mass
spectrometry
→ to decipher the ions
architectures
Soooo versatile !
62
Gas phase ion chemistry
→ to check at the reactivity
(thermodynamics and kinetics  )
Soooo versatile !
63
Ion mobility – mass spec
→ to get insights into the
shape of ions
Isotope ratio – mass spec
→ relative abundance of
isotopes
Radiocarbon dating technique
12C vs. 14C
An infinite number of applications
64
Proteomics
Determine protein structure, function, folding and interactions
Drug Discovery
Clinical Testing
Forensic Analyses
Environment
Test water quality or food contamination
Geology
Measure petroleum composition
Space exploration (comet, Mars, …)
Chemistry
Composition and structures of new compounds
Reaction kinetics
Two sexy apps
65
Imaging
“I-knife”
A word about my business
66

71
Synthesis
(create monomers/polymers)
Elaboration
(shaping, composites)

4. And to follow ?
Any big plans ?
74
Depending on how life’s going here in Japan (+ language)
- Stay in Japan for a couple of years more
- Or settle the US for a while
Any big plans ?
75
Depending on how life’s going here in Japan (+ language)
- Stay in Japan for a couple of years more
- Or settle the US for a while
- Research center or company
Much more money
(on average)
Little freedom

5. The last hurrah
Handy hints
• “Network” + supervisors (keep in touch)
• Do not neglect the other domains
• Keep learning English
