Jasmin Christian Blanchette
ジャスミン・クリスチャン・ブランチェット 亚斯麦·克里斯蒂安·布兰切特


I am an assistant professor in the Theoretical Computer Science section of
the Vrije Universiteit Amsterdam, Netherlands.
I am also a guest researcher in the VeriDis group at Loria in Nancy, France, and in the Automation
of Logic group at the MaxPlanckInstitut für
Informatik in Saarbrücken, Germany.
I was a postdoc at the Chair for
Logic and Verification at the
Technische Universität München, Germany, which I joined in
2008 as a Ph.D. student.
From 2000 to 2008, I worked as software engineer and documentation manager for
Trolltech (now The Qt Company) in Oslo, Norway.
My research focuses on the use of firstorder automatic
theorem provers and model finders to find proofs and counterexamples in
higherorder logic (Sledgehammer, Nitpick,
Nunchaku,
and Matryoshka).
Another aspect of my work is the development of foundational definitional mechanisms for
(co)datatypes and (co)recursive functions.
I am also interested in formalizing classic results and modern research in
automated reasoning (IsaFoL).
News
 I will be giving a joint invited talk at
FroCoS,
ITP,
and TABLEAUX
2017 in Brasília about (co)datatypes and (co)recursion in
Isabelle/HOL.
 Pascal Fontaine and I are looking for outstanding candidates
for Ph.D. positions and internships to start in 2017 and 2018,
located in Nancy or Amsterdam.
See the Matryoshka project page
for details.

Teaching
I will be teaching Logical Verification
during period 5 of 2016–2017.
During the 2015 summer term, I taught
Concrete
Semantics with Isabelle/HOL at the Universität des Saarlandes with
Mathias Fleury and Daniel Wand.
During the 2012–13, 2013–14, and 2014–15 winter terms, I was the proud
Master of Competition
for the course
Einführung in die Informatik 2
at the Technische Universität München.
Supervision
Note to students: Please send me an email if you are interested in working under my supervision.

What kind of a proof?
It's a proof.
A proof is a proof,
and when you have a good proof,
it's because it's proven.”
