My ENSTA Years : "Many opportunities and a high level of research."

After a Ph.D. in organic and materials chemistry, Universities of Angers (France) and Zaragoza (Spain) in 2001 : project of 4 years in Angers, funded by CNRS (National Centre of Scientific Research) and including 1 year’ studies and formation (HPLC, MS, RPE) in Zaragoza and Barcelona (Spain), a Post-graduate diploma before the Ph.D., specialization in materials chemistry (DEA Chimie Fine) at the Science Faculty, University of Angers, an Engineer's diploma at Ecole Nationale Supérieure de Chimie de Montpellier (ENSCM), a leading National College of chemical engineering, a Postgraduate engineering degree, equivalent to M. Sc. plus one year specialisation in organic and materials chemistry, biochemistry and environment and aMaster of Science specializing in physical chemistry, University of Grenoble, including 9 months’ studies in Montreal and Ottawa (CANADA) through an exchange between France and Quebec, David Kreher became a part of the ENSTA ParisTech by integrating the department of chemical engineering.

What are your activities at ENSTA ParisTech ?

I was approached with the idea of first, preparing novel teaching modules for ENSTA students, and second developing novel research topics. More precisely, I was assistant Professor in Pierre and Marie Curie University (UPMC) for 8 years, and currently I am doing in ENSTA the same professional activities, except it is more challenging as here the ultimate aim is to create a novel long term activity related to my competences.

What is your field of studies ?

My background deals with organic chemistry and physical chemistry of molecular and/or polymer materials. Consequently, I have essentially competences in multi-step synthesis, polymer synthesis, as well as all the chemical structure characterizations dedicated to such materials. I take advantage of these tools to target novel organic 2D and 3D auto-assemblies (liquid crystals, controlled architectures…).

What are the possible applications of these researches ?

All the materials I am working with are designed such a way that we could expect applications either in optics (organic lasers, frequency doubling), in photonics (two-photon absorption, surface nanostructuration), or in the innovating field of organic electronics and corresponding devices (LEDs, photovoltaic cells, Transistors).

What courses are you in charge of ?

I am in charge of different optional teaching modules during the second year, I mean the one related to “materials and energy” (where we present essentially the issues in the area of photovoltaics) and the one dedicated to “innovating materials and polymers for new applications”, where we initiate the students to the materials of the future or the materials being already everywhere to improve our life.

What do you think are the benefits of the ENSTA ParisTech courses ?

ENSTA formations are various and of high quality, being during the first years quite general and allowing the students to chose specializations later on. Moreover, there are lots of opportunities to spend one year of the cursus abroad, to perform another language and simultaneously open his eyes on the world. Everything is then positive to permit our students to be very successful in their future professional activity.

What are the benefits of our laboratories ?

The different laboratories of ENSTA are well evaluated, well-known internationally also, included as well very often shared research units or important research topic interactions with CNRS, with Ecole des Mines, with Ecole Polytechnique,  …) : this guaranties a high level of research, professors being then able to transmit their knowledge to the students at a high level as well.
