New academic: Dr. Guillaume Delaittre @ Karlsruhe Institute of Technology
Our first new academic is Dr. Guillaume Delaittre who took up an independent position of Junior Group Leader at the Karlsruhe Institute of Technology (KIT) in Germany by 1st of March 2013. His research will focus on nanostructured polymeric materials for biotechnological and biomedical applications. He has received funding for 5 years from the German Ministry of Education and Research (BMBF) to create his academic position, fund PhD students and postdocs, and run his lab. We invited him to write an essay to describe his pathway and share his experience. His story is summarized below, while the full essay can be found here.
I was born in 1979 and grew up in a small town not far from the Channel Sea in Picardy, France. I enrolled at the University and obtained a 2-year diploma in Sciences of Matter with honors. I then integrated the Institut de Science et Technologie of the University Pierre et Marie Curie. After I completed my degree of Ingénieur there with a six-month traineeship as junior project leader at Cray Valley, my Polymer Chemistry professor, Bernadette Charleux, recruited me for my Master on the topic of controlled emulsion polymerization. Having worked really hard on my exams to obtain a fellowship, I was then able to continue with Bernadette and Maud Save (at IPREM, in Pau, France since 2007) on the same topic for my PhD. As a PhD student I realized the importance of regularly following the literature, especially as a way to gain inspiration. The numerous scientific discussions with Bernadette and Maud also taught me a great deal about how to properly conduct a study, critically evaluate results, and extract the very substance of it.
Towards the end of my PhD it was clear that I wanted to become an academic. I liked the freedom that this field offers, as well as the possibility to create (at least in chemistry) something new, even if I sometimes wonder whether it is still possible! In January 2008 I successfully defended my PhD thesis.
The next month I moved to Radboud University Nijmegen (the Netherlands) in the group of Roeland Nolte, co-advised by Jeroen Cornelissen (now in Twente, the Netherlands) and spent a little less than 2 years there as a post-doc. Afterwards, I have received an Alexander von Humboldt fellowship and started working in Christopher Barner-Kowollik’s research group in June 2010 in Karlsruhe.
How did I finally come to this position? Through a combination of circumstances actually: the right time, the right place, the right boss, the right profile, the right amount of publications… Along almost two years I have applied unsuccessfully for several grant applications. Patience is another required quality in academic research. Towards the end of 2012 I obtained funding from the BMBF for five years in the frame of Biotechnologie 2020+, a national research programme. I will work jointly with Christopher’s team and the Institute of Toxicology and Genetics (ITG) at the KIT. During this long process, my former supervisors helped me with their kind recommendations, young group leaders I did not know provided me with grant proposal examples, and Christopher, Uwe Strähle (head of the ITG), and Jürgen Hubbuch (coordinator of the grant application) continuously showed me great support and reassurance. I also presented my project to several researchers of the KIT who gave me advice and agreed to collaborate with me: this was undoubtedly instrumental to the successful awarding of funds.
Now, when I think about how I personally came to this point, I must say that I became a real fan of the field I chose to work in. Since my PhD, when I am not physically at work, I very often think about the current and possible future projects. I would like to finish with a quote of a professor of Polymer Chemistry who, not so long ago at a conference in Obernai, told me with his Southern French accent: “On est chercheur à l’Université, on est libre: on n’a pas à se plaindre!”. I AGREE.

New academics in polymer science
Dear Polymer Chemistry Blog followers,
We would like to introduce a new category on New Academics in Polymer Science. We will be inviting young academics to share their experiences in becoming an independent academic on our blog. Most of the PhD students and post-doctoral researchers try to answer the same question at some stage of their projects. This question is “How to become an academic?“.
Most of the academics state that they always aimed to become an academic but also a significant number of academics say it just meant to happen. There is one common feeling about becoming an academic, which is competition is getting more and more though everyday. The number of independent fellowships is limited, the candidates have very high number of publications, and permanent academic posts are getting short.
Therefore, we believe it is important to share the experience of new academics to give the next generation an idea about how to become an academic. There is no right or wrong way in this adventure but it is more about the combination or series of actions started during your PhD studies. Every small step in following the literature, creating your own brilliant ideas, presenting, publishing, and networking will make you closer to become an independent academic. Once you think you finally reached your goal, actually it will be just starting!!
Please contact Remzi Becer (r.becer@qmul.ac.uk) if you would like to share your stories on your academic move at any level. We would also like to share the experiences of established academics when they move their groups to another institution. Hopefully, these stories will help the next generation to find their first academic positions!

Paper of the week: Post-polymerization modification of reactive polymers derived from vinylcyclopropane
Monomers based on vinylcyclopropane (VCP) have not attracted a lot of attention in polymer chemistry compared to regular vinyl monomers. This is mainly due to the difficulty in synthesizing them and their polymerisation behaviour. Polymerisation of VCP is known to proceed via a 1,2-type or a 1,5-type, i.e. a radical ring opening polymerization (RROP). RROP of VCP can lead to three different isomeric repeating units: two pent-2-enyl units and one cyclobutyl unit. These different polymerization pathways are the reason why VCP derivatives are not frequently used in polymer chemistry.
Theato et al. have demonstrated the synthesis and polymerization of a new reactive vinylcyclopropane monomer, 1-cyano-1-pentafluorophenoxycarbonyl-2-vinylcyclopropane. The obtained polymer contained exclusively the pent-3-enyl repeating unit in the polymer backbone. Taking advantage of activated ester chemistries, post-polymerization modifications with different aliphatic amines have been conducted. All prepared polymers exhibited an upper critical solution temperature (UCST) in ethanol and ethanol–water. It was found that the UCST was directly related to the amide moiety of the polymer. An increased solubility of the polymer in ethanol with the increase of the volume of the aliphatic amide moiety was observed. The reverse effect was found when adding water to the ethanolic solution of the polymer.
Post-polymerization modification of reactive polymers derived from vinylcyclopropane: 1. synthesis and thermo-responsive behaviour by Denis H. Seuyep N., Gerrit A. Luinstra and Patrick Theato Polym. Chem., 2013, 4, 2724-2730.
