Four days at SOLEIL Synchrotron on DISCO beamline for photoswitchable peptide studies

The DISCO beamline at SOLEIL welcomes us for four days at Synchrotron SOLEIL from 6th to 9th July. This is a collaboration with Dr. Frank Wien (beamline team) and Dr. Séverine Zirah (Muséum National d’Histoire Naturelle), to study the structure of photoswitchable peptides. This is supported by SOLEIL.    

We are at #SFST7: 7ème Symposium Francophone de Synthèse Totale, 1-2 June

We will be at SFST7 at Orsay, 1-2 June 2017. Wei and Bastien attend. Wei will present her poster on her synthetic work: Biomimetic oxidative strategies and alternative route for the synthesis  natural products in the diketopiperazine series. Bastien co-organizes the symposium.

Ombeline hunting toxic mimetic butterflies in Peru

Ombeline Sculfort is currently hunting toxic butterflies in Peru near Tarapoto. She will spend four months there. The aim is to study and understand the evolution of toxicity in mimetic butterflies. This is a collaborative project with the French National Museum of Natural History.

Congrats to Dr Benjamin Laroche who got the YNSECT PhD Award of the SCF Ile-de-France Section.

Benjamin got the YNSECT PhD Award of the SCF Ile-de-France Section in recognition of his PhD work on natural product total synthesis. He will present his work on the occasion of the Journée des Jeunes Talents de la Chimie en Ile-de-France 2017 on 19th June 2017. Benjamin currently performs a postdoc in Shu Kobayashi’s group […]

Last day at Museum on 30th December 2016

… and a quizz: when did it happen?
