Geraldine Masson received her PhD (2003) in organic chemistry at the Joseph Fourier University, Grenoble (France), with Dr. Sandrine Py and Prof. Yannick Vallée. In the years 2003-2005 she was a Marie Curie postdoctoral research fellow with Prof. Jan van Maarseveen and Prof. Henk Hiemstra at the University of Amsterdam (Holland). In 2005 she joined the research group of Pr. Jieping Zhu at the Institut de Chimie des Substances Naturelles (ICSN) as a CNRS researcher, before initiating her independent career in 2011. Her research interests include the development of new organocatalytic enantioselective reactions and novel synthetic methodologies, and photoredox catalysis.

Aurélie Claraz received her Ph.D degree in organic chemic chemistry in 2012 at Rouen (INSA) under the guidance of Dr Vincent Levacher. She joined the group of Pr Petri Pihko at the University of Jyväskylä in Finland from 2013 to 2015 as a postdoctoral fellow. She then held a temporary assistant lecturer position in an engineering school in Paris (Chimie ParisTech) working with Dr Sylvain Darses. After a second postdoctoral position in the group of Pr Janine Cossy (ESPCI Paris), she was appointed at the CNRS as research associate in the group of Dr Géraldine Masson (ICSN) in November 2017. Her research interests lie mainly in the field of asymmetric catalysis with a special emphasis on organocatalyst design.

PhD students

Jeremy Merad did his PhD (2012-2015) in organic chemistry at the Institut des Sciences Moléculaires at Marseille (University of Aix-Marseille), under the supervision of Pr. Cyril Bressy and Jean-Marc Pons. During this PhD, he worked in organocalayzed enantioselective synthesis of acyclic diols. From 2016 to 2017, he joined Pr. Nuno Maulide group a Vienna to realized a first postdoctoral fellowship during which he worked on the reativity of sulfonium ylides. In March 2017, he joined Dr. Masson’s group for a second postdoctoral position to work on organocatalysis and photoredox catalysis.


Lucie Jarrige obtained her Bachelor degree in chemistry from the Université de Bordeaux I and her M.Sc. from the Université Paris Sud XI (2014). During her Bachelor degree, she made two internships for one month at IECB and one of two months at ENSCBP (Bordeaux). During her M. Sc, she madetwo internship for six months at he went for 6 months at Institut de Recherche Servier (Suresnes) and at Institut de Chimie des Substances Naturelles under the supervision of Dr Philippe Dauban. Since October 2014, she works in Dr. Géraldine Masson’s group on the total synthesis of Padanamides A and B. Outside the laboratory, Lucie likes climbing and singing.

Coralie Gelis obtained her Bachelor degree in chemistry from the Université de Bordeaux I and 1st year of M.Sc. from the Université Paris Sud XI. Before, she made different internships in team «SMART» at IBMM (Montpellier) under the supervision of Frédéric Coutrot, and «Synthesis and bioactive molecules» at ISM (Bordeaux) under the supervision of Magali Slozeck then in the team «E2C» at Sanofi company. Since 2015, she has joined the team of Dr. Géraldine Masson for an internship of six months and then her PhD. She is currently working on hypervalent iodine catalysis. Outside the laboratory, Coralie likes playing viola, listenning music and doing sports, except with a ball.

Guillaume Levitre obtained a Technology University Degree in Chemistry from the Université Paris-Est Créteil (UPEC). During which he completed an internship at the UFPE in Recife (Brazil) in Prof. Marcelo Navarro’s team. Subsequently, he obtained a Bachelor’s degree in Chemistry-Biology and then a Master’s degree in Organic Chemistry from the Université Paris-Sud XI. During his master, he carried out two internships. A first one of 5 months in Prof. Thierry Ollevier’s group at the Université Laval (Quebec) and then joined the team of Dr. Géraldine Masson at the Institut de Chimie des Substances Naturelles (ICSN) for a six-month internship where he pursues in PhD since October 2016. Outside the laboratory, Guillaume loves sports, especially martial arts, as well as theater.

Tuan Le is a pharmacist in Viet Nam. He obtained the IDEX Paris Saclay Excellence Scholarship to come to France to pursue two years of a Master’s degree in Pharmaceutical Chemistry at the UFR Pharmacy of the University of Paris Sud XI. During the first year of the Master’s program, he completed a two-month internship in the BIOCIS laboratory, UFR Pharmacie, University Paris Sud XI, under the supervision of Pr. Delphine Joseph. Tuan joined the Géraldine Masson team at the Institut de Chimie des Substances Naturelles in January 2017 for a six-month internship - a collaborative project with Prof. Pierre Auderbert and Dr. Clémence Allain of the PPSM laboratory, ENS Paris Saclay. He pursues his Ph.D studies in the group since October 2017. His project aims to use tetrazines as a photoredox organocatalyst. Outside the laboratory, Tuan loves cinema, photography and travel.

Potter joined our team a long time ago… He loves listen to us talk about chemistry during our breakfasts every morning and we cheer up if necessary. In his spare time, he enjoyed eating, sleeping, and swimming.
