What is your academic background and professional experience before coming to CEA?
I started in 2009 as a PhD student at the Laboratory for Crystallographic Studies of Granada, Spain. My research topic was the study of nucleation in small volumes and confinement, covering a wide range of different backgrounds, from nanoparticle synthesis for biomedical applications to biomineralization and small molecule crystallization. From this period, I started developing my own microfluidic tools to handle the small volumes required for my studies. For that purpose, during my PhD, I performed several internships in well-recognized international research institutions, such as the “Centre Interdisciplinaire de Nanoscience de Marseille”, the “Dipartamento Chimica C. Ciamician, Alma Mater Studiorium” from Università di Bologna, Italy, and the “Institut de Microelectrònica de Barcelona”, Spain. From this last internship, I started collaborating with the “Chemical Transducers Group” of the IMB-CNM in the development of lab on chip systems with integrated photonic detection and its application in crystallization studies. This collaboration continued with a two-year postdoctoral researcher position in which I acquired expertise in microfabrication techniques and clean room processes to be applied in the development of photonic lab-on-a-chip platforms (implementation of micro optical elements and photonic detection systems in microfluidic structures) using silicon and polymer technologies. During my last year in this position, I was contacted by Dr. Sébastien Teychené, from the Laboratoire de Génie Chimique de Toulouse (Toulouse Chemical Engineering Laboratory) and Dr. Sophie Charton from CEA Marcoule (www-marcoule.cea.fr), and they offered me to build up a project together that finally ended up in this Incoming CEA fellowship.
Could you tell us about your research project? (Topic, team, equipment, progress…)
I work for the Laboratoire de Génie Chimique et Instrumentation (LGCI – Laboratory for Chemical Engineering and Instrumentation) belonging to the Departement de Technologie du Cycle du Combustible (DTEC – Fuel Cycle Technology Department), at CEA-Marcoule, in a cooperative project (together with Dr. Teychené and Dr. Charton) with the Laboratoire de Génie Chimique de Toulouse (LGC-CNRS). The project aims at developing novel photonic lab-on-a-chip platforms and methodologies for the study of precipitation and growth kinetics of rare earth salts, involved in hydrometallurgical processes and nuclear waste treatment. The miniaturization of the current methodologies presents a series of important advantages, from the reduction of sample consumption (interesting from both economical and safety points of view when working with high-value reagents and radioactive materials) to the possible increase of analytical performance in terms of precision, sensitivity and limit of detection. Although the main team is made up of 3 people, we all collaborate with other members at CEA and other international academic institutes.
