Since September 2018, Mathilde Lepoitevin is an assistant professor in Chemistry at Ecole Normale Superieure, in the Porous Materials Institute of Paris. She was granted a PhD fellowship by Montpellier University (Fr), under the supervision of Dr. Balme and Dr. Bechelany. Her PhD work consisted in developing and designing single solid state nanopores to mimic biological channels and to investigate either bio-macromolecules translocation or to functionalize the nanopore to mimic stimuli-dependent ion channels. During her PhD, she was the recipient of a travel grant from the “Chaire Total” for a short-term stay collaboration work with Dr. Dumee group at Deakin University (Australia). In January 2017, she started working as a postdoctoral research fellow, at Brown University (Providence (RI), USA), under the guidance of Pr. D. Stein. There, she developed and demonstrated a new kind of ion source capable of efficiently transferring single amino acid ions from liquid into a mass spectrometer. Her results indicate a feasible path to single-molecule protein sequencing through a combination of a single-ion source and mass spectrometry. She has co-authored 20 papers in peer-reviewed journals, and her work has been presented in 15 international conferences and 8 invited seminars. She has been the recipient of best PhD award from the “pole chimie Balard” in 2017.
