Louwanda LAKISS

CNRS Research Engineer, LCS

Louwanda is a research engineer at CNRS, France. She received her PhD in physical chemistry at the University of Haute Alsace (France) under the supervision of Dr. Joël Patarin. The focus of her research is in the fields of synthesis and shaping of microporous materials, advanced characterizations by spectroscopy and catalysis. Her main research interests focus on advanced characterization of zeolites by infrared and NMR spectroscopies, using appropriate probe molecules.
