Maria Jesus Villasenor completed her PhD in Analytical Chemistry at 28 years old, at Castilla- La Mancha University in spectrophotometry and electrochemistry fields. Later, she carried out two postdoctoral collaborations with the Institute of Organic Chemistry (CSIC) and the University of Amsterdam (Analytical Chemistry and Polymers Area) being specialized in gas chromatography-mass spectrometry and different modes of capillary electrophoresis, respectively. Nowadays her research interests are focused on new optical and electrochemical sensing nanomaterials-based strategies and on the design and analytical control of NOMs obtained by means of nanoencapsulation methodologies, within the research group SAMAN (Simplification Analytical MinituArization and Nanotechnologies).
