Maria Helena de Sá is a chemist. She graduated in 1993 from Faculty of Sciences of the University of Porto (FCUP), where she also completed a Master degree (Computer simulation of biomolecules) in 1996 and the PhD (Electroanalysis) in 2002.

Since then she has worked as science teacher and as a researcher in the field of Materials Science and Nanotechnology, for several national and international projects, with different applications. Recently, she joined the Transport Phenomena Research Center (CEFT) at the Faculty of Engineering of the University of Porto (FEUP), as postdoctoral researcher hired to support the NewPortCell project.

She has authored several papers in reputed international journals, one book chapter and has been invited to review manuscripts in international peer-review journals in her area of expertise. She has also been involved in different project out-reach activities, including acceleration programs like 2017 COHiTEC and Resolve.
