Prof. Clara Viñas graduated in Chemistry at the Universitat Autònoma de Barcelona in 1975 and in Pharmacy at the Universitat de Barcelona in 1980. She worked as a pre-doctoral student at the Prof. Rudolph’s laboratory at The University of Michigan for a year. Back to Barcelona, she worked for industry and later moved to Laboratori Municipal de Sabadell where she became the director to work on food and environmental control. She got her PhD in Pharmacy under the supervision of Prof. F. Teixidor at the Universitat de Barcelona in 1990. She joined the staff of the C.S.I.C. as tenured scientist in 1991. She promoted to research scientist in 2002 and to research professor in 2006.
