Margarida Cunha is a Principal Researcher at IA. She was awarded a first degree in Physics/Applied Mathematics by the University of Porto in 1994, the Advanced Certificate in Mathematics (Part III) by the University of Cambridge, UK, in 1995 and a PhD by the University of Cambridge, UK, in 1999. She is a member of IA since its creation.
Current research interests focus on asteroseismology and helioseismology. In particular, she is interested in the development of seismic diagnostic tools aimed at exploring space-based data to infer particular aspects of the stellar physics and understand stellar evolution, as well as on the understanding of the coupling between the magnetic fields and solar/stellar oscillations.
Margarida Cunha is currently chair of the Working Group #4 (AF Classical pulsators) for the TESS Asteroseismic Science Consortium (TASC), in association to the NASA mission TESS, and Chair of the Work Package #124000 (seismic diagnostics), for the PLATO Science Preparation Management (PSM), in association to the ESA PLATO mission.
In addition, she is a member of the WP120 Board for the Stellar Science part of the PLATO PSM and former leader (2015-2018) of the IA group “Origin and Evolution of Stars and Planets”.
