She is a professor of mathematics at EPFL (École Polytechnique Fédérale de Lausanne) and holds the Chair of Numerical Modeling and Simulation.{{Cite web |title=23 professors appointed at ETH Zurich and EPFL {{!}} ETH-Board |url=https://www.ethrat.ch/en/medien-medienmitteilungen-news/23-professors-appointed-eth-zurich-and-epfl |archive-url=https://web.archive.org/web/20210115045039/https://www.ethrat.ch/en/medien-medienmitteilungen-news/23-professors-appointed-eth-zurich-and-epfl |archive-date=15 January 2021 |access-date=29 January 2021 |website=www.ethrat.ch}}{{Cite web|title=MNS|url=https://www.epfl.ch/labs/mns/|access-date=29 January 2021|website=www.epfl.ch|language=en-GB}}

Education and career

Buffa received her master's degree in computer engineering in 1996 and received her PhD in 2000, with supervisor Franco Brezzi, from the University of Milan with thesis Some numerical and theoretical problems in computational electromagnetism.{{MathGenealogy|id=177600}} From 2001 to 2004 she was a Researcher, from 2004 to 2013 a Research Director (rank equivalent to Professor), and from 2013 to 2016 she was the Director at the Istituto di matematica applicata e tecnologie informatiche "E. Magenes" (IMATI) of the CNR in Pavia.{{Cite web |date=19 April 2016 |title=Cnr, 2,5 milioni di fondi europei per le ricerche della matematica Annalisa Buffa |url=https://www.repubblica.it/scienze/2016/04/19/news/cnr_2_5_milioni_di_fondi_europei_per_le_ricerche_della_matematica_annalisa_buffa-137949632/ |access-date=12 February 2023 |website=la Repubblica |language=it}}

In 2016 she was promoted to Full Professor of Mathematics. She holds the Chair of Numerical Modeling and Simulation at EPFL.

She has been a visiting scholar at many institutions, including the {{lang|fr|Laboratoire Jacques-Louis Lions}} at the University of Paris VI, the École Polytechnique, the ETH Zürich, and the University of Texas at Austin (Institute for Computational Engineering and Sciences, ICES).

Contributions

Buffa's research deals with a wide range of topics in PDEs and numerical analysis:{{Cite web |title=Kovalevsky Lecture 2023: Annalisa Buffa |url=https://awm-math.org/awards/kovalevsky-lectures/kovalevsky-lecture-2023/ |access-date=12 February 2023 |website=Association for Women in Mathematics}} "isogeometric analysis, fully compatible discretization of PDEs, linear and non linear elasticity, contact mechanics, integral equations on non-smooth manifolds, functional theory for Maxwell equations in non-smooth domains, finite element techniques for Maxwell equations, non-conforming domain decomposition methods, asymptotic analysis, stabilization techniques for finite element discretizations."[https://www.epfl.ch/labs/mns/ home page for Annalisa Buffa at EPFL]

Recognition

In 2007 Buffa was awarded the Bartolozzi Prize. In 2015 she was awarded the {{ill|Collatz Prize|de}} "for her spectacular use of deep and sophisticated mathematical concepts to obtain outstanding contributions to the development of computer simulations in science and industry" (Laudatio).{{Cite web |url=http://www.imati.cnr.it/index.php/news-3/54-iciam-collatz-prize-awarded-to-annalisa-buffa |title=ICIAM Collatz Prize 2015, news from IMATI |access-date=9 May 2016 |archive-date=10 January 2016 |archive-url=https://web.archive.org/web/20160110170433/http://www.imati.cnr.it/index.php/news-3/54-iciam-collatz-prize-awarded-to-annalisa-buffa |url-status=dead }} In 2014, she was an Invited Speaker at the International Congress of Mathematicians in Seoul with talk Spline differential forms. In 2008, she received an ERC Starting Grant and in 2016 an ERC Advanced Grant. She became a member of the Academia Europaea in 2016.{{citation|title=List of members|publisher=Academia Europaea|url=https://www.ae-info.org/ae/Acad_Main/List_of_Members|access-date=2 October 2020}}
