Langtangen received Cand.Scient. (1985) and Dr.Scient. (1989) degrees
in mechanics at the Department of Mathematics, University of
Oslo. He joined SINTEF Applied Mathematics (formerly SI,
Center for Industrial Research) in 1990, and got a position
as Assistant Professor of fluid mechanics at the Department of
Mathematics in 1991. During the first half of the 1990s, he worked
partly at SINTEF and partly at the University. His main areas of research
were mathematical modeling based on continuum mechanics,
numerical methods for partial differential equations, and programming
techniques for numerical software. The latter subject was particularly
explored through the development of Diffpack, an object-oriented,
comprehensive programming environment for solving partial differential
equations. Langtangen co-founded the company Numerical Objects A.S.
in 1997 for commercializing Diffpack (the technology was in 2003 taken
over by inuTech GmbH in Germany).
In 1998, Langtangen became a full Professor of Mechanics at the
Department of Mathematics, University of Oslo. In 1999 he moved to
Aslak Tveito's Scientific Computing group at the Department of
Informatics. As a member of this group, he took up a full research
position at Simula in 2001, being on 80% leave from the University of
Oslo. Langtangen held a part-time position as NorFA Professor of
Scientific Computing at the Department of Information Technology at
Uppsala University 1999-2002. He has also served as a scientific
advisor and computer science consultant for numerous projects
in Norwegian industry.
Langtangen has authored three books, co-authored one book, and
co-edited three books. He has over a hundred peer reviewed research
works and has contributed to about 100 talks at conferences (including
seven keynote presentations).
The publications cover fluid flow, elasticity, wave propagation, heat transfer,
finite element methods, stochastic differential equations, object-oriented
programming, and mixed high-low level language programming .
Langtangen serves as Associate Editor of seven international journals
(including prestigious journals such as SIAM J. on Scientific Computing,
BIT Numerical Mathematics, and Advaces in Water Resources).
He has also been a member of the organizing or scientific committees
of a dozen international conferences. At 18 occasions he has been
member of PhD committees and acted as first or second opponent.
On the teaching side, Langtangen has supervised about 60 master students,
14 PhD students, and initiated ten new University courses. His courses
often migrate new methods and working styles from research to all levels of
the educational system. The most recent course, aimed at 200+
beginning students, blends classical mathematics, numerical methods, and
programming, with applications to diverse fields such as physics, biology,
In 2005, Langtangen and co-workers at Simula applied for a Norwegian Center
of Excellence, the largest and most prestigious research grant in Norway. The
center was awarded in 2007 and named Center for Biomedical Computing,
with Langtangen as director. The center is hosted by Simula and contains the
Department of Scientific Computing along with collaborating groups in Norway
and abroad. The main purpose of this center is to conduct top international
research on numerical methods and numerical software for challenging
applications to biomedicine (including electrophysiology of the heart, flow
of blood, cerebrospinal fluid, and air in humans, fluid-structure interactions,
and evolutionary biology). The center also features geoscientific applications,
fully funded through a substantial collaboration with Norway's largest industrial
company, Statoil. For more information on the center's scientific
achievements, visit the home page above and look at the annual reports.
