About my work
After having studied in Stuttgart and Heidelberg (Germany),
having obtained a Ph.D. in Heidelberg, briefly working at
ETH Zürich (Switzerland), and three years as a
Postdoctoral Research Fellow at the University of Texas at
Austin (with joint positions at both the
Computational Sciences and Engineering
and at the Institute for
Geophysics), I am now a Professor in the Department of Mathematics
at Texas A&M University.
I consider myself a mathematician and computational
scientist. My present field of work is the numerical
solution of inverse problems for partial differential
equations, as well as of various other partial differential
equations by adaptive finite
element methods. If you are interested in some more
details about this, take a look at
this page. My work comprises
more than only that, but it may give you an impression.
There is also a page with a
picture gallery, for those who
admire the arts...
The deal.II Library
deal.II is the
program library which the finite
element programs I write are based on. I am the
principal author and maintainer of this publicly available
Open Source library written in C++ for the numerical solution
of partial differential equations.
Growing over time, we now have roughly 1000 downloads of
the library as well as several thousand hits on our webpage
each month. deal.II is also part of the computing
industry standard SPEC
CPU2006 benchmark, and my co-authors and I have received
the J. H.
Wilkinson Prize for Numerical Software for its
creation. It is used worldwide, and has been used for
numerical results in more
than 400 scientific papers.
Some of the features of the library are grid management
with hierarchically refined grids and hanging nodes
in one, two, and three space dimensions, a unit
managing degrees of freedom for arbitrary linear
(1D), quadrilateral (2D) or brick (3D) elements, support for
multithreaded and parallel distributed cluster computing, and
a library of different finite elements. Too many other things
are also in there to mention them all here, check it out yourself if you
want to know more about it.
I wrote the basic blocks of this library in
1998 for my thesis, but it has been greatly
extended since, by me and others in the Heidelberg group, and
dozens of other people around the world. Presently,
it has about 600,000
lines of code, and extensive documentation (if printed, more
than 5,000 pages).

Of course, even better would be to come see my directly in
room 507D of the Blocker building on campus. If you have
questions you can call
