Hello all,

Apparently I messed up in my previous attempt to forward Helvi's
announcement (technical reason: the text got included as a "binary"
attachment, due to utf-8 characters).

In any case, below please find the original announcement (which some of
you may have received via other mailing lists and / or the ET mailing
list already. Email lists are getting harder to due to enhanced spam
filters everywhere.).

Yours,
Roland

From: Helvi Witek <hwitek at illinois.edu>

Dear all,

we are inviting applications for a postdoctoral position in numerical
relativity and fundamental physics at the University of Illinois
Urbana-Champaign. The successful candidate will work with Prof. Helvi
Witek and her team, and they will have the opportunity to collaborate
on the Einstein Toolkit/CarpetX software framework.

Applicant should submit their application package

(1) a cover letter,

(2) a curriculum vitae, including a list of publications,

(3) a research statement (limited to 3 pages, 1 inch margin, 11-12pt)
containing a summary of previous and current research, and future
research plans,

(4) contact information for three (3) referees who will be asked to
write letters of recommendation,

by *December 1, 2025*, here:https://my.physics.illinois.edu/join/under
“Postdoctoral Position in Numerical Relativity and Fundamental Physics
with Dr. Helvi Witek – 2026.” The prospective start date of the
position is August 2026.

Please find the detailed announcement below.

Best wishes

Helvi

The Illinois Relativity Group in the Department of Physics at the
University of Illinois at Urbana-Champaign invites applications for a
postdoctoral research position with focus on numerical relativity,
computational astrophysics, and their applications to fundamental
physics.

The successful candidate will join Prof. Helvi Witek and her team to
work on numerical relativity in and beyond general relativity,
including tests of gravity or modeling signatures of dark matter
candidates around black holes. The candidate is intended to partially
work on the Einstein Toolkit/CarpetX software framework and contribute
to its hybrid Monte-Carlo/M1 neutrino transport scheme as part of the
“E=mc^2 ” project. This is a multi-institutional project to develop
numerical infrastructure and methods, with collaborators at Louisiana
State University, Rochester Institute of Technology, University of
Idaho, University of Texas Austin, and the University of Wyoming, and
international collaborators R. Haas and E. Schnetter.

Prof. Helvi Witek’s team is currently home to postdoc Dr. Jay Kalinani,
Visiting Research Scientist Dr. Elena Kopteva, six graduate students
and undergraduate students;
seehttps://witek-gravity-group.physics.illinois.edu. The successful
candidate will become a member of the Illinois Relativity Group which
includes Profs. S. Shapiro, H. O. Silva, N. Yunes, and Research
Professor A. Tsokaros. They will also become part of a vibrant research
community in the Illinois Center for Advanced Study of the University
(ICASU;https://icasu.illinois.edu/) that bridges the Departments of
Physics, Astronomy, Computer Science, Mathematics and the National
Center for Supercomputing Applications (NCSA). ICASU faculty working in
closely related areas include Profs. C. Gammie, G. Holder, J.
Noronha-Hostler, J. Noronha, J. Shelton, and S. Vishveshwara. The
successful candidate will also have opportunities to join the LISA
Consortium (https://lisamission.org) and the Einstein Toolkit
Consortium (https://einsteintoolkit.org).

The candidate should have a strong background in scientific software
development using parallelization frameworks like MPI or in numerical
relativity in and beyond General Relativity. Expertise in GPU
programming is beneficial. Interested candidates must have completed a
Ph.D. in astronomy, physics, or a related field before the start date.

They must submit their application package online
here:https://my.physics.illinois.edu/join/under “Postdoctoral Position
in Numerical Relativity and Fundamental Physics with Dr. Helvi Witek –
2026.” Applicants are requested to submit:

(1) a cover letter,

(2) a curriculum vitae, including a list of publications,

(3) a research statement (limited to 3 pages, 1 inch margin, 11-12pt)
containing a summary of previous and current research, and future
research plans,

(4) contact information for three (3) referees who will be asked to
write letters of recommendation.

The deadline for applications and all letters of recommendation
is*December 1, 2025*, for full consideration. The anticipated starting
date of the position is August 15, 2026, though other starting times
may be negotiated. The position is expected to last for a two-year term
with a potential extension to a third year, conditional on performance
and/or funding availability.

Please contact Prof. Helvi Witek (hwitek at illinois.edu) if you have any
questions about the position itself, or Deanna Frye
(ddebord at illinois.edu) if you have any questions about the application
form.
