I am an associate professor (sv: universitetslektor) at the Division of Particle Physics at the Physics Department of Lund University in Sweden. I work mainly in the field of High Energy Heavy-Ion Physics, on the ALICE experiment at the LHC. and the PHENIX experiment at RHIC.
Previously, I was a staff scientist (Wigner fellow
Sep 2003 - Sep 2005) with Oak Ridge
National Laboratory. I was a member of the High Energy Reactions/Heavy Ion Collisions group/task, which has a
leading role in the construction and
analysis of e.g. the PHENIX
Muon Arms.
The PHENIX Muon system is designed to study, among other things,
charmonium and bottomonium
spectroscopy and is a vital component in the PHENIX physics
program, also for p+A (proton+nucleus) and spin
physics (p+p). I mainly worked on J/ψ analysis until 2007.
From 2007 to 2014 I was mainly
working on a large acceptance Electro-Magnetic Calorimeter (EMCal - ALICE-USA link)
for the
ALICE experiment at CERN.
In 2005, we had our first
beamtest at Fermilab (which turned out quite well), and in the spring of 2006, the
Technical Proposal was submitted to CERN/LHCC.
We had a second beamtest at CERN SPS and PS in the fall of 2007 (and a third in 2010).
From Jan. 2007 to late Feb. 2009, I was stationed at CERN, to work on the ALICE EMCAL; preparation work for the first installed SuperModules,
mainly electronics and online-related activities. We had four SuperModules (~40% of total EMCAL detector) installed by late July, 2009, for the first LHC run. We installed the remaining six full SuperModules in early 2011, i.e. in time for the second LHC run.
I was stationed at CERN again from April 2010 to March 2012 - mainly working on EMCal operations.
Previously, I was a post-doc with Los Alamos
National Laboratory, in the P-25 group, which is another
of the leading groups for the PHENIX Muon system.
For my PhD thesis, I worked on the PHENIX
Pad Chambers and maintained this
web page. Analysis of Pad Chamber data (with assistance
from other detectors) resulted in the first PHENIX publication:
PRL 86 (2001) 3500,
preprint
nucl-ex/0012008, which was also
the first study of the centrality dependence of charged
particle multiplicity at RHIC energies.
Another topic that I
have a continued interest in is the physics of coherent
peripheral interactions at relativistic heavy-ion colliders.
For a few reviews see e.g. the following preprints:
hep-ph/0112211 and
hep-ex/0201034.

I was born and raised in Sweden.
I'm originally from Jönköping,
and grew up and attended school in Vetlanda. My roots are in
the small villages of Näshult
(wiki)
and
Stenberga
(wiki),
located in the rural province of forests and lakes called
Småland.
I went to Lund
University, and received my PhD at the division of Cosmic and
Subatomic Physics, nowadays merged with particle physics into the
division of Particle Physics.
For my MSc and PhD theses, I worked on the experiments WA98 at the CERN SPS and PHENIX at RHIC, BNL.
After completing my MSc and before starting on my PhD, I
spent a summer
as a student at CERN, working on OPAL.
The analysis I did with secondary vertex reconstruction to estimate B hadron lifetimes later
evolved into
hep-ex/9901017 [Eur.Phys.J. C12 (2000) 609-626].
In the US, I lived in Los Alamos, New Mexico, not too far away from Santa Fe, and then
between Oak Ridge, and Knoxville, in Tennessee.
Two different but both scenic places, Jemez/Rocky mountains
in the Southwest vs Smoky mountains in the Southeast.
