<div>Dear Colleague:<o:p></o:p></div>
<div><o:p> </o:p></div>
<div>We are
deeply saddened to inform you of the passing of <br>
Dr. William Bradford
(Brad) Tippens in the early morning of <br>
March 15, 2011. Since 2000,
Brad had served as the Program <br>
Manager for the Medium Energy Program in
the Office of <br>
Nuclear Physics of the DOE Office of Science. <o:p></o:p></div>
<div><o:p> </o:p></div>
<div>Brad
received his Ph.D. degree from Texas A&M University <br>
in 1984 in
nuclear physics, working on a series of polarized <br>
nucleon-nucleon
experiments for his doctoral dissertation. <br>
Following receipt of his
doctorate, Brad was a research <br>
associate at the University of Virginia;
while there he was <br>
involved in the MEGA experiment and the TRIPLE
collaboration <br>
at Los Alamos National Laboratory. In 1989, he accepted
a <br>
research physicist position at the University of California, Los
Angeles. <br>
In this position he had responsibility for the design,
presentation, <br>
mounting, and execution of two experimental programs at
the <br>
Alternating Gradient Synchrotron at Brookhaven National
Laboratory. <br>
The first of these two programs involved a precision test
of charge <br>
symmetry and the production of the eta particle. The second
was <br>
an ambitious program in baryon spectroscopy using the Crystal Ball
detector. <br>
These scientific activities resulted in a number of journal
publications, <br>
and contributions to conference proceedings.<o:p></o:p></div>
<div><o:p> </o:p></div>
<div>In
2000, Brad joined the Nuclear Physics Division in what was then the
<br>
Office of High Energy and Nuclear Physics, where he assumed the
<br>
position of Program Manager for the Medium Energy Program. Brad <br>
was a
tireless supporter of his program, which he held to the highest
<br>
standards as those in the program know well. Among his many
<br>
accomplishments were the management of the 6 GeV research program <br>
and
the developing 12 GeV program at Jefferson Laboratory, initiation of
<br>
the program to measure the spin components of the proton at Brookhaven
<br>
National Laboratory, and support of other important efforts including a
<br>
Drell-Yan experiment and a neutrino oscillation experiment at Fermi
<br>
National Accelerator Laboratory, atom trapping development aimed
<br>
towards an atomic electric dipole moment measurement, the physics
<br>
program with the BLAST detector at the Massachusetts Institute of
<br>
Technology Bates facility, and experiments at several European
laboratories. <br>
He administered approximately 45 university grants,
large and small, <br>
with a strong vision to help researchers, and
especially students, accomplish <br>
important science. Within the DOE, he
took on a number of additional <br>
responsibilities, including management
of the Nuclear Physics Outstanding <br>
Junior Investigator program, serving
as the point-of-contact for education <br>
matters for Nuclear Physics, and
taking part in the early efforts to modernize <br>
electronic workflow
within the Office of Science.<o:p></o:p></div>
<div><o:p> </o:p></div>
<div>Brad
made his home near Columbia, Maryland. He is survived by his wife,
<br>
Tabitha, and three sons, Jonathan, Nathaniel, and Daniel. Funeral
plans are pending.<o:p></o:p></div>
<div><o:p> </o:p></div>
Brad will be greatly missed by those in the Office of Nuclear Physics.
