The GW group has been fortunate to have had the active
participation of numerous talented and enthusiastic postdocs and
graduate students in our experimental nuclear physics program
over the past years. Not only has this been crucial for advancing
our research program, but it has also provided the experience and
training necessary for these young researchers to progress in
their respective career paths. Upon leaving GW, all of them have
successfully moved on to positions at least appropriate for their
level of experience, some of them quite prestigious.
In addition, during the summers, the GW group has been able to
offer a number of undergraduates (or beginning graduate students) two- or three-month summer projects to gain exposure
to the research activities of the Experimental Nuclear Physics
Group. Students from GW, from around the country, and from
other parts of the world (France, Scotland, Canada, China, Sri
Lanka and Colombia in recent years) have joined us for these
summer research projects and have come away with valuable
experience and a sense of accomplishment in a forefront research
environment.
We have a long history of mentoring undergraduates, during both
summers and academic years, dating back to the mid-eighties.
Undergraduates have participated with us in our previous
research work at Los Alamos, Bates, Saclay, NIKHEF, and
TRIUMF. One of them (Stuart Wennersten) won the award for
best U.S. undergraduate research in 1992 for his work with us at
LAMPF, and gave a paper at the 7th National Conference on
Undergraduate Research in Salt Lake City in 1993. Many went on
to pursue graduate work in physics or in other scientific or
technical fields. All, we think, derived considerable satisfaction
from their achievements working on state-of-the-art research
projects with the GW group.
Listed below are the postdocs, graduate students, and
undergraduates who have been associated with the GW group
over the past three years, including their principal activities and
years of support. Where applicable, the current status of the
departing members of the group (i.e., students who have
graduated or postdocs whose terms have finished) is also listed.
