II. Educational History
University of California, Berkeley, Ph.D. Nuclear Chemistry, 9/1987-12/1993, Research
Advisor: Joseph Cerny, Dissertation title: Extension of the Tz = -3/2, A = 4n + 1 series of betadelayed proton emitters 65Se and 73Sr, and low energy beta-delayed proton emission from the Tz =
-3/2, A = 4n + 3 nucleus 23Al.
Michigan State University, BS Chemistry, 9/1982-6/1987
III. Physics Research
• Extensive experience in analysis and interpretation of complex decay schemes involving data
from gamma, beta, conversion electron, proton and alpha particles.
• Engaged at all levels of the experimental process as a primary investigator, including the planning,
setup, execution, analysis, and presentation of results in refereed journals and oral presentations. I
have authored or coauthored > 90 journal articles with > 2000 citations.
• Primary areas of research have included:
•
Heavy charged particle decay spectroscopy near the proton drip line.
•
Studies of neutron-rich nuclei near the closed Z =50 and 82 shells using high
resolution gamma detectors.
•
In-depth studies of collective states in the neutron-rich Cd region via gamma, beta
and conversion electron spectroscopy.
IV. Technical development
• Extensive background in use of semiconductor and gas proportional detectors and their
associated electronics and acquisition systems.
• Extensive troubleshooting experience in vacuum and electronic systems.
• Participated in the implementation and commissioning of a new digital spectroscopy acquisition
system for the DSSD. This system consists of 400 MHz flash ADC's, where the shape of the
signal is digitized and recorded. This system is now used routinely for all the detection systems
used for decay spectroscopy at the HRIBF.

2. • Acted as major contributor to the design, commissioning, and experimenter of the focal plane
detector systems at the Recoil Mass Spectrometer (RMS), the Off-line test facility (OLTF) and the
Low Energy RIB Spectroscopy Station (LeRIBSS), including:
• Oversaw the implementation and commissioning of the double-sided Si detector
(DSSD) system located at the focal plane of the Recoil Mass Spectrometer, including
electronics setup, software development, and mechanical designs of the associated
detector chambers.
• Installed and commissioned an improved detector setup at the OLTF consisting of Ge, Si
and scintillator detectors. Setup and implemented the digital electronics and data acquisition
system.
• Aided in the development of the moving tape collector system, used for the study of detailed
spectroscopy following radioactive decay.
•
Designed the computer control system for controlling voltages at the MTOF separator.
• Experience with the operation and design of ion sources and the operation of He-jet systems
• Involved in measurements of neutron-rich nuclei produced via fission of Uranium Carbide with
protons. These measurements served as the first step in the production of neutron-rich beams at the
Holifield Radioactive Ion Beam Facility.
• Proficient with Macintosh, Windows, UNIX and Linux computer systems.
• Experience in design of detector systems including mechanical design through the use of CADstyle programs.
V• Scientific papers
• Author or coauthor on > 100 refereed papers with > 2000 citatiions.
VI• Proposals & conferences
• I have written the scientific portion of the Field Work Proposal from 1997-2012. This proposal
has provided most of the funding for the UNIRIB consortium during this time period.
• I wrote most of the scientific justification for the two proposals that UNIRIB submitted to the
Recovery Act "Applications of nuclear science and technology". One of the two "Construction,
optimization and first experiments: Oak Ridge Isomer Spectrometer and Separator (ORISS)" was
accepted.
• Conceived, organized and acted as the Conference Chair for the "International Symposium on
Proton-emitting Nuclei", which took place at Oak Ridge National Laboratory on October 7-9, 1999.
This is now an ongoing international nuclear physics conference series with follow-up meetings in
Legnaro (2003), Lisbon (2007), Bordeaux (2011) and Langzhou (2015).
• I have presented papers at 16 international nuclear physics conferences including 6 invited talks.
• Served on several organizing committees for international conferences and workshops.
VII• Supervision experience

3. • Supervisory experience with undergraduates via the Professional Internship Program at Oak
Ridge Associated Universities.
• Serving as a liaison to off-site UNIRIB members. UNIRIB is a Consortium of 6 universities that
conduct physics research at the Holifield facility.
• Acting as a mentor to several graduate and undergraduate students from universities in the
UNIRIB consortium.
VIII. Professional Society Affiliations:
• American Physical Society, Nuclear Science Division
• American Physical Society, Southeastern Section
• American Physical Society, Forum on Physics and Society
