American Physical Society honors JLab scientists and users

At the 2007 American Physical Society April Meeting, five Jefferson Lab researchers were announced as recipients of 2006 APS Fellowships.

The group represents a cross-section of the Lab's research areas, including experiment, theory and accelerator science. Two Jefferson Lab employees and one member of the Users Group were chosen for work done here. Two other members of the Users Group were honored for work done elsewhere.

The APS Fellowship Program recognizes members who have made advances in knowledge through original research and publication or made significant and innovative contributions in the application of physics to science and technology. They may also have made significant contributions to the teaching of physics or service and participation in the activities of the APS. Each year, no more than one-half of one percent of the current membership of the society is recognized by their peers for election to the status of Fellow. Fellowship nominations are made by APS members in good standing for colleagues they consider worthy of this recognition. Fellowship is therefore a distinct honor signifying recognition by one's professional peers.

Melnitchouk and GriffioenJefferson Lab's 2006 APS Fellows (alphabetically):

Keith A. Griffioen
College of William and Mary, Physics Professor and Department of Physics Chair

Citation: For definitive experimental studies of the spin structure of the proton and neutron, both in the perturbative, deep-inelastic regime and in the non-perturbative resonance region.

"Fellowship in the American Physical Society is truly an honor. I've been blessed with excellent teachers, committed mentors, stellar students, supportive funding agents, hard-working collaborators, fantastic colleagues and a caring family who all share in the credit. We now know precisely how little the quarks contribute to the nucleon spin. In the future, with an upgraded Jefferson Lab, we will know why. I can hardly wait," Griffioen said.

Wolodymyr (Wally) Melnitchouk
JLab Theory Center Staff Scientist

Citation: For his theoretical and phenomenological contributions to the study of the quark structure of nucleons and nuclei, in particular that underpinning the nuclear physics program at Jefferson Lab.

"Jefferson Lab has provided me with a wonderful environment in which to pursue my passion for hadronic physics, and I am very pleased that this award recognizes the importance of the physics being done here. As a theorist, I have always valued the opportunity that the Lab has given me to interact closely with experimental physicists, which I believe is crucial for the continued vitality of our field," Melnitchouk said.
