UI researcher named 2002-03 distinguished lecturer by American Physical
Goree, professor of physics and astronomy in the University of Iowa College
of Liberal Arts and Sciences, has been selected by the American Physical Society's
(APS) Division of Plasma Physics as one of six Distinguished Lecturers in
Plasma Physics for 2002-2003. As an APS Distinguished Lecturer, he will travel
across the country lecturing at institutions of higher learning under the
Plasma Physics Travel Grant Program funded through the U.S. Department of
This is the second consecutive year that a UI researcher has received the
APS honor, as Robert Merlino, professor of physics and astronomy, was named
an APS Distinguished Lecturer in Plasma Physics for 2001-02.
Goree, who earned his doctorate from Princeton University in 1985 and joined
the UI faculty the same year, has research interests in the field of experimental
In May 2002, he received a $700,000 NASA grant to use the International
Space Station (ISS) to study the motion of waves through crystalline lattices
-- the patterns of regularly arranged atoms that comprise such materials as
iron. His experiment, "Optically-excited waves in 3-D dusty plasmas,"
will be carried aboard the ISS sometime after 2006.
His NASA grant and a related proposal (both written by Goree and Professor
Alexander Piel of the University of Kiel, Germany) were ranked by peers as
first and second among some 117 proposals submitted by scientists from around
the world in the first such international competition of its kind. Goree's
ISS experiment may provide scientists with a better understanding of how a
crystalline lattice conducts sound waves produced by a supersonic disturbance,
similar to the sonic shock created by a fighter jet moving through the air.
In March, Goree, together with experimenters from Germany, Russia, and France,
conducted the first physical sciences experiment to be done aboard the ISS.
The purpose of this Plasma Crystal Experiment was to observe how crystals
form in space, free of Earth's gravity.
