I received both my undergraduate education and Ph.D. from
the University of
Chicago. My primary
research interests are the acceleration of solar and galactic cosmic rays and
the study of the heliospheric magnetic field by observation of the propagation
of cosmic rays through this field. From 1999-2001, I served as Program Director
for Solar Terrestrial Research at the National Science Foundation in Arlington, Virginia.
At Delaware I established a program of high altitude balloon flights
from northern Canada designed to
give graduate students hands-on experience with modern research equipment and
field operations on a timescale consistent with thesis research. Regular
flights are conducted with an apparatus to study the time-dependence of the
intensity of cosmic electrons and positrons. I am now a member of the
collaboration building the IceCube Neutrino
Observatory at the South Pole, and also an active participant in the Delaware neutron monitor program, including
the Spaceship Earth collaboration.
