Dr. Jackiewicz is a researcher in the field of solar physics. He studies
helioseismology, which involves using solar surface oscillations (sunquakes) to probe the Sun
and determine its internal structure and dynamics. His work employs a
combination of high-resolution mostly space-based observations, rigorous local helioseismology
techniques, large-scale numerical simulations, and quantitative analysis of
synoptic maps of subsurface solar properties. His primary goals are to
address the root causes of solar magnetic activity and quantitatively
establish physical relationships between subsurface properties and the
magnetic activity observed in the solar chromosphere and corona.
Dr. Jackiewicz is working with first-year graduate student
Michael Kirk on a
variety of interesting questions in solar astronomy.
Dr. Jackiewicz is teaching an undergraduate course on The Planets,
ASTR105, for the spring semester, 2009.
