Professor Park has been studying neutrino interactions for decades. She has been interviewed recently by the Gazette to answer questions like:

What are the main differences between the neutrino research being done at SNOLAB and IceCube?
How does it work? Why is it important that IceCube be buried in ice?
What are cosmic-rays and how do they differ from neutrinos in their behaviour?

When a neutrino interacts with molecules in the clear Antarctic ice, it produces secondary particles that leave a trace of blue light as they travel through the IceCube detector. [Credit: Nicolle r. Fuller/NSF/IceCube]

The IceCube Laboratory at the Amundsen-Scott South Pole Station, in Antarctica, hosts the computers collecting raw data. Due to satellite bandwidth allocations, the first level of reconstruction and event filtering happens in near real time in this lab. Only events selected as interesting for physics studies are sent to UW-Madison, where they are prepared for use by any member of the IceCube Collaboration. [Credit: Felipe Pedreros, IceCube/NSF]
