RESEARCH & OUTREACH

The first nuclear bomb test, codenamed Trinity, was performed in July 1945 at the White Sands Proving Grounds (near Alamogordo, New Mexico). The device, Gadget, was an implosion-type design with a plutonium (Pu-239) core. Trinity was a successful test, and the heat resulting from the 18 kiloton explosion melted the desert sand out to distances of 400 meters from ground zero. The melted sand rapidly cooled to form a glassy layer (up to 2 cm thick) now referred to as trinitite (alternatively, Alamogordo glass). This post-detonation material is a valuable tool in nuclear forensics research. Trinitite incorporated pieces of the Gadget and blast tower, and one of our goals is to identify and characterize the distribution and composition of individual components through geochemical and radionuclide analysis.

Public and peer outreach has always been an important concept to me. Currently, I am co-supervising the training and research projects of two Notre Dame undergraduates. I also feel strongly that science should be widely communicated outside of conferences and scientific journals. Twitter is an excellent venue for real-time sharing and interacting with an audience that includes academic and public users. Some appealing discussion topics have led to longer geological pieces that I post on a personal/research blog.

NON-PROFESSIONAL EXPERIENCE

As part of the LPI internship we toured the Lunar Sample Laboratory at Johnson Space Center

High five!

and got up close and personal with the Lunar Electric Rover

Pat & Ross on the LER

The ND geology department recently instituted a field trip to Michigan's Upper Peninsula (near Marquette, MI). I participated on the 'test' trip in Spring 2011, and was official photographer and an assistant during the October 2011 and October 2012 field trips. Michigan's UP has some spectacular banded iron formations!
