Hi! I'm an astrophysicist in the High Energy Astrophysics Division at the Smithsonian Astrophysical Observatory (SAO), part of the Harvard-Smithsonian Center for Astrophysics.

My current research focuses on interacting galaxies and the evolution of galaxies in galaxy groups and clusters. I primarily analyze X-ray data taken with the Chandra and XMM-Newton X-ray Observatories, but also use radio, optical and infrared data to help understand how galaxies and their central black holes interact with each other and with the hot gas that surrounds them. NGC 6872 is one of my favorites.

My picture (right) is from a recent trip to the beautiful Magellan Telescopes .

In addition to my research, I coordinated the SAO Astronomy Intern Program for undergraduate students from 2008 through 2014, and still act as a resource for the program. For more information about the SAO Summer Intern Program and how to apply, please see the program website .

Applications are now open for the Summer 2016 SAO Intern Program at the CfA and all are looking forward to another great summer!

Calendars for the 2014 SAO Summer Astronomy Intern Program are:

June 2014

July 2014

August 2014

Tours and social activities are added throughout the summer, depending on the interests of the group.

Here are links to a few basic tutorials on programming and software that are often used in astrophysics research. Here are also some notes and links of interest for our discussion of research ethics.

Interns from our Astronomy Intern program host the 2014 Summer Colloquium Series , presented by CfA scientists and designed to give summer interns and other junior researchers a broad introduction to research here at the CfA. All are welcome to attend. Interns from our sister CFA Solar REU program host a series of talks on solar research that our interns are invited to attend.

Our 2014 SAO Interns reported their research results to the CfA community at the 2014 Astronomy Intern Symposium , and all presented their work at the 2015 January meeting of the American Astronomical Society. Here is a list of the 2014 Summer Project Abstracts that are being presented at the 225th meeting of the American Astronomical Society, January 2015.
