Research

I graduated from Whitman College in 2006 with a degree in physics and astronomy. During my time at Whitman, I worked as a summer intern on a variety of research projects, including interstellar abundances. While living in Walla Walla, my interest in astronomy and in space also translated to flight training, and a pilot's license.

From the spring of 2007 through the fall of 2008, I worked at the Goddard Space Flight Center. With Dr. W. Dean Pesnell, I studied automated detection methods for solar polar coronal holes. This project developed techniques for using the solar limb for feature identification which traced the location of the Sun's outwardly directed polar magnetic field using a feature on the limb. I also spent some time investigating ways to calibrate solar images taken in the EUV but many years apart. Currently I am still working with polar holes, looking at the centroid locations and integrating ground-based images from the past 30 years.

Since beginning my graduate studies in August of 2008, I have been looking at Solar sequential chromospheric brightenings (SCBs). SCBs are noticed in conjunction with energetic events such as solar flares, prominence eruptions, and coronal mass ejections. Working at the National Solar Observatory in Sunspot, NM, Dr. K.S. Balasubramaniam and I are developing an automated method for detecting and tracking SCBs and the associated flare ribbons within a series of H-alpha images from the ISOON telescope. With a bright-point detection and tracking fully automated, we hope to be able to efficiently identify and track both the evolution of the SCBs which are seen as precursors to the flare and the evolution of the ribbons within the flare itself.

I am very curious about the key processes which drive the solar dynamo and changes in the solar polarity over the solar cycle, and predictive measures for charting the future activity level of the Sun. I continue to be interested in image analysis techniques with an emphasis on automation. My advisor at NMSU is Dr. Jason Jackiewicz.
