Research

I am currently a PhD candidate working with Dr. Carlos Martinis at Boston Univeristy. My research focuses on observations of the Earth's upper atmosphere using multiple instruments. I work primarily from the equatorial to midlatitude region (up to a geographic latitude of about 43°, which is where Massachusetts is located) in the longitude region that covers North and South America. I have worked with data incoherent scatter radars, coherent scatter radars, satellites, all-sky imagers, and Fabry-Perot Interferometers. I have combined concurrent measurements from these instruments to get a more comprehensive view of the upper atmosphere.

I started my work on a project about the Midnight Temperature Maximum (MTM), an increase in neutral temperature from about 250-500 km in altitude that occurs around local midnight. We have completed a comprehensive study of this phenomenon with data from the Arecibo Incoherent Scatter Radar (ISR) in Puerto Rico. We characterize the MTM in terms of amplitude, time of occurrence and width and investigate variations with season and solar cycle. Additionally I have worked with the Millstone Hill Radar at the MIT Haystack observatory along with the Arecibo ISR and Fabry-Perot Interfermoters located in the eastern United states

I have also done a lot of work on equatorial spread F (ESF) in the equatorial to midlatitude region. ESF is the name commonly given to plasma irregularities that typically occur after sunset in the equatorial and low-latitude F region. They are attributed to plasma bubbles, depletions in the background plasma that begin to form due to the generalized Rayleigh-Taylor instability. These bubbles can disrupt radio and GPS communications. I am using all-sky imagers (ASI) along with mutltiple other instruments to better understand the variability, morphology, modulations, and 3D structure of ESF. I use multiple Boston University ASIs in Peru, Colombia, and Argentina to study these structures along with other instruments at the Jicamarca Radio Observatory in Peru.

Undergraduate Research

My senior year at Colby I worked with Dr. Murray F. Campbell on a Senior Scholars project. I was looking at the effects that different theoretical dust models would have on modeling high-mass protostellar objects. I used a radiative transfer code written in Fortran by Barbara Whitney for the modeling aspect. I also spent a lot of time studying the electromagnetic theory behind absorption and scattering.

During the summer of 2010 I was at Montana State University. I worked for Dr. Dana Longcope in the Solar Phyiscs department. My project was a comparison of coronal hole locations to open magnetic field regions.

I worked with Dr. David Trilling during the summer of 2009. This was the beginning of the project Explore NEOs. I did ground based observing of near earth objects and wrote the pipeline to analyze the data I was collecting.

In 2008 I worked at UNH for the summer under Dr. Charles Farrugia. I used data from the ACE and WIND spacecrafts to do a comprehensive study of interplanetary coronal mass ejections (ICMEs).
