My broad scientific goal is to understand how ocean circulation influences climate through the movement of heat and carbon around the globe. I am particularly interested in how subsurface intermediate and deep waters transmit signals from the high latitudes into the equatorial regions where they propagate change from depths greater than 700 m up to the surface ocean and atmosphere. I apply a multi-proxy approach, including organic geochemical techniques, stable isotope analysis, radiocarbon, nannofossil abundance counts, and trace metal geochemistry. I use these tools to understand changes in communication between surface, intermediate, and deep waters and the impact of these changes on sea surface temperature, phytoplankton productivity, and carbon exchange with the atmosphere during the Pleistocene using deep-sea sediment cores. I am also a seagoing oceanographer and have participated in three previous ocean coring expeditions, including International Ocean Discovery Program Expedition 363 that sailed in the fall of 2016.
My interest in marine geology and paleoclimate was cemented during my undergraduate education. Despite attending Washington University in St. Louis in land locked Missouri, my senior thesis research on fluvial tufa deposits and participation in the Pathfinder Program inspired me to work with marine records, which can provide long and continuous records of past climates. In graduate school, I worked with marine sediment cores from the eastern equatorial Pacific, completing my Ph.D. with Dr. Timothy Herbert at Brown University in August 2016.

At Brown University, I led a volunteer outreach program at Vartan Gregorian Elementary School, teaching weekly science lessons to underserved second grade students. I taught, designed lessons, and organized graduate students to rotate in each week to teach hands-on lessons on the rock cycle, weather, properties of gases, solids, and liquids, and much more. In addition, I participated in a biweekly survey program of Narragansett Bay working with the local Save the Bay (link: https://www.savebay.org/) group during the summer.
