Students and Postdocs

Current students:

Neala Creasy started as a graduate student at Yale in Fall 2014. She is interested in the structure and dynamics of the lowermost mantle from both a seismological and a mineral physics perspective. Her current projects center on observations and models of seismic anisotropy in the D” layer at the base of the mantle. She is a current NSF Graduate Research Fellow.

Andrea Servali started as a graduate student at Yale in Summer 2016. He is working on the structure and dynamics of the eastern United States, particularly beneath the MAGIC experiment in the mid-Atlantic Appalachians.

Puskar Mondal started as a graduate student at Yale in Fall 2016. He has interests in theoretical and computational seismology, seismic anisotropy, and seismic tomography.

Juan Aragon is an undergraduate student who is currently completing a senior thesis on upper mantle anisotropy beneath the mid-Atlantic Appalachians from SKS splitting measurements at stations of the MAGIC array. He has been working with me since 2013 and has been heavily involved in both the MAGIC and SEISConn experiments.

Former students and postdocs:

Heather Ford (Postdoc, 2013-2016) worked with me on observations, models, and interpretations of seismic anisotropy in the D” layer at the base of the mantle, as well as observations of mid-lithospheric discontinuities beneath the North American continent. She is currently an assistant professor at the University of California, Riverside.

Colton Lynner (Ph.D. 2015) worked with me on his thesis research on the structure and dynamics of the sub-slab mantle (upper mantle, transition zone, and uppermost lower mantle) and the anisotropic structure of the lowermost mantle beneath Africa. As of January 2016, he is a postdoctoral researcher at the University of Arizona.

Caroline Eakin (Ph.D. 2015) worked with me on her thesis research on the dynamics of the flat slab subduction system beneath Peru, using data from the PULSE project along with geodynamical modeling techniques. She was a research fellow at the National Oceanography Centre/University of Southampton from 2015-2016, and recently started a faculty position at the Australian National University.

Lauren Abrahams (IRIS summer intern, 2015) worked with me and postdoc Heather Ford on a project to explore the anisotropic structure of the lithosphere beneath the Eastern US. A paper describing her project is currently in preparation. Lauren will soon finish her degree in geological engineering at the University of Wisconsin, Madison.

Erin Wirth (Ph.D. 2014) worked with me on her thesis research on the structure and dynamics of the subduction zone mantle wedge and the continental lithosphere. She is currently a postdoctoral researcher at the University of Washington, carrying out wavefield simulations for subduction megathrust earthquakes through the Cascadia M9 Project. 

Brad Foley (Ph.D. 2014) worked with me on his minor discourse project from 2009-2010, measuring source-side splitting for earthquakes originating in the Tonga subduction zone. Brad’s project culminated in a paper that appeared in GRL in 2011. Brad is currently a postdoctoral fellow at the Department of Terrestrial Magnetism, Carnegie Institution of Washington, and will be moving to an assistant professor position at Penn State in 2016.

Karen Paczkowski (Ph.D. 2012) worked on her final thesis chapter with me, running a series of 3-D finite element models to simulate sub-slab mantle flow in subduction systems with migrating trenches. This work was being carried out in collaboration with Laurent Montesi at UMD and was published in 2014 in papers in GRL and G^3. Karen spent a year working in industry, doing fluid dynamics simulations for an aeronautics company in CT, and then spent a year as a postdoc at UMD. She was a science policy fellow at GSA and is currently a AAAS Congressional Science Fellow.

Xiaobo He (postdoc, 2010-2012) worked with me on characterizing and interpreting anisotropy in the D” layer at the base of the mantle; see his 2011 paper in G^3 on D” anisotropy beneath the northwestern Pacific. Xiaobo is currently an assistant professor at Zhejiang University.

Jenny Hanna (M.S. 2011) worked with me on the characterization of shear wave splitting in subduction systems, including the Izu-Bonin-Marianas and Alaska subduction zones. Her paper on SKS splitting in Alaska was published in Tectonophysics in 2012. Jenny is currently in law school at Quinnipiac University. 

Kimmy McCormack (summer intern, summer 2011, hosted through the IRIS Summer Internship Program) worked with me and Erin Wirth on a project that involved anisotropic receiver function analysis at stations located in the Ryukyu arc. A manuscript describing Kimmy’s project was published in GRL in 2013. Kimmy is currently a graduate student in geophysics at the University of Texas at Austin.

Emme Johnston (undergraduate researcher, summer 2009) worked with me and the late Paul Silver on a project to explore the potential for subduction initiation on oceanic fracture zones. This work was published in Tectonophysics in 2011. Emme also worked with me on the research for her senior thesis at Mt. Holyoke College, measuring SKS splitting at temporary stations deployed in South Carolina (described in this paper). Emme is an accomplished dressage rider and is currently a working student at a stable in North Carolina.
