Students and Postdocs

Current students and postdocs:

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.

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, and is currently working on a project to implement finite-frequency shear wave splitting intensity tomography using a model space search approach.

Former students and postdocs:

Miriam Reiss (Postdoc, 2018) worked at Yale on a six-month postdoctoral scholarship from Germany during 2018. She carried out a project on the structure of the lowermost mantle beneath Africa. She is currently a postdoctoral associate in Frankfurt. 

Juan Aragon (B.S. 2017) completed a senior thesis on upper mantle anisotropy beneath the mid-Atlantic Appalachians from SKS splitting measurements at stations of the MAGIC array. He worked with me between 2013-2018 as a field technician and project manager for both the MAGIC and SEISConn experiments. He is currently a technician at the Earthquake Science Center, U.S. Geological Survey.

Andrea Servali (M.S. 2018) worked on the structure and dynamics of the eastern United States, using observations of Love-to-Rayleigh wave scattering. He is currently a data analysis intern at Edmodo.

Andrea Tesoniero (Postdoc, 2017-2018) worked with me on full waveform modeling of lowermost mantle anisotropy. He implemented updates to the AxiSEM3D waveform modeling code to handle arbitrary anisotropy geometries, with applications to modeling of lowermost mantle anisotropy scenarios. 

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.  He is a Research Associate 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 recently finished her degree in geological engineering at the University of Wisconsin, Madison, and is currently a Ph.D. student in geophysics at Stanford University.

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 worked as a postdoctoral researcher at the University of Washington, carrying out wavefield simulations for subduction megathrust earthquakes through the Cascadia M9 Project. She is currently a Research Geophysicist at the U.S. Geological Survey.

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 an assistant professor at Penn State University.

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. Shehas held positions as a science policy fellow at GSA, a AAAS Congressional Science Fellow, and a AAAS Executive Branch 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 a recent law school graduate from 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 recently finished her Ph.D. 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.
