Zhitu Ma

I am a postdoc working closely with Colleen Dalton. My primary research interest is to understand the Earth’s lithosphere. Seismological properties such as elastic velocities and anelastic attenuation provide key constraints on its thermal structure, chemical composition and rheology. My goal is to develop new approaches to improve seismic models in order to make progress in determining these properties and how they reflect geodynamic processes and Earth’s evolution.

 

 

Karen Godfrey

I started my graduate studies at Brown in Fall 2014, after having received my M.S. in 2011 (Southern Illinois University at Carbondale), and spending some time in the oil industry. I am most interested in using seismic sources to image Earth structure. My current research involves using surface wave tomography to study the upper mantle beneath the Indian Ocean. By understanding the seismic velocity structure of oceanic upper mantle, we can place constraints on the evolution of oceanic lithosphere.

 

 

Roque Soto Castaneda

I’m a Class of 2016 undergraduate concentrating in Geology-Physics/Math. My research interests involve learning about the Earth through the observation of seismic waves. In my projects, I often image the structure and composition of the Earth’s crust and upper mantle using various methods of analyzing seismic records, such as surface wave and body wave tomography using both proximal and teleseismic sources. My most recent project is focused on analyzing Earthscope USArray Transportable Array data for surface waves and creating and interpreting phase velocity maps using a two-station inversion method.

 

 

Chris Carchedi

I'm a Class of 2017 undergraduate concentrating in Geology-Physics/Mathematics and working alongside Colleen Dalton and Tim Herbert. My research interests span seismology and structural geology, as I seek to discover and understand what lies below. Past work has involved analyzing seafloor evolution across the Atlantic. Currently, I am exploring the variance of seafloor spreading rate with time through the lens of the magnetostratigraphic record.
