This summer, many new faces join the department, and we congratulate Hamed Owladeghaffari on his promotion to research scientist.
Yu Liu joins the MIT Center for Global Change Science (CGCS) as a research scholar. She interprets global measurements of anthropogenic greenhouse gases and ozone depleting atmospheric gases selected from the tracer gases observed in the MIT led AGAGE global network. She also applies state-of-the-art 3-dimensional Eulerian and Lagrangian atmospheric circulation models with statistical techniques (Bayesian, kalman filter and etc.) to solve the involved inverse problems. Her primary goal is to determine emissions, transport rates and mechanisms, loss rates and mechanisms, ozone depletion and radiative forcing by these gases at the country level to hemispheric level around the world.
Liu was awarded a PhD in environment science from Swiss Federal Institute of Technology in Zürich (ETH) and MSc in Cartology and Geographic Information System(GIS) at Beijing Normal University.
Louise Maubant is a postdoc joining the Frank group. Maubant is a geophysicist working on observing and understanding transient slip and the seismic cycle in subduction zones. During her PhD, she studied the seismic cycle along the Mexican subduction zone by combining InSAR and GPS data. One of the main challenges of her research was to decompose the signals contained in the InSAR time series, in order to extract the tectonic signal from the atmospheric signal. Using methods such as blind source separation (BSI), she showed that it was possible to observe deformation due to slow slip events (SSE) in the Guerrero region, but also aseismic deformation due to large-scale interseismic loading. The integration of InSAR data has demonstrated the importance of having geodetic observations with the best possible spatial coverage once again. She is now studying the Hikurangi subduction by conducting a large-scale study of the seismic cycle in this region using InSAR, GPS and seismological data.
Zhendong Zhang is a new postdoc in the Nakata group. He was a postdoc research associate at Princeton University before joining MIT ERL. His research interests include global mantle discontinuities, numerical solutions for pseudo-acoustic wave equations, finding optimal objective functions for elastic FWI, deep-learning aided regularization for multiparameter estimation and surface wave inversion.
Brendan Field is a lecturer in EAPS. His work will focus on developing interactive digital methods to tutor students in introductory science. He is interested in designing algorithms that make decisions to foster student understanding, confidence, and critical scientific thinking. Brendan has previously taught high school physics for 18 years. He has coached nationally-competing high school science bowl and science olympiad teams. Prior to teaching he worked for 5 years as a computer programmer in the Harvard atmospheric chemistry modeling group.
Brendan earned a BA in physics from Oberlin College, an MS in physics at the University of Colorado, and a MAT in teaching and curriculum from the Harvard Graduate School of Education.
Cypress Frankenfeld joins the Schlosser group (CGCS) as a software engineer. He holds a BS in Engineering with a Concentration in Computing from Olin College of Engineering. He’s previously worked on 3D mobile CAD at Onshape, and security and authorization at HubSpot. At EAPS, he’s helping researchers by designing and programing tools to help communicate research findings to the public, or other stakeholders. These tools include code to process data, databases to store the data, REST APIs to access data, and frontend website or mobile app code to display and visualize that data either statically or interactively.
