Instructors and Postdocs

Ali Ahmed

Postdoctoral Associate

Ali Ahmed received his PhD in electrical engineering from Georgia Institute of Technology in 2013. His research interests include inverse problems in signal processing and machine learning using tools from probability and optimization theory. In particular, he has been working on efficient sampling schemes in array processing, blind deconvolution using convex methods, and randomized algorithms for non-convex optimization.


Dima Batenkov

Postdoctoral Associate

He obtained his PhD from the Weizmann Institute of Science, Israel. His research interests include mathematical theory and applications ofsuper-resolution, and more generally inverse problems involving piecewise-smooth models. This is an exciting subject with interesting open questions, both theoretical and algorithmic, and a great number of possible applications. He is also interested in the theory and applications of sparse representations.


Pawan Bharadwaj

Postdoctoral Associate

Pawan finished his PhD program in Geophysics at Delft University of Technology (TUDelft), the Netherlands. In 2012, he obtained a Master of Science degree in Geophysics from Indian Institute of Technology (Indian School of Mines), Dhanbad, India. His research interests are in seismic imaging, inverse problems, interferometry and signal processing. Besides research, he enjoys badminton, inline skating, longboarding and travelling.


Niels Grobbe

Postdoctoral Associate

Dr. Niels Grobbe is a postdoctoral associate in the ICG at the MIT Mathematics department, as well as in the Earth Resources Laboratory. Previously, he obtained his B.Sc. degree in Earth Sciences (major in Geophysics), and his M.Sc. degree in Geophysics from Utrecht University in the Netherlands. He obtained his Ph.D. degree in (Applied) Geophysics from Delft University of Technology in the Netherlands. His primary research interests encompass (geophysical) imaging and inversion across scales, numerical modeling of complex wave phenomena, uncertainty analysis, physics of porous media, coupled poroelastic and electromagnetic fields, interferometry, and multi-physics approaches.


Yunyue Elita Li

Visiting Research Associate

Yunyue (Elita) Li is a visiting research associate with ICG. She obtained her bachelor's degree from China University of Petroleum, Beijing in 2008. She joined Stanford Exploration Project for her master's and PhD degree, working with Biondo Biondi. Her research field broadly includes computational geophysics and inverse problems, with particular interests in seismic imaging, velocity model building, reservoir characterization and sparse reconstruction. She is now on the tenure-track at NU Singapore.


Carlos Perez-Arancibia

Applied Math Instructor

Carlos is Instructor in Applied Mathematics at the Department of Mathematics at MIT. He obtained his BSc and MSc degrees in Engineering and Computational Mathematics from the Pontificia Universidad Catolica de Chile, and his PhD in Applied and Computational Mathematics from the California Institute of Technology (Caltech). His research interests include wave phenomena, integral equations, high-order PDE solvers, numerical analysis and applied mathematics in general.


Matthias Taus

Postdoctoral Associate

Matthias received his PhD from the Institute for Computational Engineering and Sciences at the University of Texas at Austin in 2015. He is originally from Austria where he got his Bachelor's and Master's degree from the University of Technology in Graz. Matthias' research is focused on numerical methods for solving PDEs. These methods include Finite Element Methods, Spectral Methods, and Integral Equation Methods for which Matthias is working on accurate and fast solution techniques.


Graduate Students

Matt Li

Matt is a graduate student in the Computational Science and Engineering program. He received his BASc in Engineering Science (Aerospace) from the University of Toronto in 2013. In addition, he also completed his MASc in 2015 focusing on numerical methods for high dimensional function approximation and integration. Matt's research interests include uncertainty quantification, full-waveform inversion, signal processing, and numerical analysis. Despite all evidence to the contrary he still believes that the Toronto Maple Leafs are going to win the Stanley cup this year.


Lucas (Bram) Willemsen

Bram is a graduate student in Geophysics. He is a Dutch citizen and obtained his BSc in Earth Sciences at Utrecht University in the Netherlands. Before coming to MIT he got his MSc in Mining and Geotechnical engineering at Luleå University of Technology (LTU) in Sweden. His academic interests include Full Waveform Inversion and Imaging. Outside of work he practices Taekwondo, plays squash and also likes to get a drink with friends.
