Distributed Machine Learning: Today’s BIG computing problems are solved, not with super-computers, but rather with thousands of smaller computers working together. This requires redesigning classical algorithms, originally designed for the serial computing age, and applying them to distributed computing environments. My research focuses on doing just that, for machine learning algorithms (and thus for other stochastic optimization problems).
On Brain Maps: I am interested in the methodological problems of brain imaging: How to generalize findings from a group study to a “typical brain”? How to analyze imaging genetic studies where the number of relations to study is in the Billions ? How to account for the bias introduced by search-and-select methods such as region selection in social neuroscience (“Voodoo correlations”), and searchlight analysis in multivoxel pattern recognition?
High Dimensional Statistical Process Control: Modern day quality control does no longer consist of the variation of a single attribute over time. Production lines today have hundreds and thousands of sensors monitoring performance. It so happens, that the problem of quality control has applications in any monitoring problem. This include cyber security alerting systems, patient monitoring, internet of things (IOT), etc.
Statistical arguments and the philosophy of science: What makes a statistical finding “convincing”? Are all arguments (Bayesian, Frequentist, Fiducial,…) adequate for all problems?
I am actively recruiting PhD students and Post-docs with strong mathematical background to work on projects related to machine learning.
