Preserving patient privacy in biomedical data analysis
(Massachusetts Institute of Technology, 2015)
The growing number of large biomedical databases and electronic health records promise to be an invaluable resource for biomedical researchers. Recent work, however, has shown that sharing this data- even when aggregated ...
Fast and scalable solvers for the Helmholtz equation
(Massachusetts Institute of Technology, 2015)
In this thesis we develop a new family of fast and scalable algorithms to solve the 2D high-frequency Helmholtz equation in heterogeneous medium. The algorithms rely on a layered domain decomposition and a coupling between ...
Bounds on extremal functions of forbidden patterns
(Massachusetts Institute of Technology, 2015)
Extremal functions of forbidden sequences and 0 - 1 matrices have applications to many problems in discrete geometry and enumerative combinatorics. We present a new computational method for deriving upper bounds on extremal ...
The structure of auctions : optimality and efficiency
(Massachusetts Institute of Technology, 2014)
The problem of constructing auctions to maximize expected revenue is central to mechanism design and to algorithmic game theory. While the special case of selling a single item has been well understood since the work of ...
