UW Theory Highlights

Kira Goldner is named a Microsoft Research PhD Fellow.

The students of the UW theory group had an impressive presence at SODA 2017. Becca Hoberg and Thomas Rothvoss demonstrate A Logarithmic Additive Integrality Gap for Bin Packing; Cyrus Rashtchian and Paul Beame prove new results on Massively Parallel Similarity Join, Edge-Isoperimetry, and Distance Correlations on the Hypercube; Alireza Rezaei and Shayan Oveis Gharan develop new Approximation Algorithms for Finding Maximum Induced Expanders.

Thomas Rothvoss is named a Packard Fellow.

Shayan Oveis Gharan named one of the "10 Scientists to Watch" by Science News.

Anna Karlin elected to the American Academy of Arts & Sciences.

Amos Fiat, Kira Goldner, Anna Karlin, and Elias Koutsoupias characterize the optimal auction in the "FedEx setting", further demonstrating the importance of "ironing" and LP duality in mechanism design.

Alireza Rezaei, Shayan, and Nima Anari design efficient MCMC algorithms for sampling from homogeneous strongly Rayleigh measures, a generalization of k-determinantal point processes.

Anup Rao wins the 2016 SIAM Outstanding Paper Prize for his work with Boaz Barak, Mark Braverman and Xi Chen on how to compress interactive communication.

Elaine Levey and Thomas show how the Lasserre SDP hierarchy can be used to design new approximation algorithms for the classical problem of min-makespan scheduling with precedence constraints.

Rong Ge, Qingqing Huang, and Sham Kakade design new efficient algorithms for learning mixtures of Gaussians in high dimensions.

Makrand Sinha and Anup discover a simpler proof that information complexity is not the same as communication complexity.

Siva Ramamoorthy and Anup give new techniques to compress communication protocols when the amount of communication is asymmetric.

James R. Lee, Prasad Raghavendra, and David Steurer win a best paper award at STOC 2015 for proving the first super-polynomial lower bounds on semidefinite extension complexity.

By proving a generalization of the Kadison-Singer conjecture, Shayan Oveis Gharan and Nima Anari give an improved bound on the integrality gap of the classical Held-Karp relaxation for the Asymmetric Traveling Salesman Problem.

Thomas Rothvoss wins the best paper award at STOC 2014 for proving lower bounds on the extension complexity of the matching polytope. Lance Fortnow calls it the "complexity result of the year."
