Selected Publications
My group studies the limits of efficient computation. We approach this question from several perspectives, including circuit complexity, proof complexity, pseudorandomness, query complexity, and learning theory.
Quantum speedups require structure or depth
Computational-statistical tradeoffs from NP-hardness
The sample complexity of smooth boosting and the tightness of the hardcore theorem
Fast decision tree learning solves hard coding-theoretic problems

And consider that as the heaps of sand piled on one another hide the former sands,
so in life the events which go before are soon covered by those which come after.
