I'm a professor in the Mathematics Dept. at M.I.T. I mostly work on quantum computation, quantum information, and quantum complexity, but I am also interested in other areas of theoretical computer science and mathematics.

What areas of pure mathematics research are best for a post-PhD transition to industry?
What do you mean coding theory is not pure math? Coding theory spans a spectrum from extremely pure math to extremely applied. Of course, you do run into the problem that pure coding theory is somewhat different from applied, but if you can find an advisor in the math department who does coding theory, I think this would be an excellent area. |

point in polytope
It needn't actually double the number of constraints; you can replace the inequality $\lambda_i \geq 0$ by $\lambda_i - x \geq 0$, to get the same number of constraints and one more variable. I expect you'll still take a performance hit, but less of one. |

Your nice answer makes me glad I bumped it (I fixed a broken link). |

Largest graphs of girth at least 6
@Brendan: the reason I came upon this question was looking at sequence A072567 in the Online Encyclopedia of Integer Sequences. The $m$th term is the number of edges in the largest bipartite subgraph of $K_{m,m}$ (which is tangentially related to a quantum game I'm looking at). So after you've checked this table, if all your bipartite graphs for even $n$ are split $n/2,n/2$, you could easily extend this sequence. |

Largest graphs of girth at least 6
Some numerology: 15, 27, and 43 are one more than 14, 26 and 42, respectively. For these numbers, the unique optimum bipartite graph of girth 6 is based on the point-line incidence structure of a projective plane with $n= 2(q^2+q+1)$ and $e = (q+1) (q^2+q+1)$. |

Quantum PCP Theorem
One more comment: besides trying to retrace Dinur's proof, there are indeed other ways of approaching the quantum PCP conjecture: see this recent paper of Matt Hastings. |
