I'm a PhD student in biomathematics, working on stochastic individual-based models of evolution in spatially structured populations. My other interests include cryptography, programming games and puzzles, photography and graphic design.


I'm the main author and maintainer of the Stack Overflow Unofficial Patch (SOUP), a user script for browsers with GreaseMonkey-compatible user script support (Firefox, Chrome, Opera, possibly Safari) that fixes or works around a number of outstanding issues with the Stack Exchange user interface.

I tend to answer a lot more questions than I ask. Some answers I'm rather proud of:

CC-Zero Please consider any (original) code I post to Stack Overflow and other Stack Exchange sites to be released under CC-Zero unless stated otherwise. You may do whatever you want with it and don't have to credit me in any way, although of course that would be nice.

comment Recover from compromised shares with Shamir Secret Sharing
+1. Of course, it's worth noting that the dealer still needs to be trusted; a malicious dealer could construct their polynomial with a non-zero constant term, thereby changing the secret (potentially to one of their choosing, if they can guess the original secret).

comment Is TripleDES 168bit vulnerable to Differential Cryptanalysis?
@owlstead: Agreed. Not only is it full of both factual and grammatical errors, but most of the text, or at least the more fluent parts of it, appears to be plagiarized. If this were an undergrad course assignment, I'd give it an F; since the authors appear to be grad students, and since it appears to have been published in something pretending to be a scientific journal...
