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 Comparing standard deviations of two unknown lists
No, the standard deviation is not in any way linked to the average. In fact, the standard deviation is basically defined to be independent of the average -- the usual way of calculating it involves first normalizing the data by subtracting the average from all data points.

comment How to find fast modular exponentiation?
Just about the fastest way I know to calculate $5448^{5^3} \pmod{11251}$ is to type pow(5448, 5**3, 11251) into the Python shell. But I assume you're after something else?

comment $3$ dimensional light up cube ornament, # of rows/cols/diags in/on a cube
There are 4 "full" diagonals that cross from one corner of the cube to the opposite one, not 3. If you also consider "semi-diagonals", where one of the three coordinates is constant, there are $3\cdot2\cdot4=24$ of those.
