- I grew up in the San Francisco Bay Area, where I spent my free time skateboarding and thinking about uncountable infinities. These interests led me to study mathematics at Harvard University, where I was an undergraduate. When I realized that artificial intelligence can provide tools to solve a variety of problems, I joined the Harvard Intelligent Probabilistic Systems group. I am broadly interested in applied math, machine learning, and optimization, and I am currently a member of the Statistical AI Lab and the AMPLab at UC Berkeley.

- The Rainbow Game is played by a team of seven. Each player gets a hat, which can be any one of the seven colors red, orange, yellow, green, blue, indigo, and violet. The colors of the hats are independent of each other and repetitions are allowed: for instance, it may happen that all the hats are green. Each player can see only the colors of the six hats worn by the rest of the team; no player can see the color of his or her own hat. The players are to guess the colors of their own hats, and if at least one player guesses correctly then the team as a whole wins. The players may not communicate in any way during the game, and they must all announce their guesses simultaneously. They are, however, allowed to plan out a strategy in advance, and they hope to find a strategy which will guarantee them success for every possible arrangement of hats. Is there such a strategy? Either find one or show that it cannot exist. (As a warm-up, try two players and two colors, or three players and three colors.) Taken from the 2006 Mathcamp Qualifying Quiz.
