Chris Shannon, the Richard Merkin Professor of Economics and Mathematics, is one of Caltech's newest faculty members. Her research involves developing mathematical models to understand financial markets and other mechanisms that allocate goods, such as auctions.
Rustem Ismagilov, the new John W. and Herberta M. Miles Professor of Chemistry and Chemical Engineering at Caltech, believes in the ability of science and technology to address significant societal problems—from the spread of HIV and drug resistance to bacterial imbalances in the gut.
André Hoelz, Caltech's newest assistant professor of chemistry, endeavors to fully characterize the nuclear pore complex, a cellular component made up of many copies of about 30 different proteins—perhaps 1,000 proteins in all and 10 million atoms—which forms a transport channel in the membrane of the nuclear envelope. Hoelz calls the complex "the gatekeeper of the nucleus."
Katrina Ligett, a new assistant professor of computer science and economics, is fascinated by problems that involve a conflict or tension between individual incentives and more global objectives. She uses ideas from computer science and mathematics to approach problems of algorithmic game theory.
Two new faculty members have joined the Division of Physics, Mathematics and Astronomy. Ryan Patterson, assistant professor of physics, studies the elusive neutrino, a mysterious particle that could hold the clues to some of the universe's biggest questions. Vladimir Markovic, professor of mathematics, is trying to understand the shapes and structures of mathematical spaces called manifolds. In particular, he's worked with a mathematical object that resembles a pair of pants.
The latest faculty to join the ranks as assistant professors in the Division of Geological and Planetary Sciences spend a lot of time gazing toward the heavens. Bethany Ehlmann has been working on understanding environmental conditions early in Mars's history, while Heather Knutson focuses on characterizing the properties of the planets that orbit stars other than our sun.
