Caltech's newest astronomy professor searches for cosmic radio waves
News Writer:

Growing up in rural northwest Ireland, beyond the reach of city lights, Gregg Hallinan fell in love with the night sky. "When you didn't have bad weather, and you didn't have clouds, the skies were nothing short of spectacular," he says. "From a young age, I was obsessed with astronomy—it's all I cared for. My parents got me a telescope when I was seven or eight, and from then on, that was it." Now, Hallinan has brought his celestial obsession to Caltech as a new assistant professor of astronomy.

Gregory C. Fu, a new faculty member and the Altair Professor of Chemistry at Caltech, uses his intuition and creativity to develop new chemical reactions that make chemical conversions more efficient—enabling organic chemists to convert reactants into their desired products in fewer steps or with higher yields than previously possible, for example. He talks about the creative aspects of organic chemistry, some of his current work, and making the move to Caltech.

David Hsieh, an assistant professor of physics, is one of Caltech's newest faculty members. Hsieh grew up in Hong Kong before hopping the Pacific to earn his BS in physics and mathematics in 2003 from Stanford. Hsieh then received his PhD from Princeton in 2009 and was a Pappalardo Fellow at MIT before joining Caltech's faculty on September 1. He recently answered a few questions about his work—and some culinary experiments.

Andrew Ingersoll, Earle C. Anthony Professor of Planetary Sciences, has been a leader in the investigation of planetary weather and climate for nearly five decades. His research has included studies of the so-called runaway greenhouse effect that is thought to have boiled away Venus’s oceans, the presence of liquid water on Mars, the supersonic winds on Jupiter's moon Io, and the atmospheric dynamics of Jupiter, Saturn, Uranus, and Neptune.


Literature in the Middle Ages: An Interview with Jennifer Jahner

This fall, Jennifer Jahner joined Caltech as an assistant professor of English. As an undergraduate, she planned to study environmental science at Western Washington University. But as a lifelong reader, she couldn't elude the lure of literature, and she ended up majoring in English instead, receiving her BA in 1998. Afterward, she spent several years as a book editor before returning to academia as a graduate student at the University of Colorado, Boulder, where she took a seminar on medieval literature—a class that she says changed her life. Discovering a passion for the time period and for studying old, rare manuscripts, she got her MA in 2005 and then went to the University of Pennsylvania, where she received her PhD last spring. Jahner recently answered a few questions about her research and her thoughts on joining Caltech.

This fall, Andrei Faraon (BS '04) returned to his alma mater to take a position as an assistant professor of applied physics and materials science. In his work, he builds devices that attempt to use light to manipulate single quantum systems in solids. Faraon recently answered some questions about his research and returning to Caltech.

The Miracle and Beauty of Physics: An Interview with Cliff Cheung

When you lift a paper clip off a table with a small magnet, you're accomplishing a remarkable feat: the tiny magnet is overcoming the gravitational pull from the entire Earth. Why does gravity seem so weak compared to electromagnetism and the other fundamental forces of nature? This vast discrepancy in scale—how a small magnet can beat out a whole planet—is related to what physicists call the hierarchy problem. Cliff Cheung—who joined Caltech this fall as an assistant professor of theoretical physics—is fascinated by this "very deep puzzle" (which may be solved through supersymmetry, a class of theories in which every fundamental particle has a partner particle, as well as by dark matter, the mysterious stuff that accounts for nearly a quarter of the universe). Recently, Cheung—who also plays guitar and piano, sings, and writes music—answered a few questions about coming to Caltech and his passion for physics.

Quantum computers—computers that harness the bizarre laws of quantum mechanics to become vastly more powerful than conventional computers—have been touted as the next leap in technology. Although useful quantum-computing technology is probably years—and possibly decades—away, physicists like Jason Alicea, who joined Caltech's faculty this fall as an associate professor of theoretical physics, are working hard to make it a reality. Alicea's research involves translating purely theoretical ideas into real-life experiments and applications. He recently answered a few questions about himself and his research.

Almost immediately after the Big Bang—roughly after ten trillionths of a trillionth of a trillionth of a second—the universe suddenly grew. Very fast. The entire cosmos, which at the time was smaller than an atom, expanded to the size of a beach ball in less than a millionth of a trillionth of a trillionth of a second—before settling down to a more leisurely rate of growth that continues to this day.

Cause and Effect: An Interview with Frederick Eberhardt

Determining cause and effect is complex and fraught with difficulty, from our intuitive—but often mistaken—sense of the causes of events in our daily lives to the perils of structuring and interpreting scientific experimentation. One problem with teasing apart these relationships is that there are many cause-and-effect sequences that we can only observe; we cannot meaningfully intervene, which may make it more problematic to test causal relations.
