Faculty & Student Spotlights

Spotlight: Charlie Conroy

In July 2014, the Harvard welcomed Charlie Conroy, new assistant professor of Astronomy, from UC Santa Cruz.  He brings with him two graduate students, Meng Gu and Jieun Choi. His research interests span a broad range of topics including stellar evolution and spectroscopy, the formation and evolution of galaxies, and the large scale structure of galaxies and dark matter.  His group is developing innovative techniques for probing the stellar populations within galaxies, including new observational strategies and theoretical tools. In 2013 he was awarded a Sloan Foundation Research Fellowship and a David & Lucile Packard Fellowship. Before arriving at Harvard, Charlie spent two years as an assistant professor at UC Santa Cruz. Charlie spends his spare time tending to a small organic farm with his spouse and two children.

Spotlight: John Asher Johnson

After spending four years as an assistant professor of Planetary Astronomy at Caltech, John Johnson is now a Professor of Astronomy at the Harvard-Smithsonian Center for Astrophysics. In 2012, he was awarded the Sloan Foundation Research Fellowship, the David & Lucile Packard Fellowship, the Feynman Teaching Prize, and the AAS Newton Lacy Pierce Prize for "for major contributions to understanding fundamental relationships between extrasolar planets and their parent stars." In 2013, he was named one of Astronomy Magazine’s “Ten Rising Stars” in astrophysics.

His primary research focus is on the detection and characterization of planets outside our Solar System, commonly known as exoplanets. His most recent work is focused on studying the properties of Earth-like planets around the Galaxy’s least massive stars, commonly known as red dwarfs. His group's notable discoveries include three of the smallest planets discovered to date, each smaller than the Earth and one the size of Mars. His group's statistical analysis of planets discovered around red dwarfs has revealed that there exist 1-3 Earth-like planets per star throughout the Galaxy. In addition to papers in professional journals and conferences, his work has been featured in the magazines Sky & Telescope, Astronomy, Discover and New Scientist. He blogs regularly at this URL and you can follow him on Twitter as @astrojohnjohn.

Spotlight: Matt Holman

Matt Holman

Matt Holman is a Smithsonian astrophysicist and lecturer with the Department of Astronomy and was featured in a recent Gazette series on Harvard’s engagement in Latin America, in this case through telescopes such as Las Campanas and Magellan. His work focuses on long-term dynamics of the Sun’s solar system and extrasolar planetary systems.  In 2003, his team of astronomers at the CfA and JJ Kavelaars of Canada discovered three previously unknown moons of Neptune, the first discovered from a ground-based telescope since 1949.  Sometime in 2015 Matt’s team will utilize NASA’s New Horizons spacecraft to explore objects in the Kuiper Belt, leftovers from the creation of the solar system 4.5 billion years ago.

Spotlight: Li Zeng

Li Zeng is a graduate student currently in his fifth year and hails from Chongqing, China.  Li is very passionate about holistic health and traditional healing.  He is a practitioner of Tai Chi and specialized forms of martial arts.  In conjunction with faculty member, Dimitar Sasselov, Li has created a new interactive tool to characterize and illustrate the interior structure of exoplanets. This tool, distributed at no cost to the public, is useful for observers to quickly constrain the interior structure of an exoplanet, for modelers to use in their computer simulations, and for instructors to illustrate the diversity of planetary structures in the classroom.

Spotlight: Edo Berger

Edo Berger is the John L. Loeb Associate Professor of the Natural Sciences and, as of July, Acting Director of Undergraduate Studies for the department.  He is pictured above with graduate student Wen-fai Fong in front of a model of colliding neutron stars that they assert are responsible for the creation of such heavy metals as gold in the universe.  His research group (view students and postdocs) is focused on the study of gamma-ray bursts, optical transients (mainly from the Pan-STARRS project), and magnetic fields in low-mass stars and brown dwarfs, using observations across the electromagnetic spectrum, from radio to γ-rays. Prof Berger was recently selected as the recipient of the 2013 Fannie Cox Prize for Excellence in Science Teaching awarded annually by Harvard's Faculty of Arts & Sciences.

Spotlight: Karin Öberg

The Department of Astronomy welcomed Karin Öberg as its newest assistant professor in July of this year. She is pictured here at her Leiden University dissertation defense  in 2009. Karin moved to Harvard from the University of Virginia where she held a joint faculty appointment in Chemistry and Astronomy. She previously held a Hubble Fellowship at the CfA.  Karin’s expertise is in astronomical and laboratory infrared spectroscopy of ices, laboratory investigations on ices dynamics and chemistry, single-dish and interferometric millimeter observations of molecular emission, and theory on how protostellar and protoplanetary disk chemistry affects planet formation. She is a Swedish native.

Spotlight: Yuan Sen Ting

Yuan Sen TingYuan-Sen is a graduate student working with Dr Alexey Vikhlinin and Prof. Christopher Stubbs. He is analyzing data from the NASA Chandra X-ray observatory to understand how often galaxy clusters merge. He is also very interested in galactic dynamics,  and plans to dissect the formation of the Milky Way via the motions and elemental abundances of stars in the Milky Way. He loves public outreach activities and has developed new educational tools for teaching.  Yuan-Sen is pictured here presenting at the Boston Museum of Science.
