Faculty & Student Spotlights

Spotlight: Maurice Wilson

Maurice Wilson

Maurice Wilson is a 1st year graduate student working with Prof John Johnson and Dr. Jason Eastman on characterizing Earth-like exoplanets around our nearest stars.  Maurice began collaborating with Prof Johnson and Dr. Eastman in 2015 as an undergraduate summer intern of the newly founded Banneker Institute at the Harvard-Smithsonian Center for Astrophysics.  He proudly credits the Banneker Institute for preparing him—as a senior undergraduate—for graduate school academically through the daily classes, professionally through the exoplanet research experience and emotionally through the social justice curriculum.  By the end of the internship, he was deeply immersed into the exoplanet research that he continues to work on now.  By observing the brightest stars in the night sky with the MINiature Exoplanet Radial Velocity Array (MINERVA), Maurice obtains photometry and radial velocities both with the high precision necessary to characterize rocky exoplanets with radii similar to the Earth’s radius.  

During his summer and winter breaks, Maurice presents his research and teaches youth about astronomy at the Adler Planetarium in his hometown of Chicago.  He also teaches a variety of scientific concepts via his blog, which is geared towards lay(wo)men outside of the scientific community.  Aside from blogging, Maurice likes to dance Salsa and Bachata in his spare time.

Spotlight: Marion Dierickx

Marion Dierickx

Marion Dierickx is a 4th-year graduate student working with Prof Avi Loeb on galaxies in the Local Group. With approximately fifty members, the Local Group is our cosmic backyard. In the same way that detailed studies in the Solar neighborhood have informed our understanding of stellar populations, the Local Group is the closest laboratory to study galactic evolution. Marion works on modeling the infall of dwarf galaxies into their larger neighbors, the Milky Way and Andromeda. Leveraging the capabilities of N-Body simulations, she hopes to learn about the evolving structures and morphologies of Local Group dwarfs. Marion serves as a student representative to the Astronomy Department’s Committee on Academic Studies. In her spare time, she enjoys hiking adventures, traveling and horse riding.

Elisabeth Newton is pursuing her PhD with Prof. Dave Charbonneau as a member of the MEarth Project. MEarth is robotic survey looking for transiting planets around red dwarf stars in the solar neighborhood, with sites in the northern and southern hemispheres. Elisabeth, along with fellow graduate student Jason Dittmann, leverages MEarth's extensive data set to study the properties of these small, nearby stars. Elisabeth is currently investigating the stars' rotation periods, which are essential to understanding their magnetic fields and angular momentum evolution. In her previous work, she obtained near-infrared spectra of nearly 500 of the MEarth targets and developed techniques to measure the stars' absolute radial velocities and to estimate their metallicities, temperatures, and radii. 

Elisabeth helped found the daily astronomy blog Astrobites and the ComSciCon workshop series on science communication. She recently talked at the CfA's public Observatory Night and tweets about science at @EllieInSpace. Elisabeth also enjoys art and baking, and can often be found rock climbing or biking around Cambridge.

Spotlight: Nathan Sanders

Nathan Sanders imageNathan Sanders received his Ph.D. from the Department of Astronomy in May, 2014, from the research group of Prof. Alicia Soderberg.  Since then, Nathan has served as Director of Quantitative Analytics at Legendary Entertainment's new Applied Analytics division in Boston, MA.  Legendary is a leading media company with film, television, digital, and comics divisions delivering content like The Dark Night and Godzilla to mainstream audiences, with a targeted focus on the powerful fandom demographic. At Legendary, Nathan applies the experience in scientific data analysis, Bayesian statistics, and machine learning that he developed during his thesis work at Harvard.  Using these techniques, Nathan and his colleagues at Legendary leverage emerging datasets to quantitatively model and predict consumer purchasing decisions in the entertainment industry, projecting market outcomes and optimizing targeted marketing campaigns at the individual consumer level.

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.
