Introducing Brian Jackson

Brian Jackson ( is an assistant professor teaching astronomy in the Physics Department at Boise State University. Before coming to Boise State, he was a postdoctoral fellow at the Carnegie Institution of Washington’s Dept. of Terrestrial Magnetism in Washington DC and before that, at NASA’s Goddard Space Flight Center in Greenbelt MD. He earned a PhD in Planetary Sciences from the University of Arizona‘s Lunar and Planetary Laboratory in Tucson AZ and my BS in Physics from Georgia Tech in Atlanta GA. His research focuses primarily on orbital dynamics and transit observations of extrasolar planets, planets outside of our solar system. He also does some planetary science field work, notably on Death Valley’s Racetrack Playa ( and on terrestrial and Martian dust devils.


Introducing Laura Mayorga

Dr. Laura Mayorga (@mayorgalc) is a Harvard Future Faculty Leaders Fellow based at the Harvard-Smithsonian Center for Astrophysics. She is interested in exploring the diversity in exoplanet atmospheres by using Solar System objects as analogs for their exoplanet counterparts. From flyby data of Jupiter taken by the Cassini Spacecraft she is laying the groundwork comparison dataset needed to understand the underlying, unresolved phenomena in the atmospheres and on the surfaces of planets around other stars.
A lover of accents and languages if she can’t be Cdr. Spock she would be Lt. Uhura. When not engaged in science research and communication, she enjoys cycling to the closest beach, crocheting the next unfinished project, or playing video games at home where her first duty is to be a warm lap to a caliby named Stellar. She finds the rules for what makes something a cookie vs. a biscuit fascinating and she plays the ocarina while traveling, where the cat won’t try to stop her.

Introducing David Wilson

David Wilson (@astrodave2) is a postdoc at the University of Texas at Austin, having recently moved there after completing his PhD at the University of Warwick. His research focuses on observing M dwarf and white dwarf stars using Hubble and other space telescopes. He uses those observations to explore the effects of stellar activity on extrasolar planets and to study the remnants of planetary systems around dead stars. In particular, David is a member of the Mega-Muscles collaboration, which is using a large number of telescopes to produce an archive of pan-chromatic M dwarf spectra.

Along with his research, David is also interested in science communication and outreach. During his PhD he was a writer for the Astrobites collaboration and regularly visited local schools to give talks and present planetarium shows. When not working, David can usually be found reading sci-fi books or adding to his space-themed Lego collection.

Introducing Jessie Christiansen

Dr. Jessie Christiansen (@aussiastronomer) is a research scientist at the NASA Exoplanet Science Institute at Caltech. She searches for, studies, and catalogues extrasolar planets — planets orbiting other stars. Her main research focuses on using the thousands of exoplanets found by the NASA Kepler and K2 missions to determine how common planets similar to the Earth might be throughout the Galaxy, and she is getting ready to do the same with the NASA TESS mission.

She is an avid science communicator, and is particularly engaged with reaching and elevating under-represented minorities in the sciences. When she is more engaged with this particular planet, she is chasing her twin 3-year-olds around, enjoying various sci-fi/fantasy fandoms, and is married to fellow astronomer @PFHopkins_Astro.

Introducing Adina Feinstein

Hi! My name is Adina Feinstein, and I just finished my undergraduate degree in astrophysics at Tufts University and will continue my education next year at U of Chicago. My research experiences range from galaxy evolution to correcting for gravitational lensing to aging stars and characterizing exoplanets. I hope to use my time on Astrotweeps to talk about my research, the graduate school application process, and offer advice to those who wish to pursue astronomy in the future. Outside of academia, I’m a bake-aholic, love to crochet, and enjoy writing the occasional short story!


Introducing Ben Montnet

Ben Montet (@benmontet) is a NASA Sagan Fellow at the University of Chicago. He works to find and characterize planets with Kepler and K2, and soon, the upcoming TESS mission. He also uses Kepler data to better understand stellar activity through observations of long-term brightness variations of stars. (Ask him about KIC 8462852, or “Boyajian’s Star.”)
Ben is originally from the Chicagoland area, receiving his BS from the University of Illinois before heading to sunny California for his PhD at Caltech. When he’s not in the office, he enjoys traveling, watching the Cubs, and exploring his old and new hometown of Chicago.

Reintroducing Jonathan Fortney

Jonathan Fortney is a Professor in the Department of Astronomy and Astrophysics, University of California, Santa Cruz, and the director of their Other Worlds Laboratory ( He received his PhD in Planetary Sciences in 2004 from the University of Arizona and was a postdoc for 4 years at NASA Ames Research Center before starting at UC Santa Cruz in 2008.

Jonathan’s major fields of interest are the atmospheres, interiors, spectra, composition, and evolution of planets, both inside and outside the solar system.  He focuses on modeling and theory of these objects, with targets that range from terrestrial planets to brown dwarfs.  He was a member of the Kepler Science Team during its prime mission and is currently a member of the Cassini Science Team.
