Brief Bio

Hello! My name is Natasha Latouf, I am an NSF Graduate Research Fellow, and I attend George Mason University for graduate school. I am a contractor here at NASA GSFC while I finish my doctoral degree, researching exoplanet atmospheres. In my spare time, I enjoy tossing a ball with my corgi, Olive, and reading - I am currently making my way through the Game of Thrones books!

Research Interests

Exoplanet Atmospheres

Solar System: Atmospheres

I currently study the simulation of exoplanet atmospheres, and how to model them to reflect the data we have from Hubble and are projected to receive from the James Webb Space Telescope. I spend most of my time using the Planetary Spectrum Generator (PSG) to implement these simulations, and will also be embarking on benchmarking the noise and coronagraphy modeling within PSG.

Telluric Mitigation Methods

Solar System: Extrasolar Planets

For the duration of my undergrad, my research focussed on how our atmosphere (i.e. tellurics) induces error on ground-based observations of precise radial velocities (PRVs). I also studied how effective the most common telluric mitigation methods are in reducing or eliminating these errors, particularly the Cross-Correlation Function (CCF) and forward modeling. This work was initiated as a part of the NASA probe mission concept study EarthFinder with a solar star model initially, and I have continued this work to study an M2 dwarf model.


Research Assistant

George Mason University - Fairfax, VA

October 2017 - May 2021

I wrote and implemented python scripts to quantify the amount of error induced on radial velocity measurements due to Earth's telluric interference. I also aided in observations using the George Mason University telescope, the Keck telescopes, and NASA's infrared telescope using iShell.

NSF Graduate Research Fellow

George Mason University - Fairfax, VA

September 2021 - Present

I currently focus on simulating exoplanet atmosphere models using the Planetary Spectrum Generator (PSG). I will also be working on benchmarking the noise and coronagraph models within PSG for varying telescopes and instrument, including the next generation of Great Observatories.

Teaching Experience

I was a tutor for student athletes within George Mason University for two years, teaching various mathematics and physics courses as requested. I also ran my own private tutoring business offering tutorship in mathematics and physics. These courses included: Pre-Algebra, Algebra 1 & 2, Pre-Calculus, Calculus 1, 2, & 3, Discrete Mathematics, and Physics 1 & 2 (both calculus and non-calculus based).


I attended George Mason University for both my undergraduate and graduate studies. I graduated with honors in 2021 from George Mason with my Bachelors of Science in Physics, with a concentration in Astrophysics. I am currently in attendance for my doctorate degree, which will be in Physics with a concentration in Astrophysics as well.

Other Professional Information

I am a co-Founder and current leader of the student organization Spectrum at George Mason University. This is a group dedicated to the enhancement of underrepresented groups in STEM based on the co-founders personal experiences. We feature a mentorship program for every career stage, a Professional Development Lunch Talk Series, a Faculty Mentoring Committee, and we wrote the Code for Professional Ethics currently in place within the Physics and Astronomy Department. If you are interested in this program, please feel free to reach out to me!
