Current NASA-PEER Post-bacs

Yesenia Arroyo
Yesenia Arroyo is affiliated with the Exoplanets and Stellar Astrophysics Laboratory as a communications specialist in the NASA Goddard Astrophysics communications team, curating engaging web content for NASA Universe and supporting outreach efforts for the Habitable Worlds Observatory. Yesenia is also a research assistant in the Planetary Geology, Geophysics, and Geochemistry Laboratory, investigating and mapping lunar volcanic morphology in Sinus Vicositatis.

Emmie Aufderheide is affiliated with the Planetary Systems Laboratory at NASA Goddard Space Flight Center. Emmie works with Conor Nixon to study the photochemistry of Titan’s atmosphere. Their goal is to create a refined list of the most critical reaction rates and branching ratios using a Titan photochemical model.
Dex Bhadra is affiliated with the Exoplanets and Stellar Astrophysics Laboratory at NASA Goddard Space Flight Center. Dex is working with Dr. Sean Terry on designing a microlensing survey for the Roman Space Telescope. He is creating an automated image-constrained microlensing pipeline that can use future Roman image observations to break microlensing degeneracies.

Matthew Buchan is affiliated with the Observational Cosmology Laboratory at NASA Goddard Space Flight Center. Matthew is working with Dr. Al Kogut on the PRIMA far-infrared probe Phase A study. His research focuses on the optical performance and optomechanical design of the FIRESS Fourier transform module.

Ethan Harvey
Ethan Harvey is affiliated with the X-ray Astrophysics Laboratory at NASA Goddard Space Flight Center. Ethan is working with Dr. Antara Basu-Zych on forming a large catalog of extremely metal-poor galaxies. His research focuses on collating the X-ray detection data of said galaxies to lower the knowledge constraints of high energy emissions during early cosmic epochs such as reionization.

Sangeeta Kumar
Sangeeta Kumar is affiliated with the Observational Cosmology Laboratory at NASA Goddard Space Flight Center under the mentorship of Drs. Sangeeta Malhotra and James Rhoads. Sangeeta is working on simulating Lyman Alpha galaxy spectra using the Nancy Grace Roman Space Telescope in order to understand the Cosmic Dawn. This work is pertinent to understanding what Roman can see and what astronomers can expect from the soon to be launched telescope.

Kyla Mullaney
Kyla Mullaney is affiliated with the X-ray Astrophysics Laboratory at NASA Goddard Space Flight Centerworking with Dr. Kim Weaver and Dr. Kelly Whalen. She researches the kinematic impacts of Active Galactic Nuclei and star formation on galaxy evolution, using spatially-resolved IFU spectroscopy and X-ray observations.

Matias Calderon is affiliated with the Observational Cosmology Laboratory at NASA Goddard Space Flight Center. Matias is working as a research assistant under Dr. Karwan Rostem to develop a virtual image phase array (VIPA) spectrometer instrument for the far-infrared range. Matias supports Dr. Rostem’s work through computer aided design (CAD) to design instrument components and by developing instrument and test software.

Rachel Hemmer
Rachel Hemmer is affiliated with the X-ray Astrophysics Laboratory at NASA Goddard Space Flight Center. Rachel performed theoretical and computational work in support of the upcoming X-ray Imaging and Spectroscopy Mission (XRISM). She is now studying metallicity evolution of galaxy clusters.

Fiona McDaniel
Fiona McDaniel is affiliated with the Observational Cosmology Laboratory at NASA Goddard Space Flight Center. Fiona McDaniel is affiliated with the Observational Cosmology Laboratory at NASA Goddard Space Flight Center. Under Dr. Alexander Kutyrev, Fiona uses deep learning techniques to identify gamma ray bursts in PRIME telescope photometry data.

Paul Wampler
Paul Wampler is affiliated with the X-ray Astrophysics Laboratory at NASA Goddard Space Flight Center. Paul is working with Dr. Francesca Civano to study the variable emission of obscured Active Galactic Nuclei (AGN) and constrain their geometry. To this end, he is reducing hard X-ray NuSTAR data and performing spectral analysis using obscured AGN models such as MyTorus.

Matraca Elling is affiliated with the Planetary Environments Laboratory at NASA Goddard Space Flight Center. Matraca is working with Dr. Jennifer Stern to obtain carbon isotope data from low molecular weight species that evolve during thermal decomposition experiments on planetary materials, utilizing a pyroprobe coupled to a gas chromatograph and an Isotope-Ratio Mass Spectrometer (pyro-GC-IRMS).

Megan Hur
Megan Hur is affiliated with the Earth Science Division at NASA Goddard Space Flight Center.

Julie Moquin
Julie Moquin is affiliated with the Exoplanets and Stellar Astrophysics Laboratory at NASA Goddard Space Flight Center, working with Dr. Robby Wilson and Dr. Elisa Quintana. Julie is contributing to the development of an automated pipeline to detect and vet exoplanet transits in Kepler Bonus light curves, tripling the number of stars in the Kepler sample that can be searched for new planets. Her work will enable more precise and complete occurrence rate estimates for small planets, with direct implications in planet demographics and the development of future missions.

Chana Werblowsky
Chana Werblowsky is affiliated with the Gravitational Astrophysics Laboratory at NASA Goddard Space Flight Center. Chana is working with Dr. Jeremy Schnittman to incorporate the power of multiple existing simulation codes into a single integrated package to make detailed predictions of the X-ray spectra, timing properties, and polarization signatures from accreting black holes in a variety of states.
