Dr. Diana Dragomir's Research Group

Postdoctoral Scholars

David Coria

David is a queer Latino astronomer, stellar spectroscopist, and exoplaneteer. During his PhD at the University of Kansas, David investigated how dwarf star elemental and isotopic abundances can test galactic chemical evolution models and how they correlate to other stellar properties. David also measures volatile abundances (C, N, O) in exoplanet host stars to predict the formation history of their companion exoplanets targeted by JWST and state-of-art ground-based observatories. Outside of research, David enjoys music and currently performs with the Albuquerque Civic Chorus and Encantada: The Band of Enchantment.

Dominic Oddo

Website: https://doddo15.github.io/

Dom (he/him) is a sixth year PhD student with a primary research focus in transiting circumbinary planets (CBPs) and a NASA FINESST Future Investigator. CBPs are exoplanets orbiting tight binary stellar systems, and they are an exciting lens to study the formation of both tight binary systems and exoplanets. His PhD dissertation project is to find an occurrence rate for this population of planets with the TESS mission.

Graduate Students

Brett Skinner

Brett is a fourth year graduate student who’s interested in the observation and characterization of long period transiting exoplanets as they are an important next step in the study of the demographics of exoplanets. He is currently working on adding to the growing list of these long period exoplanets in hopes that they can be readily observed and studied by professional and amateur astronomers alike. Outside of research, Brett enjoys swimming and skiing and aspires to be an amateur chess player.

Sarah Stamer

Website: https://sstamer23.github.io/

Sarah is a third year graduate student (and was previously a REU intern in our group!). Her pre-candidacy project consists of analyzing JWST NIRSpec transmission spectra data of the Hot Neptune LTT 9779b to learn more about the atmosphere of this "Hot Neptune Desert" dweller. Stay tuned for updates as she works towards a first-author paper in a year or so! Outside of classes and research, Sarah enjoys reading, watching sports, crocheting, and plays percussion in the Albuquerque Concert Band.
