I'm currently working as a post-doctoral researcher at the School of Earth and Space Exploration at Arizona State University. Here I carry out independent research on galaxies far away from our own Milky Way. My mentors are Sangeeta Malhotra and Rogier Windhorst. See the Contact tab for my contact info in case you have any questions. My main research project here at ASU is SÍGAME - a module designed to model nebular line emission in the far-infrared from galaxies and make predictions for future observations (click below to keep reading):
I also quantified the presence of AGN in massive galaxies at z~2 using CHANDRA archival data: Measuring the AGN fraction among star-forming and quiescent galaxies at z~2 (ApJ 764 4, 2013)

My research focuses on the Interstellar Medium (ISM) of galaxies, i.e. that gas out of which stars are formed. The amount and properties of the ISM play a crucial role for the evolution of a galaxy, yet for galaxies at high redshifts both are poorly determined by observations. By observing a portion of ISM in different wavelengths, different images emerge, and astronomers can extract important information from each:
The best technique for observing the ISM is to look for emission lines in the infrared (left bottom panel above), where rotational lines of molecules and fine structure lines of atoms and ions are easily excited at typical ISM temperatures and densities.
I make theoretical predictions for the observations of such lines by applying subgrid physics to galaxy simulations. The aim of this work is to bridge the gap between observations and models, in order to aid future interpretation of observations at high redshifts. For that purpose, I created a method called SÍGAME during my PhD which I am now developing further and translating to Python (from IDL). At some point I hope to make the code public on GitHub, so stay tuned! You can get a better introduction to my theoretical work by taking a look at the first chapter of my thesis, available here.
Approaching that bridge from the other end, I am also interested in observing normal star-forming galaxies at redshift z=2 and above. For that purpose, I am involved in the HELLO project (PI: S. Malhotra) and writing proposals for NOEMA, JVLA and ALMA.
Organizer of Python Programming meetings: I organize group meetings for scientists using python in their research at the School of Earth and Space Exploration, part of Arizona State University. The group meets up every second week and we have a github repository to share knowledge and ask questions. We decide a topic for each meeting based on what people are having most struggles! Typically, the meetings start with a short presentation by someone who has experience in the topic followed by discussion and hands-on learning. The group includes undergrads to professors, and is not restricted to SESE members, so if you would like to join the mailing list or be part of the github repository, just shoot me an email.

Co-organizer of P^3 = Postdoc Posters and Pie Research Forum at SESE in 2016 and 2017, ASU: I help organizing an annual poster conference at SESE, ASU, for postdocs and others to see some of the amazing science that goes on at SESE! Below is a photo taken from a balcony above the scene:
