A Little About Me

My Current Position at ESO

I currently hold a Faculty position at the European Southern Observatory (ESO), Garching. My role as an Astronomical Data Scientist at ESO is within the Directorate of Operations (DoO), Data Management and Operations Division (DMO), Back-End Operations Department, in the Science Archive Group. In short, this means my day-to-day work involves various aspects of the ESO Science Archive.

My Science

My research interests include the processes controlling high-mass star and stellar cluster formation within (infrared dark) molecular clouds across various environments — from the disk and the Galactic Centre of the Milky Way to (giant) molecular clouds in nearby extragalactic systems — and how these can be constrained using observational tools, such as molecular line emission. Recently, I have begun exploring an exciting new avenue of research, applying my expertise to studying the effects of stellar feedback on its surroundings as a function of environmental properties.

Observations

I primarily work with observations from a variety of telescopes (both interferometric and single-dish) across a wide range of wavelengths, from millimetre and sub-millimetre radio to optical and infrared. These include, but are not limited to, ALMA, NOEMA, IRAM-30m, VLT/MUSE, HST, Spitzer, Herschel, and soon, JWST.

My Past Positions

I was recently a Fellow at ESO (until November 2024). Prior to that, I was a postdoctoral researcher (2018–November 2022) at the Argelander-Institut für Astronomie (AIfA) at the University of Bonn, working in the group of Frank Bigiel. I completed my PhD (2014–2018) at Liverpool John Moores University (LJMU) and the Max Planck Institute for Extraterrestrial Physics (MPE) under the supervision of Steven Longmore and Paola Caselli. My undergraduate studies (bachelor’s and master’s degrees) were completed at the University of Leeds (2010–2014).
