I am currently an Assistant Professor at Universidad de Santiago in Chile. Previously I was a NASA NPP fellow at NASA (AMES).
My research focuses on AGN feedback, galaxy clusters, and the origin of multiphase gas using ALMA, MUSE, Chandra, and JWST observations.

Using a sample of seven X-ray bright cooling-flow clusters, we discovered a tight correlation between the X-ray and Hα surface brightness of multiphase filaments spanning more than two orders of magnitude. By isolating the filamentary X-ray emission from the surrounding intracluster medium, we reveal a direct connection between the hot and warm gas phases.
I investigate the chemical connection between warm ionized and X-ray-emitting gas in massive elliptical galaxies. Using MUSE and Chandra observations, I study how AGN feedback regulates metal transport, gas cooling, and the formation of multiphase structures across different temperature phases.

I study the effect of the intracluster medium (ICM) "weather" on AGN feedback and explore whether it is necessary for the formation of multiphase filaments in nearby Planck-selected galaxy clusters using Chandra and MUSE observations.

I study the evolution of AGN feedback in brightest cluster galaxies. Using a nearly unbiased sample of Planck-selected clusters observed with Chandra, I investigate the prevalence of X-ray cavities across cosmic time. Our results suggest that AGN feedback has remained largely unchanged over the past ~8 billion years

I study the origin of multiphase filaments in cool-core clusters. Using ALMA, MUSE, and Chandra observations, I investigate whether these structures form through AGN-driven turbulence or gas uplift behind buoyantly rising radio bubbles.

I investigate the origin of cold molecular and warm ionized gas in nearby galaxy groups using MUSE and Chandra observations. These environments provide a unique laboratory where galaxy interactions and mergers are more common than in massive clusters.

I studied the origin of extreme star formation in high-redshift submillimeter galaxies using SINFONI/VLT observations. Our results suggest that these intense starbursts are primarily triggered by galaxy interactions and major mergers.
