In 2024 I received my Ph.D. in Applied Mathematics/Mathematical Engineering from TuDelft in Delft, the Netherlands, and Universidad EAFIT, Medellin, Colombia, with a thesis entitled Data assimilation in a LOTOS-EUROS chemical transport model for Colombia using satellite measurements.

During my Ph.D., I worked as a postdoc in the TuDelft-KNMI-VU PIPP project “High Resolution to Exploit Nitrogen Chemical Compound Observations from Space in the Netherlands” (2021—2024).

From 2015-2016 I did a MSc in Applied Physics at Universidad EAFIT, Medellin Colombia and from 2006–2014. I studied Physics at Universidad de Antioquia, Medellin Colombia (2006–2009) not finished and later studied Physical Engineering at Universidad EAFIT, Medellin Colombia (2010–2014).

I was born on 24-12-1987 in Medellin, Colombia. Due to my father’s work, my family lived in Bogotá from 1994 to 2005 and I went to primary school at Colegio Italiano Leonardo Da Vinci, Bogotá Colombia (1994–2000) and at Colegio Padre Manyanet, Medellin Colombia (2001–2005) when my family moved back again to Medellin.

Research interests

My work uses Data Assimilation (DA) techniques to integrate large-scale numerical models, satellite information, and data from different sources. DA techniques play a fundamental role in improving the system states that represent meteorological or chemical atmospheric conditions. This allows us to incorporate different real observations into the models, taking advantage of these two sources of information: observations and mathematical models.

I am passionate about satellite intruments and their use for different applications, specially the ones related to atmospheric composition. Different satellites have been carrying sensors to monitor atmospheric concentrations since 1964. From Paul J. Crutzen’s idea of having spectrometers onboard satellites, an open field in the study of atmospheric chemical composition was created. Chronologically appeared the Global Ozone Monitoring Experiment (GOME, (1996-2003), GOME2A (2007-), GOME2B (2013-)), the Scanning Imaging Absorption Spectrometer for Atmospheric Cartography (SCIAMACHY, 2002e2012), and the Ozone Monitoring Instrument (OMI). Each instrument generation has improved different data characteristics in the measured spectra, solving ratios and signal-to-noise problems and increasing spatial and temporal resolution. My recent study has been towards the use of TROPOMI NO₂ satellite concentrations, assimilating those in the Chemical Transport Models LOTOS-EUROS using different meteorology inputs such as ECMWF, WRF or HARMONIE models.
