The 2012 transit of Venus. I took this photo with a Newtonian Telescope (114mm x 900mm) using a Baader filter and an iPhone 4S. 
In addition to research, I am interested in outreach and astronomy education. In 2010 I started with Nelson Vargas an astronomy outreach group ( Astro-K ) at the Konrad Lorenz University, to spread interest and enthusiasm for astronomy to the general public. We have prepared festivals, public talks, radio programs and courses. During the summer of 2012 I did an internship with the European Union Universe Awareness ( EU-UNAWE) educational programme at the Department of Astronomy of Leiden University in the Netherlands, where I did research on Open Educational Repositories, public outreach initiatives and astronomy development evaluations under the supervision of Pedro Russo
Communicating Astronomy with the Public (CAP)
I was part of the Local Organizing Committee (LOC) of ​​​​​ Communicating Astronomy with the Public 2016 (CAP 2016) conference, organised by Commission C2 of the International Astronomical Union (IAU). It was the eighth in a series of conferences to promote the exchange of ideas and best practices in the field of astronomy and space communication, as well as informal education.
Bogotá's moon (Circa 2009) I took this photo with a Newtonian Telescope (114mm x 900mm) a Canon (I do not remember the details but it should have been something like ISO 100, Aperture f/11, Shutter Speed 1/125)
In 2016 I had the opportunity to be an Instructor at ​​​​​​​​ Clubes de Ciencia Colombia , a non-profit organization founded in 2014 that organizes hands-on week-long workshops in STEM to kids in developing countries at no cost. My club was cosmology-related and we worked on measuring the shape of the Universe with Planck´s data inspired by the amazing idea proposed by N. Cornish, D. Spergel and G. Starkman in Class.Quant.Grav. 15 (1998) 2657-2670. ​
Since 2017's summer Joe Bretz and I started to host ​​​​​​​ Astronomy on Tap events (AoT) in Bozeman (AoT-BZN) and with Miguel Ángel Rodriguez y Viviana Márquez in Bogotá (AoT-BOG). 

AoT consists of a series of short, free, public astronomy-related presentations in a bar. Each FREE event features accessible, engaging science presentations on topics ranging from planets to black holes to galaxies to the beginning of the Universe.
