Juliana García-Mejía

Center for Astrophysics


Juliana García-Mejía is a fourth year graduate student at the CfA. Her research is focused in the development of novel astronomical instrumentation to enable the search for signs of life in other planets. She has spent her PhD leading the design and construction of The Tierras Observatory, a new 1.3m ultra-precise fully-automated photometric observatory located atop Mt. Hopkins, Arizona. By regularly achieving unbinned photometric precisions well below 700 ppm, Tierras will be able to detect Earth-like planet transits orbiting mid-to-late M dwarf stars, as well as enable the search for exo-rings and exo-moons. Juliana is invested in promoting equity and inclusion within Astronomy and STEM, with particular attention towards engaging young Colombian students with the millenary question of whether life exists elsewhere in the Universe. In her spare time, Juliana enjoys reading, cycling, training for triathlons, and dancing.
