Dr Alejandro Sanchez De Miguel
Postdoctoral Research Fellow


Alejandro has been involved in light pollution issues since the mid 1990s and has contributed to over 100 articles and contributions to conferences many related to light pollution. He is the leader of “Cities at Night,” a citizen-supported project coordinated with NASA and other space agencies that uses ISS night imagery to raise light pollution awareness.  He earned his PhD from the Universidad Complutense de Madrid (UCM), with a thesis titled, “Spatial, Temporal and Spectral Variation of Light Pollution and its Sources: Methodology and Results.”

Alejandro is currently doing his postdoc research fellow at Environmental and Sustainability Institute of the University of Exeter and serves as a light pollution advisor to the Instituto de Astrofísica de Andalucía (IAA) newly created Office of Night Sky Quality.  He is an active member of several astronomy and light pollution-related organizations and research networks in Europe, including Cel Fosc (Spain’s association against light pollution) and Sociedad Española de Astronomía (SEA), Loss of the Night network (LoNNe) and STARS4ALL.

In 2014, Alejandro received an IDA Dark Sky Defender award for his leadership role in “Cities at Night” project.
