    Alexandra de Castro

    I am a science and technology communicator and a bilingual freelance writer —Spanish and English— with a research scientist background (Ph.D. in Physics). I hold a specialization in communication and divulgation of science and technology by the University of Oviedo, Spain (2014). My fifteen years of experience as a scientist include a postdoc position at the Institute for Theoretical Physics at the Leibniz University of Hannover, Germany (DAAD fellow); Professor of physics, tenured, at Universidad Simón Bolívar, Caracas, Venezuela; and Research Associate at the University of Sydney, Australia. For the last three years, I have been the Leader of the non-profit organization Persea Foundation. I joined United Academics magazine as Editor in 2021. My passions are theoretical physics, particle physics, climate change, astronomy, and space exploration. My Twitter is @Brownianaweb.
