Wanda Díaz-Merced is an astronomer best known for using sonification to turn large data sets into audible sound.[2][3][4][5] She currently works at the South African observatory’s Office of Astronomy for Development (OAD) leading the project AstroSense.[6]

Early Life[edit]

Dr. Díaz-Merced was born in Gurabo, a small remote town in Puerto Rico. Both Dr. Diaz-Merced and her sister had physical disabilities, and had to learn to overcome the challenges that brings. As children, the two of them would pretend to fly a space craft and explore other galaxies.[1]

In middle school she entered the school science fair where she won second place. This was a turning point for her as this made her realize that pursuing a career in science was something that might be attainable.[1][6]


Díaz-Merced attended Matías González García Middle School and Dra. Conchita Cuevas High School in Gurabo, Puerto Rico.[7] She then went on to study physics at the University of Puerto Rico.[8] She received a doctorate from the University of Glasgow in 2013, where she studied space data analysis.[9] She was then accepted as a post-doctoral fellow at the South African Astronomical Observatory in Cape Town.[4]

Scientific Career[edit]

She works at the South African observatory’s Office of Astronomy for Development (OAD). She has led the OAD project AstroSense since April 2014.[10][11] She worked on the technique after she lost her sight as an undergraduate at the University of Puerto Rico.[12][8] In 2016, she gave a TED Talk in Vancouver, BC, Canada.[13] She is a member of the International Astronomical Union.[14] While working at the Harvard-Smithsonian Center for Astrophysics, she collaborated with Gerhard Sonnert on a music album based on her audio representations.[2] Composed by Volkmar Studtrucker, "X-Ray Hydra" includes nine pieces of music derived from NASA's Chandra X-Ray Observatory rendered as sound.[15] [16]


In 2017 she was awarded an Estrella Luike trophy.[17]
