John Sylak Glassman


John is a linguist and natural language processing engineer on the cartography team who works to improve Mapbox’s multilingual data-processing capabilities.

Before joining Mapbox, John was a postdoctoral fellow at the Center for Language and Speech Processing at Johns Hopkins University where he conducted research in automatically breaking down complex words in foreign languages. He earned a PhD in linguistics from the University of California, Berkeley, where he investigated the sounds of the world’s languages. His research focused on consonants produced in the back of the vocal tract, and involved doing field research on Vancouver Island and in the Peruvian Amazon. His research interests also include languages of the Caucasus, which he explored while majoring in linguistics and minoring in Russian at the University of Chicago.

In his spare time, John spends time with family near and far, explores cities, goes hiking, and reviews linguistics and NLP articles.
