The OBF Travel Fellowship program, established in 2016, aims to increase diverse participation at events related to open source bioinformatics. Applications are reviewed three times a year. Applicants may apply for attending any event that develops or promotes open source development and open science in the biological research community. It doesn't have to be an OBF-related event, and it can be one that you already attended in the recent past.
