The Open Bioinformatics Foundation has been accepted as a mentoring organisation for the 2018 instance of the Google Summer of Code. OBF is acting as an umbrella for ten bioinformatics Open Source projects, making it possible to offer a very diverse set of student projects.
Are you a student and interested in applying for any of the projects? The student application period is open from March 12th through 27th from the official GSoC website. See the full timeline for details. Feel free to contact the mentors of projects you are interested in already, though.
