The Nature Masterclasses On-demand is now accessible via Sungkyunkwan University (SKKU) Library from June 1st, 2025 to February 28th, 2026. This platform, specifically tailored for researchers, offers professional training courses taught by journal editors of the Nature Portfolio and internationally acclaimed experts. From designing research and securing funding to writing and publishing a research paper, the courses are outlined to help researchers develop practical skills that are essential in the research field. Additionally, the courses are designed to be self-paced and compact, with modules consisting of multiple short lessons and even micro-learning courses that can be completed in 10 to 15 minutes. This is specifically helpful for researchers who are unable to finish a course in a given time due to their busy schedules. Furthermore, participants can receive a certificate of completion once they finish their course. The courses are available to all current SKKU students, faculty, and researchers and can be accessed with the official SKKU email address. These resources will be beneficial to students who are interested in pursuing research careers.
