Early career scientists are often told that networking is important for future career prospects and mobility. Often, this comes in the form of a nudge to attend university seminars, events for local scientific professionals or national conferences. These are typically great for meeting scientists working in your city or country – but developing an international network can often be much more difficult. First, scientists are most often around others working at their university or research centre, making this their primary network. Second, travel to attend international conferences may be cost-prohibitive, especially for early career scientists. Finally, connecting with colleagues outside of the country may not be on the radar of students and postdocs, or may seem overwhelming at that stage of a scientific career.
