All researchers need to find, use and disseminate information. Social media has many tools that allow you to do this, and increase your research profile in the broader community.
Outlined below are just a few of the many tools available. A more comprehensive list is available from Professor Andy Miah's A-Z of Social Media for Academia.
While not a social media tool, The Conversation is an independent source of news and insights, written by academics and researchers and available online free of charge to the wider community. The site's charter includes "giving experts a greater voice in shaping scientific, cultural and intellectual agendas by providing a trusted platform that values and promotes new thinking and evidence-based research."
