Just a few weeks after Twitter co-founder Jack Dorsey sent the platform¡¯s first tweet in March 2006, the social media network gained its first PhD student.

Indiana University computer science student Andrew Keep (), now a software engineer at Cisco, is listed among the first 100 people to have signed up to the fledgling site, which now has 320 million monthly users.

Dr Keep is still an occasional tweeter, broadcasting his thoughts on everything from home baking and everyday irritations to computer coding formulas, much like the hundreds of thousands of PhD students to have embraced the medium since then.

But some advocates of Twitter, which celebrates its 10th?anniversary on 21 March, believe its influence on PhD candidates has been more profound than just providing a way for them to let off steam or catch up with friends. For many, Twitter has transformed the PhD experience altogether, they claim.

¡°I found my PhD supervisor on Twitter,¡± explains Donna Peach (), now a lecturer in social work at the University of Salford, who runs , one of the world¡¯s largest PhD-related groups with about 26,500 followers.

Ms Peach, a social worker with 30 years¡¯ experience, began the group in June 2012 at the start of her PhD in psychology at the University of Huddersfield, as well as a related Facebook page, which now has around 30,000 members.

¡°Doing a PhD can be a very isolating experience, which is why Twitter is so valuable,¡± said Ms Peach, whose followers often share the frustrations, hardships and happier moments of their doctoral study via hashtags such as and .

¡°There are a lot of part-time PhD students who have to use their weekends to work on their PhD, so it¡¯s nice to know other people are out there making these sacrifices,¡± she added.

While has more followers on Facebook, she prefers its Twitter group owing to the lack of spam, which makes it easier to use. Ms Peach often chairs discussions and networking for certain subject areas, part of Salford¡¯s efforts to support and engage with early career researchers.

¡°It¡¯s easier for PhD students because they can just tune into what they¡¯re interested in,¡± she said of Twitter¡¯s search functions.

With so many early career academics on Twitter, the site has transformed the way researchers interact, not just online but also when they meet in person, Ms Peach claimed.

¡°People will contact each other on Twitter before a conference, saying we should meet up and share information on a certain subject,¡± she said.

Twitter has also helped researchers in difficult-to-research fields, such as sex workers or child abuse, to connect with each other and start collaborations, said Ms Peach, whose own research has focused on these topics.

It has also allowed more junior researchers to build a profile and increase the visibility of their research, she added.

¡°You can schedule tweets to appear while you are talking at a conference, so you can almost literally be in two places at the same time,¡± she said.
