Your researcher profile is an individual Internet profile that provides a user firendly and efficient way of showcasing your work.
Unique author identifiers are useful for the following reasons:
In an increasingly competitive research and scholarship environment, how do you distinguish yourself from someone? If your institutional affiliation and/or contact information changes, how is the link between you and your scholarly work maintained? The solution is creating a researcher profile.
A profile pulls all your research and publications together in one place, mitigating common problems that often arise in searching. Such problems can include variations in authors' names or difficulty in narrowing a search down easily when an author has a common name.
If a researcher has worked with multiple granting agencies, research groups, or institutions, a research profile will also make their research easier to find.
