Science Career Tip: To build up your academic reputation, start assisting your supervisor and/or senior colleagues with peer reviews. Although it's time consuming, learning to critique other scientists' work can help you refine your own.
For instance, you'll gain insights to new research before it is widely known. You'll see how other researchers present their data. You'll develop a skill for being critical and yet tactful. You'll learn how to make strong arguments and justifications of your statements. You'll get quicker at noticing inconsistencies and technical flaws.
Evaluating manuscripts can hone your own research abilities, demonstrate transferable skills, and position you as an expert in your field!
