As scientists, we are familiar with giving talks.  We can give a meeting talk of ten minutes, a group meeting for 30 minutes or a department seminar of an hour.  We make our slides, we prepare notes, we practice and then we stand before our audience and present our work.  This process is not that much different than talking about yourself, but the data changes to:  Who are you?  What do you do?  What are your research interests?  What are your career interests?  Now the trick is, can you do it effectively in 30 seconds?  What about two minutes?&n
