A biosketch is a brief summary of you or someone else's professional /educational accomplishments, publications, and affiliations--an abbreviated curriculum vitae--meant to highlight important aspects of your training, experience, and areas of interest.In plain words...it's a "light sketch" of a persons life.
Biography:
1. An account of a person's life written, composed, or produced by another:a film biography of Adlai Stevenson; an oral biography.
2. Biographies considered as a group, especially when regarded as a genre.
A biography is about someone else while an autobiography is about one's self. So an autobiographical sketch would be a biosketch of your own life while a biographical sketch is a biosketch of anybody else's life.
