A personal biography includes an introduction about yourself and your history. It features your achievements, credentials and notable contributions. Biographies tend to be concise and only contain relevant information angled to a specific audience.
Professional biographies tend to be written in the third person and should not contain personal statistics such as hobbies and information about your family. Casual information can be included if the biography is a project for a school or a similar organization.
First, introduce yourself with a simple statement talking about your most recent relevant work experience. List the areas of expertise you have, if any. List your educational history after the introductory statement. Include the names of the degrees you have earned, the institutions you went to and other relevant experience such as earned certificates and the names of professional associations that include you as a member. The next paragraph contains notable awards earned. Instead of listing all the awards you received, keep your list relevant to the biography's intended audience.
End the biography with a brief statement highlighting current or future projects. Include your current contact information and state of residence in the last sentence. Edit your professional biography when your experience or achievements change to show current information.
