Chris Hoag

After many years as a copywriter, media analyst and graphic pundit completely focused on supporting scientific marketers, I’ve come aboard Science/AAAS to help leverage new technologies and practices in communication.

Telecommunication and software have changed the way we communicate and interact. My entire career has been devoted to studying communication and media, beginning at a traditional ad agency and progressing to the leading edge of information design.

I’ve been fortunate to work with the leading players in life science manufacturing, media and distribution, and to have experienced significant changes in the market as they have occurred. I’m looking forward to bringing a consultative and widely accomplished perspective to today’s marketers.

She made the move to publishing and advertising sales when she joined Science/AAAS in 2000.   Having led the Recruitment Advertising team, first in Europe and then the US, she is experienced in helping organizations recruit, brand, and engage with the Science audience across multiple platforms.  She now heads up Global Advertising Sales and is proud to be part of an organization that is dedicated to advancing science for the benefit of all people. Tracy is a country girl at heart and was once crowned Dairymaid of Norfolk, but has never milked a cow in her life!
