Dr. Helen Fisher is a pioneer in examining the neurochemistry of personality. She is an internationally renowned expert in biological anthropology, brain chemistry, neuroscience, and personality styles. A professor at Rutgers University and Senior Research Fellow at The Kinsey Institute, she’s also the most referenced scholar in the field of love and relationships in the world today. Her most recent book, Why Him? Why Her? Finding Real Love by Understanding Your Personality Type (Jan. 2009, Henry Holt), examines Dr. Fisher’s biological theories of personality. It stems from her work as Chief Scientific Advisor for Match.com, through which Dr. Fisher’s original inventory has been taken by over 16 million people in 40 countries. Her findings have been validated using brain scanning (fMRI) as well as more traditional methods in published academic articles.
