Dr. Taylor is a Harvard trained and published neuroanatomist. Her area of expertise involves understanding how our brain creates our perception of reality and how we can recover from neurological trauma.

In the lab, Dr. Taylor was focused on understanding the differences between the postmortem human brains of individuals classified as neuro-typical, as compared with those diagnosed with schizophrenia, schizoaffective, and bipolar disorder.

Ironically, in 1996, Dr. Taylor experienced a severe hemorrhage in the left hemisphere of her brain causing her to lose the ability to walk, talk, read, write, or recall any of her life. Based on her knowledge about the brain, through the eyes of being a neuroanatomist, she completely rebuilt her brain from the inside out. In 2008, her memoir My Stroke of Insight, which documented her experience with stroke and eight-year recovery, spent 63 weeks on the New York Times nonfiction bestseller list. It routinely remains a top seller about stroke in the Amazon marketplace.

Dr. Taylor’s second book Whole Brain Living: The Anatomy of Choice and the Four Characters That Drive Our Life, was published in 2021. The material in this book has been independently researched and found to be an Evidence Based program for helping people differentiate the different parts of who they are so they can choose to live more peaceful lives. Whole Brain Living blends neuroanatomy with psychology and teaches us how we can short-circuit our emotional reactivity and find our way to deep inner peace. This material is currently being used to help thousands of people around the world.

Dr. Taylor’s purpose in life is to educate all age groups, academic levels, as well as not-for-profit organizations and corporations about the beauty and resiliency of our human brain. She is an expert, both personally and professionally, about the neuroplasticity of our brain and our ability to not only recover from trauma, but about how we have the power to choose who and how we want to be in the world. 

In 2008 Dr. Taylor gave the first TED talk that ever went viral on the Internet, which now has well over 30 million views. Also in 2008, she was chosen as one of TIME Magazine's “100 Most Influential People in the World” and was the premiere guest on Oprah Winfrey’s “Soul Series” webcast and appeared on her TV show.
