Biologist & Stress Expert, Author


“Rebecca’s keynote was dynamic, thought-provoking and action inspiring. It resonated with me and our team in such positive ways, causing us to really look at the blind spots and specific ways to create behavior change in both our lives and businesses. We received more positive feedback from her talk and requests for a copy of her talk than any of the other speakers.”-Director of Business Affairs, Consolidated Assurance

Called “transformative” by the National Science Foundation, evolutionary biologist Dr. Rebecca Heiss’s breakthrough research examines the prehistoric fears and primitive instincts that our human brains have subconsciously carried forward into our complex, modern world. Sharing science-backed explanations and thought-provoking storytelling, she shows us how to overcome the reflexes that served us well 20,000 years ago but sabotage us today. Whether you are a corporate leader looking to build and lead stronger teams, an organization seeking to understand the ingrained instincts behind unconscious bias, or simply wishing to manage stress and anxiety and adopt a more successful, positive mindset, Dr. Heiss’s highly interactive talks will rock your perceptions about how people universally think, behave, and interact.

Dr. Heiss is the author of the book, Instinct: Rewire Your Brain with Science-Backed Solutions to Increase Productivity and Achieve Success, which has been described as “a revolutionary approach to unlocking your innate ability to achieve success in business and in life.” She is also the founder and CEO of icueity, a continuous 360 review app that provides users with ongoing “fearless feedback” and challenges them to grow in self-awareness. She taught at the South Carolina Governor’s School for Science and Mathematics and later was recruited to be among the founding faculty members to develop a startup school to nurture entrepreneurial minds and approach learning through impact. Dr. Heiss holds a BS and MS in Biology from Binghamton University and a PhD in stress physiology from University of Memphis.

Her talks have inspired audiences around the world, including organizations such as Charles Schwab, ADP, SHRM, and Case Western Reserve University. Believing that “the scariest thing is living a life governed by fear,” Dr. Heiss challenges us to BECOME FEAR(LESS)™ while providing the tools to achieve it.

While she incorporates fascinating scientific research, make no mistake — this is no boring academic lecture. Audiences are immediately won over with Rebecca's warmth, surprising humor and palpable energy that brings crowds to their feet. Through storytelling and interactive interludes, Rebecca's "fearless" message inspires hope and actionable insights to train our brains to work for us, rather than against us in times of uncertainty. Audiences leave with actionable takeaways on how to overcome their own biology, take control of stress and anxiety, be more effective and productive, break through the barriers to optimal performance — and live happier, fear(less) lives.
