One of only a handful of African Americans to earn a PhD in entomology, Dr. Sammy Ramsey is an inspirational science leader and communicator who has defied the odds to achieve his dreams and is a testament to the power of grit, determination, and an unwavering commitment to one’s purpose. When people said he didn’t have what it took to make his mark in entomology, he proved them wrong by making a breakthrough discovery in the field of bee research — one that could potentially reverse a devastating pandemic in bee populations.
