Deanna MacNeil, PhD

Deanna earned their PhD from McGill University in 2020, studying the cellular biology of aging and cancer. They have an endless curiosity about DNA ends (telomeres), and in addition to telomere research, Deanna has a multidisciplinary academic background ranging from chemistry to metacognition to microbiology. Deanna is a medical writer and budding science communicator. They joined The Scientist's Creative Services Team in 2022 as an intern.
