Yevgeniy grew up in New York, but decided to transplant himself to the West Coast for his PhD studies at the Scripps Research Institute, where he studied mechanisms of gene regulation in the immune system. Recently, Yevgeniy again found himself in New York City, pursuing a post-doctoral research project in oncology. Realizing that his true passion was writing, Yevgeniy decided to leave academia and pursue science writing as a freelancer to share his passion for fostering communication between the scientific community and the public. In his spare time Yevgeniy works as a Krav Maga self-defense instructor.
