Martina G. Efeyini became an ASBMB Today contributor in 2014 and now is a columnist who writes about alternative science careers. She is a toxicologist, science communicator and STEM advocate who is passionate about sharing resources for the next generation of scientists. She earned her bachelor's degree in toxicology from the Pennsylvania State University and her master's degree in toxicology from St. John’s University. Her experiences as a mentor, researcher and writer inspired her to combine her passions (STEM, communication and advocacy) to create Mademoiselle Scientist, an online resource for students and scientists. Martina’s commitment to the next generation shines through her work as a program assistant at the University of Maryland, Baltimore, CURE Scholars Program and outreach coordinator at Understanding Interventions. Outside of science, Martina loves spending time with her family, reading and cooking plant-based meals.
