Tasnim Aziz, Science

Tasnim Aziz ​ Tasnim Aziz was born in Philly but grew up in various parts of America and Bangladesh, her family’s country of origin. Tasnim received a B.A. in Biology with Honors and instructional certifications in Biology and Chemistry from Bryn Mawr College. During college, she was awarded the Noyce Fellowship, a National Science Foundation award for Math and Science majors who are pursuing a career in urban education. Tasnim also holds a Master of Environmental Studies with a Concentration in Environmental Biology from the University of Pennsylvania. She teaches students various science courses which include: BioChem, Environmental Science, Botany, and Human Anatomy. Her goal as a science teacher is to nurture young scientists (AKA students) to make meaningful connections between the field of science and their own lives. Tasnim is also a superhero nerd who encourages her young scientists to explore their own superpowers to make responsible choices and take thoughtful risks to solve problems. On June 2017, Tasnim was recognized by the Grid Magazine and the University of Pennsylvania as “The capeless crusader” for engaging her students in environmental justice work in her courses. Shortly after, Tasnim was selected to participate in Education for Sustainability (EfS), a National Science Foundation funded program, in which she will be designing project-based curriculum that revolve around real world environmental sustainability issues. Through the EfS program, Tasnim will engage her students in building a sustainable farm and school campus. As a result, she hopes her students will be taking the initiative to save the planet while applying their understanding of STEM. When Tasnim is not partaking in school work, she enjoys swimming, yoga, mediTEAtion, hiking, ethnobotany, the food network, Bollywood movies…and did she mention superheroes?
