Abdullah Bashar Sami

Postdoctoral Fellow

  • Sami is a postdoctoral fellow in our lab. He completed his undergraduate and master’s degrees in Genetic Engineering and Biotechnology at the University of Dhaka, and obtained a PhD in Molecular and Cellular Life Sciences from the University of Wyoming. He joined the Zanic lab in May 2023. Since then he has been investigating microtubule network architecture and the role of microtubule-associated proteins in microtubule network remodeling. He is also interested in understanding the microtubule-actin crosstalk and its implications in a cellular context. Outside the lab, he is passionate about sports, particularly cricket and soccer, and he enjoys spending quality time with his family and engaging in outdoor activities such as hiking.
