Damir was born and raised in Samarkand, Uzbekistan. His passion for development of new therapies for incurable human disorders lead him to pursue B.Sc. in Biomedical Sciences from Western Michigan University (2010-2014). After the second year in college he joined the lab of Dr. Donald Kane where he used zebrafish as a model organism to study ‘zombie’, an early arrest phenotype where embryonic cells fail to divide. He mapped the zombie phenotype to a small region on chromosome 2 which contains the important cell cycle gene CDC20. After graduation, Damir joined the lab of Dr. Joseph Gleeson at The Rockefeller University/UCSD (2014-2017) to better understand the genetic causes of inborn brain disorders in children around the world.
