Sheikh A. Umar, Ph.D.

About

Sheikh Umar Ahmad, originally from the picturesque valley of Kashmir in the foothills of the Himalayas, holds a doctoral degree in Sciences (Biotechnology and Molecular Biology) from the Academy of Scientific & Innovative Research (AcSIR), Ghaziabad, India. He completed his Ph.D. research in 2021 at the CSIR-Indian Institute of Integrative Medicine, Jammu & Kashmir, under the mentorship of Dr. Sheikh Tasduq Abdullah. During his doctoral studies, Umar focused on understanding the interplay between autophagy and the DNA damage response in regulating ultraviolet-(B)–induced skin photodamage. Currently, he is a Postdoctoral Research Associate at the McArdle Laboratory for Cancer Research, School of Medicine and Public Health, University of Wisconsin-Madison, United States. His research now centers on unraveling the molecular genetics of papillomaviruses.
