Dr. Dayal earned her PhD from All India Institute of Medical Sciences, New Delhi, India. Thereafter she joined the laboratory of Dr. Steven Lentz in the Department of Internal Medicine, University of Iowa, for postdoctoral studies. She pursued her research interests in delineating mechanisms of thrombosis associated with cardiovascular risk factors and developed an independent research program in aging and obesity/prediabetes associated platelet activation and thrombosis. She is also actively studying COVID-19, long COVID and cancer as the mediators of thrombosis. Her husband Abhas Kumar is a software engineer. She has a daughter Deeksha, with a computer science major, who loves Indian dancing, western music and teaching/training younger kids. Her son Aadarsh is studying Finance and Business and enjoys playing bansuri (Indian flute), western music and discussions on political agenda and world economy.

Research Assistant Professor

Contact Information: azaj-ahmed@uiowa.edu

Dr. Azaj Ahmed is from Islampur, West Bengal, India. He studied Biochemistry at Aligarh Muslim University, Aligarh, India, earning his Bachelor's, Master's, and PhD degrees. Following his PhD, Dr. Azaj pursued his first postdoctoral training at China Medical University, Taiwan, and later at Jamia Millia Islamia in New Delhi, India. Eventually, in 2021, he became part of Dr. Dayal's lab at the University of Iowa. In this position, his research focuses on hematology, particularly studying thrombosis as a disease model. He investigates platelet bioenergetics and signaling mechanisms associated with thrombosis in in vivo mouse models and clinical settings. His attention is on risk factors like aging, viral infections, overweight/obesity, and prediabetes, which are known to increase susceptibility to thrombotic complications. He lives in Iowa City. He likes spending time with his friends.
