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.
