    Maryam Amirahmadi

    Postdoctoral Scholar, Cardiovascular Medicine

    BioDr. Maryam Amirahmadi is a microsurgery expert and postdoctoral research fellow at Stanford Cardiovascular Institute. She obtained her Doctor of Medicine (MD) degree from Hamadan University of Medical Sciences. After more than a year of experience as a Family and Emergency Physician, she spent around 4 years at the Department of Cardiovascular Surgery of Shiraz University of Medical Sciences where she served as a pediatric and adult Cardiac Intensive Care physician and received training in cardiovascular surgery at Namazi and Faghihi hospitals. She then spent a year in the Department of Vascular Surgery at the University of Miami, Miller School of Medicine, serving as a postdoctoral researcher and performing microsurgery on animals, with her research focused on therapeutic strategies to improve neovascularization after limb ischemia. Dr. Amirahmadi joined Stanford Cardiovascular Institute in 2022 where she is now a postdoctoral research fellow under the supervision of Prof. Philip S. Tsao, a renowned cardiovascular scientist. Her research interests and practical expertise include Microsurgery, and the effect of e-cigarette vaping on factors of inflammatory or immune pathways that can subsequently be related to the molecular mechanisms involved in angiogenesis and arteriogenesis in the murine model of hindlimb ischemia, as well as the mechanisms of e-cigarette and nicotine’s effects in augmenting Abdominal Aortic Aneurysm (AAA) in rodent models of aortic aneurysm, including porcine pancreatic elastase-induced AAA. Dr. Maryam Amirahmadi and her colleagues are currently investigating the transgenerational effects of vaping/nicotine on abdominal aortic aneurysm (AAA) risk.

    Daniel Kwasi Amponsah

    Postdoctoral Medical Fellow, Cardiovascular Medicine
    Fellow in Medicine - Med/Cardiovascular Medicine

    BioDr. Daniel Amponsah was born and raised in Loma Linda, California. He graduated with a BS in Biochemistry from Pacific Union College in Northern California and received his MD from Loma Linda University School of Medicine where he graduated AOA. He completed his internal medicine residency at Massachusetts General Hospital and was appointed the Simulation Chief his senior year. He is interested in pursuing an academic career in interventional cardiology with a focus on outcomes and health disparities. Prior research work has explored outcomes in ischemic time in patients with cardiogenic shock and STEMI with Dr. Anthony Hilliard, disparities in the management of aortic stenosis alongside Dr. Sammy Elmariah, defining type 2 MI using coronary CT with Dr. James Januzzi. He is presently engaged in assessing the potential applications of angiography-derived FFR and IMR across various coronary disease syndromes with Dr. Bill Fearon and investigating disparities in advanced structural interventions with Dr. Celina Yong.
