Assistant Professor of Medicine

Johns Hopkins University

Center for Inherited Heart Disease

I am a physician scientist with a research focus on stem cell biology, heart regeneration and developmental cardiology. I received my BSc in Biology and my Medical Degree from the University of Crete in Greece. Then I moved to Boston MA, where I was a post-doc at Harvard Medical School and completed my residency at Boston University and my cardiology fellowship at Johns Hopkins. During my time at Hopkins I was a post-doc in Dr. Chulan Kwon and David Kass labs.

Currently, I treat patients with cardiac disease at the Johns Hopkins Hospital and I dedicate the majority of my time brainstorming ideas with members of the lab and getting fascinated by transcriptional regulation, heart development and regeneration. Outside the lab I enjoy playing legos and board games with my son and wife, wine tasting, guitar playing and watching artistic movies.

Research Assistant

I was born and raised in Burma where I studied medicine at the University of Medicine Mandalay. I completed my PhD training at the Glasgow Caledonian University where I conducted research about the role of connexin43 in pulmonary hypertension. I was trained as a postdoctoral fellow for 2 years at the University of Maryland Baltimore where I conducted hypertension research where I manipulated myosin phosphatase regulatory subunit (Mypt1) to lower blood pressure through smooth muscle sensitization to NO/cGMP-mediated vasodilation. Currently, I am a postdoctoral fellow in the Tampakakis lab where I study the role of a cardiac enhancer in the development of heart failure. Outside of lab, I enjoy outdoors, listening to music and watching snooker games.

Kwaku K. Quansah

Johns Hopkins Cellular & Molecular Medicine Graduate student

I am a Ghanaian American who completed his undergraduate degree in General Biology at the University of Pennsylvania, Philadelphia. During my time at Penn, I trained in the labs of Andrew Vaughan PhD, David Frank MD. PhD and Lisa Young MD where my interest in developmental and regenerative biology was nurtured.

In the Cellular and Molecular Medicine Program at JHU, I am interested in the role of the cross-talk between peripheral neurons and the heart in homeostasis and disease. I am also the co-founder and co-president of CMM’s PATCH peer mentor program.

During my free time, I like to run by the Baltimore waterfront, explore music and fine art. 


I received an undergraduate degree in Biomedical Engineering (BME) from Rutgers University, where I discovered my career interest falls on developing novel therapeutics to improve human lives. Later, I moved to Baltimore and received a master’s degree in BME from Johns Hopkins University. Currently, I am currently a graduate in the Tampakakis lab, where I am exploring the role of mRNA modifications during heart development.


Outside the lab, there are some fun facts about me: 1) I have an identical twin sister; 2) I also have a chubby cat whose nickname is Donggua (Means winter melon in Chinese).

I completed most of my education in India, including a bachelor’s degree from D.Y. Patil, Mumbai. Later, I worked in the field of immunology at the Indian Institute of Sciences, also known as IISc, which ignited my passion for research. I recently earned my master’s degree in Biotechnology from Johns Hopkins University. I joined the Tampakakis lab in December 2019 as a research assistant. My main project involves investigating the mechanism of stem cell regenerative therapies for cardiac disease using a “power-switch” in human stem cell-derived cardiomyocytes.

Having been born in India, I am an inborn food lover. I love traveling, spending time with friends and loved ones, and appreciate good music and movies.

Sheetal Bajpayi

BA/MSc Candidate

I am a master's student at Johns Hopkins Krieger School of Arts and Sciences. I completed most of my schooling in Singapore and moved to India for a Bachelor's in Biotechnology. I have been fascinated by the field of regenerative medicine and stem cell biology and I joined the Tampakakis lab in August 2021.

I am currently working on projects focusing on cardiovascular epitranscriptomics and the use of stem cell-derived cardiomyocytes for heart regeneration. 

I love outdoor activities and enjoy photographing while I’m at these. Apart from that, being environmentally conscious is something that really matters to me.
