Assistant Professor of Medicine, Genetic Medicine and Biomedical Engineering

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.

Nicole Cheng, MSc


I completed my BS and MS in molecular medicine in National Tsing Hua University in Taiwan where I fell in love with cell imaging before moving to Baltimore. I am a 2023 PhD student in Johns Hopkins Biomedical Engineering program Tampakakis lab where my focus of research is exploring the role of epitranscriptomics in cardiac development and regeneration. 

Outside the lab, I enjoy cooking and exploring cafes and restaurants. Horse riding is the exercise that best helps me relax. 

Johns Hopkins BME Graduate student

Shunyao Lei, MSc


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).

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.
