Graduate BME students are tackling heart disease and training to become leaders and innovators in cardiovascular research
In 2023 the Wallace H. Coulter Department of Biomedical Engineering launched a new program designed to train the next generation of leaders in cardiovascular research. Five first-year graduate students formed the first cohort that fall.
Currently, there are nine students in the Cardiovascular Biomechanics Graduate Training Program at Emory and Georgia Tech (CBT@EmTech). The program offers two years of training in an assortment of disciplines, including cardiovascular biomechanics, mechanobiology, medical imaging, computational modeling, medical devices, therapeutics discovery and delivery, and data science.
The current cohort of fellows in the Coulter BME Cardiovascular Biomechanics Graduate Training Program at Emory and Georgia Tech are engaging in multidisciplinary training in areas such as cardiovascular biomechanics, mechanobiology, medical imaging, computational modeling, medical devices, therapeutics discovery and delivery, and data science.
“The goal of the program is to stimulate interdisciplinary training,” so we expose the students to multiple areas of research,” says Hanjoong Jo, CBT@EmTech director, Wallace H. Coulter Distinguished Professor.
“And we have a very diverse group of trainees interested in various aspects of cardiovascular research and medicine,” Jo added. “Four out of five students from our first cohort already have secured prestigious fellowships, demonstrating the caliber of the trainees in the program.”
The students from that cohort brought a wide range of experiences, interests, and ambitions to the program. Now in their final months as CBT@EmTech trainees, they took time to share their stories.

As a researcher, I am challenged to explore the unknown. Moreover, my role as an engineer is rooted in using knowledge that has already been conceptualized. Combining these perspectives as a biomedical engineer has led me to pursue research with an emphasis on improving human health.
Today, cardiovascular diseases represent the global leading cause of death. While this glaring statistic indicates the egregious burden of cardiovascular diseases, my parents' lived experiences with cardiovascular diseases is what drives me to use my life’s work to address critical challenges at the intersection of the cardiovascular field and biomedical engineering.
My research seeks to alleviate cardiovascular diseases by using nanoparticles to target endothelial cells, which line the innermost layer of blood vessels and contribute to blood vessel function. The Cardiovascular Biomechanics and Mechanobiology Program at Emory (CBT@EmTech) has given me an avenue to pursue this research.
Through my CBT@EmTech co-mentorship, I have developed a foundation in endothelial cell biology and atherosclerosis. I have also been challenged to think critically about how my research benefits both science and society through my exposure to prominent cardiovascular researchers. My experiences with CBT@EmTech have made me eager to use my training to pursue a postdoc in the and eventually lead a lab answering critical questions in cardiovascular research.

As a PhD student in the Jo Lab, I am studying how disturbed flow influences transcriptional regulation in endothelial cell reprogramming and atherosclerosis. Our goal is to identify and develop therapeutics that target non-lipid residual pathways contributing to this widespread and deadly disease.
I initially became interested in this line of research due to a family history of cardiovascular disease. As an undergraduate, I worked in a tissue engineering lab where I employed stem cell and tissue engineering methods to model the circulatory system. A desire to further explore the role of mechanosensitive genes and proteins in cardiovascular disease led me to pursue a PhD in this field.
One of the most valuable aspects of the CBT@EmTech program has been the opportunity to connect with a network of students and faculty who are leaders in cardiovascular research. Through monthly meetings, we share our work and gain insights into the diverse engineering applications our interdisciplinary program brings to the field, with the common goal of improving cardiovascular health.

I've always had a passion for helping people and I feel that I’m doing this through my research on aortic valve tissue engineering for pediatric patients. Aortic valve disease is found in 1-2% of live births, because of congenital heart defects or infections. Current valve replacements are limited — for one thing, they’re incapable of growing and remodeling with the patient. This presents a need for a new tissue-engineered valve that can address these challenges. In the Davis lab, we’re working on a tissue engineered heart valve to provide a better, long-term solution.
Throughout my time in the CBT@EmTech program, I've gained a range of knowledge in the cardiovascular space, learning about atherosclerosis, peripheral artery disease, valve disease, as well as computational and imaging techniques to help solve some of these problems. As part of the program, we are also required to take an Advanced Seminar class in the cardiovascular area.
Through this class, I was able to participate in some interesting clinical observations in the Emory University Hospital cardiology department. For example, I watched a cardiologist perform a transesophageal echocardiogram. The doctor was checking for heart blockages on a patient who had atrial fibrillation. This procedure was followed by a cardioversion to restore a normal heart rhythm. This was a profound demonstration of biomedical technology in action that left a lasting impression on me.

October 2024 marked the three-year anniversary of my uncle’s passing due to complications from a mild heart attack. His angiogram showed 30% vessel blockage, leading to heart surgery. Sadly, he suffered a brain stroke days later, resulting in deteriorating speech, muscle movement, and eventually death at 48. This personal tragedy brought urgency to my research questions: Can the risk of complications following cardiovascular treatments be predicted? Can underlying cardiovascular pathology be treated before it progresses to a heart attack or stroke? Was my uncle’s death preventable? These questions drive my cardiovascular research, focused on predicting post-procedural heart valve outcomes through computational modeling.
Being part of the prestigious CBT@EmTech program at Emory and Georgia Tech has significantly advanced my research journey. Learning from fellow trainees, presenting my research, and attending academia-focused workshops (like one about grant writing) have helped me stand out in heart valve computational modeling. The program, along with my PI, Dr. Lakshmi Prasad Dasi, and co-PI, Dr. John Oshinski, has provided the resources needed to translate my research from the lab to the clinic through regular meetings with clinicians and data transfer to and from hospitals. I am grateful for the opportunity to pursue my long-term goal of predicting risks of complications before cardiovascular treatments and helping prevent adverse clinical outcomes like those experienced by my uncle.

Peripheral artery disease (PAD) occurs when atherosclerotic plaque accumulates in limb arteries, blocking blood flow. Current interventions limit disease progression, but surgery is often needed to prevent critical limb ischemia. A less invasive approach promotes angiogenesis and arteriogenesis to strengthen collateral vessels and bypass blockages. The Hansen Lab studies satellite cells (SCs), which repair muscle fibers and release growth factors, as a potential PAD therapy.
My research focuses on improving the delivery of SCs using a special fibrin scaffold in a mouse model of blocked blood flow in the legs. By adjusting the properties of the fibrin scaffold, we can create an environment that helps these cells grow and renew themselves. We study how quickly the fibrin forms to ensure the cells stay where we inject them and how it breaks down to keep a steady supply of renewing SCs. We believe that with fibrin, the cells will move into the damaged tissue, repair muscle fibers, and release growth factors to encourage new blood vessel growth.
The goal is to create alternative treatments for PAD that prevent disease progression and improve patients' quality of life.
The CBT@EmTech program has given me a supportive network of peers and mentors, enhancing my growth as a researcher. The program chairs have tailored the curriculum to our needs and allowed us to shape it. For example, I’ve had the privilege of co-planning our biannual retreat. We recruited guests for two panels and invited a guest speaker for a storytelling workshop. This retreat shows how the program imparts knowledge beyond research, aiming to improve our scientific storytelling and self-presentation skills, valuable for any career.
