 Joshua spent his early years growing up in Southern California with no clear direction on his future career path. While in college, he participated in transformative experiences through work and student involvement which set him down his journey in Medicine to serve multicultural, medically underserved communities. Subsequently, he completed medical school at Loyola University of Chicago, followed by an internal medicine residency at Harbor–UCLA and a fellowship in cardiovascular disease at the University of Arizona, all while remaining active in numerous community-focused initiatives. Aside from Medicine and community engagement, his interests include playing pickup basketball, slam poetry, boxing, and exploring/traveling while trying new foods and experiencing different cultures.

Structural Fellows

Juan Rico Mesa, M.D.

Hometown: Medellin, Colombia
Medical School: Universidad CES
Clinical Interest: Cardiogenic shock, mechanical cardiac support, left main PCI, peripheral interventions
Research Interest: Radiation safety, use of MCS for complex interventions and during early stages of cardiogenic shock

I was born and raised in Colombia, where I had the pleasure of getting my medical training and learning about healthcare disparities. My goal was always to become a cardiologist, so I embarked on this magnificent journey that I enjoy every day! For the last eight years of postgraduate training, I have spent one year at Mayo Clinic (cardiac imaging research), followed by a phenomenal internal medicine residency training at UT San Antonio, where I spent the best three years of my life. At UT San Antonio, I learned the skills necessary to become an eager proceduralist and critical-thinking physician. I decided to stay in Texas for personal reasons and pursued my cardiology training at Baylor College of Medicine, in Houston. During my training, I pursued several different teaching tracks, mentored several students, spent a great amount of time in the Cathlab and CCU, and helped on the fellows planning committee of the First Critical Care Cardiology (CCC) Educational Summit at the University of Minnesota. Despite my passion for CCC, my goal is to become an interventional cardiologist and hopefully create my cardiology practice one day. Outside of medicine, I love grilling, mountain biking and watching Formula 1. My family lives in Colombia, and I am very lucky to have a sister who will become a plastic surgeon one day. A few words that describe me: passionate, hardworking, resilient and intellectually curious. I am excited about my new training at Hopkins, and I am excited to provide exceptional care during my next two years of training.

Research Interest: Disparities in cardiovascular disease outcomes and access to advanced therapy

Born and raised in Nigeria, Kelechi moved to the United States to study public health at the Harvard Chan School, where he completed a master’s degree in global health and a doctorate in public health. He subsequently moved to Washington, D.C., for an internal medicine residency at Howard University Hospital and then to Atlanta for a cardiology fellowship at Morehouse School of Medicine. His research interests focus on outcome disparities in thromboembolic cardiovascular diseases. He is interested in a career that combines clinical work in interventional cardiology with leadership roles in the public and private health-care sectors. Outside of work, he enjoys traveling and exploring new cultures, reflecting his global outlook and commitment to diverse experiences.

Sports Cardiology Fellow

Kellen Knowles, M.D.

Hometown: Nassau, Bahamas
Medical School: Johns Hopkins University School of Medicine
Clinical Interest: Preventive cardiology
Research Interest: Medical devices, mHealth, application of mHealth and medical devices to improve primary and secondary prevention strategies

I was born and raised on New Providence, a 7x21-mile island off the coast of Florida, which is a part of the 700-island archipelago of the Commonwealth of The Bahamas. I attended Purdue University, where I studied biomedical engineering, and during graduate school, I realized I had an interest in clinical medicine. It was in medical school that I discovered a love of cardiac physiology and a desire to combine my interests in engineering with cardiology. I love to travel and met my wife in Germany. We have two children. My wife is definitely the secret of my success and my children inspire me to keep fighting to maintain balance in my career pursuits. Besides traveling, I enjoy scuba diving, backpacking, snowboarding, tennis, volleyball, playing board games, lifting weights and quality time with friends.
