Principal Investigator


Paul Burridge, PhD
Assistant Professor, Department of Pharmacology and Center for Pharmacogenomics

Dr. Burridge is an assistant professor in the Department of Pharmacology at Northwestern University Feinberg School of Medicine. He is a founding faculty member of the Center for Pharmacogenomics, and a member of the Center for Genetic Medicine, the Lurie Cancer Center, the Feinberg Cardiovascular and Renal Research Institute, Northwestern University Clinical and Translational Institute, and the Stem Cells and Regenerative Biology Initiative. Dr. Burridge began his career in genomics and bioinformatics at the Sanger Institute working on the human and mouse genome projects. He completed a PhD in Human Stem Cell Biology at the University of Nottingham before pursuing postdoctoral fellowships at the Johns Hopkins University in Pediatric Oncology and then at Stanford University in Cardiology before becoming an Instructor in Cardiovascular Medicine at Stanford. For more than 15 years, Dr. Burridge has worked on the applications of human pluripotent stem cells (both hESC and hiPSC), concentrating on culture and differentiation methodologies, regenerative medicine, and disease modeling, specifically the pharmacogenomic and molecular mechanisms of chemotherapy-induced cardiomyopathy and heart failure. Dr. Burridge is the recipient of the NIH NHLBI Pathway to Independence Award and a Dixon Young Investigator Award. In 2016 Dr. Burridge was elected a Fellow of the American Heart Association in Genomic and Precision Medicine.

Adam J. T. Schuldt, MD, PhD
Clinical Research Fellow
(312) 503 4765

Adam earned his PhD in Biomedical Engineering from Stony Brook University investigating the use of adult stem cells for cardiac regeneration. He subsequently earned his MD from the University of Michigan Medical School. He went on to complete residency in Internal Medicine and clinical fellowship in Cardiology at Northwestern University before doing postdoctoral research in the Division of Vascular Surgery at Northwestern. He began his postdoctoral research in the Burridge Lab in 2016, where he is continuing his interest in the development of cell-based therapeutics for cardiovascular disease.


Deborah Sung, MD
Clinical Research Fellow

Deborah earned her MD from the University of Washington School of Medicine and went on to complete her residency and chief resident year in Pediatrics at The Children's Hospital at Montefiore/Albert Einstein College of Medicine. She is currently a Pediatric Critical Care Fellow at Ann & Robert H. Lurie Children's Hospital of Chicago. She joined the Burridge Lab in 2017 and is interested in the application of precision medicine in cardiovascular disease.

Research Staff


Conrad Epting, MD
Attending Physician, Critical Care and Cardiology, Associate Professor of Pediatrics and Pathology

Training: Strategies to promote cell and tissue regeneration remain at the forefront of cardiovascular biology. I have a scientific background in myogenic stem cells and skeletal muscle regeneration. At Northwestern University, I spent some years studying myocardial targeting by pathogens, specifically T. cruzi, the leading cause of myocarditis and heart failure in endemic regions of Latin American. However, as a practicing cardiac intensivist, my research program has shifted to the study of pediatric heart failure. I am interested in the response of resident progenitor cells to aging and heart failure. We suspect an epigenetic basis for cardiac progenitor cell activation in patients with premature ventricular failure secondary to exposure from neurohormonal axis activation. In partnership with the pediatric cardiovascular surgeons we created a cardiac biorepository to further translational research across the institution. Through collaboration with the Burridge laboratory I hope to determine the differentiation potential of resident cardiac cell populations and optimize direct reprograming of primary cardiac fibroblasts. We hope that knowledge of the phenotype of resident cells and their reprograming potential will enable clinical cryobanking, ex vivo reprogramming, and in situ cell manipulation to extend the lives of children and young adults with progressive heart failure from cardiomyopathy and congenital heart disease. We have implementing the Fontan Futures Initiative to optimize atrial tissue cryopreservation and enable clinical grade biobanking on behalf of patients with single ventricle physiology who are likely to progress to end-stage heart failure through a generous endowment from the Mathews Center for Cellular Therapy at Northwestern Medicine.
