Biography

Dr. Hufnagel is an adjunct investigator with NHGRI’s Center for Precision Health Research, whose primary appointment is as a 2021 Lasker Clinical Research Scholar and director of the National Eye Institute’s Ophthalmic Genomics Laboratory. His research focus is on understanding the mechanistic basis of human heritable ocular disorders, including those in children and adults with rare eye diseases and syndromes. He uses a translational approach combining clinical molecular approaches and developmental biology to improve diagnosis and establish gene:disease and genotype:phenotype relationships. Using genomics, stem cell engineering, and gene editing, he seeks to establish patient-centered disease models for translational and preclinical studies. Dr. Hufnagel’s research includes clinical molecular diagnostics from patients at the NIH Clinical Center and through the eyeGENE® program to develop population genomic datasets for rare eye diseases, coupled with scientific investigations validating candidate disease genes and mapping disease-relevant noncoding genome of eye tissues. Model systems include human cells, mice, zebrafish and foveate lizards.

After receiving his M.D. and Ph.D. from the University of Cincinnati, Dr. Hufnagel completed his pediatrics and clinical genetics residency at Cincinnati Children’s Hospital, followed by fellowships in clinical ophthalmic genetics at the National Eye Institute and clinical molecular genetics and genomics at NHGRI. In addition to being a board-certified pediatrician, Dr. Hufnagel is board-certified in clinical and clinical molecular genetics and genomics.
