Dr. DeAngelis’ program of research utilizes a systems-biology-based approach to understand disease mechanisms in both Mendelian and complex blinding conditions, including age-related macular degeneration (AMD), glaucoma, diabetic retinopathy, and hypertensive retinopathy; and comorbid conditions (Alzheimer’s disease, cardiovascular disease, and diabetes). This translational research is funded by the NIH, private foundations, and the pharmaceutical industry. She is ultimately focused on identifying mechanisms and potential targets for treatment in these disease areas, across their stages of development.
To enhance translational efforts, her laboratory and colleagues have created a well-characterized fresh human donor eye bank of ocular tissue, blood, serum, and plasma. Using this resource, contrasting healthy eyes with diseased eyes (deeply phenotyped) has helped delineate potential disease mechanisms. Dr. DeAngelis leverages genomic approaches including, single-cell RNASeq, miRNAseq, bulk RNA-Seq, single nuclei ATAC-Seq, allele-specific expression, epigenetic and statistical/bioinformatics tools to functionally characterize disease mechanisms. She has published the only standardized phenotyping protocol for human donor eyes specifically used for biochemical and molecular studies. The success of the eye bank is dependent on close collaboration with several board-certified ophthalmologists and fellowship-trained specialists.
Dr. DeAngelis has extensive experience in leading scientific teams for patient ascertainment and recruitment in patient populations within the United States and globally. This research helps us to understand both environmental and genetic drivers of disease, including the importance of protective alleles and their association with lower disease risk burden. The success of these studies has been in large part dependent on collaboration across disciplines, and significant community engagement to inform design and appreciation of the clinical/public health implications of the work.
Dr. DeAngelis is is committed to and has extensive experience teaching and mentoring the next generation of scientists and clinician-scientists. She is a mentor and advisor to undergraduates, graduate students, medical students, fellows, and junior faculty. She teaches classes for neuroscience, human genetics, ophthalmology, biochemistry, molecular biology, and epidemiology.
Dr. DeAngelis has over 100 publications, serves on several journal editorial boards, and serves on the steering/leadership committee for the International AMD Genetics Consortium, sponsored by the NEI/NIH; and also the Scientific Oversight Committee for The Global Eye Genetics Consortium (NEI/NIH). She also chairs/serves on several NIH study section review panels, the Department of Defense, and foundation grant review panels.
