Dr. Couser obtained his bachelor’s degree from the University of Virginia and his Medical Doctorate from the Virginia Commonwealth University School of Medicine (VCU SOM). Dr. Couser’s ophthalmology residency was completed at Howard University where he served as co-chief resident in the last year of his residency. He received fellowship training in pediatric ophthalmology and adult strabismus at Emory University. Dr. Couser received a master’s degree in biotechnology from the Johns Hopkins University and completed a residency in clinical genetics at the University of North Carolina at Chapel Hill. He is one of only a few individuals currently board-certified by both the American Board of Ophthalmology and the American Board of Medical Genetics and Genomics. CV https://www.hopkinsmedicine.org/-/media/wilmer/documents/cvs/couser-cv Research Summary My primary research focus involves the identification and management of genetic eye diseases including rare inherited disorders affecting the eyes. Research and scholarly activities have been an integral component of my career path. I have been the principal investigator on 10 clinical trial/IRB studies and a co-investigator on others, participated with several committees or advisory panels related to research activities. I have been credited with over 120 book chapter, journal article and abstract publications. In addition, I served as the primary author/sole editor for a textbook titled Ophthalmic Genetic Diseases: A Quick Reference Guide to the Eye and External Ocular Adnexa Abnormalities, 1st Edition, published by Elsevier in 2018, which is one of only a few textbooks published in this subject area. I also served as a grant review panelist for the National Eye Institute Career Development Awards.

Dr. Habela completed a Medical Scientist Training Program at the University of Alabama, Birmingham. She received her PhD in Neurobiology in 2008 and her MD in 2010. After medical school, she specialized in child neurology, and completed 2 years of pediatrics residency and 3 years of child neurology residency at the Johns Hopkins Hospital in 2015. She then completed another 2 years of training specifically focused on the diagnosis, characterization and medical and surgical management of patients with epilepsy during an Epilepsy Fellowship at Johns Hopkins. Dr. Habela’s clinic specializes in pediatric neurology and epilepsy. Her clinical focus in on the care of patients with severe epilepsy with or without other neurodevelopmental disorders that have not been easily controlled with medications. She is also focused on the genetic causes of epilepsy and other neurodevelopmental disabilities with the hope that increasing our understanding of the genetic causes of epilepsy and neurodevelopmental disabilities will improve treatment. Dr. Habela’s basic science research is focused on the genetic mechanisms regulating appropriate proliferation, migration and integration of neurons and glial cells in both the prenatal and postnatal developing brain and how aberrations in these processes result in neurodevelopmental disabilities. Her hypothesis is that deregulation of pre and postnatal neurogenesis and synaptogenesis contributes to the behavioral phenotypes observed in many forms of intellectual disability, epilepsy and autism. Her research applies what we know from human genetic studies to basic science studies examining how specific genetic changes alter neurogenesis, synaptogenesis and overall excitation / inhibition balance in laboratory model systems. Her goal is to provide a better understanding of the molecular mechanisms of these processes and, in turn, possibly identify specific targets for disease modifying treatments for epilepsy.
