The Developmental, Degenerative, and Regenerative Neuroscience (DDRN) group is dedicated to the investigation of the causes of neurological impairments throughout the life span. By understanding the molecular mechanisms regulating the development and function of the brain, we will address the causes and eventual treatments for conditions such as autism, cognitive delays, hearing loss and recovery following injury and neurodegeneration.
- The Developmental, Degenerative, and Regenerative Neuroscience group currently has seven faculty members and is part of a large number of faculty in the Department of Neurological Sciences.
- Each faculty member has an active, independently funded research program, but they also collaborate on specific projects and utilize shared space and equipment.
- The laboratories share a focus on utilizing cell biology and molecular approaches as well as stem cells in investigating the genetic and environmental causes of developmental disabilities and strategies for neural regeneration.
- Ph.D. graduate students and post-doctoral fellows receive 4-5 years of individual training and mentoring in Developmental, Degenerative, and Regenerative Neuroscience laboratories.
- Neurology Residents have an opportunity to perform basic translational research.
- Members of the Department participate in teaching in courses for students in research and clinical programs across UNMC Colleges.
- Faculty members have developed a new course in Molecular and Cellular Neuroscience for Ph.D. students in biomedical research programs.
- Dr. Smith directs the MD/PhD program for UNMC which trains physician/scientists for clinical practice and biomedical research.
Our research programs focus on understanding the genetic and environmental causes of developmental disabilities and how they affect the brain and sensory systems, including:
- Genetic causes of neurodevelopmental disorders (Autism Spectrum Disorders, Fragile X syndrome, Rett syndrome (Dunaevsky, Ragunathan).
- Environmental contributors to neurodevelopmental disorders such as maternal infection during pregnancy (Dunaevsky) and Fetal Alcohol Spectrum Disorders (Ragunathan).
- Regeneration of sensory cells in the ear to restore hearing loss (Huh).
- Genetic influences on hearing loss and reading and language disorders (Smith).
- Bioengineering strategies for tissue regeneration (Li).
- All of our faculty members have been awarded outside funds for their research, including state, national foundation, and federal funds.
- DONS is the home institution for a Center for Biomedical Research Excellence, an NIH-funded program now in its 15th year of funding. The Center supports research in hearing loss, vision loss, and brain development and includes researchers at UNMC, Creighton University, and Boys Town National Research Hospital. The program also supports research core facilities and a mentoring program for new researchers to advance their careers.
