The Gregory lab is involved in several lab-based and collaborative research projects that focus on identifying the genomic, genetic, and epigenetic underpinnings of complex neurological diseases.

Brain tumors:

As early adopters of single cell and spatial expression profiling approaches, the Gregory lab and the Molecular Genomics Core is applying early access in situ  sequencing technologies to identify the signatures of brain tumor development and progression. These technologies have the capacity to profile RNA expression at true single cell level resolution and in doing so unravel the heterogeneity of the tumor microenvironment using panels of canonical markers of cell type/state to elucidate the cell-cell and cell-neighborhood interaction analyses.

We are combining single nuclei/cell modalities and spatial RNA/protein approaches with traditional whole genome and exome sequencing, epigenetic profiling, and bulk RNA-Seq transcriptome methods to underpin the next phase of brain tumor research. Together with basic and clinical scientists across Duke, the Gregory lab is a founding member of the new Brain Tumor Omics Program developed in conjunction with Dr. David Ashley, Director of the Preston Robert Tisch Brain Tumor Center.

Multiple Sclerosis:

Dr. Gregory is Principal Investigator of the MURDOCK_MS study which includes ~1,000 multiple sclerosis patients. This cohort has been used to identify multi-omic biomarkers to facilitate reclassification of the disease (Cote et al 2019, Multiple Sclerosis and Related Disorders), and to assess MS progression using ultra-high sensitivity protein assays in a cohort of primary progressive MS patients (Profiling serum neurofilament light chain and glial fibrillary acidic protein in primary progressive multiple sclerosis).

SGregory Remyellination Research

The Gregory lab is also exploring the efficacy of a novel hydroxyl-cholesterol (HC) treatment of remyelination in MS. Together with Drs. Eric Benner (Duke, Pediatrics), Mari Shinohara (Duke, Immunology), and Glenn Matsushima (UNC-CH, Microbiology and Immunology), this transformative study is trying to understand the cellular mechanisms in which HCs trigger the differentiation of neural progenitor cells into oligodendrocyte progenitor cells (OPCs) and/or OPCs into oligodendrocytes, the cell that is critical for triggering remyelination in MS. Early data provides exciting evidence of remyelination in the context of a demyelinating pre-clinical model of MS.


SGregory Autism Research Graphic

Recent CDC estimates suggest that autism affects more than one in 68 children in the US. The Gregory lab is using genetic and epigenetic approaches to understand the mechanisms driving core deficits associated with autism at developmental and therapeutic levels via oxytocin treatment in pre-clinical and human trials with Dr. Lin Sikich. In collaboration with Dr. Sheryl Moy (UNC, Psychiatry) and Dr. Yong-Hui Jiang (Yale, Medical genetics), Dr. Gregory's lab is exploring the mechanisms of oxytocin response in a clinical trial of autistic children, to refine the epigenetic regulation of the oxytocin receptor (OXTR), and to understand the molecular underpinnings of oxytocin effects and societal interaction in an animal model of autism. The findings will provide valuable insight into the mode of action of oxytocin response in specific regions of the brain that will be applicable to clinical trials of oxytocin treatment in numerous psychosocial phenotypes, including autism.

Alzheimer’s Disease:

Gregory Lab AD Research

The Gregory lab, together with collaborators Drs. Jerry Wang (Department of Pathology) and Dianne Cruz (Department of Psychiatry), is using spatial transcriptomics to characterize the RNA expression changes that occur with the progression of Alzheimer’s disease. These data are correlated with the microarchitecture of the brain and disease pathology to understand the molecular changes associated with the disease. We are also pairing these data with a long-read sequence platform to explore RNA splicing in a spatial context to determine the effects of AD pathology in isoform production.


Dr. Gregory is a tenured Professor and Director of the Brain Tumor Omics Program (BTOP) in the Duke Department of Neurosurgery, the Vice Chair of Research in the Department of Neurology, and Director of the Molecular Genomics Core at the Duke Molecular Physiology Institute (DMPI). As a neurogenomicist, Dr. Gregory applies his experience gained from leading the sequencing of chromosome 1 for the Human Genome Project to elucidating the mechanisms underlying multi-factorial diseases using genetic, genomic, and epigenetic approaches. Dr. Gregory’s primary areas of research involve understanding the molecular processes associated with disease development and progression in brain tumors and Alzheimer’s disease, novel drug induced white matter injury repair in multiple sclerosis, and social and behavioral response to oxytocin treatment animal models of autism. He is broadly regarded across Duke as a leader in the development of novel single cell and spatial molecular technologies towards understanding the pathogenic mechanisms of disease development. Dr. Gregory is also the Section Chair of Genomics and Epigenetics at the DMPI and Director of the Duke Center of Autoimmunity and MS in the Department of Neurology.
