Vilas Menon, PhD
Dr. Menon obtained his PhD in Applied Mathematics from Northwestern University, where he studied signal integration and information processing in neurons. Prior to joining Columbia, he spent several years as a staff scientist at the Allen Institute for Brain Science in Seattle, WA, and as a Fellow at the Howard Hughes Medical Institute’s Janelia Research Campus, developing new analytical methods for large-scale single-cell and bulk molecular data analysis. At Columbia, his lab applies state-of-the-art computational and experimental methods to generate and analyze large-scale molecular data in the context of neurological disease. In particular, his group investigates signatures of differential vulnerability and resistance at both the cell type and individual level in neurodegenerative diseases (including Alzheimer’s and Parkinson’s) and neuroimmune diseases (such as Multiple Sclerosis).

- Selective vulnerability of cell types in neurological disease – It has long been known that disease-specific pathologies do not have uniform effects on all cell types in the brain. A major arm of our research is to systematically identify and investigate the differential impacts of pathology on cell types in the human brain. To achieve this, we combine single-cell and bulk methods with spatially-resolved molecular methods on post-mortem human brain tissue to develop integrative models evaluating cell type-specific dysregulation. We apply these approaches to multiple diseases, with a number of clinical and experimental collaborators at Columbia and beyond.
- Individual resilience to pathology – In diseases such as Alzheimer’s, Parkinson’s, and Multiple Sclerosis, certain individuals exhibit minimal cognitive and/or motor symptoms despite having substantial disease-specific pathology in their brains (as identified post-mortem). This suggests that these rare individuals may have compensatory mechanisms allowing them to maintain regular function even in the presence of deleterious perturbations. Here, we apply a suite of computational and experimental profiling methods to characterize resilience-associated signatures, which are distinct from risk factors for these diseases.
- Reproducibility in studies within and across diseases – The explosion of large-scale molecular profiling methods for genome-wide single-cell and spatial data generation has led to a wealth of published studies investigating post-mortem human brain tissue in a variety of diseases. A major area of our research is evaluating and prioritizing cell type-specific observations in various neurological diseases based on findings from multiple studies. This type of prioritization is key to identifying potentially robust targets for disease-specific therapeutics.
