Shalaila S. Haas, Ph.D., is a cognitive neuroscientist with a specialization in implementing advanced machine learning techniques to identify links between behavioral patterns and neural signatures. Her research aims to unravel the underlying mechanisms that drive the heterogeneity in clinical presentation, course, and treatment response in neuropsychiatric disorders at the individual level. She has adopted a precision medicine approach, aiming to identify mechanisms of accelerated aging and modifiable environmental risk factors that contribute to this heterogeneity in individuals with mental illness and aging populations. This innovative research holds immense potential to advance our comprehension of these complex disorders, offering opportunities for improving diagnostic and therapeutic strategies to alleviate suffering by preventing the onset or by improving the illness course across neuropsychiatric disorders.
