Associate Research Scientist
Biography
Amir Valizadeh earned his MD from Tehran University of Medical Sciences in 2019. His research integrates computational biology, machine learning, and clinical expertise, with a focus on multi-omics integration, epigenomic profiling, and biomarker discovery in psychiatry and immunology. Currently, as a Postdoctoral Associate at Yale School of Medicine and VA Connecticut Healthcare System, he is exploring transcriptomic alterations in SIV/HIV infection and leveraging AI for precision diagnostics, such as DNA methylation-based prediction of ketamine response in PTSD.
