Overview

Chadi G. Abdallah is affiliated with Baylor College of Medicine in the United States. Their research primarily spans the fields of neuroscience, medicine, and psychology, with significant contributions to subfields such as cognitive neuroscience, clinical psychology, pharmacology, experimental and cognitive psychology, and biological psychiatry.

The scientist's work centers on several important topics, including functional brain connectivity studies, treatment of major depression, mental health research, tryptophan and brain disorders, traumatic brain injury research, posttraumatic stress disorder research, and neuroscience and neuropharmacology research.

Abdallah has published multiple research articles, with some of the recent papers reflecting investigations into ketamine's effects and brain abnormalities associated with psychiatric conditions. Notable publications include:

"Modulation of the antidepressant effects of ketamine by the mTORC1 inhibitor rapamycin," 2020, Neuropsychopharmacology
"Cortical volume abnormalities in posttraumatic stress disorder: an ENIGMA-psychiatric genomics consortium PTSD workgroup mega-analysis," 2020, Molecular Psychiatry
"Dose-related effects of ketamine for antidepressant-resistant symptoms of posttraumatic stress disorder in veterans and active duty military: a double-blind, randomized, placebo-controlled multi-center clinical trial," 2022, Neuropsychopharmacology
"International pooled patient-level meta-analysis of ketamine infusion for depression: In search of clinical moderators," 2022, Molecular Psychiatry
"Assessment of brain age in posttraumatic stress disorder: Findings from the ENIGMA PTSD and brain age working groups," 2021, Brain and Behavior

The scholar frequently publishes in venues such as bioRxiv (Cold Spring Harbor Laboratory), Neuropsychopharmacology, Biological Psychiatry, Chronic Stress, and Biological Psychiatry Cognitive Neuroscience and Neuroimaging.

Key collaborators who often co-author work with Abdallah include John H. Krystal, Christopher L. Averill, Lynnette A. Averill, Saskia B.J. Koch, and Miranda Olff.
