Join the HJF Team!

HJF is seeking a Postdoctoral Fellow to support the Clinical Neuroscience of Psychopathology (CNP) Lab (PI: Joshua Gray, PhD) in the Department of Medical and Clinical Psychology at Uniformed Services University in Bethesda, MD. The Fellow will work on studies that aim to: 1) elucidate the genetic and neurobiological basis of impulsivity, personality, addiction, and other psychopathology; 2) investigate organizational factors that impact well-being, readiness, and turnover in service members exhibiting harmful alcohol use. The Fellow will work with open datasets (e.g., Adolescent Brain Cognitive Development [ABCD] study, UK Biobank) and will collaborate with representatives from the Defense Health Agency (DHA).

The Fellow will contribute to a multisite randomized clinical trial of repetitive transcranial magnetic stimulation (rTMS) for depression in veterans and active duty service members with depression and a history of mild traumatic brain injury. Specifically, in collaboration with Center for Neuroscience and Regenerative Medicine (CNRM), the CNP is planning a sub-study utilizing technology from the private industry to passively acquire smartphone data (e.g., keyboard performance, scroll speed, activity) to track continuous fluctuations in mood and cognition following sessions of rTMS. This technology enables ecologically valid, passive assessment of mood and cognition to track clinical outcomes and inform providers when increased care is required.

Qualified applicants will have a PhD in clinical psychology, neuroscience, bioinformatics, or a related field, multiple peer-reviewed publications, experience with analysis of large datasets of psychological, neuroimaging, and genetics data, and proficiency in statistics, machine learning, and software such as R, Python, AFNI, FreeSurfer, and Unix. The candidate will work directly with the CNP Lab’s PI and will be responsible for data analysis, collection, presentation, and publication of findings. The Fellow will have funding to attend trainings and conferences and opportunity to propose independent studies extending beyond those described. The CNP Lab maintains active collaborations with leading researchers from NIH, CNRM, and other major universities. The position is 2-3 years and includes a competitive salary package.


  1. Conducts data cleaning and advanced statistical analysis of genetic, neuroimaging, and psychological data.
  2. Leads manuscript writing, publication, and oral presentation of research findings.
  3. Coordinates research studies using large open datasets and involving new data collection.
  4. Assists with the preparation of technical reports, summaries, study protocols, and preparing IRB submissions.
  5. Interfaces with research collaborators, graduate students, and research assistants.
  6. Maintains compliance with established laboratory safety and other procedures.

Required Knowledge, Skills, and Abilities: Experience/skills in data management, statistics, communicating effectively both orally and in writing, and working in a team setting.

Preferred Knowledge, Skills, and Abilities: Candidates with intermediate to advanced skills in data management, statistics, and neuroimaging/genetics software (R, Python, AFNI, FreeSufer, Unix) are strongly encouraged to apply. Furthermore, applicants with knowledge of machine learning approaches (e.g., elastic net regression, random forest, XGBoost) are of high interest.

Minimum Education/Training Requirements:  PhD degree from an accredited college in clinical psychology, neuroscience, bioinformatics, or a related field.

Minimum Experience: Significant laboratory experience, prior publications (preferably some first author), understanding of statistics, and prior experience writing syntax.

Physical Capabilities:  Requires long periods of sitting and standing

Work Environment:  Research laboratory environment
