• Manage ongoing data collection: monitor study and data-collection workflows, troubleshoot operational issues, respond to participant emails, and coordinate participant payments.
• Serve as a reliable point of contact for external partners and agencies, track deliverables and follow through on open items.
• Support data organization, quality checks, and basic analysis using Google Sheets and Python.
• Help prepare research reports and manuscripts by coordinating review steps, proofreading, and checking materials for accuracy and consistency.

What you will need

• Experience coordinating research with human participants, including study logistics and participant-facing communication.
• Strong project- or study-management skills: you can keep multiple workstreams organized, anticipate dependencies, track details, and follow through reliably.
• Clear, professional written and verbal communication skills, including comfort coordinating with researchers, participants, and external partners.
• Meticulous attention to detail and excellent time management.
• Strong proficiency with Qualtrics and/or JavaScript, including building and maintaining surveys or assessments.
• Proficiency with Excel or Google Sheets, including formulas and pivot tables.
• Working proficiency with Python for data organization, quality checks, or analysis.

Exceptional candidates will have

• Experience managing multiple studies or research projects at once, especially studies involving external vendors or testing providers.
