Virtual Drop-In Sessions

Free consultations on study design and statistical analysis are available at our Virtual Research Help Drop-in Sessions. The format is a 30-minute Zoom call with one of our statisticians.

These sessions are available to anyone affiliated with Tufts CTSI – including students, research fellows, and residents – and are especially helpful for those needing guidance in carrying out their own analyses.

Currently, Drop-In sessions are offered twice per week. Registration is required. Please view the calendar and sign up here.

Who is eligible?

Some pre-award BERD Center services are offered at no cost to investigators at institutions affiliated with Tufts CTSI; other services (post-award) are offered for a fee and are available to anyone (the rate may vary).

Drop-in Sessions are open to anyone at an institution affiliated with Tufts CTSI, especially faculty members, fellows, residents, and graduate students.

Student projects are not eligible for these free services, but students engaged in faculty-led projects may receive free consultations if the PI is a faculty member at a Tufts CTSI-affiliated organization and the faculty member participates in the consultation.


To contact us, please submit a service request.
