What We Offer and Who is Eligible

JHBC consults with JHSPH graduate students on research for their thesis, dissertation or other individual research projects on which the student is the lead author.

These consultations are provided through FREE walk-in clinics. NOTE: JHBC does not consult on coursework, MPH capstone projects, nor do its services replace statistical oversight by the student’s academic committee or research mentor.

Consultations are available on study design, sample size and power calculations, organization of data for statistical analysis, statistical analysis approach, and assistance with implementing analyses in statistical software (STATA, SAS, R).

Time of Clinics and Sign-up

The virtual walk-in clinics will be conducted via MS Teams from 10:30 to noon on Fridays, in place of the regular walk-in clinics. (Questions about MS Teams? Visit the Microsoft Teams Training Site.)

Students can fill out the sign-in form online at This link is only available on Fridays, 9:30-11:30am. The biostatistician experts running the clinic on that Friday will send a MS Team note to confirm availability and initiate a MS Teams call. As usual, we plan to provide an approximately 20- to 30-minute consultation to each student on a first-come, first-served basis.

If you are not contacted, it means there is no more available spots and you can try to sign-up on the following Friday. Please, do not send any additional emails to the consultants outside the clinic time.

How to Make Efficient Use of the Clinic

Consultation time is limited and the student should come prepared to facilitate the biostatistician’s understanding of their research project. This includes a description of the research hypotheses, the population to be sampled or included in existing source data, outcomes measured and to be analyzed, and their question of interest. If the question is related to sample size/power, clinically significant effect sizes for the primary outcome based on literature or previous pilot studies, and levels of precision or power required will be needed. These consultations also expect the student to have a basic understanding of statistics.
