How to get an appointment?

Please register by use of our online form

To register, you need to identify yourself as eligible by using your official e-mail account (,,

Charité doctoral students can simply go to the Charité matriculation office with their doctoral registration and matriculate as a doctoral student. They will then be provided with a Charité email account.

What next?

  • your details will be recorded to our internal database for documentation and administrative purposes.
  • you will be assigned a consultant depending on your subject as well as on your requests made concerning consultant and location
  • your consultant will then contact you shortly, usually within 5 working days, and arrange for an appointment.

How do I prepare for the consultation?

  • You should be able to give a short and concise description of your project. Avoid terminology.
  • You should be able to formulate the scientific objectives of your project clearly as yes/no questions.
  • Have relevant literature with you (study protocol, literature sources, etc.).

Do I need consultation?

  • We recommend a biometric consultation for all medical research projects, if possible already during the planning phase. In particular, we recommend biometric consulting for doctoral theses.
  • Studies that must be approved by either Charité's Ethics Committee or LAGeSo Ethics Committee (AMG studies, MPG studies) require the mandatory participation of a biometrician. Our staff have extensive experience both in drafting ethics proposals as well as statistical members of various ethics committees.

Please note: Biometric consulting does not mean taking responsibility for the entire project biometrics. Taking responsibility needs to be covered by a cooperation agreement with corresponding counter-financing.

Confirmation by an accredited statistician for "doctorate by publication"

If you are planning a doctoral project that includes a relevant statistical part, and if you wish to do your doctorate by means of a monograph, you must submit a certificate from a statistician accredited to the Doctoral Commission along with your application for the opening of the doctoral procedure, stating that the type and scope of statistical processing is sufficient (Section 8 (2)a PO 2017).

The scientific staff of the Institute of Biometry and Clinical Epidemiology are recognized as accredited statisticians by the doctorial office. The consultation service of the Institute's Biometrics Service Unit is explicitly recommended.

  • If you make use of the free statistical consultation service of the Service Unit during your research work, the Institute of Biometry Clinical Epidemiology will issue a corresponding confirmation upon request. Please make an appointment online in good time, as the availability of appointments depends on the respective demand.
  • Ideally, you should arrange a consultation at the beginning of your doctoral project, i.e. in the planning phase, and a follow-up appointment in the implementation or evaluation phase. At the first consultation appointment please bring the copy of your doctoral agreement confirmed by the doctoral office.
  • The content of any consultation will be documented. At the end of the consultation, the consultant of the Service Unit Biometry will issue a confirmation of the accompanying statistical consultation. Please enclose this confirmation with your documents when you apply for the opening of your doctoral project.
  • If you are planning a doctoral project using a monograph that does not include a relevant statistical part (for example, in a purely humanities-based project), please indicate this in the appropriate section of the doctoral agreement. You will be exempted from the obligation to submit a confirmation in accordance with Section 8 (2)a PO 2017.
  • If you wish to do your doctorate by submitting publications (publication doctorate), you are generally not required to submit the certificate in accordance with Section 8 (2)a PO 2017. Statistical advice is nevertheless recommended.
