Under the ERC 2018 Proof of Concept (PoC) Grant, is it preferable to have a project of 12 or of 18 months?

Where an ERC PoC proposal has initially indicated a duration of 12 months, during grant preparation, PIs are usually advised to go for a longer timespan (18 months), just in order to cope with eventual delays and always finish the project in an acceptable period of time, although the final decision will be with the Principal Investigator (PI). The reason is that under H2020, extensions of duration to PoC projects are typically not granted once the project has started.

According to the conditions applied to the ERC frontier research Grants 2018 (StG / CoG / AdG / SyG), can a Principal Investigator (PI) cover this role in more than one proposal at the same time?

According to the conditions applied to the ERC frontier research Grants 2018, there are three main restrictions to be considered for PIs in this regard:
- A PI may submit proposals to different ERC frontier research Grant calls made under the same Work Programme, but only the first eligible proposal will be evaluated.

According to the conditions of the ERC Starting Grant 2018 call, what are eligible career breaks that are considered for the extension of the eligibility window?

According to the conditions of the ERC Starting Grant 2018 call, eligible career breaks that can be considered for the extension of the eligibility window are:
Maternity or paternity leave,
Long-term illness (over ninety days for the Principal Investigator or a close family member),
Clinical training,
National service.
All these circumstances need to be properly documented. Please find below examples of such documents:

According to the conditions of the ERC Starting Grant 2018 call, what will happen if the PhD certificate is not submitted together with the proposal?

According to the conditions of the ERC Starting Grant 2018 call, as long as no PhD document or equivalent is uploaded in the Participant Portal Submission Service, it will not be possible to validate/submit the proposal. A warning message will inform the applicant of the missing document. If another document is uploaded instead and the PhD certificate is missing the ERCEA may contact the PI and ask for a clarification and the missing document.
For more information, see section 'Eligibility criteria' of the ERC Work Programme 2018 .

According to the conditions of the ERC Starting Grant 2018 call (ERC-2018-STG), which is the date to be considered for the granting of the PhD (or equivalent degree)?

According to the conditions of the ERC Starting Grant 2018 call (ERC-2018-STG), the reference date for calculating the eligibility period should be the date of the actual award according to the national rules in the country where the degree was awarded.
In the case of applicants having been awarded several PhDs, the reference date is the award date of the first PhD.
For more information, see section 'Eligibility criteria' of the ERC Work Programme 2018 .

According to the conditions of the ERC Starting Grant 2018 (ERC-2018-STG) call, is a Medical Doctor degree equivalent to a PhD degree?

According to the conditions of the ERC Starting Grant 2018 (ERC-2018-STG) call, for medical doctors (or applicants holding a degree in medicine), a medical doctor degree will not be accepted by itself as equivalent to a PhD award. To be considered an eligible Principal Investigator, medical doctors (or applicants holding a degree in medicine) need to provide the certificates of both a medical doctor degree and a PhD or proof of an appointment that requires doctoral equivalency (e.g. post-doctoral fellowship, professorship appointment).

According to the conditions of the ERC Starting Grant 2018 (ERC-2018-STG) call, for medical doctors who hold both a medical doctor degree and a PhD, which degree will be taken into consideration for the calculation of the eligibility window?

According to the conditions of the ERC Starting Grant 2018 call, for medical doctors who have been awarded both a medical doctor degree and a PhD, the date of the earliest degree that makes the applicant eligible takes precedence in the calculation of the eligibility time-window (2-7 years after the date of award of the PhD or 4-9 years past the medical doctor degree completion for Starters).
For more information please consult the ERC policy on PhD and equivalent doctoral degrees in the ERC Work Programme 2018 – Annex 2.

If a Principal Investigator only has a Master Degree and no PhD, can they apply to the ERC Starting Grant 2018 (ERC-2018-STG) call?

No, according to the conditions of the ERC Starting Grant 2018 call, the Principal Investigator must have been awarded a PhD or equivalent doctoral degree to be eligible. First-professional degrees will not be considered in themselves as PhD-equivalent, even if recipients carry the title "Doctor".
For more information please consult the ERC policy on PhD and equivalent doctoral degrees in the ERC Work Programme 2018, Annex 2.

According to the conditions applied to the ERC Grants 2018, can a researcher participate as PI in more than one ERC frontier research proposal at the same time? Is it possible to receive funding for more than one participation in such case?

According to the conditions applied to the ERC frontier research Grants 2018 (Starting, Consolidator, Advanced, Synergy), there are three main restrictions to be considered for Principal Investigators in this regard:
 
A Principal Investigator may submit proposals to different ERC frontier research grant calls published under the same Work Programme, but only the first eligible proposal will be evaluated.

Must the Principal Investigator applying for an ERC Starting Grant 2018 (ERC-2018-STG) choose the appropriate ERC peer review evaluation panel for their proposal?

According to the conditions of the ERC Starting Grant 2018 call, the applicant must choose a primary evaluation panel and may also indicate a secondary evaluation panel. They should indicate when they believe that their proposal is of a cross-panel or cross-domain nature.
In most cases the proposal will be evaluated by the primary panel indicated by the applicant. However, if the scope of a proposal does not correspond to the expertise of the primary panel, the proposal can be reallocated to another panel, if the panel chairs of the original and the new panel agree to do so.
