Yes. All costs which are directly related to the execution of the project can be claimed, i.e. the personal costs/salary of the Principal Investigator can also be claimed, but only to the extent of the actual working hours she/he was committed to the execution of the project. Those costs will be reimbursed to 100%. The level of the Principal Investigator's salary together with the overall personal cost calculation of the project must however be in line with the host institution's own accounting principles.
