U.S. Department of the Air Force Summer Faculty Fellowship Program tenure is for a continuous period. Consequently, no breaks  for leave, such as vacation, teaching engagements, or conferences are  permitted. If the lab advisor deems it necessary for the participant to  attend a conference because it is related to the summer fellowship, the  advisor must write to afsffp.pmo@sysplus.com before  the leave is to take place, indicating that the leave is necessary and  has been approved by the lab. All such requests will be forwarded to the  AFOSR for further approval. U.S. Air Force Research Lab Summer Faculty Fellowship Program  participants should not make  arrangements to leave the lab before official approval has been granted  and has been communicated by Systems Plus. If the leave is approved,  participants will not be compensated for their stipend, temporary moving  allowance, or travel expenses during their time away from the lab.
