The Physical Internet Doctoral Colloquium provides PhD candidates with the opportunity to present and discuss their research with fellow PhD candidates and established researchers. One of the key elements of the seminar will be to discuss positioning of the PhD project in well-known and established lines of research and linking it in a founded way to the physical internet. Participation in the colloquium is by invitation. PhD candidates are asked to submit a research proposal or a working paper for review, along with a letter of recommendation. A limited number of grants will be made available to excellent PhD candidates to cover travel and hotel costs.
