Theoretical command
Probe command of colloidal stability, PEGylation and opsonisation, EPR effect limits, and biodistribution kinetics; ask them to defend a carrier choice (LNP versus polymeric versus liposomal) for a given payload.
Evidence to listen for
- Explains the underlying theory at the level the role demands, and can go a layer deeper when pushed
- Knows which results are established and which are contested
- Distinguishes their own contribution from the field's
- Comfortable saying where the theory runs out
Five-point scoring guide
Recites terminology without understanding; cannot go one layer deeper.
Surface familiarity; conflates established results with speculation.
Solid grasp of the core theory; thin at the frontier.
Strong command; separates settled results from open questions.
Explains zeta potential, PDI and endosomal escape mechanistically, and names conditions where their preferred carrier fails or clears too fast.
