Microbiologist (University of Massachusetts Amherst) who originated the
conductive-pili ("e-pili") model of *Geobacter* nanowires — the proposal, from
Reguera et al. (*Nature*, 2005), that PilA-based type-IV pili carry electrons
over long range for extracellular electron transfer. Matters to this vault as
one pole of an active scientific-priority dispute: the model he founded was
later overturned structurally by his former lineage-member Nikhil Malvankar, and
Lovley continued to defend e-pili in print as of 2022, making this a clean case
of an origin-model author outlasting his own model in the literature.
