Doherty is a theorist whose early work established much of the modern framework for continuous quantum measurement and quantum feedback control, and who now works across quantum information theory, error correction and the characterisation of quantum devices. For a sensing candidate the relevant body of work is the measurement/feedback theory: conditional evolution under continuous observation, the role of back-action, and the design of feedback protocols that stabilise a quantum system while extracting information from it. Positioned against the established body of NV-ensemble quantum sensing work — DEER, nanoscale NMR and T1 relaxometry protocols operating at pT/sqrt(Hz) field sensitivity — the continuous-measurement formalism he helped build is what one uses to ask whether a pT/sqrt(Hz) NV ensemble measurement is saturating its quantum Fisher information bound or merely its shot-noise bound. Borderline inclusion — the current group output is largely quantum computing theory rather than sensing — but retained under the inclusive rubric given the measurement-theory pedigree.
