Query: How inertial lift affects the dynamics of a microswimmer in Poiseuille
  flow   We analyze the dynamics of a microswimmer in pressure-driven Poiseuille flow,
where fluid inertia is small but non-negligible. Using perturbation theory and
the reciprocal theorem, we show that in addition to the classical inertial lift
of passive particles, the active nature generates a `swimming lift', which we
evaluate for neutral and pusher/puller-type swimmers. Accounting for fluid
inertia engenders a rich spectrum of novel complex dynamics including bistable
states, where tumbling coexists with stable centerline swimming or swinging.
The dynamics is sensitive to the swimmer's hydrodynamic signature and goes well
beyond the findings at vanishing fluid inertia. Our work will have non-trivial
implications on the transport and dispersion of active suspensions in
microchannels.
