Coupling of damped and growing modes in unstable shear flow
Published in Physics of Plasmas, 2017
Analytic calculations show that stable (damped) inviscid modes are nonlinear driven by unstable modes in an unstratified shear flow.

Role of stable modes in driven shear-flow turbulence
Published in Physics of Plasmas, 2018
Nonlinear excitation of stable modes are shown from simulations of shear-flow turbulence; inclusion of stable modes in reduced models explored.

Role of stable eigenmodes in shear-flow instability saturation and turbulence
Published in , 2020
My Ph.D. thesis. Chapters 2-4 are essentially identical to my first three papers. The introduction and conclusions help tie everything together, though. Also, the appendices in Chapter 4 describe a neat, unpublished calculation.

The impact of magnetic fields on momentum transport and saturation of shear-flow instability by stable modes
Published in Physics of Plasmas, 2021
Flow-aligned magnetic fields are shown to reduce stable mode activity, providing an interpretation for trends in turbulent transport.
