PUBLICATIONS (Last updated 12.2021)
Since arriving at OSU in 2016, I have published 24 papers (as of Dec 2021) despite career interruptions in 2018 and due to the Burt Hall fire in that virtually shut down analytical capabilities at CEOAS in 2019, with continued sporadic interruptions through 2021.
