OverviewAI-generated summary

A.G. Buchan's research focuses on the application of radiation for disinfection and the development of computational modeling techniques. Buchan has investigated the inactivation rates of airborne human coronaviruses, including SARS-CoV-2 and Coronavirus OC43, using low doses of 222 nm far-UVC radiation. This work includes developing and validating high-fidelity coupled radiation-computational fluid dynamics codes to improve estimates of susceptibility. Additionally, Buchan has contributed to the field of nuclear engineering through the development of reduced-order models for complex equations, such as the multigroup neutron diffusion equation and the Boltzmann transport equation. This includes work on nonlinear interpolation methods for control-rod movement and adaptive models for space-angle discretization. Buchan also developed a tool for gamma ray dose rate calculation and mapping relevant to marine nuclear emergency response scenarios. Buchan holds a h-index of 13 with 38 publications and 443 citations.
