Profile Summary

Brandon D. Gallas provides mathematical, statistical, and modeling expertise to the evaluation of medical imaging devices at the FDA (https://www.fda.gov/medical-devices/medical-device-regulatory-science-research-programs-conducted-osel/digital-pathology-program-research-digital-pathology-medical-devices). His main areas of research are image quality, computer-aided diagnosis, imaging physics, and the design, execution, and statistical analysis of reader studies (https://github.com/DIDSR/iMRMC/releases, https://cran.r-project.org/web/packages/iMRMC/index.html, https://www.fda.gov/medical-devices/science-and-research-medical-devices/imrmc-software-do-multi-reader-multi-case-statistical-analysis-reader-studies). Recently, he has been investigating pathologist performance and agreement using whole slide imaging devices and the microscope (https://didsr.github.io/HTT.home/). These studies are enabled by an evaluation environment that registers the digital images to the glass slides (https://github.com/DIDSR/eeDAP/releases). Dr. Gallas also participates in the Pathology Innovation Collaborative Community (https://www.pathologyinnovationcc.org/), a regulatory science initiative to harmonize and standardize digital pathology processes to speed up innovation to patients.
