My research focuses on developing continuum and individual-based computational models to better understand and improve food safety through a more fundamental understanding of how pathogens interact with food. The continuum models are developed in COMSOL, commercial finite element software, to simulate the environment, and the individual-based models use open source code to simulate the bacteria. Bacteria are everywhere in our world and on our food. Therefore, through a greater understanding of how attachment/detachment, growth/death, and movement occur, I can develop mitigation and removal strategies to improve food safety. I study such problems as infiltration into fresh produce from hydrocooling and pathogen growth on fresh produce. My models use realistic geometries of food acquired from such imaging techniques as MRI and µCT.
