Pertemuan Ilmiah Tahunan (PIT) 2025 PERMI: Food Safety and Food Pathogen Detection
Talk on strategic issues in food safety, emergent microbial threats, and rapid detection technologies at PIT PERMI 2025.
About Me
Welcome! I am a food safety researcher working at the intersection of wet-lab molecular microbiology and computational risk modeling. My work focuses on tracking and controlling foodborne pathogensβfrom investigating biofilm resistance and fermentation ecology to developing rapid diagnostic assays and Quantitative Microbial Risk Assessment (QMRA) models. I am passionate about open science, reproducible data workflows in R, and advancing global food safety standards.

π Research Program
My research combines wet-lab molecular diagnostics with computational modeling to safeguard food systems across four core pillars:
- 𧬠Molecular Detection Designing rapid PMA-qPCR and isothermal (MIRA) assays to selectively quantify viable pathogens in complex food matrices.
- π¦ Fermentation Safety Decoding microbial ecology in traditional fermented products to inhibit pathogen growth and toxin formation.
- π‘οΈ Biofilm Control Assessing non-thermal physical and chemical interventions against persistent pathogenic biofilms on food-contact surfaces.
- π Quantitative Risk & Meta-Analysis Building QMRA models, predictive growth kinetics, and reproducible R workflows for evidence synthesis.
