POSITION SPECIFICS

The Kovac Laboratory in the Department of Food Science at The Pennsylvania State University seeks a highly motivated Postdoctoral Scholar to lead research on the prevention of cereulide contamination in infant formula and fermentation-derived food ingredients. The successful candidate will work on a multidisciplinary project focused on improving detection of cereulide-producing Bacillus cereus , understanding factors driving cereulide formation in industrial fermentation systems, and contributing to the development of quantitative microbial risk assessment models to support industry and regulatory decision-making.

The Postdoctoral Scholar will play a central role in experimental design, laboratory research, data analysis, project coordination, publication development, mentoring trainees, and communication with collaborators.

Major Responsibilities

Research and Laboratory Activities

Lead and conduct independent research aligned with project objectives.

Perform microbiological analyses involving isolation, cultivation, enumeration, characterization, and preservation of Bacillus cereus group isolates.

Develop, validate, and optimize culture-based and molecular detection methods for emetic B. cereus .

Conduct experiments evaluating microbial growth, toxin production, and survival under conditions relevant to infant formula and industrial fermentation systems.

Conduct whole genome sequencing and sequence data analyses.

Design and execute challenge studies and storage studies involving foodborne pathogens and spoilage microorganisms.

Ensure compliance with laboratory safety protocols, biosafety procedures, and quality assurance practices.
