JIFSAN , a joint program of the University of Maryland and the U.S. FDA , is seeking a full-time Post-Doctoral Associate position within the FDA Center for Food Safety and Applied Nutrition ( CFSAN ).

The incumbent will participate in applied regulatory research for targeted and non-targeted mass spectrometric methods for the identification economic adulteration of food products such as honey and fruit juices. Incumbent will collaboratively identify markers, develop databases or libraries, and validate a mass spectrometric method to identify biomarkers and metabolites formed in the production of syrup matrices in comparison to pure honey.

Additionally, research will be expanded into characterizing and identifying marker ions that can be used to discriminate the substitution of fruit juices, such as lime and lemon juice. Also, duties will include monitoring instrument performance metrics in lab quality assurance and control programs, as well as providing routine instrument maintenance and calibration service. Completed research studies are expected to be published in peer-reviewed journals.

Specific Aims:

1. Develop non-targeted mass spectrometric methods for the identification of biomarkers and metabolites in syrups utilized for the economic adulteration of honey.

2. Build upon existing Isotope Ratio Mass Spectrometry ( IRMS ) methods for the identification of adulterated honey products.

3. Develop and construct, as necessary, targeted spectral libraries to extend the identifications to other MS platforms.

5. Develop methods in the characterization of fruit juices for economic adulteration and substitution.

4. Present data at scientific meetings and publish research findings in peer-reviewed journals.

Responsibilities:

Develop non-targeted and targeted methods utilizing high-resolution mass spectrometry ( HRMS ) for bio-marker ions found in a variety of syrups. (30%).

Utilize the HRMS marker ions populated in spectral libraries as well as IRMS honey sample surveys to identify instances of adulteration in import and domestic honey samples. (30%).

Develop validate a method for the discrimination of adulterated and/or substituted fruit juices. (30%)

Present data at meetings and publish research findings in peer-reviewed journals (10%)
