Join a NIH-funded research program about dietary supplements. This research program supports the Dietary Supplement Ingredient Database (DSID; (, a database for information on analytically verified dietary supplement content. The DSID website provides online calculators converting labeled levels into analytically derived estimates of ingredients in dietary supplement products sold in the US. Funded by the National Institutes of Health (NIH) for over 15 years, the DSID project has a team that includes a chemist, biologists, IT analysts and statisticians. The research is based on fundamental principles of analytical chemistry, nutrition and public health. For multivitamin/mineral and omega-3 fatty acid studies, dietary supplement samples are purchased according to statistically developed sampling plans for products representative of the US market. The products are sent to contracted laboratories for the analysis of ingredient content. Botanical dietary supplements, including green tea, turmeric and cranberry products have been analyzed in smaller studies. In addition to determining how the analytical content of supplements compares to label claims, we also assess the performance quality of dietary supplements using United States Pharmacopeia protocols for disintegration and dissolution testing. Laboratory data and other related information are stored in Microsoft Access in-house databases. SAS and R programs are utilized for evaluation and statistical analysis of large datasets of laboratory data. Results are reported on the project website, at monthly meetings with the office of Dietary Supplements at NIH, and in articles published in peer-reviewed journals.

Note: This is not a laboratory position. Samples, including quality control materials, are sent to collaborating and contracted laboratories for analysis.

The ideal candidate will have a MS in Chemistry, Biology or a related field plus at least 3 years of experience in scientific research, with at least 1 year in a lead or supervisory role.

Minimum requirements are a BS in Chemistry, Biology or a related field plus at least 5 years of experience in scientific research, with least 1 year in a lead or supervisory role.

Required experience: Experience researching the scientific literature, writing reports, and proposals; experience with statistics and data analysis; excellent communication and analytical thinking skills. Must be able to work with a high degree of initiative and self-motivation; must possess excellent time and project management skills and be able to handle multiple priorities and resolve complex problems.

Preferred experience: Experience with analytical testing of ingredients and components in dietary supplements or foods, quality control methods for laboratory testing, and performance testing of dosage forms; knowledge and experience with nutrition science and nutrition research; extensive experience researching the scientific literature and writing reports, proposals and preparing presentations; expertise with data analysis, especially using Microsoft Excel and data management, especially using Microsoft Access; extensive experience with statistical analysis, programming, and database development.

The successful candidate will coordinate multiple directions/elements of this research program including study design and laboratory data assessment and analysis. This position requires the ability to use technical knowledge to make judgments and decisions, and to work independently as well as cooperatively as a team member to achieve project goals within deadlines.

This is a full time contracted position. Excellent health insurance and retirement benefits and generous holiday, vacation, and sick leave are included. Salary is commensurate with qualifications and experience. This position will soon be transitioning to a hybrid of telework and on-site work in Beltsville, MD.

Researchers are hired through the University of Maryland (UMD; in College Park, MD. On the UMD job posting, this position is listed as a Faculty Associate position.
