Biologics Formulation Intern: NIR Moisture Analytics & PAT

Zoetis; Kalamazoo (MI); On-site; USD 30,000 - 50,000; Full time

Job summary

Zoetis seeks a Biologics Formulations Summer Intern to support development of a moisture-prediction model for lyophilized drug products. You will work on rapid, non-destructive NIR methods, collect KF and NIR data, and build chemometric models to predict moisture levels. The internship emphasizes hands-on lab work and PAT implementation planning.

Location is Kalamazoo, MI, with a 10–12 week timeframe. Ideal candidates are enrolled in relevant sciences, comfortable with data tools, and eager to

Qualifications

• Currently enrolled in a bachelor’s degree in Pharmaceutical Sciences, Analytical Chemistry, Chemical/Biomedical Engineering, or a related field.
• Experience working in a laboratory setting, operating laboratory equipment, recording data.
• Interested in learning Lyophilization techniques, PAT, spectroscopy (NIR/IR), and/or analytical methods.
• Comfortable working with data (e.g. Excel, JMP, or similar).
• Detail-oriented, structured, and able to document experimental work.
• Effective communication skills

Responsibilities

• Familiarize and operate freeze-drying/lyophilization equipment and prepare formulations across a defined range of moisture-content targets.
• Perform Karl Fischer (KF) titration and acquire Near-Infrared (NIR) spectra using established sample-handling and laboratory procedures.
• Develop, optimize, and evaluate chemometric models—such as PLS regression—to correlate NIR spectra with KF moisture measurements.
• Process and analyze experimental data, assess model performance, and support method optimization to minimize false-positive and false-negative results.
• Conduct laboratory experiments under supervision, document findings, and contribute to technical reports and posters/presentations and analytical-method documentation supporting future PAT implementation.
