At Regeneron, we use science and innovation to develop life-changing medicines for people with serious diseases. Regeneron is currently seeking multiple 2027 Interns in Bioanalytical, Analytical & Formulation Sciences teams. These groups measure and characterize Regeneron's drug candidates — how much is in a sample, how it behaves in the body, and how to keep it stable — to support preclinical and clinical studies. 

These positions offer the opportunity to contribute to a fast-growing, science-driven organization making a meaningful difference to patients worldwide.  

When & where: 

Location: Tarrytown, NY 

Timeframe: Our internship positions are full-time and onsite from May/June-August

Pay: Intern and Co-op pay ranges are determined by level of education (year in school) and degree program. The hourly rate range for these locations is: $17.90-$50.90 per hour.

What you'll do:

• Support the labs that measure drug candidates and biomarkers in samples from preclinical and clinical studies, some of it under strict regulatory (GLP) standards.

• Projects may include developing and running assays such as ligand-binding assays and LC-MS/MS (mass spectrometry), supporting proteomics and structural biology research, characterizing the structure of complex drug types with advanced mass spectrometry, and running formulation and stability studies to find the best conditions to keep a medicine stable.

• Most projects are hands-on lab work combined with data analysis, careful documentation, and writing up results.

• Basic lab skills (pipetting, reagent preparation, documentation) and chemistry or biochemistry coursework are helpful; mass spectrometry or immunoassay experience is a plus. A few projects are better suited to graduate students.

Relevant majors: Biology, Biochemistry, Chemistry, Biomedical Engineering, Chemical Engineering, Pharmacy

Let's find out if we're a fit:

• Demonstrated leadership in areas such as campus activities, clubs, sports, current or previous work, or within the community preferred
