Research Intern (Protein Preservation/Hydrogel)

Onsite Internship in Marlborough, MA.


3+ months with potential to extend to a maximum of 12 months.


As a Research Intern, you will play a key role in developing and testing innovative strategies for the cryopreservation of therapeutic proteins. You will be expected to design and execute experiments systematically, analyze data, and report findings weekly. This position offers a unique opportunity to translate a small-scale preservation system into a larger format suitable for use in biopharmaceutical manufacturing. You will collaborate with internal experts in biomaterials, protein chemistry and engineering to explore various topics required to assess feasibility including formulation, process, equipment, and economics.


This hands-on position provides a unique opportunity to work at the interface of biomaterials science and protein biopharmaceuticals, contributing to cutting-edge research in biopharmaceutical storage and delivery. You will gain practical experience in material stabilization techniques, protein analytics, and scale-up methodologies. Your work will have a real-world impact, helping to advance next-generation solutions for protein stabilization and transport.

What You Will Accomplish Together With Us:

• Development & testing of biomaterial-based protein stabilization platforms
• Characterize platform formulations under different environmental and mechanical stress conditions
• Assess formulation performance using a range of analytical techniques to verify efficacy and consistency
• Collaborate with an interdisciplinary team to scale up these lab-scale formulations for potential application in large-scale biopharmaceutical manufacturing

What Will Convince Us:

• Currently pursuing M.S. in Biomaterials Science, Chemistry, Bioengineering, Biophysics, or a related field, or in a PHD program
• Hands-on experience with biomaterials systems in an academic or industry setting
• Experience with protein characterization techniques (e.g., spectroscopy, light scattering)
• Familiarity with protein stabilization & aggregation mechanisms from lab experience in biomaterials, formulation science, or pharmaceutical research
• Ability to systematically design experiments, collect data, and present findings in technical reports

We Value:

• Collaborative mindset – ability to work with interdisciplinary teams (scientists & engineers)
• Curiosity and problem-solving ability – excited about innovative approaches to biomaterials and protein science
• Identification with our core values: Sustainability, Openness, Enjoyment
