About the role

Regeneron's Product Biochemistry group, located in Tarrytown NY, is seeking an Associate Scientistwho will be responsible for providing in-depth characterization of nucleic acid therapeutics and Lipid Nanoparticles (LNP). In this exciting role, you will be expected to participate in technology innovation efforts aimed at enhancing our understanding of oligonucleotides and LNPs in solution and address both pre-clinical and late-stage program needs.

A Typical Day in the Role of Associate Scientist Might Look Like:

  • Develop analytical methods and conduct biochemical and biophysical characterization experiments to elucidate quality attributes of gene therapy candidates. Help solve problems in real time.

  • Provide support for basic research efforts. Ability to adapt and/or optimize methods described in the literature.

  • Conduct time-sensitive biochemical and extended characterization of siRNAs to meet regulatory timelines.

  • Provide input on experimental design and suggest method adaptations to address specific needs of a program or attributes of colloidal systems.

  • Additional responsibilities will include method development of advanced technologies that evaluate the purity and/or thermodynamic and hydrodynamic interactions of siRNAs, mRNAs, CRISPR gRNA and LNP-nucleic acid complexes.

  • Support forced degradation studies evaluating environmental stressors and their impact on the stability of siRNA, LNPs and their cargos.

  • Document experiments, results, and findings in electronic laboratory notebook; presents work at group and departmental meetings, contributes to drafting of protocols, method development reports, regulatory submission sections, and peer-reviewed publications.

  • Maintain instruments, troubleshoots instrumental/experimental problems, and order/maintain supplies.
