DPS is a multi-disciplinary research group that provides drug delivery, pre-formulation and formulation support for peptides, biologics and,small molecules at the development and drug discovery interface. -Our team is responsible for the characterization of pre-clinical drug candidates' physicochemical properties.- We aim to work with partner groups to select candidates with optimal development properties while balancing all other key therapeutic properties.- Our research also covers identification of preclinical formulations for pharmacology and toxicology studies and ideally for FIH across a variety of administration routes and modalities (biologics, small molecules, peptides, and oligonucleotides).

-

In this exciting role, you will focus on the characterization, early formulation development, developability -assessment and delivery approaches for various peptide modalities. -Goals include a) early formulation screening and developability assessment as well as b) recommendation of single candidate together with partner functions. Innovation in peptide formulation and drug delivery will be critical. You will serve as a team member and execute lab experiments yourself with minimal supervision.- You will generate these key data sets and convey their meaning to the teams you work on and develop strategies to optimize molecules and their formulations.- Within DPS you will have the opportunity to contribute to departmental scientific initiatives as an individual contributor and as a technical lead to mentor junior scientists. You will also closely interact with other key functions required for the progression of clinical candidate selection including Medicinal Chemistry, Drug Metabolism and Pharmacokinetics, Nonclinical Drug Safety and Drug Product team.
