The J&J IM Discovery, Product Development, & Supply (DPDS) organization helps early career scientists gain the training and experience needed to further develop their careers while addressing the needs of global healthcare.

Postdocs work side-by-side with DPDS scientists on innovative research projects.

They learn the functional role of scientists in the pharmaceutical industry and receive valuable career advice from mentors while building a network of professional contacts and developing the skills needed to advance their careers.

We are seeking a talented Postdoctoral scientist to join our Pharmaceutical and Material Sciences (PMS) team, which is part of the global Pharmaceutical Product Development & Supply (PPDS) organization within J&J IM R&D to be based in Beerse, Antwerp, Belgium.

The PMS team is responsible for pre-formulation and biopharmaceutics, solid state form selection and understanding, and material selection and qualification to provide end-to-end support to the J&J IM synthetic modality portfolio.
The main objective of this 18-months Postdoc project is to develop novel PBPK capabilities that integrate the key insights gained from in vitro and preclinical experiments within the currently available PBPK frameworks to allow better predictions of the plasma concentration time profile of drugs formulated as amorphous solid dispersions.

The project is partially funded by Flanders innovation & entrepreneurship (VLAIO).
Efforts in this project will mainly focus on mathematical modeling of key in vitro biopharmaceutics experiments such as drug solubility, dissolution, and others to confirm/estimate key input parameters such as amorphous solubility (aqueous and in presence of bile micelles), ionization constants, solubility factors, precipitation rate etc.

prior to using them within PBPK Models.

Novel PBPK methodologies will be developed that leverage our improved understanding of ASD release mechanisms (congruent or incongruent) and the formation of drug-rich nanodroplets (liquid-liquid phase separation) and their particle size distribution towards intestinal drug permeation.
As a Postdoctoral scientist, you will operate under limited supervision with a high level of autonomy to transform drug delivery challenges into innovative ideas and practical solutions consistent with project objectives.
