Martin Fink, PhD

Director Pharmacometrics


Martin Fink is a quantitative drug developer with long-standing experience across various stages of drug development. His emphasis on using question based approaches and clear communication are highly appreciated and support his customer-focused working style. Martin has also a strong interest in all quality related aspects, be it modeling methodology or processes, collecting adequate information by using an adequate study design to keeping the main goals in mind to inform decision making.

Martin did his PhD at the University of Graz on physiological  models of the cardio-vascular system for blood pressure control, and on respiratory control, before working as PostDoc at UCSD and Oxford University on Cardiac Cell models related to QT interval and drugs eliciting Torsade de Pointes. Transitioning to Novartis he learned Modeling & Simulation supporting drug development for different parts of the broad portfolio. This also allowed him to understand the intricacies of drug development and the essentials of communication within an interdisciplinary team.

Christian Tönsing, PhD

Modeling & Simulation Scientist


Dr. Christian Tönsing is an experienced modeler working in the field of Systems Biology and Computational Biology since 2011. 

He has several years of experience in model development for non-linear and highly complex systems. Christian has a background in Physics and started his research in Systems Biology and Data Analysis at the Physics department at the University of Freiburg, Germany. Over the past years, he worked on statistical approaches for data analysis and numerical optimization methods for parameter estimation in ordinary differential equations.

During his PhD and post-doctoral studies, he developed methods for the quantitative modeling of human diseases and applied for diverse biological systems. Applications range from infectious disease modeling for the Zika virus (ZIKV) and for the SARS-CoV-2 corona virus, over custom statistical approaches for breast cancer research, to data-based mechanistic models for signaling pathways of hematopoiesis in red blood cells.

Using MATLAB and R, he applied diverse mathematical methods related to statistical inference, uncertainty and identifiability analysis in interdisciplinary research collaborations in close collaboration with wet-lab partners.

He joined the IntiQuan team in October 2022

Miriam Stuke, MSc

Modelling & Simulation Scientist


Miriam Stuke comes from the interdisciplinary background of nanoscience (B.Sc., M.Sc. at the University of Basel), studying subjects at the intersection of physics, chemistry, and biology. During her master`s studies, Miriam focused on in silico approaches in chemistry. She has applied mechanistic modeling to fragment-based drug discovery and tested the sensitivity of such modeling approaches. For her master’s thesis, she investigated the sensitivity of machine learning predictions to how molecules were described, for which she received the MARVEL INSPIRE Potentials fellowships from the Swiss National Centres of Competence in Research (NCCRs).

Miriam worked at the University of Basel as an associate on nuclear pore transportation and at LYO-X AG as a PK/PD Modeler. Miriam has over two years of experience in modeling and simulations working with QSP and PK/PD models to analyze preclinical and translation studies for the development of biologics. Since December 2022, Miriam is working as a modeling and simulation scientist at IntiQuan.
