Overview PhosKinTime is a mechanistic framework for reconstructing phosphorylation dynamics from time-resolved molecular measurements and kinase–substrate network information. Scientific question How can time-resolved phosphoproteomic measurements and prior kinase–substrate relationships constrain models of signalling-network dynamics? The work focuses on estimating kinetic behaviour rather than treating each time point as an independent observation. Model and method The framework represents phosphorylation kinetics with ordinary differential equations. Parameter estimation combines global differential-evolution search with constrained sequential least-squares optimization, followed by sensitivity analysis and model diagnostics. ...

Overview This project is a physiologically based pharmacokinetic modelling study of tirzepatide, represented as an SBML-based ordinary differential equation system. Scientific question How can curated clinical measurements and physiological structure be combined in a reproducible model of tirzepatide absorption, distribution and elimination? Model and method The work uses a compartmental PBPK model encoded as coupled ordinary differential equations. Model parameters are estimated against curated clinical measurements, and the model is distributed in an interoperable SBML-based form. ...
