Papers
A computational model of coronary arteries with in-stent restenosis coupling hemodynamics and pharmacokinetics with growth mechanics (2025)
Ranno, Manjunatha, Koritzius, et al.
A patient-specific computational model coupling hemodynamics, drug kinetics, and tissue growth to investigate in-stent restenosis after drug-eluting stent implantation.
Read PaperOn-the-Fly Calculation of Model Factors for Multi-paradigm Applications (2022)
Protze, Orland, Haldar, Koritzius, Terboven
Originating from my bachelor thesis, introduces a tool to accurately separate and quantify model factors in layered parallel programming paradigms for Hybrid MPI+OpenMP metric, providing deeper insights into sources of inefficiency—such as load imbalance and synchronization overhead—across applications with various concurrency patterns.
