Researchers in Yongjie Jessica Zhang’s lab develop novel algorithms on biomodeling at molecular, cellular, tissue and organ scales, and explore applications in various application fields. The group is mainly focused on applications in biomedical fields, but is also working on projects in other fields including mechanical engineering, materials science, and electrical engineering.
George Tallman Ladd and Florence Barrett Ladd Professor of Mechanical Engineering
The Computational Bio-Modeling Lab's research includes computational geometry (especially mesh generation), computer graphics, visualization, finite element method, isogeometric analysis and their applications in computational biomedicine, computational biology, and engineering. We are mainly focusing on applications in biomedical fields, but we are also working on projects in mechanical engineering, materials science, electrical engineering, civil engineering, architecture, geological engineering, and petroleum engineering.

This research focuses on developing novel, robust, automatic, and accurate techniques to construct high-fidelity geometric models and quality finite element meshes directly from volumetric imaging data for arbitrarily complicated topology and geometry.
Through computer design software we integrate geometry and analysis by constructing volumetric spline parameterization and use them in isogeometric analysis directly.
We develop automatic and robust algorithms and software tools for high-fidelity (correct topology and accurate geometry) geometric modeling and mesh generation for polycrystalline materials. This work supports the understanding, control, and optimization of grain boundary dominated materials properties: GBCD/GBED distribution and mechanics characterization.
