Biography

I am a post-doctoral fellow working on biomechanical models for the real-time simulation of soft tissues.
In the past I have been focusing on the incorporation of topological changes into these biomechanical models.
Currently I am particularly investigating in the correct representation of complex geometry in the biomechanical model (I might add, after discussion with Stéphane: and the generation of non-cuboid hexahedral meshes).

I received a masters of science majoring in mathematics from the Virginia Polytechnic Institute and State University (Virginia Tech) at Blacksburg, Virgina, United States of America. After returning from studying abroad, I won the “Research Student Award” of the Karlsruhe Institute of Technology, Germany, supporting the outstanding research idea of my diploma thesis on the “Simulation of surgical cutting using the Extended Finite Element Method (X-FEM)”. In june 2013 I received the diploma of the Karlsruhe Institute of Technology (KIT), Germany. The work of the diploma thesis has been extended to a preprint entitled as “Simulation of Complex Cuts in Soft Tissue with the Extended Finite Element Method (X-FEM)”. Between october 2013 and january 2014 I have been working as research engineer in the research group Mimesis lead by Stéphane Cotin. In that time I started incorporating topological changes into the C++ finite element framework SOFA (www.sofa-framework.org).

Between January 2014 and March 2017 I conducted my PhD addressing the “Modelling and real-time simulation of topological changes in soft tissue”.

More information on the theoretical nature of this work can be found in the publication “Virtual Cutting of deformable objects based on efficient topological operations”. And an interesting application in augmented reality has been described first for silicone objects in “Augmented Reality during Cutting and Tearing of Deformable Objects” and then in the surgical context in “Surgical Augmented Reality with Topological Changes” and “Handling Topological Changes during Elastic Registration: Application to Augmented Reality in Laparoscopic Surgery” .
