My current work focuses on high‑fidelity mechanical modeling, contact interaction, and fluid-structure interaction (FSI) of endovascular devices inside intracranial aneurysms. I also research in‑silico computational FEM placement, design, and computer‑aided design & modeling of neurovascular implants. I design and model nature‑inspired magnetic soft robotic swimmers and swarms, and develop computational methods for FSI and hard‑magnetic soft materials.
