About Me
I am a 5th year Ph.D. student at the Courant Institute of Mathematical Sciences, New York University. I am a member of the Geometric Computing Lab where I work with Professor Daniele Panozzo and Denis Zorin. My research focuses on physics simulations in Computer Graphics and optimization problems based on simulations. I received my Bachelor's degree in Applied Mathematics at University of Science and Technology of China in 2020.

ACM Transaction on Graphics (SIGGRAPH ASIA), 2024.
Summary:
We use shape optimization and topology search to design families of microstructures
approximating the ideal shock-protecting behavior. We present an algorithmic pipeline for the
optimal design of such families combining differentiable nonlinear homogenization with
self-contact and an optimization algorithm. We fabricate the designs with existing 3D printing
technologies and validate their effectiveness through experimental testing.

Summary:
We introduce a general differentiable solver for time-dependent deformation problems with
contact and friction. It support static and dynamic problems, and differentiation with respect
to
all physical parameters involved, including shape, elastic parameters, friction coefficient, and
initial conditions. Our analytically derived adjoint formulation is over 10x faster than
automatic differentiation.

Summary:
Two-scale topology optimization, combined with the design of microstructure families with a
broad range of effective material parameters, is increasingly widely used in many fabrication
applications to achieve a target deformation behavior for a variety of objects. We adapt this
approach to complex shapes in situations when preserving the shape's surface is important. We
propose an automated and robust pipeline based on this approach with the ability of handling 2D
and 3D shapes of high complexity.
arXiv, 2021
Summary:
We introduce a collection of benchmark problems in 2D and 3D (geometry description and boundary
conditions), including simple cases with known analytic solution, classical experimental setups,
and complex geometries with fabricated solutions for evaluation of numerical schemes for
incompressible Navier-Stokes equations in laminar flow regime. We compare the performance of a
representative selection of most broadly used algorithms for Navier-Stokes equations on this set
of problems.
