I am a fifth year graduate student at University of Chicago. I am interested in partial differential equations, such as kinetic equations and integro-differential equations. My advisor is Luis Silvestre.

Research

1. Dissipation estimates of the Fisher information for the Landau equation (2024)
2. Bounds for the optimal constant of the Bakry-Émery Γ₂ criterion inequality on RP^d-1 (2024)
3. Global existence for an isotropic Landau model with David Bowman. To appear in SIAM Journal of Mathematical Analysis (SIMA).
4. Local regularity for the space-homogeneous Landau equation with very soft potentials with François Golse, Cyril Imbert, Alexis F. Vasseur. To appear in Journal of Evoution Equations.
5. Entropy dissipation estimates for the Landau equation with Coulomb potentials To appear in Kinetic and Related Models.
