Mechanical engineering senior (aerospace minor) at NYU Tandon, applying to aerospace engineering M.S. programs for Fall 2027. I’m interested in high-speed aerodynamics and propulsion for rockets and spacecraft. I write my own simulations to understand the physics, validating them against theory and published data.

| Project | What it does | Focus |
|---|---|---|
| Euler Flow Solver: Shock Tubes & Blunt Bodies · Shock Tube Lab · 1D studies | Compares Rusanov, Roe, and HLLC fluxes with MUSCL limiters against the exact 1D Riemann solution. A 2D cylinder extension checks bow-shock standoff against Billig’s correlation and stagnation pressure against the exact pitot value (within 0.2% at Mach 2–6), and demonstrates HLLC’s carbuncle instability at Mach 6. 65 automated tests. | High-speed CFD |
| Vortex Panel Method Airfoil Solver · Airfoil app | Linear-strength vortex panel solver for 2D airfoils with Kármán–Tsien critical-Mach analysis and an interactive airfoil analysis app, validated against an exact Kármán–Trefftz solution, thin-airfoil theory, and XFOIL. The app includes streamlines, pressure fields, panel convergence and validation comparisons. | Computational aerodynamics |
| Reentry Heating & TPS Thermal Model · Heat Shield Sizer | Sizes a capsule heat shield from an entry trajectory, Sutton–Graves heating, and multi-layer conduction. For the baseline entry, 7.03 cm of LI-900 meets the bondline limit but exceeds the tile’s surface limit; FRCI-12 is the lightest of the three tiles studied that stays within both limits. The browser app re-sizes the shield, compares materials, plots temperature through the wall, and runs parameter studies. | Aerothermodynamics |
Ongoing group work. The public code is the three solvers above.
- Undergraduate Researcher, High-Speed CFD (NYU Tandon, Prof. Nicholas DiZinno, Sept 2026–present): extending a strongly implicit incompressible-flow method to the supersonic blunt-body problem: bow shock, shock standoff, and the mixed subsonic–supersonic region.
- Aerodynamics Lead, Smart Rotor Load Control (NYU Tandon senior design, Aug 2026–present): 3D rotating-frame and dynamic-mesh CFD in ANSYS Fluent, plus OpenFAST BEM modeling for a trailing-edge-flap controller on a scaled NREL 5-MW turbine.
- Propulsion Lead, AIAA Design/Build/Fly (NYU, Nov 2025–present).
