Core Expertise

As a Computational Cosmologist, I develop advanced gradient flow techniques for visualizing and interpreting high-dimensional Cosmic Microwave Background (CMB) data. My work bridges topological data analysis, information geometry, and cosmological parameter estimation to reveal hidden structures in the universe's earliest light.

Technical Capabilities

1. High-Dimensional CMB Data Processing

• Dimensionality Reduction:

  • Applied t-SNE and UMAP to project Planck/SPT-3G data (∼10⁷ dimensions) into 3D interactive maps

  • Identified anomalous cold spots via persistent homology (Betti number analysis)

• Gradient Flow Optimization:

  • Developed CMBFlow – A Riemannian manifold optimizer for cosmological parameter spaces (Ωₘ, Ω_Λ, σ₈)

2. Topological Feature Extraction

• Non-Gaussianity Detection:

  • Trained Wasserstein GANs to separate primordial signals from lensing artifacts (f_NL < 1.5)

  • Mapped gradient flows around B-mode polarization vortices (r < 0.01 sensitivity)

3. Open-Science Tools

• WebGL Visualization Suite:

  • Real-time exploration of CMB harmonic space (ℓ < 2500) with VR support

• Educational Modules:

  • Created "CMB Topology for Beginners" Jupyter notebooks (500+ citations)

Impact & Collaborations

• Discovery Support:

  • Contributed to Atacama Cosmology Telescope's 2024 detection of cosmic textures

• Interdisciplinary Synergy:

  • Adapted methods for exoplanet atmosphere phase space analysis

• Public Outreach:

  • Featured in Scientific American's "The Universe in Gradient Colors"

Signature Innovations

• Algorithm: Geodesic Information Flow – Accelerated MCMC sampling by 20×

• Publication: "Topological Shadows of Inflation" (Physical Review Letters, 2025)

• Dataset: Released CMB-3D – First interactive multiresolution CMB map bank

Optional Customizations

• For Academia: "Proposed new quantile normalization for comparing CMB/SZ effect manifolds"

• For Industry: "Consultant to SpaceX Starlink on CMB-aware beam calibration"

• For Media: "CMB gradient art exhibited at NYC Museum of Mathematics"
