About Me

I work at the intersection of physics-based simulation and applied machine learning. My PhD focused on nonlinear finite element modeling of manufacturing processes — building high-fidelity ABAQUS models with experimental validation under U.S. DOE and Honeywell programs. Today, at Align Technology, I ship production machine learning models for orthodontic treatment planning serving millions of patients annually under FDA regulatory oversight. I'm most interested in problems where domain knowledge changes how a model should be built — physics-informed features, geometric priors, constraint-aware optimization.

Deep Learning Enhanced Treatment Planning for the Invisalign System

Developed production ML/DL models for orthodontic treatment planning, iterating from multivariable regression to a Transformer architecture (multi-head attention) that contributed to a 20% increase in clinical efficacy for millions of patients annually. Led V&V under FDA regulatory oversight across 13+ demographic and clinical dimensions. Generated surrogate training labels via counterfactual analysis across 30,000+ cases, framing attachment placement as a Learning-to-Rank problem (LightGBM LambdaRank) deployed to production processing 1,000+ cases/week.

LLM-based Dental Treatment Assistant & Evaluation Framework

Architected a LangGraph ReAct agent integrating LLMs (Claude, Llama, Gemini) over AWS Bedrock for natural-language querying and modification of orthodontic treatment data, with a 3-category evaluation framework. Built a middleware layer with query sanitization and complexity classification for dynamic per-request model routing; currently being tested as a case screening tool for clinical studies.

Geometric Deep Learning

3D Shape Representation Learning for Orthodontic Attachments

Built a DiffusionNet-based mesh autoencoder encoding variable-topology 3D meshes into 8-12D latent vectors at sub-millimeter fidelity. Conducted systematic AE vs beta-VAE comparison across reconstruction fidelity, generative specificity, disentanglement, and interpolation smoothness. Designed embeddings as drop-in geometric features for the downstream treatment planning Transformer.

Finite Element Modeling of Rock Drilling Processes

Developed a finite element model in ABAQUS for PDC rock cutting simulation using the Drucker-Prager yield criterion with damage evolution to capture failure of granite under varying crack density, orientation, and confining pressure (0-100 MPa). Calibrated constitutive model parameters through uniaxial and diametrical compression testing with experimental validation. Built a MATLAB-based node separation algorithm for parametric crack studies. Constructed a laboratory-scale rock drilling setup demonstrating 30% reduction in cutting forces from plasma-induced pre-cracking.

Machining of Additively Manufactured Metals

Developed a 2D finite element model in ABAQUS with Johnson-Cook plasticity and damage criteria to simulate serrated chip formation during turning of Ti-6Al-4V. Investigated the effect of fracture energy on chip morphology. Analyzed machinability of additively manufactured Ti-6Al-4V, A205, and 17-4 SS through a full factorial DOE with SEM-EDS microstructural characterization.
