Experience / Research + engineering

Research questions.
Working ML systems.

I develop models, test what they improve, and build the systems that bring them into use. My work spans recommendation, foundation-model adaptation, multimodal learning, and computer vision.

Applied Scientist

Treverse LLC

September 2025 – Present
Nashville, Tennessee

Founding member of the Machine Learning Team. I design models and build the training and serving systems behind re-commerce applications.

  • Recommendation systems: Designed graph-based retrieval models and built their training and serving stack. The initial sales-based release increased sales per exposed buyer by 12.62% and checkout-user rate by 3.21% in its experiment. Extended the system with neural ranking, bid-history signals, and cold-start handling. The subsequent version has a separate evaluation.
  • Foundation models for re-commerce: Developing a re-commerce foundation model, beginning with auction value prediction. Fine-tuned a pretrained language model for regression, compared it with specialist models, and implemented GPU serving with vLLM. Broader applications are ongoing research.
  • ML infrastructure: Built a shared platform on AWS and Kubernetes to automate training workflows and model releases, using Airflow, Terraform, and Argo CD. Added monitoring for model-serving services. Read the platform case study.

Earlier work includes an edge-vision presort system integrating cameras, Jetson inference, and operator workflows.

Lead AI Data Science Researcher

AI Negotiation Lab @ Vanderbilt University

October 2023 – May 2025
Nashville, Tennessee

Advisor: Ray Friedman

  • LLM annotation: Led development of a system that codes negotiation transcripts, reducing estimated annotation cost from $5,000 to $3 per transcript and increasing human–AI agreement from 30% to 80% in our later evaluation. Transcript-level context and repeated-run consistency checks support inspection of uncertain labels.
  • Negotiation agents: Built LLM-based simulations with heterogeneous agent behavior to study variation across negotiation strategies and outcomes.
  • Research software: Built fine-tuning pipelines and web interfaces for researchers to annotate transcripts, run experiments, and compare models.

The work was presented at the 2025 AI Negotiation Summit at Harvard and MIT and at the International Association for Chinese Management Research annual meeting. Read the project overview.

Algorithm Engineer

Suzhou AGV Robot Co. Ltd.

June 2022 – April 2023
Suzhou, Jiangsu, China

Designed and delivered computer vision for warehouse stock detection and management, with deployments across approximately 30 warehouses.

  • End-to-end perception: Owned camera setup, image collection and labeling, OpenCV/PyTorch model development, and deployment. The system detects storage status and shelf alignment in warehouse operations.
  • Efficient inference: Exported models to ONNX and optimized inference for resource-constrained hardware.
  • Robotics integration: Connected live stock-status updates to the central warehouse control system coordinating automated guided vehicles (AGVs), with data services and an operator interface. Also improved ROS localization and deployment workflows.

Graduate Research Assistant

Network and Data Science Lab @ Vanderbilt University

June 2024 – May 2025
Nashville, Tennessee

Advisor: Tyler Derr

Studied multimodal learning across vision, graph, and language representations.

  • Vision–Language: First-authored Inverse-LLaVA, a 7B model with text-to-vision fusion trained without LLaVA-1.5's separate 558K-example alignment stage. Released model weights, reproducible comparisons across nine benchmarks, and component, supervision, and scaling studies. The instruction-only recipe uses 45.6% fewer task-training examples; benchmark differences are task-dependent.
  • Graph–Text: Implemented a Temporal Graph Attention Network (TGAT)–LLM pipeline to generate textual node attributes from interaction histories. Evaluated it on the Venmo social graph; designed a follow-up evaluation for Amazon review data.

Professional Research Assistant

Vanderbilt University

October 2023 – January 2025
Nashville, Tennessee

Advisor: Markus Eberl

  • I improved ancient mortar classification accuracy from 60% to 97% by training Vision Transformers on 10 million images.
  • I developed a vision-only provenance algorithm that reduced similarity-analysis runtime from months to minutes. At the time of the original project write-up, a manuscript describing the work was in preparation.
