Engineering, Systems & Datasets

My research is supported by systems I build: agent runtimes, model connectors, experiment orchestration, logging, evaluation, deployment infrastructure, a published clinical video dataset, and lower-level hardware and verification projects.

01

AI systems and research infrastructure

The common substrate under the FORGE, compound-agent, and multi-turn studies.

  • Multi-provider LLM inference

    Unified connectors across API providers with retries, pooling, rate-limit handling, and configuration management.

  • Agent harness and tool execution

    ReAct-style hierarchical harnesses with bounded specialist interfaces and tool execution over simulator APIs.

  • Experiment orchestration

    Parallel, seeded, resumable runs: 3,475 episodes in one study and 84,540 trajectories in another.

  • Configuration-driven agent definitions

    Every condition, topology, and prompt variant declared in versioned configuration so a run is reproducible from one file.

  • Logging and token accounting

    Structured per-step trajectory logs and per-call token accounting behind every cost figure reported.

  • Evaluation pipelines

    Survival and hazard estimation, failure-rationale labeling with human audit, and cost-performance frontier analysis.

  • Reproducibility tooling

    Archived Zenodo artifacts and documented reproduction paths. All ACM reproducibility badges on both CAIS papers.

  • Docker and GPU workflows

    Containerized simulators and analysis. GPU training for sparse autoencoders and video transformers.

02

Applied ML systems and datasets

  • Infant Care Video Dataset

    2024–2025

    A privacy-compliant NICU intervention dataset and a video-transformer benchmark.

    • 4,144 videos across 12 classes
    • TimeSformer and MotionFormer fine-tuned and benchmarked
    • Up to 94% top-1 accuracy on neonatal interventions
  • Bandit-Driven Essay Grader

    2025

    A multi-armed bandit agent that selects among grading prompts per essay to minimize inference cost.

    • Four grading recipes with adaptive prompt selection
    • Cost and reliability accounting per decision
    • 78.4% reduction in LLM calls
  • Federated Anomaly Detection

    2024

    A federated autoencoder pipeline for anomaly detection from network traffic logs.

    • Containerized Mininet traffic simulation
    • Federated autoencoder training across clients
    • Network log analysis pipeline

03

Hardware and low-level systems

Secondary evidence of systems depth: design verification, CPU design, and a fabricated CMOS circuit.

  • RISC-V design-verification testbench

    2025

    UVM-inspired scripted and classic class-based UVM self-checking testbenches with riscv-dv constrained-random stimulus.

    • 8-seed regression with zero failures
    • 88% line, 79% branch, 65% automatic Questa coverage (UCDB merged to an HTML dashboard)
    • Two adder properties formally verified in SymbiYosys (depth 20)
  • RV32I single-cycle CPU

    2022

    A synthesizable Patterson–Hennessy-style RV32I core in Verilog written from the official RISC-V specification.

    • Xilinx simulation testbench with a 20-instruction assembly regression
    • Covers arithmetic, branch, load/store, and jump paths with GTKWave traces
  • CMOS pseudo-random sequence generator

    2022

    Full-chip layout of a 5-bit LFSR PRSG with an on-chip two-phase clock on the CUSoI SOI CMOS multi-project wafer.

    • DRC/LVS closed in the Cadence design suite
    • Fabricated and validated: 31-state ≈2.7 kHz output on a probe station

Contact

Building reliable AI systems requires both research and engineering.

I’m interested in research engineering, applied research, agent infrastructure, evaluation, reliability, interpretability, and research-to-production work.
