About Me

I build and study systems that coordinate - whether that's autonomous agents sharing a task, or 238 countries trading with each other. My work sits at the intersection of agentic LLM systems and network science, and both come from the same instinct: that the structure of how things connect explains more than the properties of the things themselves.

I co-developed SW-KG, a multi-agent LLM coordination architecture that borrows small-world network topology to cut communication overhead between agents. My master's thesis modeled 35 years of UN Comtrade bilateral trade data as a geospatially embedded network and found that global trade is robust to random disruption but fragile to targeted removal of hub economies. Alongside the research, I've built production retrieval-augmented generation pipelines over enterprise data sources and designed database schemas and workflow architecture for a real-time tracking application.

I care about knowing what my results do and don't show - most of what I've learned came from the experiments that didn't work. Currently looking for applied scientist and AI engineer roles in generative AI, agentic systems, and network or supply chain intelligence.

Featured Projects

SW-KG — Multi-Agent LLM Coordination

Co-developed a multi-agent LLM coordination architecture that arranges agents in a Watts–Strogatz small-world graph (K=4, p=0.3) rather than a fully connected mesh, layered with a token economy and a hub-promotion mechanism. Measured 91.8% token reduction and 12.19× latency speedup at 10×100 agent scale, validated through controlled ablation studies isolating each component. Published as a preprint.

SW-KG: Small-World Topology for Multi-Agent LLM Coordination

Preprint · Figshare · DOI 10.6084/m9.figshare.32519487

Multi-agent LLM systems spend most of their tokens talking to each other. SW-KG addresses this structurally rather than through prompt engineering — by changing the topology agents communicate over. Agents are arranged in a Watts–Strogatz small-world graph (K=4, p=0.3), which preserves short average path length between any two nodes while using far fewer edges than a complete graph. A token economy meters communication cost, and a hub-promotion mechanism elevates frequently-routed nodes.

Key Results:
  • 91.8% reduction in token usage against baseline at 10×100 agent scale
  • 12.19× latency speedup at the same scale
  • Each architectural component isolated through controlled ablation studies
Limitations & Current Work:
  • Hub promotion did not carry its weight on token metrics in isolation — it improved routing behavior but cost more than it saved in tested configurations
  • The theoretical complexity bound in the preprint is stronger than the empirical results at tested scales support
  • Current traversal does not fully exploit the shortcut edges the topology provides
  • A v2 is in progress exploring a hybrid design pairing HNSW-based retrieval with SW-KG's coordination layer

Small-World Spatial Network Analysis of Global Supply Chains Using International Trade Data (1988–2022)

Manuscript in Submission | Target: Peer-Reviewed Journal (Supply Chain / Network Science)

Modeled global supply chains as geospatially embedded small-world networks, integrating network science and spatial analysis across 238 reporting economies and 16,000+ trade links. Key findings: pronounced small-world structure, strong regional clustering, and asymmetric resilience under targeted disruptions. Manuscript and code repository will be linked after submission.

Key Insights:
  • Global supply chains show strong small-world properties (σ > 1.2 across all intervals) with high clustering and short path lengths
  • Networks are resilient to random failures but vulnerable to targeted hub removal — ~15–20% hub removal fragments ~80% of the network
  • Regional clusters (EU, East Asia, North America) have high internal clustering, with Asia-Pacific reaching C = 0.91
  • Geography and clustering are strongly correlated (r = 0.72)
  • Cross-regional corridors are critical for efficiency and global connectivity

Earthquake Pattern Analysis Using Clustering, Forecasting & Machine Learning: A Global Study (1960–2023)

Published · Journal of Research in Environmental and Earth Sciences (QUEST Journals), Vol. 11 Issue 6 | Read Paper

A global study of seismic activity from 1960 to 2023, combining unsupervised clustering, time-series forecasting, and supervised risk classification over 28,000+ earthquake records from the USGS National Earthquake Information Center catalog.

Results:
  • K-Means (K=5, selected via elbow method) segmented events into five clusters aligning with major tectonic boundaries — the Pacific Ring of Fire, Himalayan Belt, Mid-Atlantic Ridge, and San Andreas Fault system
  • DBSCAN (eps=0.5, min_samples=10) isolated dense seismic zones and separated outlier events from clustered activity
  • SARIMA magnitude forecasting achieved 5.2% MAPE on a 2016–2023 holdout, with residual analysis showing minimal bias
  • Random Forest risk classification reached 72.2% accuracy (74.1% precision, 70.8% recall); a Decision Tree baseline reached 67.5%
A Note on Data Provenance:
  • The location-probability ranking surfaced a limitation worth documenting: several of the highest-probability sites correspond to former nuclear test locations — the Nevada Test Site and Semipalatinsk in Kazakhstan — rather than to natural seismicity. The source catalog does not distinguish anthropogenic events from tectonic ones, and no filter was applied. A revised version addressing this is planned.
