Research

The systems layer where enterprise AI becomes reliable.

My research formalizes the space between retrieval and reasoning: context compilation, memory runtimes, precision-aware context, governed agentic delivery, and the control planes that make AI usable at enterprise scale.

Foundational program

Context Compilation Trilogy

A Context Compilation research program: one foundational paper introduces the theory, followed by a three-paper trilogy on representation, runtime, and precision-aware optimization.

Toward a Theory of Context Compilation for Human-AI Systems

This paper proposes that context in AI systems should not merely be retrieved or remembered — it should be compiled. Context Compilation Theory introduces a formal framework where context is selected, transformed, governed, optimized, and lowered into executable context packs for downstream models, agents, and interfaces. The paper defines Context IR as a portable intermediate representation, analogous to compiler IRs in traditional software, and presents CompileBench as a benchmark specification for measuring compilation quality rather than recall alone.

Context IR and Compiler Passes for Enterprise AI

Paper 1 operationalizes Context Compilation Theory. It defines a four-level Context IR, a compiler-pass taxonomy for enterprise context pipelines, formalizes context graph breaks, and treats governance as intrinsic to compilation through policy-as-types and a portable Context ABI.

Paged Context Memory: Runtime Systems for Evidence Blocks, Locality, Speculation, Linking, and Policy Preservation

Paper 2 extends the trilogy from semantics into runtime behavior. It argues that compiled context should live like managed memory: evidence blocks enter working sets, locality governs movement, speculative execution prepares likely futures, context GC removes dead state, and provenance remains attached through lifecycle transitions.

Quantized Context: Utility-Preserving Compression and Mixed-Precision Context Assembly

Paper 3 turns optimization into a first-class concern. It defines a semantic precision ladder, a distortion model for compiled context, mixed-precision assembly strategies, and recovery-aware compression so systems can stay cheap until risk, policy, or task criticality demands higher fidelity.

Cybernetic Software Delivery: A Governed Lifecycle for Agentic Engineering Work

This paper argues that the traditional SDLC cannot govern a world where AI agents produce engineering artifacts. Cybernetic Software Delivery (CSD) reframes delivery as a control system — a closed-loop model with humans, agents, tools, evaluations, and feedback. The primary unit of delivery becomes the governed run: a bounded, observable, policy-aware execution of delegated work that is fully reconstructable from storage. The paper introduces a nine-stage lifecycle, a five-category artifact taxonomy, 13 new metrics extending DORA, and a four-tier governance framework.

Research themes

The recurring systems questions.

Layers

Context Compilation

A research program for how AI systems should compile context across representation, runtime, and precision-aware optimization rather than treating retrieval as the entire stack.

Unifies fragmented approaches to RAG, memory, runtime discipline, and cost control under one formal context stack.

GitBranch

Cybernetic Software Delivery

A governed lifecycle for engineering work produced by autonomous agents — treating delivery as a closed-loop control system.

Provides the operating model enterprises need when AI agents become first-class producers of engineering artifacts.

Cpu

Agent Operating Systems

Architecture patterns for systems where AI agents are first-class participants — scheduling, resource management, inter-agent communication, and governance.

Enterprises deploying agents need OS-level primitives, not just prompt wrappers.

Brain

Memory Systems for Human-AI Work

How AI preserves continuity of cognition across changing data, models, tools, and experiences — from episodic memory to persistent context graphs.

Without durable memory, AI systems start every interaction from zero. Memory is the bridge between intelligence and usefulness.

Token Economics & AI Infrastructure

The cost structures, optimization strategies, and economic models that determine whether enterprise AI systems are sustainable at scale.

AI costs can spiral without visibility. Token economics is the CFO-level discipline of enterprise AI.

Shield

AI Control Planes & Governance

Governance, observability, policy enforcement, and trust calibration for enterprise AI — the management layer above models and agents.

Enterprise AI without governance is a liability. Control planes make AI auditable, explainable, and safe.
