I build computational tools for studying feedback in financial systems and software for experimental research. This archive brings together my co-authored conference work, research notes, talks, and ongoing manuscripts, with links to the original sources.
Conference contributions
Co-authored work in the 2025 International System Dynamics Conference proceedings. Each entry links to its published abstract; research notes summarize the question, approach, and findings.
Turning banking supervisors’ mental models into simulations to study feedback, uncertainty, and assessments of financial stability.
Question
How can the relationships identified by banking supervisors be simulated directly, without first building a conventional data-intensive model?
Approach
Structured supervisor debriefings inform a directed signed graph. Graph-algebraic simulation, centrality and cycle analysis, and Gaussian mixture models examine network behavior and uncertainty.
Finding
The conference abstract reports that the elicited models tend to overestimate long-term capital and earnings decline. Parameter experiments explore how dampening and responsiveness can instead support stability.
My contribution
I developed simulation software, replication materials, and tutorials supporting the research. The Flow-CLD project page explains the engine, diagnostics, and reproducible workflows.
Manuscript record
The supplied manuscript is dated March 18, 2025 and identifies this work as ISDC submission #1139. It shares the title and author order of the conference contribution above.

Using causal-loop models to examine how Indigenous governance, digital connectivity, and sustainable finance interact in Alaska.
Question
How do green finance and digital infrastructure intersect with Indigenous sovereignty and community priorities in Alaska?
Approach
The study combines a synthesis of literature, research from Northeastern’s Arctic Studies Lab, and causal-loop diagrams spanning environmental, economic, technological, and cultural relationships.
Finding
The abstract identifies governance authority and data sovereignty as central to participation and distributional outcomes. It also describes how connectivity can expand educational opportunities while creating new digital divides.

Acknowledged for helpful discussions. I am not a co-author of this paper. My related experimental-software work at the Rowland Institute is described separately.
Earlier title
The June 2025 bioRxiv version was titled “Drosophila learn about properties of objects through physical interaction,” the title used in an earlier CV. The August 2025 revision uses the later published title. These are earlier versions of the same study, with the same five authors and a helpful-discussions acknowledgment.
