SYS.REF // COGNITIVE-INSPIRED ARCHITECTURES

I am currently a Founding Engineer at a [STEALTH STARTUP] where I predominately develop cognitive-inspired ML systems. Our research predominantly revolves around Representation Learning, Novel ML Algorithms, and Mechanistic Interpretability.

My research Interests lie in Neuro-Symbolic AI, specifically in cognitive-inspired systems that learn continuously from few examples, grow their own concept hierarchies the way people do, and stay explainable and interpretable at every layer. 
I also enjoy deploying Edge AI to see how far we can push local compute to aid those in the field.

Deep Taxonomic Networks for Unsupervised Hierarchical Prototype Discovery

A deep latent-variable approach that optimizes a large latent hierarchy to automatically discover taxonomic structure and prototype clusters directly from unlabeled data; statistical optimization walking a gradient space toward emergent topology.

Taxonomic Networks: A Representation for Neuro-Symbolic Pairing

Frames taxonomic networks as the shared representation that pairs connectionist learning with symbolic structure: top-down symbol instantiation and discrete knowledge routing over a learned abstraction tree that stays inspectable.

Cross-Language Typicality Effects in a Multilingual Large Language Model

Tests whether GPT-4o aligns with human typicality norms across five languages, probing the synchronization of statistical neural maps with the structured, human-like conceptual frameworks they must mirror.
