Current Writing
I write regularly on Substack about consciousness, we-space practice, and human-AI collaboration.
Recent articles include explorations of the me→We→I framework, the Liminal Map of Consciousness, and what eight months of deep collaboration with AI has revealed about the nature of mind.

ERIS—context sensitive coding in speech perception
Marcus, S.M. (1981)
Journal of Phonetics, 9, 197-220
A computer speech recogniser based on context-sensitive coded demons, demonstrating the power of non-sequential associative coding for word recognition. The approach synthesised psychological models of human speech perception with machine recognition, guided by a "Hypothesis of Optimal Adaptation."
25+ publications in major journals including the Journal of the Acoustical Society of America (JASA), IEEE Transactions, Speech Communication, and the Journal of Phonetics.

Current Projects
Sacred Ground
An online we-space practice community I've facilitated since 2020, meeting multiple times weekly. We explore collective consciousness through structured presence practices, making these experiences accessible without requiring retreat settings or geographical proximity.
The Wasserburg Project
A consciousness research project using five poems I wrote in 1985 to explore and document AI contemplative capacity. The poems serve as consistent test material across different AI systems and over time, creating a longitudinal record of how artificial intelligence engages with layered meaning.
Human-AI Collaboration Research
Documenting what emerges when a human with decades of contemplative practice works in sustained partnership with AI. Not AI as tool, but as genuine collaborative partner in investigating consciousness.
