About
I’m Charles Renshaw-Whitman, a researcher in AI cognition and alignment.
Outside of my work, I enjoy studying physics, pharmacology, economics, philosophy, and history. I am an avid language-learner, and am proficient in Chinese, Latin, and Ancient Greek. I can read French and Portuguese, and am working on Russian. I also enjoy running, zhan zhuang, and meditation.
I value hard work, simplicity, curiosity, and integrity. I believe in a moral imperative, sed prudentius, technologically to eliminate intense involuntary suffering.

I study the foundations of interpretability with the aim of building better ontologies for understanding cognition and neural networks. Tongue-fifty-percent-in-cheek, my guiding aim is to “solve neuroscience”.
Research profile
My background spans mechanical engineering, applied physics, sustainable energy technology, and self-directed study in mathematics and machine learning. My research combines technical work in mathematical ML with broader questions from neuroscience, agent foundations, alignment, and cognitive science.
I aim to find ways to make the alignment problem tractable by characterising the actual architecture of learned intelligences - insofar as humans are not argmaxers, I wish to understand why. I hope that better understanding these constraints will permit us to ‘thread the needle’ of the alignment problem.
My technical work has drawn on spectral methods, asymptotics, universality, information geometry, and statistical physics. I have historically focused on asymptotic arguments and universality to try and understand neural learning systems; more recently, I have been thinking about alternative routes to natural ontologies for neural learners. My more exotic interests in this connection include neural Darwinism and Kantian/Heideggerian philosophies of cognition.
Selected research and writing
Published research notes
- Power Laws in NNs: A Possible Mechanism for Inductive Bias towards Sparse Representations (2026). Investigates whether heavy-tailed weight spectra provide a mechanism for learned sparse representations.
- Coalitional Darwinism (2026). Uses selection under noise to study selectability, coalitions, and the emergence of higher-level units of agency.
- Information in Continua (2026; three-part research draft). Develops a resolution-centered, kernel-based analogue of information theory for continuous spaces and computations. The underlying ideas are active research; the structure and exposition remain under revision. Part II · Part III
Work in progress
- Free-Body Diagrams for Neural Networks. An empirical and conceptual project asking whether neural-network subsystems can be studied by holding their surroundings approximately fixed, tested through controlled activation replay and downstream relaxation.
- Feature Learning in the Genome. Develops a mathematical correspondence between selection for evolvability in biological genomes and feature learning in neural networks, with proposed applications to interpretability and alignment.
- Analogy Machines. An early-stage account of scale-free analogical structure in LLMs and humans, connecting representation learning with cognition, neuroscience, and epistemology.
