I am a programmer and researcher who wants to make computers smarter. This led me from computer science into neuroscience, where I studied the smartest machine that we know of, and then back into AI, since deep learning was going further than I'd ever expected.

I am excited about LLM-based tools, particularly those that could help us discover the next set of AI architectures.
