About Me

I'm a UChicago graduate (2024) who studied economics and data science. I am now pursuing an MS Thesis in computer science at Columbia, where I am interested in leveraging information theory & deep learning to better understand modern AI systems and the brain. I hope to do contribute research in the effor to enhance the communication process between humans. My dream would be to enable the transfer of high dimensional information directly between humans, reaching a sort of advanced telepathy.
