Lawrence B. Solum is an internationally recognized legal theorist who works in constitutional theory, procedure and the philosophy of law. Solum contributes to debates in constitutional theory and normative legal theory. He is especially interested in the intersection of law with the philosophy of language and with moral and political philosophy.

He also works on problems of law and technology, including Internet governance, copyright policy and patent law. His pathbreaking article, “Legal Personhood for Artificial Intelligences,” published in the early 1990s, is widely acknowledged as far ahead of its time.
