What we believe

"Here's to the crazy ones. The misfits, the rebels, the troublemakers, the round pegs in the square holes, the ones who see things differently. They're not fond of rules, and they have no respect for the status quo. You can quote them, disagree with them, glorify or vilify them. About the only thing you can't do is ignore them. Because they change things - they push the human race forward. And while some may see them as the crazy ones, we see genius. Because the people who are crazy enough to think they can change the world, are the ones who do." --Steve Jobs

"The future depends on some graduate student who is deeply suspicious of everything I have said." -- Geoffrey Hinton

CogAI4Sci team

Our research focuses on developing machine learning methods that enable AI systems to autonomously interact with the world and learn generalizable rules from experience in an efficient and creative manner to achieve automatic self-evolution.

Before starting CogAI4Sci team, Dianbo Liu was a group leader at the Broad Institute of MIT and Harvard. Prior to the Broad Institute, Dianbo worked as a postdoctoral researcher with Prof. Yoshua Bengio (a Turing Award winner) and led the Humanitarian AI team at the Mila-Quebec AI Institute. This followed his fellowship training and studies in medical informatics at Harvard Medical School. Dianbo earned his PhD from the University of Dundee, Scotland, under the supervision of particle physicist Prof. Timothea Newman. During his doctoral studies,he received the Vest Principal Scholarship from the Massachusetts Institute of Technology (MIT) and was a special graduate student at the MIT Computer Science and Artificial Intelligence Lab. Dianbo also co-founded two start-ups, "GeneTank" and "SecureAILabs," to advance AI applications in sciences during his training.

Research aims

Research aims

Our team work on 3 types of Automatic AI Engines, which we refer to as 3 "As"

AI or AI that improves AI. We design machine learning models to autonomously to design and conduct interactions with environment and data to learn from experience aiming at self-evolution. The focus is on post-training of LLMs and memory of agentic systems to learn from experience instead of human data

We improve creativity of generative machine learning models and enable them to propose novel contents, focusing on post-training of LLMs and foundamental mechanisms of diffusion.

We use self-evolving AI with improved creativity to help make new discoveries in biomedical sciences
