Hi, this is Zifeng. I am the co-founder and head of AI at Keji.AI. Before that, I did my PhD in Computer Science at UIUC , advised by Prof. Jimeng Sun. I develop AI to accelerate scientific discovery in medicine, specifically:
- Literature research: accelerating the study search, screening, and data extraction from the literature to generate novel hypotheses and clinical evidence[Nat. Commun.'25, npj Digit. Med.'25]
- Clinical research: developing AI models and workflows to enhance the design, execution, and analysis of clinical trials[Nat. Commun.'24, EMNLP'23, EMNLP'22]
Our research was featured by: Nature, NIH News, NIH Director's Blog, POLITICO, AUA News, Azure Government, Editors' Highlights at Nat. Commun.
Keji.AI is a startup focusing on accelerating and improving clinical research through the power of artificial intelligence. We build foundational models and AI agents that empower researchers, pharmaceutical companies, and healthcare providers to design better trials, synthesize evidence faster, and ultimately bring life-saving therapies to patients sooner.
