MedAI #50: AI for Clinical Trials and Precision Medicine | Ruishan Liu

Title: AI for Clinical Trials and Precision Medicine

Speaker: Ruishan Liu

Abstract:
Clinical trials are the gate-keeper of medicine but can be very costly and lengthy to conduct. Precision medicine transforms healthcare but is limited by available clinical knowledge. This talk explores how AI can help both — make clinical trials more efficient and generate hypotheses for precision medicine. I will first discuss Trial Pathfinder, a computational framework that simulates synthetic patient cohorts from medical records to optimize cancer trial designs (Liu et al. Nature 2021). Trial Pathfinder enables inclusive criteria and data valuation for clinical trials, benefiting diverse patients and trial sponsors. In the second part, I will discuss how to quantify the effectiveness of cancer therapies in patients with specific mutations (Liu et al. Nature Medicine 2022). This work demonstrates how computational analysis of large real-world data generates insights, hypotheses and resources to enable precision oncology.

Speaker Bio:
Ruishan Liu is a postdoctoral researcher in the Department of Biomedical Data Science at Stanford University, working with Prof. James Zou. She received her PhD in the Department of Electrical Engineering at Stanford University in 2022. She is broadly interested in the intersection of machine learning and applications in human diseases, health and genomics.

The MedAI Group Exchange Sessions are a platform where we can critically examine key topics in AI and medicine, generate fresh ideas and discussion around their intersection and most importantly, learn from each other.

We will be having weekly sessions where invited speakers will give a talk presenting their work followed by an interactive discussion and Q&A. Our sessions are held every Thursday from 1pm-2pm PST.
