According to Joelle Barral and @fryrsquared, AI-powered digital twins—realistic virtual replicas of humans or organs—are revolutionizing medical research by enabling the creation of digital cohorts for clinical trials. Their discussion highlights how these AI-driven models can simulate patient responses, rapidly generate crucial data on drug safety and efficacy, and significantly reduce the time and cost associated with traditional clinical studies. This approach not only streamlines regulatory processes but also opens new business opportunities for AI companies specializing in healthcare simulation and predictive analytics (source: company podcast featuring Joelle Barral and @fryrsquared).
