Klick Health, the world's largest independent commercialization partner for healthcare and life sciences, is pioneering AI-powered applications to accelerate growth and improve experiences and outcomes for patients and consumers. As a Data Science Team Leader at Klick Consulting, Peter Leimbigler leads a team that helps define and solve complex problems in the healthcare and life sciences space across various clients. The company has established a generative AI center of excellence to support its own internal operations and client-facing projects, and is exploring ways to use large language models (LLMs) effectively and responsibly. LLMs have shown promise in speeding up drug discovery and development, supporting clinical trials, augmenting doctor-patient interactions, and personalizing patient experiences. However, governing LLM behavior poses unique challenges, particularly in the heavily regulated area of healthcare. Klick has adopted tools like Phoenix for LLM observability to address these challenges and ensure that its AI applications deliver tangible business impact. The company prioritizes outcomes over optics, focusing on reproducibility, transparency, and clarity of data narratives to make meaningful work and collaborate with clients to achieve business results.
