Hi, I'm Dr. Alistair Tiefenbacher, a Data Scientist, Bioinformatician & Statistician living in Austria
Bridging cutting-edge research with real-world healthcare applications through AI and machine learning. Explore my journey from cancer genomics research to AI-powered medical devices.
About Me
With over a decade of experience in data science and bioinformatics at top institutions worldwide, I've led the development of AI-powered medical diagnosis systems achieving >90% diagnostic accuracy. My work spans cancer genomics research at Cambridge, protein structure prediction at Oxford, electronic health record screening at Symptoma, and now digital health innovation at Xund. I specialize in translating complex biological and medical data into actionable insights through machine learning, having published 15+ peer-reviewed papers in Nature, Cancer Research, and other leading journals. My unique strength lies in bridging the gap between cutting-edge research and real-world healthcare applications, from developing COVID-19 screening tools used by governments to pioneering personalized cancer treatment strategies.
Research
My research focuses on the intersection of artificial intelligence and healthcare, with expertise spanning three key areas: Medical AI Systems - developing and certifying diagnostic algorithms that meet regulatory standards; Cancer Genomics - analyzing tumor heterogeneity and drug response patterns using machine learning; and Digital Health Innovation - creating scalable solutions for population health monitoring and personalized medicine.
At Xund, I lead the company-wide transition to scalable ML frameworks to enable sustainable product development. Further, I provide the technical expertise for medical AI certification, ensuring our machine learning models meet the stringent requirements for clinical deployment. My approach combines rigorous statistical validation with real-world clinical testing, bridging the gap between research innovation and practical healthcare applications. I believe in developing AI systems that augment rather than replace clinical expertise, creating tools that empower healthcare providers to make better decisions for their patients.
