About – Michael Crowther

Michael was for many years an academic biostatistician, rising to Associate Professor of Biostatistics at the University of Leicester, before relocating to Stockholm in 2021 to pursue some new challenges. He is an expert in survival analysis and joint longitudinal-survival models, having made numerous contributions to the fields, and widely respected as a statistical software developer. He has developed and taught many training courses on his research, and is a Fellow of the UK Higher Education Academy.
