Dr Mart Ratas is the Research CogStack Developer & Research Administrator in the Department of Biostatistics & Health Informatics at the Institute of Psychiatry, Psychology & Neuroscience at King's College London.

He contributes to the development and maintenance of CogStack, an ecosystem of tools that enables researchers and healthcare professionals to make better use of electronic health record data. Their work focuses primarily on natural language processing (NLP), developing tools that transform unstructured clinical text into structured information for research and healthcare applications.

Since joining the team, Dr Ratas has taken on increasing responsibility for the development of MedCAT, CogStack's clinical NLP platform, including the development of new models and leading the major redevelopment of the platform in MedCAT v2. They have contributed to a wide range of research and development projects involving MedCAT and related tools, working to support applications across clinical research and healthcare data science.

Dr Ratas has also contributed to the dissemination and development of research through conference presentations and academic publications, as well as leading funding and grant applications to support the continued development of MedCAT and related technologies. Their work sits at the intersection of software engineering, clinical informatics and applied research, helping to bridge the gap between research methods and their practical use with real-world healthcare data.

Dr Ratas holds a PhD in Natural Sciences from Tallinn University of Technology which focused on applied mathematics and numerical methods.
