Senior AI Scientist

Job DescriptionWe are hiring a Senior AI Scientist to support the company in delivering its mission of improving the lives of patients by transforming research into mental illness and dementia. The company is working in this highly innovative area to accelerate the development of new treatments, improve healthcare services, and advance our understanding of complex, debilitating conditions like Major Depressive Disorder, Schizophrenia, Bipolar Disorder and Alzheimer’s disease.To do this, we curate a globally unique dataset of more than 4.6 million patients’ anonymised psychiatric electronic health records (EHRs) for research use. A crucial part of our curation process is the application of AI-enable natural language processing algorithms to structure the free text elements of the EHR (clinical notes, letters, reports etc). Development of these NLP models is the primary focus of our in-house AI team, in which this role sits.The AI Team are primarily responsible for developing and training the Natural Language Processing models that underpin Akrivia’s data structuring pipeline. The goal of this activity is to develop accurate, clinically valid, explainable, and scalable NLP models to extract new structured data from EHR free-text fields. The AI Team collaborate closely with the Research Team (to match the outputs of their models to research needs), the Engineering Team (to embed their models into Akrivia’s data processing pipeline), and with the Client Engagement team (to help platform users apply their model outputs effectively). The AI Team also carry out exploratory research to develop new applications of AI for improving mental health research and treatment.The role will require strong technical skills with a focus on artificial intelligence approaches to natural language processing. A successful candidate will work on developing our existing technology solutions, develop novel applications of AI to solve challenges in the mental health space, and support our users in industry, academia and the NHS to apply our AI-derived data for their own research programs.
