ALTERNATIVE will develop an innovative platform able to detect the cardiotoxicity of chemicals and their biotransformation products. The novel platform will enable regulators and industry to identify, quantify and prevent cardiotoxic co-exposures to industrial chemicals and pharmaceuticals in a cost-effective way. ALTERNATIVE will particularly focus on cardiotoxic effects on the older people, which is of high relevance in view of the aging European population and the high spread of cardiovascular diseases.


Within the scope of the project and cloud data platform will be developed to enable deployment, operation and access of the machine learning data modes as well as to facilitate the data gathering and analysis between ALTERNATIVE partners.


Milestones:

  • Implementation of Cloud Data Platform

  • Integration of ML model and data source into the cloud data platform


Tasks:

  • Consortium coordination for SI ES TI EOOD

  • Management of the development team
