researching a technology that could be used to help treat or prevent substance use disorders.

Using technology and your knowledge of Substance Use Disorder (SUD) have a research idea directly related to Substance Use Disorder (SUD) or that could be extended or adapted to be useful for SUD.
For a platform technology, the research idea must be broad enough to address multiple conditions, or indications, including SUD. There are many factors that can affect whether an individual uses or misuses substances, receives a diagnosis of SUD, gets access to treatment, and even continues with treatment. Any type of substance use disorder will do and should be the foundation for new biomedical startups.
