Scientific mission

Through our research we continue to answer new questions about the nature of the infant cry, while designing and developing efficient signal-processing and machine-learning algorithms for analysis.

Ubenwa Research

Clinical development pipeline

We are developing a robust platform for early screening and monitoring of a range of neurological and respiratory conditions affecting infants.
