Cell culture at the heart of IVF

IVF consists in generating and cultivating embryos for up to 5 days in the lab before transfering it to the patient's womb.  Cultivating cells, and embryos alike, can be challenging: there are issues of sterility, human intervention, environmental factors, media content, all which might impact IVF in uncontrolled ways.

A crucial task consists in examining embryos through a microscope daily to ensure their viability. This can take a lot of time and is often only performed qualitatively, with doctors having to annotate and extract visually key morphological information.

We believe IVF can be improved by automating more of its cell culture quality control and image analysis.

ImVitro was co-founded by Alexandra Boussommier-Calleja and Maryame Boulhajat.


Alexandra Boussommier Calleja, PhD

Co-founder & CEO


Felipe Delestro Matos, PhD

Senior Data Scientist


Alexandra is a biomedical engineer, trained in top schools in Switzerland, UK and US.

Her PhD and Postdoc revolved around the study of ex vivo and in vitro models of different diseases, at the tissue and cellular level (e.g. organs on chips).

   She has raised more than 300K for her own research, was awarded the CRI Irvington fellowship for her post-doc to study cancer-immune cell interactions using microfluidic tools. She then obtained a Marie Curie fellowship from the European Union to join Elvesys in Paris, a microfluidic company and to kick-start her own company.




Felipe obtained a  Ph.D. in cellular biology at the École Normale Supérieure in Paris after initiating his scientific career as a biotechnological engineer at UNESP in Brazil.

He developed techniques and a patent for the application of AI aiming at embryo classification, specializing in the analysis of 3D+Time imaging data.

He is at the core of ImVitro’s R&D, applying his image analysis knowledge to improve the reliability of IVF.
