Our lab aims to study human embryo implantation and provide solutions to improve in vitro fertilization (IVF).
The embryonic development of humans (and mammals in general) requires the implantation of the embryo into the walls of the mother uterus. Implantation involves the attachment of the embryo to the uterine lining, termed endometrium, and the invasion of the tissue to form the placenta.
This process is crucial for natural conception and especially for in vitro fertilization (IVF) as only 25% of IVF embryos successfully implant into the mother uterus’ and develop to term. However, despite the central role of implantation in human fertility, the process is still elusive to experimentation because of its inaccessibility.
In our lab we use bioengineering methods to create 3D environments that support embryonic development outside of the mother uterus. Our systems are accessible to imaging tools which allow us to interrogate the genetics, metabolomics and mechanics of the embryo in a high throughput manner. Using our systems we are capable to (i) improve embryo culture conditions and (ii) diagnose embryos with improved implantation potential.
Due to the high translational component of our research, we have established collaboration contracts with the pharma industry, hospitals and venture capital to bring our technology to the clinics and the market.
Our Open Lab is a multidisciplinary environment where biologists, biophysicists, clinicians and business developers synergize to create a unique environment shaped by science and entrepreneurship.

Study on decision making for embryo selection in IVF clinics
One out of seven couples suffers from sub-fertility problems. In vitro fertilization (IVF) is the most commonly used method to assist such couples. As only 30 % of the transferred embryos implant and develop to term, it is common to artificially increase the IVF success rate by transferring multiple embryos. This procedure has the undesirable side effect of multiple pregnancies, generating significant health complications, both for the mother (higher rates of hospitalizations and Caesarean delivery) and for the babies (prematurity, low weight, up to 40x increased risk of early infant death).
The current trend in IVF clinics is to transfer a single embryo and succeed a single pregnancy, as both unsuccessful and multiple pregnancies are physically, emotionally and economically traumatic. Improving the IVF success rate of single embryo transfer by recognizing which embryo has a higher chance to implant is one of the major challenges in ART.
The Bioengineering in Reproductive Health (BRH) group is currently developing a study to better understand in a quantitative way how do IVF clinics around the world make decisions regarding embryo selection for implantation. Due to the limited literature on the topic, the team has decided to request the collaboration of fertility specialists from prestigious clinics worldwide.
With this study, the group’s research goal is to discover which is the best way to help embryologists and fertility clinics in the critical process of selecting the best embryo to transfer to the mother’s uterus. By improving this process, the number of multiple embryo transfers and multiple births is going to decrease, thus increasing the efficacy and safety of IVF.
The best way to explore which is going to be the best way to collaborate in technological progress and help embryologists in this matter is to have a comprehensive understanding of the status quo of IVF decision making. This study will allow a two-fold benefit, providing information and knowledge both to the team and fertility specialists around the world.
