Washington University interim policy on visitors

Update as of March 9, 2020

Whether or not they are exhibiting symptoms, visitors who have been in locations with an elevated risk of COVID-19 exposure within the past 14 days are not allowed to visit campus or attend university events. In addition, visitors who have had direct contact with a patient confirmed to have COVID-19 or with someone who is under care for suspected exposure to COVID-19 are not allowed to visit campus or attend university events within 14 days of such contact.

Our apologies for any inconvenience this poses to your plans to visit.

Shin-Ichiro Imai, MD, PhD, and Alessia Grozio, PhD, study in the lab.

Current research

Our research is highly diverse and includes topics ranging from embryogenesis, cell reprogramming and organogenesis to aging and stem cell engineering.

Our ongoing and future work will focus on new and emerging areas of developmental biology, such as epigenetics and genomics.

Lilianna Solnica-Krezel, PhD in Zebrafish lab

Model systems

We house one of the largest zebrafish facilities in the world. Along with zebrafish (D. rerio), we study several other model systems, including the fruit fly (D. melanogaster), nematode (C. elegans) and mouse (M. musculus), as well as tissue culture systems and embryonic stem cells.
