Fruit fly embryo under lightsheet microscopy

A short video that I made about the embryonic development of the likeable Drosophila, also known as fruit fly or vinegar fly, won an honorable mention in the Small World in Motion.

A single embryo imaged from four different angles.

The details on the techniques I used and the video on its full resolution are available for download and re-use on the Wikimedia Commons.

A typical lightsheet microscopy session

Here is how a typical session of imaging embryos under Lightsheet Microscopy goes. A glimpse into my day-to-day work :)

Assemble the incubation chamber:

Collect and mount the embryos:

Typical lightsheet microscopy session.

Acquire a short timelapse from multiple angles:

Transfer (lots of) data for image processing ;)

Interview for the Portrait of Science

Recently, I had the honor to be interviewed for the Portrait of Science. It’s a beautiful project created by Magdalena Gonciarz to get to know the people who do science (aka the scientists). Check out the project’s Facebook page!

The most important problem in biology

Heading to #embryo2017 today! Wondering how long will Conklin’s words remain current… (120 years and counting)

The most important problem in biology according to Conklin.
