Later this year I’ll be joining the Comparative Embryology of Marine Invertebrates (CEMI) course as an instructor. It will be held from November 25th to December 8th, 2026, at CEBIMar–USP, São Sebastião, Brazil. CEBIMar is where I did my master’s thesis about the embryonic development of a sea biscuit and where the Oceano and Cifonauta […]

LiSIAW 2026
The Light-Sheet Image Analysis Workshop organized by LiSIUM took place last week at Universidad Mayor in Santiago, Chile. There were 24 participants from all over Latin America—Argentina, Brazil, Chile, Colombia, Mexico, and Uruguay! Marina Cuenca, Agustin Corbat, and I (the instructors) gave lectures and practicals ranging from the basics of digital images to advanced workflows […]
The winners of this year’s Nikon Small World in Motion are out, and my favorite is the 5th place entry, A newborn sea urchin walking along the seabed by Alvaro Migotto: It’s adorable to see these newly metamorphosed echinoderms and their long and chubby tube feet learning how to walk. This scene reminded me of […]
The Light-Sheet Image Analysis Workshop is a five-day intensive course that will take place in Santiago, Chile, from January 5–9, 2026, designed for students and researchers who wish to gain foundational skills in the processing and analysis of light-sheet microscopy imaging data. The application deadline has been extended until August 8, 2025! The workshop is […]

Ceratitis open peer review
I reviewed a paper last year about the embryonic development of Ceratitis capitata, the Mediterranean fruit fly (or medfly). The authors used time-lapse recordings of whole embryos made with lightsheet microscopy to create a comprehensive staging system for the embryogenesis of the species. It was one of the first reviews that I signed (disclosed my […]

HHMI Janelia Beautiful Biology
HHMI Janelia has launched Beautiful Biology, a… beautiful initiative that: “(…) aims to cultivate interest and curiosity in the life sciences through this portal of stunning images showcasing the largely invisible biological world.” From their About page. This is very much aligned with the motivation behind the Ocean: hidden life photo exhibition and the Cifonauta database itself—so I’m excited (no surprises). The […]
The mitotic waves made it onto the Sächsische Zeitung, a regional newspaper published in Dresden (thanks to Katrin Boes from MPI-CBG). They wrote a nice little piece about the video. I translated it to English (using DeepL…). You can read it below. Scientist receives coveted film award Dresden researcher turns little fruit flies into movie […]

Colormap for mitotic waves
In a recent email exchange, someone asked me what the colors in the video of mitotic waves mean and how did I get them. How the microscope technique results in the array of colors in the cells (purple to yellow and red). Could you briefly explain where the colors come from and how you visualised […]
