Heino Andreas


Heino studied agriculture, and after completing his degree, first worked in a consulting company and later on moved on to the University of Halle to work on various projects. Since 2000, he has been working as a technician at the MPI-CBG. He worked in the last years with different model organism like axolotls, frogs, and planarians. Now, in the Tomancak lab, Heino is still continuing his passion of working with water animals through other species, namely Hydra (jellyfish), Macrostomum (flatworm), and Platynereis (segmented worm). In cooperation with other researchers in the lab he maintains and amplifies the three species to enable studies of their embryogenesis and development. Outside of work, Heino likes to hike and to ride his bike.

Matthias Arzt

Software Engineer

Yes, my last name means doctor! But despite the fact that I really work in a research institute. No, I don't have a PhD. So doctor who? I studied mathematics and did my diploma at the Technical University in Dresden. By combining this with a strong interest in software development, I can now enjoy the pleasure of analyzing the fascinating and beautiful image data recorded by my fellow biologist and life scientist. I have been working in the realm of Fiji image analysis software for five years now. Most notably, I came up with Labkit, a Fiji plugin that makes it intuitive to segment gigantic image data. And now I'm really looking forward to analyzing the lineages and tree data structures brought up by embryonic development and regeneration. Outside the Lab I enjoy cycling, gardening and seeing how my son grows up.

Anaïs Bailles


Anaïs did a Bsc and Msc in physics at Paris XI Orsay/Paris-Saclay University, with a focus on biological systems. She was mind-blown by movies of developing embryos, so she decided to start a PhD in developmental biology in Marseille. There, she studied Drosophila morphogenesis at gastrulation, and how tissue contractility and dynamics are controlled by both mechanical and chemical signals. She joined the lab as a postdoc to study the mysterious regeneration of Hydra aggregates, and how a heterogeneous group of cells can self-organize in the presence of noise. For more theoretical approaches to this question, she is working with the Zechner group. She likes long lunch breaks, improv theater and costume parties, or, for something completely different, reading and discussing history and philosophy of science.

Marina Cuenca


Marina has a degree in physics from the University of Buenos Aires and her project is focused on gastrulation mechanobiology. Using Light Sheet and confocal microscopy she observes and quantifies tissue flow. By perturbing the embryo with photomanipulation techniques, she assesses the nature of the morphogenetic events happening during gastrulation in a multi-scale approach, and the interplay of physical forces involved. In her free time, she enjoys doing sports, reading, dancing and painting.

Johannes Girstmair


Born in the Alps of Austria Johannes did his Bachelor and MSc (Molecular Cell and Developmental Biology) studies at the University of Innsbruck. He then continued a PhD under the Marie Curie ‘NEPTUNE’ fellowship at University College London where he used the OpenSPIM for the first time to study the development of a polyclad flatworm, Prostheceraeus crozieri. Currently a postdoc in the group, he continues to study the embryogenesis of different flatworm species with different developmental modes and further advances OpenSPIM systems. He likes to take his two small kids for a hike into the ‘Sächsische Schweiz’ and recently created a publishing platform for fiction books with a friend (

Manan Lalit


Manan graduated in mechanical engineering from IIT Kanpur and then completed a masters in applied mechanics from Chalmers University. From 2014 up till 2017, he worked with acoustics in the automotive industry. During this period, he used to build graphical interfaces and implement solvers for differential equations. Currently, Manan uses computer vision methods to analyze volumetric imaging data in the context of the early development of the Platynereis worm. He likes to doodle, read science fiction and fantasy novels, and follow cricket matches.

Pavel Mejstřík


Pavel was born just 60 km from Dresden, but on the other side of the border in Usti nad Labem. Then, inspired by Gregor Mendel, he moved to Brno to study Genetics and Molecular Biology at Masaryk University. After finishing his Bachelor and Master studies he started to work on cell cycle regulation during early mouse embryo development at Mendel University in Brno. Later on he switched his focus into medical research revealing new prognostic markers in patients with Lymphomas and Leukemias in the Department of Hematooncology at University Hospital in Brno. He has joined Tomancaklab to screen for gene expression patterns in various tissues of Drosophila using high-throughput RNA in situ hybridization and continues to work with different model organisms in the lab. He is interested in a lot of different sport activities, reading books, hiking and discovering new places mainly with his three kids.

Max Petzold

Hiwi Student

Max is an undergrad in Molecular Biology and Biotechnology at the University of Technology in Dresden. Before he decided to enroll at the university he spend two years down under, travelling, working and doing things a backpacker usually does. His enthusiasm for biology and science in general was growing already back in school. For the lab he is primary working on processing and analyzing bio-images either with Fiji or by scripting in Python but also does he take care of the the transgenic Hydra population. When not in the lab he likes to do different sports, eat good or lay back and read a book.

Giulia Serafini


Giulia comes from Italy and completed her undergraduate studies there, at the University of Bologna. She got her BSc in Biotechnology, with a thesis on the characterization of new variants of breast cancer and her MSc in Molecular and Cellular Biology. During her Master work she encountered Drosophila for the first time, studying the protein Awd and its involvement in wingless signaling. She moved to Dresden for her PhD and now is studying the embryonic development of Drosophila melanogaster, with a particular focus on Scab-mediated blastoderm-vitelline envelope attachment and its role in gastrulation. She loves to dance, and in her free time she likes to practice different kinds of dances. She also enjoys going to the theater, reading a book or just having a walk along the Elbe.

Bruno C. Vellutini


Bruno is a biologist fascinated by embryos and evolution. He obtained his BSc and MSc from the University of São Paulo, Brazil, where he studied the life cycle of sea biscuits to understand how they became flat. He then moved to Norway to investigate the evolution of cleavage patterns and body segmentation in spiralians, and obtained his PhD from the University of Bergen. Bruno joined the Tomancak Lab in Dresden to uncover the interplay between genetic patterning and epithelial morphogenesis of a mysterious invagination that divides the head–trunk boundary of flies during gastrulation. He loves imaging living embryos under the microscope and sharing these images and videos online for science outreach. Outside the lab, Bruno enjoys playing basketball, reading, and making music with his bass.

Vinca Yadav


Vinca completed her BSc and Msc at the University of Delhi (Delhi) and the Centre for Human Genetics (Bangalore) respectively. After her MSc, she worked at the Institute for Stem Cell Science and Regenerative Medicine (inStem) as a junior research fellow, to understand the role of nutrient signalling pathways in maintaining quiescence-growth oscillations in nutrient-limited cell populations. Currently, she is a PhD student in our group, working closely with Jonathan Rodenfels' group to understand metabolic strategies adopted by developing embryos of different animal species. Outside of the lab, she dabbles in improv theatre, collects plants, runs, and plays fetch with her cat, Goblin.
