Nahal and Tanya attended the 12th Adhesion GPCR workshop in Düsseldorf, Germany.  Nahal gave an excellent talk on her project and the lab's work on the Adgrg6 (Gpr126) signalling pathway in the zebrafish model, and Tanya chaired the session Shaping Tissues: Development, Polarity & Morphogenesis.

We also enjoyed the School of Biosciences Annual Research Symposium here in Sheffield, with fascinating and thought-provoking guest lectures from Martin Warren (Quadram Institute) and Nick Lane (University College London).  

Aaron and Nick submitted images from the lab to the Jarema Malicki Image Competition:

Fiery Olfaction

Antibody staining of cilia (pink/orange) and phalloidin staining of actin (white) to show the olfactory pit of a 5-day-old zebrafish embryo. The cilia beat continuously to draw water into the olfactory pit which brings odorant molecules into close proximity with odorant receptors. This allows the fish to smell their environment in real time. A lateral line neuromast is also visible (top left). Zeiss Airyscan 2 imaging.

Congratulations to Nahal on her PhD graduation!

Our collaborator Elena Scarpa (University of Cambridge) has led a project using the beautiful sox10-driven EB3-GFP transgenic line that Sarah and Mar generated in our lab.  The line can be used to visualise growing microtubule ends (EB3 comets) in the ear and in neural crest cells, and is based on previous published studies, including Stepanova et al., 2003 and Butler et al., 2010.  

Full details and source references are in the manuscript, which is now available on bioRxiv:

Congratulations to first author Soraya Villaseca and all the team!  

The video clip below shows the transgenic line in action:

Sarah, Aaron, Ethan and Tanya all attended the lively 13th European Zebrafish Meeting in Vienna, Austria.  Aaron and Tanya gave talks, and Sarah and Ethan presented posters.

June 2026

We attended the Bateson Centre Symposium, where Nahal gave an excellent talk on her research project, and other lab members presented posters.  Many thanks to Phil Elks and Emily Noël for organising a great day of science!

Tanya gave a talk on zebrafish olfactory ionocytes and rod cells at the UK Cilia and Centrosome Network Spring Meeting at the University of Leeds.  Many thanks to Colin Johnson, Pleasantine Mill and the leadership team for organising such a great meeting.

Ethan gave an excellent talk on his PhD work in the 3rd year Postgraduate Symposium in the School of Mathematical and Physical Sciences.

May 2026

Aaron gave an excellent talk on his PhD project work at the DRN and MCB annual Postgraduate Research Symposium.

Congratulations to Aaron and Ethan, who have both been awarded travel grants to attend the 13th European Zebrafish Meeting in Vienna in July.

Aaron's grant is from the European Zebrafish Society, and Ethan's is from the Institute of Physics.

A warm welcome to Keira Bond, who is joining us from April–June as a part-time technical assistant.  Keira is currently a final year student on our Biochemistry and Genetics degree programme, and has completed a genomics placement at the Julia Garnham Centre. She holds an Elite Sports Performance Scholarship and has represented the USA in National and World Championship Cycling events. Keira is also the Co-President of the University of Sheffield Cycling club, and a Volunteer Coach for the Sheffield Youth Cycling Club.

Aaron presented a poster of his PhD work at the Faculty of Science Doctoral School Showcase 2026:

It was a lively event, with around 100 posters from PhD students across the Faculty of Science.

Tanya gave a talk "Pierced ears and ear rings: Epithelial fusion and fracture in the developing zebrafish inner ear" at the Warwick Medical School, University of Warwick, hosted by Professor Tim Saunders, with a full day of discussions with staff and students.

March 2026

Sarah and Tanya presented a poster of the lab's work at the BSDB Spring Meeting 'Molecules to Morphogenesis' at the University of Warwick.  

As part of a showcase of the Human Developmental Biology Resource (HDBR) Atlas, there was a beautiful 3D-printed human inner ear on display:

Goodbye and good luck to Haseeb Qureshi, who has finished his postdoc in the lab and leaves us for new adventures.  Pints, pies and peas at Nottingham House for a good Sheffield send-off!

The lab also enjoyed a delicious Iranian dinner at Qashqai Kitchen, Sheffield.  Thanks to Nahal for organising!
