July 2018: Bye Bye Steffi...


It is time for Stephanie Niklaus to move on. After doing her Master thesis and her PhD with us, Steffi was snatch up by Roche Pharmaceuticals. This is a loss for academia, but we are proud that she will bring her expertise in zebrafish genetics and visual diagnostics to the pharmaceutical industry. Our team will lose on the most active members and we will struggle to replace your expertise of basically all we do in the lab. The lab will feel different without you and your treats from Graubünden. We wish you all the best for your next challenge and hope that we both can help to bridge the industrial/academic divide.


July 2018: UZH Forschungskredit


Congratulations to Adriana Hotz. Her proposal to use a zebrafish mutant to model epilepsy was awarded the prestigious CandDoc Forschungskredit Award of the University.


July 2018: Goodbye Anja...


Anja Enz recently graduated with her Master’s degree and will start as a junior consultant at Kelly Services soon. Congratulations and all the best for her future endeavors. We will miss one of our most avid sports companions.

May 2018: bye bye Sanne

byebye sanne

Sanne spend six months in the lab to be trained in electroretinography and other fishy business. She is now back in Nijmegen at Radboud University. We will miss you Sanne - it was a pleasure to have you with us! This half a year went way too fast...

January 2018: Children University-Sunburn and fish

There is a nice article ( in german ) about the childern University in the Tagesanzeiger.

Prof. Dr. Stephan Neuhauss is this year again a lecturer at children University. One of his topics: Can fish get a sunburn?

December 2017: Congratulations Dr. André Lehnherr

andre defense

Congratulations to André, after finishing his final PhD exam with flying colors. The event was celebrated in style, lubricated by his other biological interest, namely taming yeast to produce a  number of excellent home brews.

All the best for your future, your Neuhauss-team


July 2017: Stephan Neuhauss the new Vice-Dean for Research and Planning


Congratulations (or Condolences) to Stephan for being elected to become Vice-Dean for Research and Planning of the Faculty of Science, beginning in August 2017.

Good luck and may you make more new friends than enemies.

July 2017: Congratulations to Stephanie (Steffi) Niklaus

defense steffi


Steffi defended her thesis with flying colors, leaving her committee speechless.

All the best of fun for the well-deserved extend trip around the world.


We are happy that you will not leave us yet and will come back to finish and write even more papers.

Proud "Doktorvater" and your team

Latest Publications June/July 2017:


Fish Larvae on Cocaine

Steffi just published the curious finding that cocaine accumulation in the zebrafish eye leads to an increased response of the retina to light. This may be related to changes in light adaptation connected to dopamine signaling. Find the open access link to this single observation see open access at:

Cocaine Accumulation in Zebrafish Eyes Leads to Augmented Amplitudes in the Electroretinogram


Glutamate Transport at the Photoreceptor Synapse Shape Neurotransmission

With perfect timing just before the submission of her thesis, Steffi, Lucia and friends got the long awaited EAAT2 story published. These two paralogs of glutamate transporters represent prime example of subfunctionalization of an ancient gene function. They found that glial-expressed EAAT2a is the main glutamate sink at the cone photoreceptor synapse. EAAT2b in turn is expressed on cone photoreceptors, sporting a large anion leak current, effectively clamping the photoreceptor resting potential. Read the paper for free clicking the link below.

Evolutionary Conservation in the Vertebrate Kidney

Our former PhD student Yuya Sugano published yet another paper from our fruitful collaboration with the Loffing lab from the Institute of Anatomy. In this paper he shows that gene expression is conserved between the mammalian distal convoluted tubule and the zebrafish distal late segment. Interestingly some genes enriched in the mouse are not found to be enriched in the zebrafish. Instead, related homologous genes from the fish are enriched, likely fulfilling a similar function.

June 2017: Congratulations Dr. Irene Ojeda Naharros



Congratulations to Irene Ojeda Naharros, our newly minted

Triple digits of hours tracking fluorescent particles in photoreceptor cells have paid off.

All the best of luck for your postdoc and your growing family!

June 2017: Congratulations to Selin Ozgur



Selin finished her Master in Genetics this May working on camta1 mutants. We will miss your ready smile and your comedian’s talent that made our lunch breaks. All the best for your graduate school applications. 

May 2017: New webpage for the group of Ruxandra Bachmann

Congratulations Ruxandra Bachmann!!!



We are proud and happy to report that Ruxandra got awarded the very prestigious SNF Förderprofessorship of the Swiss National Science Foundation. From this fall on she will be an independent assistant professor at the Institute of Molecular Genetics. Luckily she will continue to be associated with us via her fish work. Incidentally I started my academic career with the same professorship. Congratulations and all the best for starting your completely independent research team. 


Congratulation Dr. Stella Glasauer

It's over - 2nd European Meeting on Phototransduction


The 2nd European Meeting on Phototransduction which took place in September 2016 on the beautiful Monte Verita in Ascona was a full success. The 50 participants from 12 different countries presented and discussed photoransduction in all its depth from biophysical properties to evolution and diseases. 


Yuya Sugano: best thesis prize- Swiss society for anatomy



Yuya Sugano was awarded the best thesis prize at the annual meeting of the Swiss society for anatomy. Congratulations to this well-deserved honor.


Some part of the thesis is published in Kidney Int. 2015 Nov;88(5):1047-56 (Sugano et al;  The Rho-GTPase binding protein IQGAP2 is required for the glomerular filtration barrier)
