breussMartin Breuss, Assistant Professor University of Colorado. Martin undertook a diploma thesis in the lab of Vic Small on cytoskeletal dynamics in cell migration. Martin joined the Keays lab in 2009 and worked on the role of tubulin genes in neurodevelopment and disease. He showed that mutations in the tubulin isoform TUBB5 cause microcephaly with structural brain abnormalities. See Breuss et al, Cell Reports, 2012. Martin was the first PhD student to graduate from the Keays lab. Martin was awarded an EMBO Fellowship which supported his post-doctoral work with Dr Joesph Gleeson at UCSD. In 2020 Martin was appointed to a faculty position at the University of Colorado School of Medicine.


pascal-smallPascal Malkemper, Max Plank group leader at CAESAR in Bonn. Pascal did his Masters in biology with focus on neuroscience at the Ruhr-University Bochum, Germany.

Landler Lukas_smallLukas Landler, Faculty University of Natural Resources and Life Sciences. Lukas did his diploma in Zoology at the University of Vienna studying the magnetic compass of toads (see Landler & Gollmann Front. Zool. 2011). He performed his  doctoral studies at Virginia Tech under the supervision of John B. Phillips on the spontaneous orientation responses of turtles, crayfish and woodpeckers. He graduated in Spring 2015 and joined the Keays Lab, where he explored magnetoreception in model systems (Lander et al, e-life 2018). In 2019 Lukas was appointed to a faculty position at University of Natural Resources and Life Sciences, Vienna (


Thomas_small2Thomas Gstrein performed his undergraduate studies at the University of Innsbruck in biological sciences before joining the Masters program in molecular biology at the University of Vienna. He undertook his PhD in the Keays lab focusing on the molecular mechanisms that facilitate neuronal migration.  Thomas showed that a hypomorphic mutation in Vps15 caused a hippocampal migration defect in the Marble mouse. He further demonstrated that this mutation perturbs endosomal-lysosomal trafficking and autophagy, resulting in an upregulation of Nischarin, which inhibits Pak1 signaling (Gstrein et al, Nature Neuroscience 2018). Thomas now works for Teva Pharmaceuticals as a consultant, and he still can’t beat Dave at squash.

Fernanda Reza, graduated from the National Autonomous University of Mexico with a bachelors degree in Genomic Sciences.

She joined the Keays lab in 2017 for her masters thesis, focusing on genes involved in brain developmental disorders. In 2020 Fernanda started her doctoral studies with Magdalena Goetz at LMU on axonal repair.


mattias lauwersMattias Lauwers joined the Keays lab in 2011 as a PhD student. Mattias was responsible for discovering the “cuticulosome” in Avian hair cells (Lauwers et al, Current Biology, 2013). Mattias was a brilliant experimentalist, a patient and thoughtful scientist, a lover of all things made of cheese, and a wonderful friend. He died following a mountain biking accident on September 12th 2014. There are no words to describe how much we miss him.



Jasmin SmallJasmin Morandell joined the Keays lab in 2013 as a Masters student. Jasmin’s thesis focused on Tubb2b, a gene that has been implicated in a variety of brain disorders. Jasmin showed that Tubb2b undergoes a developmental transition in cortical neurons. Tubb2b is abundantly expressed in both progenitors and post-mitotic neurons in development, but is restricted to the glial lineage in adulthood (See Breuss and Morandell, Journal of Comparative Neurology 2015). Jasmin is currently undertaking a doctorate at the Austrian Institute of Technology.



christopher-treiberChristoph Treiber was the first student to join the Keays lab in 2008. As a diploma student he showed that clusters of iron-rich cells in the upper beak of pigeons are macrophages not magnetosensitive neurons. Christoph is currently undertaking a doctorate at Oxford University with Professor Scott Waddel. See Treiber et al, Nature, 2012.




andreas-braunAndreas Braun joined the Keays lab in 2009 as a diploma student. Andreas profiled the expression of tubulin genes during neurodevelopment. He showed that Tuba8 is expressed at very low levels in the developing brain, whereas Tubb5 is enriched in stem cells and post-mitotic neurons. Andreas completed his doctorate at the Centre for Gene Regulation in Barcelona, before pursing a career in management consulting. See Braun et al, AJHG, 2010.



frenk-lorenzLorenz Fenk joined the Keays lab in 2009 as a bachelor student. Lorenz investigated whether C57/Bl6 mice can be conditioned to magnetic stimuli.
