Welcome Celso!

My name is Celso Martins, freshly arrived from Portugal.

I initiated my research career during my B.Sc. in Biology (University of Aveiro, Portugal), when I studied the effects of water hardness and alkalinity in a tiny freshwater cladoceran called Daphnia longispina.

However, I felt dragged to even smaller organisms, so I decided to take an M.Sc. in Microbiology ((University of Aveiro and ISCSEM, Portugal), in which I explored the effects that some antimicrobial polymers (won’t bother you with the names) exerted in the human oral microbiome. Then I spent a few months in a clinical diagnostic team performing molecular studies in cancer and prenatal disorders (Labco Porto, Portugal). After this short experience in a clinical environment, all I wanted was to go back to research! Therefore, I joined Professor Cristina Silva Pereira’s team (ITQB NOVA, Portugal), first as a Research Fellow and later as a PhD student.

My PhD focused on the (nasty) effects that pollutants exert in the soil mycobiota and ultimately revealed that the exposure to those pollutants (and their subsequent biodegradation) elicited molecular tradeoffs related to increased pathogenesis in fungi.

I am now delighted to join Vjestica Lab to explore an entirely new world related to the transcriptional events during and after fission yeast zygotic transition.


Farewell Manuel!

Manuel Bueno is leaving the GTF at the end of April 2021. He will work for Hamilton robotics.

We wish him all the best!


Welcome to Claudia!

I’m Clàudia Salat Canela and I‘ve just arrived in Lausanne from Barcelona.

After obtaining a master’s degree in Biomedical Research (UPF, Barcelona), I joined Elena Hidalgo and José Ayté’s lab as a PhD student. 
During my doctoral studies, I focused on the role of MAP kinases in regulating gene transcription and cell polarity during stress responses in fission yeast.

I’m thrilled to have recently joined Vjestica Lab.  My postdoctoral research will explore the molecular mechanisms of zygotic specification in fission yeast. 


Welcome to Ayo!

My name is Ayo Araoyinbo and I’ve recently joined the lab of Aleksander Vjestica as a Ph.D. to work on the cell biology and genetics of fission yeast sexual life cycle.

Before now, I completed my Microbiology B.Sc. in Nigeria after which I moved to the UK for my Masters in Applied Biomedical Science Research. For my project at the Astbury Centre for Structural Molecular Biology at Leeds, I worked on the molecular and functional characterization of the Adenosine Nucleotide Transporters in budding yeast and then was employed under a BBSRC fellowship to develop yeast strains to metabolise low pH and glycerol rich distillery wastes, this progressed through a scholarship to become my Masters of Research project.

I look forward to getting to know you all over the next few years.


Welcome back to Justine!

Guess who’s back? 

I am Justine Pascual and I received my Master’s degree in Bioengineering from the University of Toulouse where I originally come from.

After moving to Switzerland, I started working in the laboratory of Fisun Hamaratoglu at the CIG on growth control and patterning in Drosophila.

Then, I joined Etienne Meylan at the EPFL to work on lung cancer, and more precisely, on the impact of microenvironment and metabolism on tumor development. But I missed flies too much!!!
Having the opportunity to fly back to the CIG, I will work with Thomas Auer and his team exploring evolutionary adaptations in the gustatory systems of closely related Drosophila species.


Welcome to Sébastien!

My name is Sébastien Chamois and I recently arrived in Lausanne after eight years as a student at Sorbonne University in Paris.

During these years, I developed a high interest for the study of gene expression and RNA regulation that motivated me to obtain a master’s degree in Molecular and Cellular Biology. I then joined, for my doctoral research, Dr Lionel Benard’s group (Paris) to study the degradation of altered mRNA by a cytoplasmic surveillance pathway (No Go Decay pathway) in Saccharomyces cerevisiae.  

I discovered that the same enthusiasm towards RNA biology was shared by the Gatfield’s group that I am now grateful to join as a postdoc. At the CIG, I will study natural ribosome pausing and its importance for gene expression.
