Lab Manager
Originally I am a fashion constructor and studied design at the University Burg Giebichenstein in Germany, a University in Bauhaus tradition.
After I gave birth to my son Noah, I changed careers and came to Bern to study molecular biology.
I am an enthusiastic organizer and as a laboratory manager I can benefit from both professions.
I love to organize for you.
I live in beautiful Bern with my son, two cats and many fish. In my spare time I like to do creative, handicraft things like making beaded jewelry. And I love the wildlife of Africa and to experience it on a safari.

Biosafety Officer & Head of Cell Culture
Our state of the art Cell culture lab is my kingdom. I love to share my knowhow and experience about cell culturing.
With great interest and joy I work with our Post doc Andrea Eberle on her research of UPF1 and it’s role in the nucleus.
I train laboratory technician apprentices during their education in our lab and biochemistry students in their BCII practical course.
As the biosafety officer of the DCBP I’m the contact person for your biosafety permissions, questions concerning biosafety and waste management.
I appreciate our good team spirit and being part of our international researcher team.

Jonas Luginbühl
Jonas Luginbühl
Technician
My interest in RNA biology started out with a bachelor thesis at the Mühlemann group in 2018, working on translation-competent cell lysates and continued through my Master thesis work, a project focused on elucidating the role of the small RNA-binding Argonaute Proteins in T. Brucei in a collaboration of the I. Roditi and M. Nowacki research groups (2018 – 2020). After a two year stay as quality control scientist in the biochemistry lab of the biopharma unit of Lonza in Visp, I rejoined academia to work in the new group of Evan Karousis (hosted by Oliver Mühlemann). My focus is Nsp1, one the first viral proteins expressed upon infection with corona viruses, and how it impacts translation in human host cells.
To balance out the logical side of science, I nurture my creativity by acting in an amateur theater group.

Evan Karousis
Junior Group Leader & Lecturer
From Piraeus, Greece
I am an mRNA biology enthusiast with expertise in mRNA stability and translation and a devoted lecturer. I developed an in vitro human translation system, which I employed to address Nonsense-mediated mRNA decay (NMD). More recently, in collaboration with the research group of Nenad Ban in ETH Zurich, I work on the impact of SARS-CoV-2 Nsp1, one of the first viral proteins that are expressed upon infection, on human translation. I also implement long-read sequencing (Nanopore sequencing) to identify endogenous mRNAs that are sensitive to nonsense-mediated mRNA decay.
I enjoy joining research forces with enthused younger colleagues, traveling, fitness, and playing the classical piano.

Sofia Nasif
Research Assistant & Lecturer
From Buenos Aires, Argentina
I`m a committed molecular biologist and my main scientific interests lie in the field of gene expression regulation, especially at the transcriptional and post-transcriptional levels. During my PhD I studied the transcriptional regulation of the hypothalamic expression of genes involved in food intake, using mouse models. After getting my PhD in Buenos Aires, I moved to Bern to study the biological impact of the mRNA decay pathway termed Nonsense-mediated mRNA decay (NMD). In particular, I am interested in understanding the roles of NMD factors in tumorigenesis and stem cell pluripotency and differentiation.

I am investigating translation termination to discover the mechanism by which regular translation termination is distinguished from aberrant/NMD-inducing translation termination. Furthermore, I`m interested in the influence of poly(A)-tail associated proteins on translation.

Post Doctoral Fellow
"I began my postdoctoral journey at the lab of Oliver Mühlemann, where I transitioned from my prior research. In my new role, I am actively contributing to ongoing projects led by PhD students. My initial exposure to mRNA biology, which occurred during my time as a student, has kindled my passion for this field. Now, as a postdoc, my focus is on supporting and assisting my colleagues in their research endeavors, leveraging my knowledge and skills. I look forward to making valuable contributions to our collective efforts."

Andrew Cowton
Post Doctoral Fellow
I am a molecular biologist with interest and experience in understanding a broad range of cellular processes and related pathologies. I completed my PhD at the University of St Andrews in Scotland, where I purified and characterised DNA polymerase complexes from the eukaryotic parasite Trypanosoma brucei. After my PhD I moved to Bern and continued working with T. brucei as a model organism to study enzymes required for GPI-anchoring of proteins. I have now switched my focus to human cells, in which I am investigating the composition and function of recently re-discovered hnRNP “ribonucleosome” complexes. Outside of the lab I can usually be found exploring Switzerland’s many mountains, lakes, and rivers, often displaying my lack of balance on a snowboard or paddle board.

I started my Ph.D. in the lab of Oliver Mühleman in 2022 after working as a research assistant at the laboratory of the Molecular Virology University of Virginia, where I studied nuclear-cytoplasmic trafficking of the Nucleocapsid protein of SARS-CoV-2. Currently, my project concentrates on the topic of translation termination in eukaryotes.
In my spare time, I love playing tennis, working out, and binge-watching Netflix.

I am from India, where I did my Bachelor’s in Microbiology from Scottish Church College, Kolkata, and Master’s in Biotechnology from Pondicherry University. I got selected into NCCR pre-doc program 2021 in Switzerland and did three lab rotations in the Muehlemann group (Bern), Sendoel group (Zurich) and Gatfield group (Lausanne), after which I decided to join the Muehlemann group for my doctoral studies from April 2023 where I am interested in the role of PABP (Poly A tail binding protein) in eukaryotic translation termination.
I love cooking a lot and try making new dishes every time. I also do gardening, hiking and play chess, and I am crazy for football as well.

PHD Student
Originally from Greece, I have a deep passion for exploring the complexities of RNA biology. I obtained my Bachelor's degree in Biology from the University of Bonn and continued my studies at the University of Cologne, where I obtained my Master's degree in Biological Sciences. It was during this time that I became fascinated by the intricate functions of RNA molecules in the mechanisms of life. This fascination led me to pursue a PhD in the Mühlemann lab.
Outside of my academic pursuits, I enjoy teaching Byzantine music and indulging in interests such as football, cooking and travelling.

My Master project is based on the Bachelor thesis work of Anika John and me and I did not hesitate to take the opportunity to stay in the lab due the welcoming and familiar atmosphere in the nonsense group. My project aims to solve the structure of SMG6 (an NMD factor and endonuclease) associated with ribosomes. Besides working in the lab, I work 40% in a MedTech consulting company in Biel.
If I am not working, I am passionate in trying out different kinds of fitness programms similar to crossfit to push myself to the limits.
