Torsten Ochsenreiter - group leader
Torsten was trained as a microbial ecologist at the University of Darmstadt in Germany. He applied environmental genomics approaches to characterize the function of non-cultured bacteria and archaea, primarily in soil habitats. During his postdoc in the US, he became fascinated with trypanosomes and characterized functional aspects of mitochondrial RNA editing in these parasites. In 2008, he moved to Bern, Switzerland, to start his own lab and work in molecular parasitology on mitochondrial organelle biogenesis. Since 2016 Torsten has been an Associate Professor in Cell and Microbiology at the Institute of Cell Biology in Bern. In 2022 Torsten completed a CAS for Systemic Coaching and Change Management at the University of Cologne, Germany. When not in his office, classroom or lab Torsten enjoys being up in the air, flying a glider or very recently also a paraglider.
Gaëlle Lentini - ambizione fellow
Gaëlle delved in parasitology early on by studying the mechanism of host cell invasion in the human parasite Toxoplasma gondii during her PhD at the University of Montpellier (France). For her post-doc, Gaëlle scrutinized the host-pathogen interactions between Trypanosoma cruzi, the causative agent of Chagas disease and its mammalian host cell at the Harvard School of Public Health (Boston). This venture was extremely exciting and Gaëlle became passionate about T. cruzi biology. Back in Europe at the University of Geneva, she started her independent project on the mechanism of cellular abscission in T. gondii. Since September 2023, Gaëlle is a Ambizione group leader associated with the Ochsenreiter lab and investigates the cellular and molecular mechanisms of EXIT employed by T. cruzi to egress from its host cell. For out of the bench activities, Gaëlle spends her time hiking, cycling and enjoys discovering the world’s best cuisines.
Markus Gerber - lab manager
In 2024, Markus completed his PhD in the Schneider Lab at the University of Bern, where he investigated mitochondrial quality control in Trypanosoma brucei. Since March 2024, he has been working as a lab manager in our lab. In his free time, he enjoys screaming his lungs out with his band Thy Gnosis.
Sara De Grandis - PhD Student
Sara De Grandis finished her master in Experimental Biomedical Research at the University of Fribourg in June 2023, specializing in Microbiology. In December 2023, she joined Ambizione Fellow Gaëlle Lentini’s lab as a Lab Technician to investigate Trypanosoma cruzi’s exit strategy, driven by her deep fascination with pathogens. Beginning of 2025 she decided to pursue a PhD within the same lab. In her free time she loves hiking in the mountains, running and cycling.
Roman Engimann - apprentice/technician
Roman is a trainee laboratory technician who stands out for his skills and helpful nature. His excellent knowledge of geography is a great asset during the team crossword puzzles solved at lunch breaks. Beyond his passion for geography, Roman is highly competent in his lab work, performing tasks with precision and reliability, which he truly enjoys. Moreover, he supports his colleagues by taking on tasks they don’t have time for. Roman's dedication and teamwork make him a valued member of the team.
Adamantia Chantziou - PhD student
Amanda is a PhD student who joined the lab in 2023. She is interested in cell biology and wants to unravel the mechanism of mitochondrial fusion and fission in T. brucei. In her free time she enjoys reading books, painting and cinema.
Robin Eberle - PhD student
Meet Robin, a dedicated member of our team who brings a wealth of knowledge and enthusiasm to our research endeavors. Having completed his Bachelor and Master's degrees at ETH in Zurich, Robin possesses a strong academic foundation that serves as a solid base for his contributions to our projects. Beyond his academic pursuits, Robin finds solace in the great outdoors, often embarking on picturesque hikes to recharge his creativity and focus. In the realm of artistic expression, he also dedicates his free time to the enchanting melodies of the piano, a passion that beautifully complements his scientific pursuits.
Enrico Santini - PhD Student
Enrico has a strong passion for fundamental research and microscopy. His love for science and nature has led him to pursue a PhD in the University of Bern. When outside the lab he loves to go hiking, going for a good beer at a jazz bar and occasionally going to live concerts.
Delia Bogenstätter - master student
Delia joined Ambizione Fellow Gaëlle Lentini’s lab September 2024 as a master’s student. Her master thesis focuses on identifying factors secreted by Trypanosoma cruzi shortly before host cell egress, aiming to shed light on the molecular mechanisms that facilitate parasite exit from the host cell. Outside the lab, Delia enjoys spending time with friends and family, reading books, and exploring creative projects through crafting.
Silje Debets - master student
Silje, a visitor from Radboud University the Netherlands, will be completing her masters internship at the Ochsenreiter Lab investigating genes potentially involved with the mitochondrial DNA segregation machinery in Trypanosoma brucei. When not in the lab, she enjoys knitting, hiking, and exploring Switzerland in the time she's here.
