Stephan Ryser, PhD


Stephan is a biochemist, and conducted his PhD (2002) in molecular biology with the Pr. W. Schlegel (University of Geneva). After his first postdoc (2003-07), working on the function of BARD1 isoforms in ovarian cancer (with Dr. I. Irminger-Finger, University Hospitals of Geneva); he decided to undertake a second post-doc (2008-13) with Dr. A. Moodycliffe and Pr. D. Hohl (University Hospital of Lausanne). During this time, he investigated the role of CD1d in UV-induced skin inflammation and cancer. Stephan then joined the Labidi-Galy lab in 2016 and established himself as the senior staff scientist. He was instrumental in managing the laboratory daily operations as well as contributing to the laboratory’s research and clinical trials. 


Lou Romanens, PhD

2017- 2021

Lou obtained a master degree from the faculty of Science, University of Geneva. She then went on to do her PhD with the Labidi-Galy lab, working on the impact of menopause on breast cancer in BRCA1 carriers. She has been instrumental in the optimisation of a novel technique for microdissecting fresh frozen tumour samples, resulting in the writing of a technical report. Lou also undertook a project looking into the importance of the tumour immune  microenvironment through the use of Multiplex IHC. Her work has contributed to the lab’s succesful implementation of Multiplex IHC and machine learning. Following her time with Labidi-Galy Lab, Lou Romanens was awarded the SNF grant  and has relocated to Amsterdam to work with Jos Jonker at the Netherlands Cancer Institue.


Amy Anna-Maria Olziersky, PhD


Amy did her PhD with Pr. P. Meraldi (University of Geneva) on the mechanisms of chromosome segregation during mitosis following genetic and chemical perturbations (2016-2019). As a post-doc in our lab, she worked on deriving organoids from ovarian cancer samples. She is now an accredited clinical research scientist within women’s health at Roche.



Maria Josefina Lascano Maillard, PhD


Josefina, biologist, did her PhD with Pr. J. Luban (University of Geneva, University of Massachusetts Medical School) on the role of TRIM5 in innate immune cell signaling (2009-2014). She gained experience as a post-doc in bioinformatic, programming and data mining at the Swiss Institute of Bioinformatic (SIB). In our lab, she worked on analyzing single-cell RNA-sequencing datasets. She moved to Pr E. Dermitzakis lab as a senior scientist.


Sarah Stuckelberger, MD


Sarah received her MD from the Faculty of Medicine of Geneva and started a residency in obstetrics/gynecology at the University Hospital of Lausanne. She performed a 3 months internship with Dr Labidi-Galy working on BRCA2 mutations in ovarian cancer. Currently, Sarah is completing a post-doctoral research fellowship at the University of Pennsylvania with a focus on a mouse models of high-grade serous ovarian carcinoma.


Beata Rak, MD, PhD


Beata is resident in internal medicine and a visiting PhD student from the University of Warsaw, Poland. During her 6 months’ internship in the Labidi-Galy group, Beata worked on the impact of overexpression of cyclin E on breast cancer. Beat is now finishing her PhD on endometrial carcinomas in Warsaw.
