Magdalini is Associate Professor of Biomedicine at the Department of Quantitative Biomedicine of the University of Zurich. She is fascinated by the molecular events that lead to neurodegeneration and has been studying these phenomena since 2001. Originally trained as a pharmacist in Aristotle University of Thessaloniki (Greece), she did her PhD on prion diseases in the laboratory of Adriano Aguzzi at the University Hospital of Zurich (Switzerland). As a postdoctoral fellow in the group of Don Cleveland at the University of California in San Diego (USA), she used high-throughput sequencing approaches to understand the function of TDP-43 and FUS, two RNA-binding proteins that are associated with the pathogenesis of amyotrophic lateral sclerosis (ALS) and frontotemporal dementia (FTD). She joined UZH as an SNSF Assistant Professor in 2013 and since then, her research team studies the molecular mechanisms of ALS and FTD with emphasis on the interplay between protein aggregation and RNA misregulation. Magdalini was awarded the EMBO Young Investigator Award (2018), the Georg-Friedrich Götz Prize (2015), the SNSF Professorship (2013), the HFSP Career Development Award (2013) and the NIH Pathway to Independence Award (2011). She is actively working for gender equality in academia and serves on the Gender Equality Committee of the Neuroscience Center Zurich since 2014. When not in the lab, Magdalini enjoys family time, especially with her two sons, Lennart, born in San Diego in September 2012 and Kilian, born in Zurich in 2018.

Marian was born in Trencin, Slovakia and studied Biology at the Constantine the Philosopher University in Nitra. He completed his master thesis during his Slovak Gas Industry (SPP) Foundation fellowship at the University of Copenhagen. Marian did his PhD at the Charles University in Prague and at the Institute of Animal Physiology and Genetics, where he was involved in the generation and characterization of the transgenic Huntington’s disease minipig model. During his EMBO Short-Term fellowship at the University of Aarhus, he studied the first minipig brains expressing mutant huntingtin and was also involved in the mapping of the pig telencephalon. He was a visiting graduate student at the University of California in San Diego where he focused on the development of cell and gene therapies for ALS. After defending his PhD thesis in 2013, and a short postdoctoral work at UCSD, Marian joined the Polymenidou lab in August 2014. In his postdoctoral studies, he aims to understand the relative contribution of the different pathogenic mechanisms thought to cause ALS and frontotemporal lobar degeneration (FTD) in patients with C9ORF72 hexanucleotide expansions. He also aims to identify the molecular mechanisms involved in sporadic ALS using iPSC-derived motor neurons. In his free time, he enjoys traveling and recreational basketball and biking.

Pierre is a French neuroscientist. During his Ph.D. at the Lyon Neuroscience Research Center, he studied the role of VEGF in the regulation of NMDA receptor trafficking at the synapse. After his Ph.D., Pierre did a short postdoc on deciphering cellular mechanisms involved in limbic encephalitis before starting a new position at the University of Chicago. As a postdoc in Chicago, Pierre joined Pr. Gopal Thinakaran’s team to work on the cellular biology of Alzheimer’s disease. Pierre’s project was focused on exploring the role of BIN1, the second genetic risk factor for late-onset Alzheimer’s disease. He described for the first time the physiological expression of BIN1 in the brain of human and rodents, and the association of BIN1 with amyloid deposits. Pierre also worked on the role of BIN1 at the synapse and the role of BIN1 during myelination in maturating oligodendrocytes. During his postdoc, Pierre used various animal models to explore cellular and physiological questions. In the Polymenidou group, Pierre plans to develop a new animal model to study the seeding and the proliferation of TDP-43 pathology using human-TDP-43 extracts in vivo. Such a model would bring new insights on the pathological processes involved in frontotemporal lobar degeneration (FTLD) and amyotrophic lateral sclerosis (ALS), two fatal neurodegenerative diseases for which no treatment to cure or slow down disease progression is yet available. This model will offer opportunities for testing new potential treatment(s). Outside of the lab, Pierre likes to play music, watching tv-shows, hiking, biking, swimming and traveling, and have fun.

Carlo was born in a small city close to Naples, Italy and studied Medicine at the University of Genoa where he also completed his training as a Neurologist. During his residency he assisted ALS patients and was involved in several Italian and international clinical trials exploring novel therapeutic approaches for the cure of ALS. His interest in ALS investigation was not limited to a clinical approach. He was attracted by the prion and prion-like paradigm, proposed as a unifying pathogenetic mechanism for many neurodegenerative disorders, including ALS. He was interested in studying the prion-like features of TDP-43, a key player involved in ALS. With this aim, during his residency he joined the lab of Dr. Fabio Moda at Istituto Carlo Besta in Milan, to collect experimental data on TDP-43 in vitro aggregation. During this internship he acquired expertise in the in vitro amplification of prion and prion-like species by means of two powerful and innovative techniques, namely the protein misfolding cyclic amplification (PMCA) and the real time quaking induced conversion reaction (RT-QuIC). After his specialization he performed PhD thesis in the Prion Biology lab of Prof. Giuseppe Legname at the International School for Advanced Studies (SISSA) in Trieste. The aim of his PhD project was to apply the RT-QuIC technology, already developed and standardized for prion detection, to TDP-43. During his PhD, he established an RT-QuIC assay for the detection of TDP-43 aggregates in the cerebrospinal fluid of patients affected by ALS and FTD. His work provided proof of concept that the RT-QuIC technology, is feasible also for TDP-43-related disorders and can be a powerful early diagnostic tool. He joined the Polymenidou lab in August 2021 as a postdoctoral fellow. In his postdoctoral studies he aims to develop novel therapeutic agents for ALS, focusing on stabilizing TDP-43 physiological oligomerization, while counteracting its pathological aggregation. He is also interested in further developing and optimizing TDP-43 in vitro aggregation assays and to exploit them to further elucidate TDP-43 pathology. During his free time, he enjoys sports (running, beach volley, biking, climbing), reading, watching movies and spending time with his friends.
