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.

She completed her undergraduate and Master’s degree in Biochemistry from the Université de Caen. She obtained a PhD in cell biology and neuroscience from the Université de Caen, studying the role of serine protease and cytokines in neuronal apoptotic cell death. After her PhD, she joined the Ella Bossy-Wetzel lab at the Sanford Burnham Prebys Medical Discovery Institute in La Jolla, San Diego, to study the dysfunction of mitochondrial fission in neurodegenerative diseases, with a specific focus on Huntington’s disease. She then joined the Frédéric Saudou’s lab in Institut Curie in Orsay to continue to study Huntington’s disease, this time focusing on vesicular transport defects of the BDNF receptor, TrkB. Next, she obtained an Associate Professor position at the Université Paris Saclay (previously named Université Paris Sud 11) and worked for 5 years on molecular mechanisms responsible for migration and invasion of melanocytes in aggressive uveal melanoma. Since 2016, she has joined the CEA/MIRCen to study the role of Dclk3 in Huntington’s disease, the physical interaction between LRRK2 and alpha-synuclein in Parkinson’s disease, with focus on mitochondrial and autophagy dysfunctions. In the past 2 years, she started a new project to decipher the role of a mitochondrial protein, SFXN1, in neuronal physiology and neuropathology.

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.

After successfully defending his Ph.D. thesis in August 2022, he joined the Polymenidou lab for his postdoctoral studies in September 2022. Here, he aims to understand the physiological and pathophysiological role of aggregation-prone TDP-43 and FUS proteins. In particular, he is interested in investigating the cell type-specific contributions to disease heterogeneity in order to better understand disease pathways using cellular and animal model systems. In his free time, he enjoys reading books, playing games such as chess, badminton, and cricket, and likes to travel.
