Andrian is a bioinformatician who is co-supervised by Florian and by John Marioni from the EMBL-European Bioinformatics Institute (EBI) and Cancer Research UK (CRUK). He hails from Sydney where he double-majored in molecular biology and genetics, as well as computer science, enabling him to move freely between the “wet” and “dry” worlds of biology and bioinformatics. During his PhD studies at the Victor Chang Cardiac Research Institute in the University of New South Wales, Andrian developed multiple computational tools for analysing bulk and single-cell RNA transcriptomic data. He is currently supported by a EBPOD fellowship to study single-cell gene expression in hypothalamic neurons. When he is not working, Andrian enjoys cooking and exploring the restaurant scene in Cambridge, though COVID has put a cramp in this hobby.

Crisy earned her bachelor’s degree in animal management and joined the Wellcome Sanger institute in 2014 as an animal technician. In 2018 she expanded her skill set to specialise in in-vivo phenotyping, experimental design, behavioural phenotyping, and data extraction. In her spare time, she enjoys caring for her ponies and talking her dogs for walks.

Cortina double-majored in biomedical science and developmental biology at the University of Queensland, Australia before pursuing her PhD there in the laboratories of Prof. Nickolas Lavidis and Prof. Conrad Sernia. Her work focused on the effects of physical stress on the molecular stresses experienced by neurons in the brain, and their link to neurodegeneration. After authoring 5 papers as first author during this time and receiving numerous awards, she undertook a postdoctoral position in the Woodruff laboratory investigating the underlying neuroinflammatory pathogenesis of dipeptide repeat proteins. Her other research aims to examine how stress can also potentiate neuroinflammatory priming. Cortina is now studying the time course of diet-induced neuroinflammation to reveal the cellular and molecular mechanisms leading to neuronal stress and damage.

Diego is interested in understanding the genetic causes of neurodegeneration. He studied medicine at the University of Cordoba, Argentina and obtained a PhD in Biochemistry (University of Cordoba, Argentina) in developmental neurobiology where he studied the kinesin-related proteins role in neuronal polarity. Since then he held postdoctoral positions at Cornell University, the Weizmann Institute of Science, and the MRC Toxicology Unit-Leicester/University of Cambridge where he studied polarised membrane trafficking, lipid-transfer proteins in vesicular and non-vesicular trafficking, and cold-induced structural synaptic plasticity in neurodegeneration in vitro cell types and in in vivo mouse models. In particular, he helped discover the neuroprotective role of hypothermia-induced proteins (RBM3, RTN3) in different neurodegenerative models in vivo,and demonstrated their therapeutic potential. He recently joined the groups of Andrew Bassett (WT-Sanger institute) and Florian Merkle (University of Cambridge) to design and developed phenotypic assays to complement single cell sequencing in CRISPR screens for neurodegenerative disease in different hiPSC-derived cells, including neurons, astrocytes, and microglia. 

Ed studied Pharmacology and Physiology at Manchester before embarking on his PhD at Imperial College London where he was co-supervised by Prof. William Wisden and Prof. Nicholas P Franks. During his graduate studies and a short postdoctoral stint in the same laboratories, Ed used genetic and stereotaxic viral techniques to dissect the neural circuitry in the hypothalamus regulating sleep and body temperature. He also identified likely mechanisms of action of several sleep-inducing drugs, and has been awarded numerous awards for teaching and presentation. Armed with this technical and intellectual expertise, Ed will test how certain anti-obesity drugs are neuroprotective and how genes that perturb the function of hypothalamic neurons in vitro affect food intake and body weight in vivo. His work is funded by the Chan Zuckerberg Initiative.

Eugene studied Biological Sciences at Nanyang Technological University, Singapore before embarking on his PhD at the Cancer Research UK Cambridge Institute where he was supervised by Prof. Gregory Hannon. During his graduate studies and a short postdoctoral stint in the same laboratories, Eugene used genetic and molecular biology techniques to investigate the role of long noncoding RNA during Drosophila embryogenesis. After his PhD, Eugene worked as the deputy shift lead at the Cambridge Covid-19 testing centre where he supervised staff in several laboratory settings to ensure that productivity and quality assurance targets were met. Eugene is now the laboratory coordinator for the Merkle lab where he plays an essential role ensuring its smooth operation.

Florian is a New York Stem Cell Foundation – Robertson Investigator, Sir Henry Dale Fellow (Wellcome Trust and Royal Society), and Ben Barres Early Career Investigator (Chan Zuckerberg Initiative). He majored in biology with a concentration in neuroscience from Caltech before moving to UCSF for graduate school where his work in the laboratory of Prof. Arturo Alvarez-Buylla uncovered the origin and diversity of adult neural stem cells in the mouse brain. He then worked with Prof. Kevin Eggan and Prof. Alex Schier at Harvard University and the Broad Institute of MIT and Harvard as a postdoc to develop hypothalamic differentiation protocols, adapt CRISPR/Cas9 for use in human pluripotent stem cells (hPSCs), and study the genetic architecture of hPSCs. This experience forms the basis of the Merkle laboratory’s efforts to use hPSC-derived cellular models to uncover the mechanistic basis of obesity and neurodegenerative diseases in order to develop new treatments. He is also passionate about mentoring and training the next generation of scientists. In his spare time, he enjoys cooking, gardening, running, Kung Fu, and scuba diving (when he can).

Natasha is interested in animal behaviour, which she earned her BSc in at Anglia Ruskin University. She then joined Cambridge’s University Biomedical Services (UBS) as an Animal Technician, with a specialisation in Surgery. During Natasha’s time at UBS, she obtained a good knowledge of in-vivo techniques, tissues collection and welfare. In the Merkle Lab, Natasha is gaining valuable experience on working on the ‘other side’ of the experiments, to see the biological outcomes of the animal work she helps enable. She enjoys learning new skills and in her free time she enjoys attending Tae-Kwon-Do, hiking/walking her dog, playing games and binging TV shows. 

Simone is an enthusiastic electrophysiologist and his intrigued in studying the mechanism underling diseases caused by ion channel dysfunction.  He studied Biology at the university of Calabria and earned a Master degree in Molecular Biology at the University of Milan. Simone obtained his Ph.D. in Molecular Neuroscience under the guidance of Professor Isabel Bermudez at Oxford Brookes University. During his Ph.D. Simone combined whole-cell electrophysiology, chemical modification, and protein engineering to study the molecular basis of ligand sensitivity between nicotinic acetylcholine receptors. During his Ph.D. Simone finding led to two first-author and four co-author publications, and a one-year Early Career Research Fellowship in Molecular Neuroscience awarded by Oxford Brookes University. For his postdoc, Simone joined the laboratory of Professor Steven Sine at the Mayo Clinic where he mastered single-channel electrophysiology and studied the biophysical mechanisms of activation and modulation of the α4β2 acetylcholine receptor and its role in congenital epilepsy, leading to four first-author and three co-author publications. In Cambridge Simone is using human Pluripotent Stem Cells to determine the molecular mechanisms underling the excitability of hypothalamic neurons and in how to restore the function of these neurons in disease by selective drugs. Outside of the lab Simone enjoys playing/coaching football, fishing and reading.

Venkat is a developmental biologist who studied zoology and endocrinology at University of Madras, India. He then worked on the role of T-box4 gene in hind limb development for his PhD thesis at Cambridge in the laboratory of Sir Martin Evans as a Cambridge Commonwealth Scholar. Using in vitro and in vivo models, he then studied the role of genes involved in DNA repair and pathways leading to tumorigenesis with particular focus on the BRCA2 in the labs of Prof. Steve Jackson and Prof. Ashok Venkitaraman. He was involved in showing the mechanism of pathogenic BRCA2 mutations to defects in DNA damage repair pathways and germline heterozygosity for a pathogenic mutation of BRCA2 is sufficient to promote pancreatic ductal adenocarcinomas (PDACs) in a murine model. He is now working on human pluripotent stem cell (hPSC) based cellular therapies for Parkinson’s disease with Prof. Roger Barker under the UK regenerative medicine programme (UKRMP). He is looking at the immunogenicity of hPSC derived dopaminergic precursors, developing universal cell lines that reduces the need for immunosuppression, and selective pressures that influences the behaviour of hPSCs in vitro. He is funded by the UKRMP.

Viviana studied Biotechnology (with distinction) at University of Bologna (Italy) and then she earned a master’s degree in Molecular and Cellular Biology (with distinction) from the same university. As a part of her master’s degree, she spent a period at University of Oxford studying the role of Galectin-3 and Hippo pathway in neural fate commitment.
