Cortina (Hsiao-Jou) Chen Ph.D.
Postdoc
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 Peretti Ph.D.
Postdoc
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.

Edward Harding Ph.D.
Postdoc
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 Seah Ph.D.
Laboratory Coordinator
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.
