Prof. KE Ya (柯亞) is currently Professor of the School of Biomedical Sciences, the Chinese University of Hong Kong. She studied medicine and received postgraduate training in biomedical sciences research. She has a long-standing interest in deciphering the pathogenesis and functional aberrations in neurodegenerative diseases, and to explore novel therapeutic targets for these disorders. In this endeavour she also investigates the neural circuit mechanisms underlying cognitive functions and the emergence of emotions-related behaviors that could be impaired in different brain disorders including neurodegenerative diseases. To meet these challenges, a multi-disciplinary approach employing different neuroscience research tools like molecular biology, virus-based circuit mapping, opto/chemo-genetics, in vivo/in vitro electrophysiological recording, brain imaging and novel behavioral paradigms is adopted.
- Pathogenesis and treatments of neurodegenerative diseases. Neurodegenerative diseases like Parkinson’s and Alzheimer’s diseases have devastating effects on brain functions. My team tackles the etiology and pathogenesis of these disorders at multiple levels, from cells to neural circuits and brain networks. Based on our findings we also explore novel strategies that target the prevention of neurodegenerative diseases and amelioration of their symptoms.
- Neural circuit basis of cognitive functions and emotions-related behaviors. The neural circuits that mediate higher cognitive functions (e.g. learning and memory, multi-tasking ability) and emotion-related behaviors (e.g. stress-induced adaptive behaviors) are not well understood. Using cutting-edge techniques we probed the core brain areas and circuit mechanisms that mediate these functions as well as their malfunctions in neurodegenerative diseases and neuropsychiatric conditions, to pave the way for new effective therapeutic paradigms.
