Dr. Liu is currently an Assistant Professor at the School of Engineering and Applied Sciences, Harvard University. He has more than 10 years of experience in nanoelectronics and bioelectronics. He has also gained in-depth biological and clinical knowledge through experience in developing a variety of tools that combine nanoelectronics, polymer chemistry, genetic engineering and tissue engineering to address challenges in neuroengineering, brain-machine interface and cardiac arrhythmia. His early research (Nature Mater, 2012, 2015 & 2016; Nature Nanotechol, 2015 & 2016; Nat Biomed Eng, 2019; Science, 2020) on “tissue-like electronics”, “gliosis-free long-term brain electronics implantation” and "genetically-targeted brain device" has established some of the fundamental principles for current state-of-the-art tissue- and brain-machine interfaces used in both academic research and industrial applications. His laboratory at Harvard University is primarily focusing on the development of new bioelectronic, cyborg engineering, genetic/genomic engineering and computational tools for biological and biomedical applications.
