Associate Professor 副教授
Peiyong Jiang is currently an associate professor and a bioinformatician at the Department of Chemical Pathology, The Chinese University of Hong Kong. He serves as Director of Biomedical Computing Centre at the Li Ka Shing Institute of Health Sciences (LiHS). He received his bachelor's degree in bioengineering from Huzhou Teachers College in 2006. During that time, he was trained in biology, biochemistry, genetics, biostatistics and programming languages. Afterward, he received his master's degree in crop genetics and breeding from Huazhong Agricultural University in 2009. During the time of pursuing a master's degree, he was mainly trained in advanced genetics, statistics, and bioinformatics. His research work involved the plant microRNA prediction in silico, particularly using machine learning algorithm to explore Next Generation Sequencing (NGS) data. Thereafter, he received his Ph.D. in Chemical Pathology from The Chinese University of Hong Kong in 2012 and had postdoctoral training at the Department of Chemical Pathology, The Chinese University of Hong Kong from 2012 to 2015. Since he joined the department, he has been working on bioinformatics. With a multidisciplinary background of genomics, bioinformatics, computational biology, and statistics, he has a long-standing research interest in NGS-based bioinformatics data analysis as well as its clinical applications such as noninvasive prenatal testing and cancer detection.
He was named the “Top 20 Translational Researchers of 2019” by the world-renowned scientific journal Nature Biotechnology in 2020. He has recently been elected a senior member of the National Academy of Inventors (NAI) (the first scholar from a Hong Kong institution to receive this senior membership).
Specialized Research Area(s):
1. Developing mathematical algorithms and bioinformatics software for the Next Generation Sequencing (NGS) data analysis
2. Developing bioinformatics algorithms for the noninvasive prenatal testing and noninvasive cancer detection
3. Field-Programmable Gate Array (FPGA) based computing acceleration for NGS-based big data analysis
