Wang, Jiyong

After receiving his Ph.D. degree from China Agricultural University in Beijing, China, Dr. Wang joined Columbia University in New York City as a postdoctoral
fellow, where he studied the field of epigenetics. By transitioning to work in the clinical laboratories, he was attracted to the diagnosis of genetic
disorders by utilizing the cytogenetic and molecular methods. He specialized in developing new approaches and testing and interpreting the data for
clinical diagnostics of human diseases by leveraging next-generation sequencing and conventional Sanger sequencing analyses, as well as other molecular
methodologies. In 2020, he continued to pursue his career goal in clinical genetic medicine through the Laboratory Genetics and Genomics fellowship
at GGC. Currently, he is training in interpreting the diagnostic results of both cytogenetic and molecular tests, as well as developing novel tests
for clinical use.
