Dr. Haiyang Yu uses cutting-edge approaches in cell biology, molecular biology, and genetics to study neurodegenerative disorders such as frontotemporal dementia (FTD), Lou Gehrig’s disease (amyotrophic lateral sclerosis; ALS), and Alzheimer’s disease. He has also developed novel therapeutic strategies by specifically degrading cytoplasmic protein inclusions.

Dr. Yu grew up in Chengde, China. He received his bachelor’s degree summa cum laude in Biological Sciences from Nankai University, where he started his research in cell biology. He earned his Ph.D. in Molecular Cell Biology from Washington University in St. Louis, where he focused on how the actin cytoskeleton is regulated by Rho family small GTPases.

As a postdoctoral fellow mentored by Dr. Don Cleveland, Dr. Yu focused on TDP-43, a nuclear RNA-binding protein essential for neuronal health, which forms cytoplasmic aggregates during neurodegenerative disease. He and his colleagues found that TDP-43 de-mixes into complex liquid-crystal droplets when it loses its ability to bind RNA. These droplets, which they named anisosomes, form in neurons in vivo when proteasome activity is inhibited. For this work, he received an NIH postdoctoral fellowship (F32) and a Pathway to Independence award (K99/R00).

Dr. Yu joined the UT Southwestern faculty in 2021 as an Assistant Professor in the Center for Alzheimer’s and Neurodegenerative Diseases, with a secondary appointment in the Department of Molecular Biology. He is also an investigator in the Peter O’Donnell Jr. Brain Institute.
