Short Biosketch

Dr. Ang Guo received Ph.D. in physiology and Molecular Cardiology from Shanghai Institute for Biological Sciences, Chinese Academy of Sciences in 2010. Before joining NDSU in 2019 as an assistant professor, he conducted research as research assistant professor and postdoctoral researcher in the University of Iowa. With the funding support from American Heart Association, he laid the groundwork of several mechanisms in cardiac disease development and stress responses. The discoveries are published on top notch journals including Science and PNAS.

Dr. Ang Guo’s research centers on molecular and cellular mechanisms of cardiovascular diseases. Specifically, his lab is focusing on cardiac injury and metabolic stress response mechanisms, including 1). Crosstalk between Excitation-Contraction (E-C) coupling proteins and transcription in heart failure; 2) Exosome mediated cell signaling in cardiac diseases; 3) Crosstalk between metabolomics and epi-transcriptomic in cardiovascular diseases. He is also interested in translating mechanistic insights into novel therapies in cardiovascular disease models. His research uses multidisciplinary approaches including biochemistry, molecular cellular biology, genetics, physiology, and engineering.

Software development

Independently developed AutoTT, which is an image analysis software used for processing and analyzing structure of sarcomere and T-tubules in myocytes. More than 30 labs all over the world requested and used this software. 

Independently developed CaTeasy, which is a software used for analyzing Ca2+ signals imaged by confocal microscopy. This software is used routinely in my lab.
