He Jianhua is a professor at the School of Astronomy and Space Science, Nanjing University. He earned his Bachelor's degree in Physics from Shanghai Jiao Tong University in 2006, followed by a Ph.D. in Theoretical Physics from Fudan University in 2011. Between 2011 and 2015, he conducted postdoctoral research at the National Institute for Astrophysics (INAF) in Italy. From 2015 to 2018, he was awarded the International Junior Research Fellowship by Durham University in the UK, where he worked on research projects at the Institute for Computational Cosmology (ICC). In December 2018, Professor He joined the faculty of the School of Astronomy and Space Science at Nanjing University. His research expertise spans modified gravity, cosmic microwave background radiation, numerical simulations of large-scale structure formation in the universe, and observations from large-scale galaxy surveys. Currently, his research focuses on gravitational waves, numerical relativity, and the experimental detection of dark energy. To date, Professor He has published many papers in leading journals as the first or corresponding author, including Nature Physics, Nature Astronomy (with his work featured on the cover of the December 2018 issue), and Physical Review Letters.On cosmological scales, a mysterious component with positive energy but negative, repulsive pressure constitutes the bulk of the Universe, driving its accelerated expansion. This exotic substance is known as dark energy. However, understanding the true nature of dark energy remains one of the most profound challenges in modern physics. Traditionally, theories of dark energy have been tested on cosmological scales using observations such as the cosmic microwave background (CMB), baryon acoustic oscillations (BAO) and galaxy redshift distortions (RSDs). In recent years, however, ultra-precision measurements have enabled laboratory experiments to provide robust tests of dark energy as well. In this talk, I will discuss our recent experimental progress and explore potential avenues for uncovering the true nature of dark energy in the future.
