Personal presentation

I was born in China and spend my childhood in a small village. After grown up I started to learn mechanical design in Wuhan University, China. The courses are quite useful, yet I would like to know something more fundamental, so I also took courses from physics department for about two years, and managed to become a master student in theoretical physics. Through three years of training, I learned the beauty of general relativity and start to wondering how to reconcile it with the principles of quantum mechanics, and how would the merge change our understanding of space and time completely. And it’s lucky for me that after finishing my master program in 2019 I got the chance to start my research in quantum gravity in Daniele’s group as a Ph.D student.
There are many areas that are interesting and important in the quantum gravity community, and in particular I’m interested in the continuum limit and observational effects of the fundamental theories. The continuum limit attracts me as in group field theory, for example, the very notion of space and time disappears and it would be quite exited to see how the macroscopic space and time we experienced every day emerged from the building blocks of the fundamental theory. On the other hand, observational effects are needed to test the theory, although it’s unlikely we can see these effects in a near future due to the weakness of gravity, the derivation of such effects itself would be interesting and may lead to new insights for our understanding of quantum gravity.
