I am from Shandong Province, China and am now a post-doctoral researcher at the Kavli IPMU. My research interests include accurate galaxy shape measurements, galaxy-galaxy lensing signal measurements, and modeling of galaxy-galaxy lensing signals. I really enjoy the procedure of extracting the weak signal from very noisy data. Isn't it amazing to detect the distribution of dark matter from galaxy images and further constrain cosmology? It is like communicating with Mother Nature using multiple languages, computer language and mathematical language. For me, there is nothing more interesting than studying language and communicating with people and with Mother Nature.
