Hello! My name is Kangning Diao (刁康宁), and I am currently pursuing my Ph.D. in the esteemed group of Prof. Yi Mao at Tsinghua University. My research spanning from 21 cm signal, Galactic synchrotron to weak lensing, with a particular emphasis on employing statistical methods. I am especially intrigued by high-dimensional inference techniques, gradient-based models, and validating ML-based generative models. In terms of programming, I am proficient in Python and frequently utilize packages such as JAX and PyTorch.

I’m currently working with Jakob and Uros on Microcanonical Langevine Monte Carlo, a powerful sampler especially on high dimensions. I suppose physics-based differentiable model plus powerful sampler would be the final answer for all the cosmological inference problems, while before that simulation based inference (SBI) would be a good alternative. However, the problem for SBI is the discrepancy between the model and our universe. This discrepency always exists, and we have no idea of how our ML model would behave towards this unknown bias. Thus, I’m also working with Biwei and Uros on detecting the bias between models and observation.

Outside of my academic pursuits, I have cultivated several hobbies. As a Tsinghua student, I prioritize physical fitness and actively participate in Taekwondo as a member of the university team. I dedicate an amount of time each week to exercising and maintaining a healthy lifestyle. Additionally, I have a keen interest in playing the guitar, although I still consider myself a novice. Lastly, I thoroughly enjoy cooking, particularly Chinese cuisines. If you ever have an interest in sampling some of my culinary creations, feel free to reach out to me!

On the internet, I have a keen interest in aviation and electronic games. My favorite plane is the Boeing 787, and my favorite airport is PKX. I also admire the COMAC C919 and hope it achieves great success. As a fan of JRPGs, I’m currently playing “Honkai: Star Rail” by Mihoyo, although my all-time favorite game is “Persona 5 Royal”.
