Bio
Xinyi Wang
Chen is talented in applied math field. He has a strong sense in computational/numerical/analytical math. Solving a hard open problem in compressive sensing area in less than one month and publishing these influential results in a famous journal are enough to prove this. With his persistent personality, I believe he is able to be competent in R&D positions and make some surprising results.
