Professor Zhang Yin is the Presidential Chair Professor of the Chinese University of Hong Kong, Shenzhen. He is also a tenured professor in the department of computing and applied mathematics at Rice University, where he is currently on leave. Professor Zhang graduated from Chongqing University with a bachelor's degree and from The State University of New York at Stony Brook with a doctoral degree.
Professor Zhang Yin's main research areas are optimization algorithm design, analysis, implementation, as well as various practical applications and corresponding computer software development. Two examples may show his academic achievements. First, one of the most important advances in the field of optimization algorithms in the last thirty years is the study of interior point method. This method has become the most reliable and accurate algorithm to solve the general convex optimization problem. Professor Zhang has made a series of world-leading works in the research of inner point method, including the first inner point method super linear convergence velocity theory and the non-feasible point iterative convergence theory and other major theoretical breakthroughs. On the other hand, LIPSOL, the linear programming software he designed and developed, was selected as the official software by MATLAB, the most authoritative scientific and engineering computing platform, and the copyright was purchased, which was widely used by thousands of MATLAB users around the world for a long time. Second, for more than a decade, the team led by Professor Zhang Yin has made world-leading achievements in image and signal processing algorithms and data compressed sensing algorithms, among which the number of citations of the three most influential papers has reached an average of over 1,000 times in 2017.
The most successful example of Professor Zhang's application of optimization in practice came in collaboration with NASA's optimal spin path for spacecraft. Thrust-free rotation of spacecraft is the optimal attitude and trajectory for spacecraft rotation control without the use of fuel thrusters. Under the guidance of Professor Zhang and his collaborators, Professor Zhang’s students successfully solved the calculation of the optimal control trajectory, enabling propeller-free rotations on the International Space Station twice in 2006 and 2007. These propeller-free rotations have saved the cost of transporting fuel to the International Space Station, with estimated economic benefits in millions of dollars.
Professor Zhang Yin has published more than 80 academic papers in top international peer-reviewed journals, and has won numerous best papers award from relevant associations and journals at home and abroad. He is invited to deliver hundreds of reports at academic conferences or academic research institutions. Since the 1990s, Professor Zhang's research projects have received millions of dollars in grants from the US National Science Foundation and other government and nongovernmental organizations. Professor Zhang has supervised nearly 30 master's and doctoral students and postdocs. At Rice University, he was the first professor to receive the Presidential Award for Outstanding Supervisor.
