Data Reduction with Information

Welcome to Applied Statistics Laboratory (ASL) at Pusan National University (PNU).

The Applied Statistics Laboratory (응용통계연구실) was established by Professor Chanseok Park (박찬석) in the Department of Industrial Engineering at Pusan National University on March 2, 2016. The lab initially shared a room with Dr. Gyu M. Lee's lab until September 2017. Afterward, the lab relocated and was situated in Rm 10-516 (ASL Lab I) and Rm 10-517 (ASL Lab II) in Engineering Building #10 at Pusan National University. On March 22, 2022, ASL Lab I and Lab II were merged and relocated to Rm 10-526.

Professor Park's office was located in Rm 10-618, adjacent to Dr. Gyu M. Lee's, until January 2018. On January 18, 2018, he moved to a new office in Rm 10-527 of the same building.

As the director of the Applied Statistics Laboratory, Professor Park leads the applied statistics group, teaches statistics courses, and conducts various research projects in applied statistics and engineering. His areas of focus include quality and reliability engineering, competing risks models, statistical computing, solid mechanics, and more. The lab also conducts research on theoretical topics such as finite-sample properties, robustness, and minimum distance methods.

Professor Park's research and the lab members have received support from several funding sources, including the National Research Foundation (NRF) of Korea, the International Cooperation Program by the NRF and the National Natural Science Foundation of China, the Two-Year Research Grant of PNU, the CK-1 fund by the NRF, the 6th BRIDGE grant of PNU, and the PNU Grant 2015, among others.
