Bing Liu Wiki – Biography

Bing Liu was a University of Pittsburgh professor and medical researcher, who was shot and killed in an apparent murder-suicide. He was working on a cellular understanding of the virus. Liu is a Chinese-American professor of computer science who specializes in data mining, machine learning, and natural language processing. In 2002, he became a scholar at the University of Illinois at Chicago.


Bing Liu has died at the age of 37.

Bing Liu Wife, Children

Liu is survived by his wife, who was not at home during the shooting. Both of his parents lived in China, according to his department head.

COVID Researcher

Liu had been studying the cellular mechanisms of the new coronavirus. The University of Pittsburgh said Bing Liu, a research assistant professor at its computational and systems biology department, had been “on the verge of making very significant findings” into the virus before his death from multiple gunshot wounds.

The university said Liu had been part of a team modeling various biological systems in a bid to understand the cellular mechanisms of the new coronavirus, as well as the cellular basis of health complications found in Covid-19 patients. “He was patient, intelligent, and extremely mature. We will miss him very much,” it said.

“Dr Bing Liu was an outstanding researcher, who has earned the respect and appreciation of many colleagues in the field, and made unique contributions to science,” it said. “We will make an effort to complete what he started in an effort to pay homage to his scientific excellence. His loss will be felt throughout the entire scientific community.”

Academic research

He developed a mathematical model that can reveal fake advertising. Also, he teaches the course “Data Mining” during the Fall and Spring semesters at UIC. The course usually involves a project and various quizzes/examinations as grading criteria.

He is best known for his research on sentiment analysis (also called opinion mining), fake/deceptive opinion detection, and using association rules for prediction. He also made important contributions to learning from positive and unlabeled examples (or PU learning), Web data extraction, and interestingness in data mining.

Two of his research papers published in KDD-1998 and KDD-2004 received KDD Test-of-Time awards in 2014 and 2015. In 2013, he was elected chair of SIGKDD, ACM Special Interest Group on Knowledge Discovery and Data Mining.

Death and Cause

Bing Liu was found dead Saturday inside a home in Ross Township, north of Pittsburgh, the Allegheny County medical examiner said.

Investigators believe an unidentified second man, who was found dead in his car, shot and killed Liu in his home before returning to his car and taking his own life.

Police believe the men knew each other, but say there is “zero indication that there was targeting due to his (Liu) being Chinese,” according to Detective Sgt. Brian Kohlhepp.

The university issued a statement saying it is “deeply saddened by the tragic death of Bing Liu, a prolific researcher and admired colleague at Pitt. The University extends our deepest sympathies to Liu’s family, friends, and colleagues during this difficult time.”
