Zhi Quan (George) Zhou

Overview

Zhi Quan (George) Zhou received the BSc degree in Computer Science from Peking University, China, and the PhD degree in Software Engineering from The University of Hong Kong. His current research interest is in software testing and debugging; cybersecurity and security testing; the interplay among software testing, machine learning, and big data; and self-driving vehicles.

Zhou was a main contributor to some of the earliest research papers on metamorphic testing, and was one of the few pioneers who opened up and established this research field. In 2016, he co-founded and chaired the IEEE/ACM 1st International Workshop on Metamorphic Testing, in conjunction with the 38th International Conference on Software Engineering (ICSE MET '16) in Austin, USA. He was an invited keynote speaker at ICSE MET 2017 held in Buenos Aires, Argentina, and at the IEEE International Conference on Artificial Intelligence Testing in San Francisco, 2019 (slides), where he was also the organizer of the Special Track on Metamorphic Testing and Artificial Intelligence. He was an ACM SIGSOFT Webinar speaker, an ICSE '18 Technical Briefings speaker, and an ICSE '16 and ICSE '19 journal-first speaker, introducing metamorphic testing through all these venues. He was selected for a Virtual Earth Award by Microsoft Research, Redmond, USA, and a 2018 Researcher of the Year Gold Disruptor Award by the Australian Computer Society.

Zhou has been invited to serve as a reviewer for various organizations including the Australian Research Council, the Research Grants Council of Hong Kong, and the Air Force Office of Scientific Research of the United States Air Force, and for various international journals including IEEE Transactions on Software Engineering, on Computers, on Reliability, on Services Computing, and so on.

Exposing Hidden Defects in Citation Statistics and Journal Impact Factors
Summary
Zhou initiated a "metamorphic robustness testing" method and led his research team to use this method to verify the major citation database systems <a href="https://www.scopus.com" target="_blank" rel="noopener">Scopus</a> and <a href="https://clarivate.com/products/web-of-science/" target="_blank" rel="noopener">Web of Science</a>, revealing robustness problems in citation counts and journal impact factors computed by these systems. A paper titled "Metamorphic Robustness Testing: Exposing Hidden Defects in Citation Statistics and Journal Impact Factors" by Zhi Quan Zhou, T.H. Tse, and Matt Witheridge has been published in IEEE Transactions on Software Engineering, the top journal in the field (URL for download: <a href="https://doi.org/10.1109/TSE.2019.2915065" target="_blank" rel="noopener">https://doi.org/10.1109/TSE.2019.2915065</a>).The high impact of the results lies in the finding that the presence of simple hyphens in a paper title adversely affects the citation statistics. Thus, metrics based on citation counts, which are commonly used for staff evaluations in universities, are not as robust as widely believed. This will be of interest not only to professors seeking tenure or promotion, but also to the senior management such as presidents, deans, and heads. The surprising results are applicable to all faculties in any university. Zhou et al.'s findings have been reported by international news media, including <a href="https://documents.uow.edu.au/~zhiquan/TheHyphenMan.pdf" target="_blank" rel="noopener">The Australian</a>, <a href="https://www.psychologytoday.com/intl/blog/the-athletes-way/201906/one-small-hyphen-in-title-could-diminish-academic-success" target="_blank" rel="noopener">Psychology Today</a><a href="https://www.sciencealert.com/hyphens-break-our-entire-system-of-scientific-ranking-new-analysis-reveals" target="_blank" rel="noopener"></a>, <a href="https://cacm.acm.org/news/237400-a-single-punctuation-mark-has-been-skewing-our-entire-system-of-scientific-ranking/fulltext" target="_blank" rel="noopener">Communications of the ACM</a>, and <a href="https://www.eurekalert.org/" target="_blank" rel="noopener">EurekAlert!</a>, among others. On the Internet, the implications of Zhou et al.'s findings have been discussed from diverse perspectives, some of which extend beyond the conventional computing and citation domains. For example, see "<a href="https://www.slashgear.com/brave-new-world-predictions-are-coming-true-with-hyphens-31578773/" target="_blank" rel="noopener">Brave New World predictions are coming true with hyphens</a>" written by <a href="https://www.slashgear.com/author/chrisburns/" target="_blank" rel="noopener">Chris Burns</a> on <a href="https://www.slashgear.com/brave-new-world-predictions-are-coming-true-with-hyphens-31578773/" target="_blank" rel="noopener">SlashGear</a>. Inquiries have been made from various communities including, among others, the community of patients with <a href="https://www.3cr.org.au/chronicallychilled/episode-201901021800/asher-wolf-ehlers-danlos-syndrome" target="_blank" rel="noopener">Ehlers-Danlos Syndrome</a> (a <a href="https://en.wikipedia.org/wiki/List_of_syndromes" target="_blank" rel="noopener">condition</a> that has a hyphenated name and is known to be under-reported and under-researched).

Detected and reported fatal bugs in self-driving cars eight days before the Uber crash in March 2018
Summary
On March 10, 2018, Zhou and his MPhil student Liqun Sun detected a critical fault in the real-world self-driving system <a href="http://apollo.auto" target="_blank" rel="noopener">Baidu Apollo</a>, and they reported this finding to the Apollo team on the same day (this was 8 days before <a href="https://en.wikipedia.org/wiki/Death_of_Elaine_Herzberg" target="_blank" rel="noopener">a fatal accident of a Uber's self-driving vehicle in Tempe, Arizona</a>). The fault caused the self-driving car's LiDAR perception system to ignore pedestrians or other obstacles on the roadway. The Apollo team confirmed the fault on March 19, 2018 (24 hours after <a href="https://en.wikipedia.org/wiki/Death_of_Elaine_Herzberg" target="_blank" rel="noopener">the Uber accident</a>, where the vehicle involved used exactly the same type of LiDAR sensor as Apollo). This study was reported in an article titled "Metamorphic Testing of Driverless Cars" by Zhou and Sun, published in the <a href="http://dx.doi.org/10.1145/3241979" target="_blank" rel="noopener">Communications of the ACM</a> (ACM's flagship magazine). Zhou covered this story in his <a href="http://doi.org/10.5281/zenodo.2636979" target="_blank" rel="noopener">keynote speech</a> at the <a href="http://www.ieeeaitests.com/html/speakers.html" target="_blank" rel="noopener">IEEE International Conference on Artificial Intelligence Testing</a> (AITest 2019) held in San Francisco East Bay, California.

Exposing Hidden Defects in Citation Statistics and Journal Impact Factors
Summary
Zhou initiated a "metamorphic robustness testing" method and led his research team to use this method to verify the major citation database systems <a href="https://www.scopus.com" target="_blank" rel="noopener">Scopus</a> and <a href="https://clarivate.com/products/web-of-science/" target="_blank" rel="noopener">Web of Science</a>, revealing robustness problems in citation counts and journal impact factors computed by these systems. A paper titled "Metamorphic Robustness Testing: Exposing Hidden Defects in Citation Statistics and Journal Impact Factors" by Zhi Quan Zhou, T.H. Tse, and Matt Witheridge has been published in IEEE Transactions on Software Engineering, the top journal in the field (URL for download: <a href="https://doi.org/10.1109/TSE.2019.2915065" target="_blank" rel="noopener">https://doi.org/10.1109/TSE.2019.2915065</a>).The high impact of the results lies in the finding that the presence of simple hyphens in a paper title adversely affects the citation statistics. Thus, metrics based on citation counts, which are commonly used for staff evaluations in universities, are not as robust as widely believed. This will be of interest not only to professors seeking tenure or promotion, but also to the senior management such as presidents, deans, and heads. The surprising results are applicable to all faculties in any university. Zhou et al.'s findings have been reported by international news media, including <a href="https://documents.uow.edu.au/~zhiquan/TheHyphenMan.pdf" target="_blank" rel="noopener">The Australian</a>, <a href="https://www.psychologytoday.com/intl/blog/the-athletes-way/201906/one-small-hyphen-in-title-could-diminish-academic-success" target="_blank" rel="noopener">Psychology Today</a><a href="https://www.sciencealert.com/hyphens-break-our-entire-system-of-scientific-ranking-new-analysis-reveals" target="_blank" rel="noopener"></a>, <a href="https://cacm.acm.org/news/237400-a-single-punctuation-mark-has-been-skewing-our-entire-system-of-scientific-ranking/fulltext" target="_blank" rel="noopener">Communications of the ACM</a>, and <a href="https://www.eurekalert.org/" target="_blank" rel="noopener">EurekAlert!</a>, among others. On the Internet, the implications of Zhou et al.'s findings have been discussed from diverse perspectives, some of which extend beyond the conventional computing and citation domains. For example, see "<a href="https://www.slashgear.com/brave-new-world-predictions-are-coming-true-with-hyphens-31578773/" target="_blank" rel="noopener">Brave New World predictions are coming true with hyphens</a>" written by <a href="https://www.slashgear.com/author/chrisburns/" target="_blank" rel="noopener">Chris Burns</a> on <a href="https://www.slashgear.com/brave-new-world-predictions-are-coming-true-with-hyphens-31578773/" target="_blank" rel="noopener">SlashGear</a>. Inquiries have been made from various communities including, among others, the community of patients with <a href="https://www.3cr.org.au/chronicallychilled/episode-201901021800/asher-wolf-ehlers-danlos-syndrome" target="_blank" rel="noopener">Ehlers-Danlos Syndrome</a> (a <a href="https://en.wikipedia.org/wiki/List_of_syndromes" target="_blank" rel="noopener">condition</a> that has a hyphenated name and is known to be under-reported and under-researched).

Detected and reported fatal bugs in self-driving cars eight days before the Uber crash in March 2018
Summary
On March 10, 2018, Zhou and his MPhil student Liqun Sun detected a critical fault in the real-world self-driving system <a href="http://apollo.auto" target="_blank" rel="noopener">Baidu Apollo</a>, and they reported this finding to the Apollo team on the same day (this was 8 days before <a href="https://en.wikipedia.org/wiki/Death_of_Elaine_Herzberg" target="_blank" rel="noopener">a fatal accident of a Uber's self-driving vehicle in Tempe, Arizona</a>). The fault caused the self-driving car's LiDAR perception system to ignore pedestrians or other obstacles on the roadway. The Apollo team confirmed the fault on March 19, 2018 (24 hours after <a href="https://en.wikipedia.org/wiki/Death_of_Elaine_Herzberg" target="_blank" rel="noopener">the Uber accident</a>, where the vehicle involved used exactly the same type of LiDAR sensor as Apollo). This study was reported in an article titled "Metamorphic Testing of Driverless Cars" by Zhou and Sun, published in the <a href="http://dx.doi.org/10.1145/3241979" target="_blank" rel="noopener">Communications of the ACM</a> (ACM's flagship magazine). Zhou covered this story in his <a href="http://doi.org/10.5281/zenodo.2636979" target="_blank" rel="noopener">keynote speech</a> at the <a href="http://www.ieeeaitests.com/html/speakers.html" target="_blank" rel="noopener">IEEE International Conference on Artificial Intelligence Testing</a> (AITest 2019) held in San Francisco East Bay, California.
