Biography

I am the Principal Investigator (PI) of the Environmental and Public Health Group and a Professor with a 'Young Talent Tier A' appointment at Xi'an Jiaotong University (XJTU), member of the C9 league universities in China, which is ranked among the top 10 in science and engineering in the country. 

 

The overall theme of my research is on emerging contaminants and public health, and much of my previous work was on the migration of trace organic compounds into and out of polymers including membranes, plastics, and elastomers. I have a strong interest in advancing public health including exposure identification, risk assessment, mitigation, and science communication to the public. 

 

Prior to joining XJTU, I received research training and experience from the University of Auckland (UoA), National University of Singapore (NUS), University of Illinois at Urbana Champaign (UIUC), and University of Massachusetts Amherst (UMass Amherst), and worked with the PIs of several world-renowned laboratories in my fields. Since my Auckland times, I have supervised about 30 students, including several undergraduates and Master's students who later developed strong interests in scientific research and pursued PhDs. To date, I have delivered several research projects as the PI with about 3.5 million yuan in funding. I have a strong passion in scientific writing, editing, and communication. I hold appointments as the editorial board member of two scholarly journals and serve as a member of the Council of Science Editors and the China Editology Society of Science Periodicals.

On COVID-19

To our fellow researchers, students, and prospective collaborators:​​​​​

 

I have always been working on emerging contaminants since the beginning of my PhD, and this virus, out of all the things I know, is the most dangerous ‘emerging contaminant’ threatening public health. I couldn't help but often staring at the rolling numbers and statistics thinking how many people are dying from this disease every day, every hour, and every moment, somewhere in this world. And we don't even know where it came from and how it got to this far.

 

I was born in the 80s, and have been through the 1998 flood, 2003 SARS, the Christchurch earthquake, etc. This is nothing like what I have seen. 

 

Since the beginning of my research career, I have been an experimental scientist. Every single project I did was an experimental study. I believe in science, and even more so in data. But now, I have a strong will to contribute, through commentaries, critical reviews, data analyses, new ideas, to voice our concerns and share our thoughts that could be useful to others in this pandemic. To me, the goal of saving lives through research has never been so real, and so urgent. If this doesn't motivate us, I don't know what will.

 

Medical researchers are racing against time, and so are we. The rolling numbers and daily mortality counts make us think that getting our best work out in a timely fashion is the most important thing for us to contribute on COVID-19. We have a dedicated 10-person team led by myself working day and night to ensure timely delivery and the scientific rigor of our work.

 

Viruses and pandemics are an essential part of the evolution process. Being the most intelligent species living on this planet, we humans have enjoyed far too many privileges by exploiting natural resources and other living species on this planet, for far too long. There is a time we must stop and think about how we could do better, live better, and get along better with other species living on earth, our only home. For now, there is nothing as urgent as understanding the origin, infection, and transmission of this virus in our communities, and for that we must stand together, research, and communicate using science as our most powerful tool to protect more people from dying from this pandemic.

 

We invite you to come back for further updates on our work. We update this page every 1-2 weeks to ensure the latest information is published here.

Authors' note: Where did SARS-CoV-2 come from? Did it spread to the 'Patient Zero' through proactive human-animal contact (wildlife trades, hunting, bushmeat consumption, etc.)? Why did humans witness an increasing number of zoonotic diseases in the past few decades? Our article proposes a new hypothesis that differs from the "market hypothesis" in current literature.

【更新】On 29 January 2021, Nature published a Feature article (https://www.nature.com/articles/d41586-021-00251-4) where the author combed through existing evidence on fomite transmission of COVID-19 and raised questions over the cleaning and disinfection protocols that have been widely put in place in response to COVID-19. On the same day, two Australian scientists wrote a Letter to Science (https://science.sciencemag.org/content/371/6528/474.1.full) expressing concerns over the surging use of antimicrobials including disinfectants, sanitizers, and antiseptics during COVID-19, and warned on the potential of disinfectant-facilitated bacterial acquisition of antimicrobial resistance, a widely acknowledged environmental and public health risk. Our article, which was written on 7 December 2020 and currently under peer review, presents the first systematic view and in-depth analysis on this subject in the current literature context, by focusing on the chemical disinfecting agents currently approved for COVID-19 disinfection.

美国德特里克堡(Fort Detrick)生物实验室最近发表的一项follow-up study 中,引用并验证了本文的结论。作者用SARS-CoV-2真病毒,模拟阳光下车内密闭升温环境(气温54.5摄氏度、相对湿度20%、304不锈钢表面,3组重复),观察到新冠病毒在36分钟 (+/- 9分钟) 后,灭活率达到90%。

 

A follow-up study conducted at BNBI at Fort Detrick, United States, cited our findings and validated our conclusions in this paper. Authors used real SARS-CoV-2 isolates in their experiments simulating conditions in cabins of enclosed vehicles parked under direct sunlight  after a short period of time (i.e., 54.5 deg C, relative humidity 20%, on 304 stainless steel surfaces, in triplicate). The authors observed a 90% decrease in virus infectivity after 36 min (+/- 9 min). The results aligned well with our recommendation (20-30 min) based on our field measurements and data drawn on the thermal stability of SARS-CoV-2 available then.
