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.

Science, Technology & Life

These are things that really have made an impact on me over the years, about science, technology, and goals we are pursing in life.


1. Seeking the Great White Bird of Absolute Truth


The following texts are excerpted from the biography of Alan G. MacDiarmid, a New-Zealand-born polymer scientist who won the Nobel Prize in Chemistry in 2000 on the discovery of conducting polymers.


I first read this piece in 2007. I still read it from time to time. Elegant and powerful, from a beautiful mind.




2. Steve Jobs' Commencement address at Stanford


Jobs delievered his speech to Stanford graduates in 2005, yet it has made a worldwide impact on students and young entrepreneurs, and perhaps for many generations to come. I, for one, found his words to be truly motivating and inspiring.


Jobs is such a talented speaker. It is better to watch his speech than just reading the texts.  Here is an alternative link to the video:




3. Mark Zuckerberg's Commencement address at Harvard


If Steve Jobs has made a good example of us trying to answer the question 'how do we live?', then Mark Zuckerberg, a talented young entreprenuer and founder of Facebook, has attempted to answer the even bigger question and perhaps the ultimate one in life: 'why do we live?'


Alternative link to the video:


What really amazed me was that Zuckerberg delivered this speech at the age of 33, in 2015. Profound, inspiring, and thought-provoking. Highly recommended.

- 曼德博,《大自然的分形几何》绪论


John Muir's words are equally important in science, especially for young students and scholars who wish to pursue their life and career in scientific research.
