Personal EDI statement
“I am fully committed to promoting equity, diversity, and inclusion (EDI) in my research program at University of Calgary. A harmonized blend of individuals with diverse personal experience and knowledge, cultural and language background, gender, religion, ethnicity, physical and invisible disability, gender identity, and sexual orientation should be established as a norm in all modern societies. Age, immigration status, parental responsibility, education, and economic status also should be considered and accommodated in our society. Regardless of varying status and condition of an individual, equal opportunities and rewards will be given to all research personnel to keep their personal integrity and to fully realize their research potential and career success without restrictions. As a biologist and history-lover, from time to time, I also sense that EDI is not hard-inscribed in human society. Therefore, the core values of EDI are something we should consciously recognize and promote at the expense of energy; otherwise, the value and importance of EDI can be forgotten and erased in our society. Beyond the awareness of EDI, I strive to create a research environment which deeply respects and wisely harnesses the power of EDI for innovative and collaborative research that benefit every member in my group and eventually our society.”
Research activities
My research focuses on metabolic and chemical biology in plants and microbes. Our society is heavily dependent on the cost-effective and sustainable supplies of pharmaceuticals, nutraceuticals, industrial chemicals, and bio-fuels, derived from various plants and microbes. In-depth understanding of their biosynthesis and regulation in native hosts, together with synthetic metabolic redesign in heterologous organisms, can allow us to produce a diverse array of chemicals for human health and industrial uses. However, biosynthetic mechanism and metabolic regulation of many naturally occurring chemicals are still not fully understood. We use interdisciplinary and integrative research approaches, such as molecular genetics, biochemical, cell biological, and genomics tools, to advance our knowledge of metabolic and chemical biology in plants and microbes.
Specific research activities in my lab are as follows.
- Chemical diversity and evolution of sesquiterpene lactone in lettuce, sunflower, and related Asteraceae (Compositae) plants.
- Natural rubber biosynthesis in lettuce (Latuca sativa)
- Comparative genomics of proanthcyanidin biosynthesis in pea (Pisum sativum) and Arabidopsis.
- Functional transcriptomics of medicinal plants and implementation of synthetic metabolism in microbe and plant by various biotechnological tools.
