Contributions to Science Applications in Community Development
- Cofounder of a Biotech Startup, EnzMart Biotech (www.enzmart.com). The company produces and sells laboratory reagents at competitive prices to local Thai researchers.
- Cofounder of a Biotech Startup, BioSynThai Biotechnology. The company develops and operates frontier biotechnologies and process engineering to support circular economy.
Developed Synthetic Biology technology to turn food waste into valuable bioenergy and biochemicals. This technology has been rolled out on a pilot in “Zero Waste” concept to a community in Nan (province in the Northern part of Thailand). The goal is to scale and expand this technology for implementing a countrywide comprehensive and sustainable waste management program.
