Faculty of Science & Technology

OverviewResearch Team

As Cambodia is becoming more technologically advanced and research focused there is an increased need for professionals with a practical and solid scientific background who are able to provide research support in a variety of fields including chemical, pharmaceutical, food industry, cosmetics, environmental biology, agriculture, forensics, bioscience, microbiology, tissue culture sustainability policy, etc. Therefore, the Science Research Department of University Puthisastra is playing an active role in supporting the STI roadmap, by aligning its curriculum to the STI Roadmap, whilst also promoting and engaging in STEM research that is supported by the Cambodian government. By including the STI roadmap aims into the curriculum, Cambodian universities can offer exciting and modern degrees that will provide Cambodian graduates with a whole new range of study and employment opportunities in science fields both in Cambodia and internationally, whilst supporting the country to meet their STI Roadmap goals and creating the science and technology leaders of tomorrow.

The UP faculty of Science and Technology, especially in science research program has a wide range:

  • Biotechnology
  • Chemistry (Analytical, organic and inorganic chemistry)
  • Food (Food processing, food testing and analysis)
  • Environmental (Soil, air and wastewater)
