Dr. Thanasak Lomthong graduated in Microbiology which has been a researcher at LISBP, Universite de Toulouse, INSA, Toulouse, France for 1 year. Now, Dr. Thanasak is now a lecturer at division of biology, faculty of science and technology, Rajamangala University of Technology Thanyaburi. He specialist in the field of microbial enzyme and its applications for bioenergy, bioplastic and fermentation foods. He used various technique for teaching such as PBL, STEM and also Finland model for higher education. In his work, he passed the training and test for the certificate of council of science and technology professionals in microbiology for cultivation of pathogens since 2017.
