Curriculum Vitae

Research Group

Dr. Sarawut Cheunkar is a lecturer of the Division of Biotechnology, School of Bioresources and Technology, King Mongkut’s University of Technology Thonburi. Dr. Sarawut Cheunkar received his B.S. in Chemistry from Mahidol University, Thailand and earned his Ph.D. in Chemistry from the Pennsylvania State University, United States under Royal Thai government support. His past research was focused on nanoscience and nanotechnology in which he carried out his dissertation research under the supervision of Professors Andrews and Paul S. Weiss at the California NanoSystems Institute at UCLA. There, he employed self-assembled monolayer techniques to develop neurotransmitter-functionalized surface chemistries. Using quartz crystal microgravimetry, Dr. Cheunkar investigated real-time binding behavior of G-protein coupled receptors. He also used his expertise in atomic force microscopy to characterize molecular recognition via chemical patterning techniques, including chemical lift-off lithography.
