Dr. Thanayod Sasivimolrattana
Asst. Prof. (Department of Microbiology, Faculty of Public Health, Mahidol University)
About me
In a world teeming with unseen wonders and complex organisms, Thanayod Sasivimolrattana, Ph.D. emerged as a passionate explorer of the microbial realm. My journey, marked by an insatiable curiosity and unyielding dedication, has led me to uncover the secrets of microbes that hold profound implications for human health. The foundations of my journey were laid at the prestigious King Mongkut’s Institute of Technology Ladkrabang, where I earned a B.Sc. in Industrial Microbiology. During this phase, my fascination with the potential of microorganisms to create impactful substances was ignited. My research at this stage focused on the screening of Streptomyces spp. strains with the capability to produce antimicrobial compounds. With a hunger for deeper insights, I pursued a M.Sc. in Medical Microbiology at Chulalongkorn University, Thailand. Here, my focus shifted to the realm of medical virology. The research took me into the intricate mechanisms of herpes simplex virus (HSV) infection in activated T lymphocytes. Undeterred by the challenges of a rigorous academic path, I earned a Ph.D. in Medical Microbiology (International Program) from the same esteemed institution. My research evolved into a comprehensive exploration of the human papillomavirus (HPV) and its intricate association with cervical cancer. There were two parts of my doctoral work: the research unraveled the multifaceted role of the microbiome (Bacteriome, Mycobiome, and Virome) in HPV-related cervical cancer while dissecting the functions of the pivotal HPV16 E1 protein in cervical carcinogenesis. These groundbreaking insights contributed significantly to our understanding of the factors underpinning this complex and devastating disease. My journey transcends academia, extending into a dynamic and impactful professional realm. Currently a lecturer in the Department of Microbiology at the Faculty of Public Health, Mahidol University, my expertise spans an array of many research areas, including anti-viral drug screening, cell-based evaluation of novel anticancer drug screening, molecular mechanisms of viral infection, and cancer development, as well as the exploration of bacteriome, mycobiome, and virome in diverse settings.
