Associate Professor Dr. Ratchada Cressey, Ph.D AMS Cancer Research Unit and MT Cancer research Unit, Faculty of Associated Medical Sciences, Chiang Mai University, Thailand Associate Professor of Medical Technology in Clinical Chemistry, and Biomarkers and Molecular Biology of Cancer. Associate Professor Dr. Ratchada Cressey (Maiden name Ratchada Suaeyun) is Associate Professor of Medical Technology in Faculty of Associated Medical Sciences (AMS) at the Chiang Mai University, Thailand. Dr Cressey received her Ph.D in molecular Oncology from The Northern Institute for Cancer Research (NICR), University of Newcastle upon Tyne, UK. She completed her doctoral research on the cellular roles of MDM2 and its alternatively sliced variants. She has been a lecturer in at the division of Clinical Chemistry, AMS since 2001. Her main research area is revolved around various aspects of molecular biology of cancer i.e. genetic polymorphism and microRNA profiles toward the risk of cancer as well as the identification and characterization of a potential novel cancer biomarker.
