Dr. Chatphatai Moonla is a hematologist, medical academic, and researcher whose work focuses on hemostasis, thrombosis, and disorders of blood coagulation. He is affiliated with the Department of Medicine at the Faculty of Medicine, Chulalongkorn University, and King Chulalongkorn Memorial Hospital in Bangkok, Thailand. The supplied profile also describes his research appointment at the UNC Blood Research Center, University of North Carolina at Chapel Hill, North Carolina, USA.

His research interests include the relationship between hemostasis and thrombosis and red blood cell abnormalities, including sickle cell disease and trait, thalassemia, hemoglobinopathies, and other hemolytic anemias. He also studies changes in coagulation and fibrinolytic systems across a range of bleeding and thrombotic disorders. These include hemophilia, von Willebrand disease and low von Willebrand factor, bleeding of unknown cause, chronic liver disease, and cancer-associated thrombosis.

Dr. Moonla completed his Doctor of Medicine degree at Chulalongkorn University between 2003 and 2010, followed by an Internal Medicine Residency from 2013 to 2016. He then completed a Master of Science in Medicine and clinical fellowship training in Hematology between 2016 and 2018. His subsequent roles include consultant hematologist at King Chulalongkorn Memorial Hospital and an academic appointment at Chulalongkorn University. The supplied timeline records his Assistant Professor of Medicine appointment from 2022.

From 2022 to 2025, he undertook postdoctoral research in Hemostasis and Thrombosis at the UNC Blood Research Center. His academic output includes work on hemophilia care in resource-constrained settings, emicizumab prophylaxis, COVID-19 coagulopathy, vaccine immunogenicity in immunocompromised patients, and fibrinolytic activation in postpartum hemorrhage and acute obstetric coagulopathy. The source describes a publication record of nearly 40 peer-reviewed articles and meta-analyses.
