2017 September - Michael Ramharter

Dr Michael Ramharter

MedUni Wien RESEARCHER OF THE MONTH, September 2017

Dr Michael Ramharter has been awarded the biannual award of the German Association for Tropical Medicine (DTG) for his work on the clinical development of drugs against poverty-related infectious diseases in Africa. Over the past decade Dr Ramharter has led several drug development trials in the field of malaria and neglected tropical diseases. Based on these studies several new antimalarial drugs were successfully evaluated by the European Medicines Agency and national regulatory authorities and are now available for local populations in endemic countries. Recently, Dr Ramharter’s team engaged in the development of innovative single dose antimalarial combination therapy and evaluated drugs for the treatment of neglected tropical diseases such as urogenital schistosomiasis and filarial infections.
