He completed a three year research CTN fellowship at the McGill AIDS centre in 2008 where he worked on antiretroviral drug resistance with Dr Mark Wainberg.
Dr Martinez-Cajas leads the Canada-Colombia collaboration against HIV/AIDS which is a recently developed network of Canadian and Colombian institutions devoted to research and care in HIV/AIDS. Dr Martinez-Cajas main interests are optimization of HIV treatment in resource-limited countries, appropriate use of antiretroviral drugs, improvement of antiretroviral medication adherence, prevention and management of drug resistance in HIV in resource-limited countries and better and earlier detection of HIV infection and resistance.
