Roger Ianjamasimanana studied Physics in Madagascar before moving to South Africa to study Astronomy. He was part of a few students who received a bursary to study Radio Astronomy as part of the Human Capital Development program of the South Africa Square Kilometer Array project. He obtained his Ph.D. in Astronomy in 2014, with a thesis that focused on high-precision measurement of fundamental parameters of galaxies. After getting his Ph.D., he spent a year at the University of South Africa as a postdoctoral fellow. He then moved to the Max Planck Institute for Astronomy in Germany as a Georg Forster fellow, a research fellowship sponsored by the Alexander von Humboldt Foundation.
Now, Roger Ianjamasimanana is a postdoctoral fellow at Rhodes University, Department of Physics and Electronics, Radio Astronomy Techniques and Technologies (RATT) in South Africa. He is using one of the most powerful radio telescope in the world (MeerKAT) to study the gas content of nearby galaxies.
