In the year 1955 Prof. Satyanarayan Singh, Head, Department of Zoology, Osmania University has made a successful attempt in acquiring the building from the then Deccan Airlines and established the Malaria Research Institute in this building. The Research Scholars of Osmania University and Osmania Medical College worked here.

For some unknown reasons, this building went again into the custody of Airport Authority of India. They had established a training centre here to train the pilots and an interesting fact was that, Shri Rajiv Gandhi Former Prime Minister of India was trained here in this building as a pilot.

Once again the (Ross Memorial Society) Osmania University had taken over the possession of Ross Memorial Building from the Airport Authority of India in the year 1979.

Around 1980, there was acute shortage of funds and some kind of research, which was being conducted under the Supervision of Prof. Naryan Rao Department of Zoology, Osmania University, was about to come to a halt.

In its 30^th Meeting on 10^th September 1990, the Executive Council of the Ross Memorial Society had decided to handover itself to Osmania University.

During the centenary celebrations in the year 1997, the entire building was refurbished to its original form with the help of British Council and established a modest Ross Memorial Museum with the portraits, illustrative biography of Sir Ronald Ross and his discovery of malaria transmission.
