driven by the passion for higher studies Prof. Medhi went to U.K and joined the Manchester University for a MS degree in Statistics (by Thesis) where he worked under the supervision of Prof. M. S. Barlett on Time Series Analysis.
Prof. Medhi's maiden research article ‘On the efficiency of procedures for smoothing periodogram from time series with continuous spectra’ which he wrote with Prof. Barlett and which was published in Biometrica (London) in 1955 had far reaching consequences which can be seen from the tributary paper written by Prof. T. Subba Rao, the first Ph.D scholar of Prof. Medhi at Gauhati University and a former Professor Emeritus at Manchester University, UK in a special issue of Assam Statistical Review, a research journal in Statistics published by Dibrugarh University as a mark of respect to Prof. Medhi in 1991.
Prof. T. Subba Rao wrote:
“...............when I discussed with Prof. Medhi for a possible topic for research, he suggested to me then that I should look into spectral analysis of time series to which he introduced me and which was considered at that time (during 1960s) to be the most advanced and useful (with potential applications for engineering and meteorology etc.). In fact many of the chapters of my Ph.D thesis submitted to the University of Gauhati (1966) were on spectral estimation; a subject on which I am still working nearly for 50 years. I choose this topic as a tribute to Professor Medhi...............”
After completing his MS degree from Manchester University, UK, Prof. Medhi joined University of Paris for a Doctorate degree. As he was required to defend his thesis in French, Prof. Medhi had taken a diploma course in French,
