During his stay in France, Mongi Ben Hamida worked as a Clinic Chief at the Salpêtrière hospital, in the unit of Professor Raymond Garcin, then in Professor Boudin's, a great master of French neurology. Simultaneously, he joined Michel Fardeau's research program on Myopathies as a collaborator at the National Institute of Health and Medical Research. Later, he moved to New York City, where he completed a one-year internship as an associate professor at the Albert Einstein College of Medicine. Returning to Tunis in 1970, he began lecturing at the medicine school of Tunis, where he later was elected Dean. In 1974, he founded the National Institute of Neurology of Tunis where his research on Tunisian myopaths earned him international recognition. It was with his team that he discovered a rare form Duchenne myopathy, which at first raised debates on the accuracy of the results. It was only in 1992, following the discovery of the myopathy gene by Dr. Kamel Ben Othman, a member of his team, that the whole community agreed by confirming the Tunisian team's earlier conclusions. It was also the case for later discoveries, such as juvenile amyotrophic lateral sclerosis, Charcot-Marie-Tooth disease and spinocerebellar heredo-degeneracy, Friedreich's ataxia with vitamin E deficiency. All these achievements proved the unique interest that Mongi Ben Hamida held for degenerative diseases since 1976. These were pathologies that almost all neurologists of that time around the world neglected and did not care to teach at medicine schools, since according to them, these diseases were of complex classifications, incurable and their handling would result in losses to the health budget. Indeed, this represented a great obstacle for Ben Hamida during the conduction of his research, since he could not rely on the support of the local and international scientific communities, a situation which, at times, prevented him from sharing his results and articles in scientific journals. Throughout his time as Chief Physician at the Neurology Institute, he was known for his professionalism, his efforts in training his students and his exceptional behavior towards his patients. He also chaired the Arab and Pan-African Neurological Sciences Associations and is elected Vice-President of the World Federation of Neurology.
