[2] At the 2016 parliamentary election, he won a seat in the Romanian Senate for Bucharest representing the National Liberal Party.
[3] Dănăilă worked for three years as a general practitioner with the sanitary district of Comănești and Dărmănești, in Bacău County.
In 1980, Dănăilă was granted a Fulbright Scholarship, enabling him to work at the neurosurgery clinic of the University Hospital of New York.
Following his travels, Dănăilă was able to perform the most complex of neurosurgical operations, including occlusion of aneurysm of the arterial vertebro-basilar system, ablation of the third ventricle tumors, surgical management of skull base tumors, carotidian and middle cerebral endarterectomy, and extra- and intracranial anastomosis.
Thus the surgical mortality rate in Bucharest fell from 50% to 2-6% for acoustic nerve neuroma and from 49% to 3% for intracerebral aneurysm cases.
