Work
Institutional work
Baiada was one of the leading forces behind the reprise in mathematical studies in Modena in the postwar period. Teaching mathematical analysis in Modena from 1961,
he was director of the Institute of Mathematics of the University from the academic year 1962—63 to the 1966—67: he promoted its 1966 dedication to

at the Department of Mathematics of the University of Bologna, precisely in the Vitali fonds, two letters written by Emilio Baiada from 1966 to 1968 to the Rector of the University of Modena are conserved. The first one is a request to have the Institute in Modena named after Vitali, while the second one is a request to remedy the omission of Vitali’s name in Carlo Guido Mor’s ''Storia dell'università di Modena'' (, several editions). and was also behind the construction of the then new building for the department, which opened officially during the 1974-75 academic year. Moreover he held the direction of the direction of the
Atti del Seminario Matematico e Fisico dell'Università di Modena from 1977 up to 1983.
Research activity
He published more than 60 papers on differential equations,
