During this period he likewise pioneered the performance of numerous advanced oncological operations both laparoscopically and robotically.
Throughout his professional career he has worked actively in the management of gynaecological cancers and premalignant conditions and their treatment in particular, as well as endometriosis, urogynaecological surgery, obstetric complications and diseases requiring complex benign gynaecological surgery; he has taken part in numerous advanced surgical procedures, clinical applications and academic activities.
