As part of the Sesquicentennial celebrations, St. Xavier’s College in association with Creighton University, USA organized an International Science Conference at its premises from 9th-11th January 2019. The interdisciplinary approach of this conference saw the gathering of eminent scientists of international repute from the field of Medicine, Pharmaceutical Industry, Biological Sciences, Chemical Sciences, and other applied Sciences; working in prestigious institutes, under one umbrella, holding panel discussions, and presenting papers as well as posters. A unique feature of this conference was the ‘Home Coming’ of the Alumni, who were ecstatic to connect with their college once again.

The XAC core committee actively participated in organising the International Science Conference held at St. Xavier's College, Mumbai.
