The National Women's Council of Ireland has commended the "courage and bravery" of Aoibhinn Ní Shúilleabháin in speaking out about her experience of harassment.
Dr Ní Shúilleabháin recalled her ordeal in an interview with the Irish Times and also posted about it on Twitter.
"I don't want anyone else, student or staff, to go through the same experiences I did," she said of being harassed by a former colleague at University College Dublin, where she is an assistant professor of maths.
"I hope that speaking publicly will begin a conversation that helps address this problem in third level institutes across Ireland and helps support other victims to report their experiences."
The NWCI said Dr Ní Shúilleabháin's experience highlights the need for all third level institutes to take harassment on campus seriously.
NWCI Director Orla O'Connor said she commends Dr Ní Shúilleabháin's "courage and bravery in speaking out" about her experience.
"We now need to see urgent action by all third level institutes to ensure both staff and students can be safe on campus.
"While progress has been made in many universities and colleges in this regard in relation to students, we now need a comprehensive approach that encompasses all staff and is recognised and reinforced through the governance structures of the institutions."
UCD told the Irish Times it could not comment on individual cases but had a "zero tolerance" policy on harassment.

Minister for Higher Education Simon Harris said he had met Dr Ní Shúilleabháin to discuss her experiences.
Mr Harris thanked Dr Ní Shúilleabháin "for speaking out", and for being determined that harassment in the third-level sector - for both students and staff - is stamped out.
"This is a major priority for me and [I am] taking a range of actions to make sure we achieve this."
