UCD has appointed Maciej Tarnogrodzki as first team manager to replace Collie O'Neil.
O’Neill was axed by the Students on Monday.
Tarnogrodzki steps up a similar role with UCD’s Under 19 which he has held since 2017.
UCD are sitting bottom of the SSE Airtricity League Premier Divison.
A UCD statement said: "UCD AFC are pleased to confirm the appointment of Maciej Tarnogrodzki as our new first team manager.
"Maciej who has his UEFA Pro-Licence, takes charge after being promoted from his position with our under 19s, where he has been manager since his appointment ahead of the 2017 season."
