Steve Campbell

Steve was an independent affiliated senior research holding a SIRG grant at TCD in 2019 before moving to a faculty position at University College Dublin.

Hailing from north of the border, he completed his PhD at Queen's University Belfast in 2011 under the supervision of Mauro Paternostro. Steve moved to University College Cork to work with Thomas Busch in 2012 and spent 2013 at the Okinawa Institute of Science and Technology Graduate University in Japan, before returning to Belfast and Queen's University between 2014 and 2016. He was awarded a fellowship from the INFN Sezione di Milano in 2017 and worked with Bassano Vacchini. From February to September 2019 he was a Senior Research Fellow at Trinity College Dublin after being awarded an SFI Starting Investigators Research Grant for a project on Quantum Speed Limits in Thermodynamic Processes. He left to take up a permanent faculty post in the School of Physics at University College Dublin in October 2019.

Steve is interested in exploring the role which fundamental bounds, such as the quantum speed limit, play in characterising and designing thermodynamically efficient control protocols for complex quantum systems. He works on a variety of topics including open quantum systems, quantum metrology, critical spin systems and phase transitions, and coherent control.
