Affiliated Research Scientist
After a PhD in Queen’s University Belfast in 2011 under the supervision of Mauro Paternsotro, he moved to University College Cork to work with Thomas Busch in 2012. He spent 2013 at the Okinawa Institute of Science and Technology Graduate University in Japan. Returning to Belfast, he spent 2014 through to 2016 at his alma mater Queen’s University. In 2017 he was awarded a fellowship from the INFN Sezione di Milano and worked with Bassano Vacchini. From February 2019 he has been appointed as Senior Research Fellow at Trinity College Dublin through the award of an SFI Starting Investigators Research Grant for a project on Quantum Speed Limits in Thermodynamic Processes.
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, critical spin systems and phase transitions, metrology, and coherent control.
