Ricci joined King's College London after completing postdoctoral research under the guidance of Prof. John Rothwell at the UCL Queen Square Institute of Neurology, University College London, and Prof. Adam Aron at the University of California San Diego. His primary research focus revolves around the development and application of brain stimulation methods for investigating the neurophysiology of the human motor system. Specifically, the work combines non-invasive brain stimulation (transcranial magnetic stimulation, TMS; transcranial direct current stimulation, tDCS) with neurophysiological methods (electromyography, EMG; electroencephalography, EEG) and behavioural assessments (movement speed and accuracy) to probe the circuits involved in human voluntary movement. Ricci's research aims to better understand human brain physiology both in healthy individuals and in those affected by neurological diseases.

Recently, he received a grant from The Academy of Medical Sciences to explore innovative TMS methodologies for investigating how antiseizure medications impact brain physiology. The overarching goal of this research is to develop predictive and monitoring tools essential for assessing treatment efficacy in individuals affected by seizures.

In addition to his research pursuits, Ricci also holds the role of a Reviewing Editor for The Journal of Physiology. Moreover, he plays an active role in academic training, having made notable contributions to book chapters within The Oxford Handbook of Transcranial Stimulation and led training workshops focused on TMS techniques.
