Current interests

Mike O'Connell joined NPL in 2012 to work on electrochemical imaging in catalytic systems at the nanoscale.


Mike gained a MChem from the University of Warwick in 2008, working on fabrication of carbon nanotube atomic force microscopy probes for his Masters thesis. He continued his studies at Warwick earning a PhD in 2012, having worked on developing electrochemical scanned probe microscopy and interfacial spectroscopy methods to study processes relevant to the agrochemical industry.

At NPL, Mike has worked on hybrid scanning electrochemical-scanning ion conductance microscopy (SECM-SICM) to map catalytic reactions at individual nanoparticles. Currently he is working on new techniques for characterisation of catalytic surfaces by combining electrochemistry with AFM and Raman spectroscopy.
