Daniel obtained his BSc in Mechanical Engineering and Production Technology with a double Bachelor’s degree from Saimaa University of Applied Sciences (Finland) and Vitus Bering University College (Denmark). He then gained his MSc in Mechanical Engineering and Design from the University of Manchester in 2014. Afterwards he joined the Centre for Doctoral Training in Ultra Precision at the University of Cambridge where he graduated obtaining an MRes degree in 2015.

Daniel is currently working on Anode Materials for vacuum electronics Devices.
Metal anodes in vacuum electronics devices erode during usage, limiting the lowest achievable pressure in an vacuum electronics device reducing its efficiency. The challenges lie with the anode’s significant contribution to outgassing, predominantly of the hydrogen atoms stored in its bulk, and plasma formation, caused by the near surface ionization of the outgassed neutral atoms by the desorbed electrons or secondary electrons due to anode’s secondary electron emission – both of which are thermally driven phenomena generated by the electron beam impacting the anode’s surface.
