During lock-down, and maybe beyond if there is a call for it, I am now offering my talks in a virtual  environment.
For those not familiar with the process I would set up an on-line meeting room and all those participating would then be sent an invitation to join.
Alternatively, this could be done in reverse with a society's secretary or speaker finder setting up the meeting and inviting me to join once all the members are logged-on.

There is no special equipment required, you would see the presentation on your computer screen and see me inset in the bottom corner while I deliver the talk,

Whilst the applications that facilitate virtual meetings, Zoom, Hangouts etc will work on  a smart phone they are better on a computer or a large-format tablet.

If you think this might be of interest then please get in touch and we can talk through the possibilities.
