If you need to contact me in connection with my Warwick University employment, please visit my web site there:
If you wish to send me personal messages then I will already have informed you of the email address you should use as well as my phone number.
I am happy to receive email which is appropriately signed (and preferably encrypted), and my PGP/GPG Public Key (fingerprint: 4F33 8C0D 1570 9359 C248 9E81 1DD0 4C29 69FA 7BC3) should be used for that purpose.
I do not use social media.
