I am on Signal.
You can use Signal to contact me regarding any kind of inquiry.
For inquiries related to research, teaching, the lab, oTree, software and similar areas, please click here. This is my work email account and is only monitored during working hours. If you receive an out-of-office reply, read it carefully.
You can also contact me by clicking here. This email adress is preferred for personal inquiries and those that require superior security. My email server has full disk encryption and old emails are regularly removed from it.
Please use email encryption (see below). There is now a seamless way to do it without any additional software.
It is out of my control who has access to my work email account. It may be subject to “freedom of information act” requests or surveillance. However, please use my personal email address only if you have an extraordinarily good reason to do so. Use common sense.
Encrypted messages
If you wish to send me an encrypted email or message without having to use any extra software, you can use this website (Tor Onion Service) from the comfort of your web browser. It allows you to create a secure email without installing any software on your device.
The remainder is for experts:
