Thank you for contacting me. LinkedIn is generally a reasonable means of contacting me; please explain the purpose of your query in the connection request (or I will likely ignore the connection). I currently get between 5-10 queries a day and do not have time to respond to everyone. If you wish to email me, my email address is the first letter of my first name, followed by "t," followed by my last name, @ the primary domain name of the university where I teach. Sorry for the "puzzle," but it does help keep random/automated pings to a minimum.
