M o n t h (1) :
Chose the weeks you want and contact [email protected] | If there will be interest in that,
I may deliver these lectures directly to universities, departments,
clinics, hospitals, etc., since I am very interested in testing this
kind of lecturing-system. You are welcome to contact me.
|
I
am also opened to support assistants who may be interested in delivering
these lectures under my supervision.
