My youngest daughter Dana Dachman-Soled
finished her PhD in
computer science at Columbia University
and was a post-doc at
Microsoft Research New England in 2011 - 2013.
In the Fall of 2013 she joined the
Department of Electrical and Computer Engineering

computational learning theory, are now focused on cybersecurity
in conjunction with

Maryland Cybersecurity Center).
Among her invited talks are one
at the China Theory Week 2010 conference and more recently one at
Arizona State University.
And she taught
Cryptography Against Physical Attacks in the Fall 2013 semester,
Introduction to Cryptology in the Spring 2014 semester,
Digital Logic in the Fall 2014 semester.

New York Times .
Perhaps the IRS should reconsider the tax exempt status of a public institution that
pays its administrators an unreasonable salary.
A source of information about the IRS's role in determining tax exempt status is
