     Dynasil Corporation Promotes President Steven Ruggieri
                             to CEO

          Industry Veteran Also Joins Company's Board

Watertown, Mass., November 29, 2011   Dynasil Corporation of America
(NASDAQ: DYSL), a leader in the development and manufacture of
detection, sensing and analysis technology, today announced that the
board of directors has promoted President Steven K. Ruggieri to chief
executive officer of the Company and appointed him as a director,
effective immediately.

 Ruggieri, 60, becomes the eighth member of the board.  He was named
president of Dynasil in April 2011, succeeding President and CEO
Craig T. Dunham.  Ruggieri has more than 32 years of leadership
experience in the research, defense, security and technology markets
working at Foster Miller and its successor company, Qinetiq Group
North America.  He led business operations for Qinetiq North
America's Technology Solutions Group for parent Qinetiq Group PLC, a
$2.5 billion public UK company. The Technology Solutions Group was
formed through the 2004 acquisition of Foster-Miller, an R&D and
product innovation company. Following the acquisition, under his
leadership, revenue grew from $120 million to $400 million in five years.

"During his first six months as President, Steve has demonstrated the
skills necessary to lead Dynasil as CEO and to fill a key role on the
board," said Peter Sulick, chairman of the board of directors.  "The
board is encouraged by the steps he has taken to commercialize our
technology pipeline, revamp our existing products and further
diversify our contract research business.   We look forward to
working with Steve to grow Dynasil and improve shareholder value."

"I am excited to lead Dynasil at a transformational point in the
Company's history," Ruggieri said. "We are advancing our homeland
security, biomedical, and industrial technologies toward
commercialization.  The strategic initiatives that we have
implemented over the past several months are already beginning to
yield positive results.  I look forward to continuing to work closely
with the board and the entire Dynasil team."
