NEW YORK (Bloomberg) ? Robert Glauber, who retired as chairman and chief executive officer of the NASD in August, joined Peter Solomon?s New York investment bank to help guide corporate clients on financial alternatives.

Glauber, 67, will be a senior adviser to the firm. Solomon, a former Lehman Brothers Holdings Inc. vice chairman, founded the bank in 1989.

Glauber stepped down after six years of heading the NASD, the biggest regulator of US brokerage firms. He oversaw the sale of NASD?s stake in Nasdaq Stock Market Inc. and its transformation into a purely regulatory organisation. Glauber returned to teaching at Harvard University as visiting professor after leaving the NASD and has since joined the board of XL Capital.

?I?ve never done anything like this,? Glauber said. ?I haven?t been on the buy or the sell-side of Wall Street. My experience is much different, so I can bring a new perspective.?

Peter J. Solomon has advised $1.3 billion of mergers and acquisitions this year, according to data compiled by Bloomberg. Among them was the $466 million sale in May of the apparel retailer J. Jill Group Inc. to Talbots Inc. Glauber said he intends to advise companies on their strategic alternatives.
