Dec 2 (Reuters) - Wall Street giant JPMorgan Chase's ( JPM ) global chair of investment

banking relationships around the world.

"Jennifer has lent her perspective and expertise to companies and executives at the

forefront of technological innovation and development," the memo showed.

Nason, who joined the bank in 1986, began her career in Melbourne, Australia, as a corporate

finance trainee on the Metals and Mining M&A team.
