When Debbie Mukherjee was having down days in her last few jobs, she would try to walk around the office to cheer up.

"You're in a corporate headquarters or a manufacturing facility, and, oh, well, you have to do a lot of the cheering up on your own," Mukherjee said.

Now, however, that she is the new marketing director of the Adventure Aquarium in Camden, down times can't possibly last long, she said.

"Even if you are having a bad day, you walk on the floor and see the expressions of people - especially kids, but even parents - and you can't help but smile," she said. "You become refreshed. The people who come here are here to be happy."

Mukherjee moved to Cherry Hill last year, when her husband, Amit, became a professor of management at the Richard Stockton College of New Jersey. They have a 5-year-old son and a 21/2-year-old daughter. She had emigrated from India a decade before, after getting her master's in business at the University of Mumbai. She wanted to come to the United States for a few months, just to look at companies and how they applied marketing principles.

"That five months or so has now lasted 11 years," she said. She got another master's degree, in marketing, at the University of St. Thomas in Minnesota, and worked in the Twin Cities for the last 10 years. Each time, she took a job in a different industry, she said - from women's beauty-care items to a bank to Best Buy to a large regional utility company.

"Business is not like getting a degree in pure science. It is exciting to apply your ideas to the real world," Mukherjee said. She found that, when trying to market banking, or beauty items, or electronics, or even different kinds of billing for utility customers, it all came down to understanding customers.

"People now want more interaction with a company. They want to have some hands-on experience," Mukherjee said. They want to be able to pay their bills in the way they want, or play around with the controls on a TV, or, certainly, get close to a shark or a hippo at the aquarium.

The Adventure Aquarium determined in its initial market surveys that visitors would probably come back every 18 months or so, and now that the aquarium has been open under the Adventure name for about two years, it is time to seriously concentrate on getting people back.

"They've done a great job in building a brand, and it is now my job to move it along," she said. "The aquarium has gone from crawling to walking, and I have to get it to running."

She said the plan is to have five new exhibits and to market them in a slightly larger geographic area - a day's drive, more or less. She doesn't think it will be a hard thing to sell.
