Diane Ripley, Director of Education

Diane Ripley

Diane is a master of both art and science, literally. She has a BS in Biology and a MA in Teaching.  She “left a good job in the city” working at the Audubon Aquarium in New Orleans as both a volunteer and a public programs coordinator for her current position at INFINITY.  Diane served as a medical researcher specialist in the Microbiology Department at Tulane but for more than ten years, she has had a passion for the culinary arts, more specifically, pastries.  Needless to say, Diane is INFINITY’s most popular employee and has a lifetime membership to its pot luck dinners.

Joe Pettigrew, Staff Naturalist

Joe Pettigrew

Joe calls Kiln, MS, home although he was born and raised in Columbia, South Carolina.  A Clemson University graduate, he serves as INFINITY’s resident expert on anything that grows up from the ground, swims in water, or flies over the museum’s 199 acres in the Stennis Space Center buffer zone natural areas.  On the side, Joe is a forestry consultant and master naturalist.   Although INFINITY provides him a nice office phone, try reaching Joe on his cell instead, since he’s more likely to be out on the Possum Walk Trail, slogging through the banks of the Pearl River, canoeing its Bogue Homa tributary, or just helping turtles and ducklings cross the road and parking lot in front of the science center.
