After serving in the Army as a legal specialist, Ms. Greene worked at Ericsson, a telecommunications equipment and services company. She was trained in-house as a switch engineer, working on both TDMA and GSM cellular systems. Before leaving Ericsson, she was the product manager for third-party software and hardware.
She went back to school initially with the idea of becoming a pharmacist, but quickly fell in love with the science classes, especially microbiology and organic chemistry. After completing a summer National Science Foundation internship at the University of Wisconsin-Madison in Dr. Jo Handelsman's lab, looking for antibiotic resistance in the resident microbiota of the gypsy moth midgut, she decided to attend graduate school. She selected Baylor, because she was impressed with the work being performed at the Institute of Metabolic Disease at Baylor Research Institute, particularly in the molecular diagnostic department on heart disease. While working on her degree, she was offered a position with a biotechnology start-up company.
The biotechnology start-up brought her into the world of nanotechnology, where she learned about semiconductor manufacturing, nanotechnology, hybrid devices (electronic and biological), and device testing. While working for this company, she decided to once again enter the legal field and attend law school to become a patent attorney.
As a young child, Serena liked taking apart the household electronics and putting them back together, along with borrowing her older sister's chemistry sets and doing experiments. Her idea of a prank at the time differed from most. She enjoyed going to computer stores and programing short looping programs that usually consisted of color changing balls bouncing across the computer monitor, and then watching the confused staff.
"One should never stop learning, never stop exploring, never stop going on adventures. Be like the explorers of old. What they acquired for themselves will always surpass those who merely read about their exploits." –Ming-Dao Deng
