NIVIA COLON-DIAZ
Sensors
What she does
As a research electronics engineer, Nivia Colon-Diaz is currently developing “methodologies to assess mutual coupling effects on the next generation of radio frequency (RF) sensors.”
She asserts that, “these sensors are digital with a wide band frequency range so they are capable of performing different functions simultaneously.”
Since these sensors have different modes, they can perform as a radar system or as a communication system or both simultaneously. However, it is possible that the interaction between them could cause the sensor’s performance to decline, she explains.
Colon-Diaz’s job is to analyze this negative interference and identify ways to control it. Her process is to develop methodologies, perform simulations and then conduct tests. She uses AFRLs anechoic (echo-free) chamber to obtain precise measurements since the room completely absorbs the reflections of sound and electromagnetic waves.
Why she enjoys her work
Colon-Diaz says she truly enjoys the entire process of sensor development. She explains that her goal in isolating problem areas is to determine ways to improve sensor technology and enhance the overall performance.
She begins any project by researching the various issues that cause interference. After identifying a particular area, she creates a test to measure the level of interference. In her latest project, she is in the process of validating the results and comparing her simulations with actual sound data.
Why she chose engineering
Colon-Diaz, who is pursuing a Ph.D. in electrical engineering, says she dreamed of being an inventor since childhood. She recalls being fascinated with telephone signals and antennas. This natural curiosity led her to study engineering.
The best part of her job
She explains that, “the greatest satisfaction is being able to directly support the Air Force mission and advance technology for the warfighter.”
Her advice to young people interested in STEM
She recommends that students “identify a mentor that [they] greatly appreciate, and learn as much as [they] can from that person.”>
Colon-Diaz supports programs that pair students with AFRL scientists. She says this experience is beneficial since it allows students to explore various areas of research first-hand.
Her thoughts on why recent graduates should consider AFRL
“AFRL offers many different opportunities to grow professionally and personally,” she asserts. “It also enables people to directly impact the warfighter’s mission and serve our great country.”
What she hopes to accomplish through her career
“Being a Hispanic woman, I think my greatest hope is to become a role model for the next generation of female students,” she says. Colon-Diaz asserts she wants to inspire minorities and encourage them to pursue careers in STEM.
