Formal Job Classification: Optical engineer
Organization: Code 551, Optics Branch, Instrument Systems and Technology Division, Engineering Directorate
What do you do and what is most interesting about your role here at Goddard? How do you help support Goddard’s mission?
I build space telescopes. I am currently working on building one of the components for the Wide Field Instrument for the Roman Space Telescope. The component is called “Grism.” A grism is a combination of a grating and a prism.
What is unique about your childhood?
I went to high school in Tecamachalco in Puebla, Mexico, which is inland and south of Mexico City. My father raised pigs, chickens, rabbits, and cows. I am the oldest of four girls and two still live on the farm.
Why did you become a physicist?
I was always curious and had a lot of questions and thought that physics helped me answer some of these questions. I was good at math and loved it. When I told my dad I wanted to study physics, he said that I would be able to answer any question in the universe. He thought it was very cool.
What is your educational background? How an internship help you come to Goddard?
I went to the Universidad de las Americas Puebla college in Puebla and got an undergraduate degree in physics. I was very active in extracurricular activities and helped organize a physics conference. We invited Dr. Johnathan Gardner, a Goddard astronomer, who came to speak at the conference. Afterwards I spoke with him and he asked me if I was interested in doing an internship at NASA. I said I had not considered it and would be interested in applying. I applied that same spring of 2008 and got a summer internship in the Optics Branch, where I am still working today.
My branch head at Goddard was a University of Arizona alumnus. He suggested that I apply to the University of Arizona for their excellent optics program. I did, and the university gave me a full fellowship for a master’s and a Ph.D. in optical sciences.
In 2014, I began working full time at Goddard while completing my Ph.D. I graduated in May 2019.
What makes Goddard special?
Goddard has a university campus feel. It’s a place where you can work and also just hang out and socialize. Goddard has many clubs, a gym, cafeterias, and a health clinic.
People are really nice here. They are often excited and happy about working at Goddard. Most people are willing to put in the extra effort if needed. It makes work stimulating and exciting. Management really cares and the employees feel that too.
What are some of the major projects you have worked on?
Early on, I did a little bit of work on Hubble and later on, NASA’s James Webb Space Telescope. Since 2014, I have exclusively been working on Roman. We are building the grism, a slitless spectrograph, which will measure galaxy redshifts to study dark energy.
Presently we are building different grism prototypes. We work with outside vendors to build these prototypes. When we make a prototype, we test it for months. After, we use the results to build an improved prototype. We just finished making the third prototype. We are going to build a flight instrument of which the grism is a component.
What is it like to work in the clean room?
It’s exciting – it likely means I am working on flight hardware. However, because clean rooms must be kept at about 68 degrees Fahrenheit, it can feel chilly in there!
Who are your mentors? What are the most important lessons they have taught you?
Ray Ohl, the head of the Optics Branch, is a mentor to me. He is always encouraging me to get outside my comfort zone. He presents other opportunities to me so that I can grow and listens to my feedback.
Cathy Marx, one of the Roman optical leads, is also a mentor to me. She created a support network for me and is a sounding board for troubleshooting any kind of work-related issues.
What is your role a member of the Hispanic Advisory Committee (HACE)?
I joined HACE in 2010 while I was an intern. It’s a great opportunity to network with other Hispanics and gives us a platform to celebrate specific events like Hispanic Heritage Month. I really enjoy participating in HACE’s events.
What outreach do you do? Why is doing outreach so important to you?
I do educational outreach to teach people about optics. I mainly collaborate with elementary and middle schools.
I think we need more future engineers and scientists. I want to help recruit them. I specifically focus on recruiting minorities and Hispanics. I can make a special connection with women and Hispanics.
Who is your science hero?
It would probably be Marie Curie. She’s the first woman to win a Nobel Prize, and she is the only woman to win two Nobel Prizes and she had to overcome a lot of challenges to achieve that.
What is your “six-word memoir”? A six-word memoir describes something in just six words.
Disciplined. Organized. Diligent. Passionate. Curious. Family-oriented.
Is there something surprising about your hobbies outside of work that people do not generally know?
I am a certified Jazzercise instructor – I normally teach two to three times a week. I can even teach virtually if need be. It is an hour-long exercise class combining strength training and cardio through choreographed dancing. We also use weights and mats.
I also enjoy going for walks with my husband, James Corsetti, who is also an engineer in the Optics Branch.

A summer barbecue transformed into a nightmare when lightning split the sky above Somerset, England. Peter Williamson dashed across his rain-soaked lawn to rescue his terrified dog, unaware that his next step would carry him beyond the boundaries of our world.
His family watched in horror as a blinding flash illuminated his silhouette against the stormy sky. When their vision cleared, Peter had evaporated into thin air.
The police launched a search, but found no footprints, no scorch marks, and no explanation for how a man could disappear from a walled garden. Sixteen witnesses swore they watched him vanish in plain sight.
Three days passed before Peter materialized in his backyard, wearing unfamiliar clothes and carrying items that defied explanation. His memories painted a picture of a hospital that both existed and didn't exist, where reality shimmered like heat waves rising from summer pavement.
The investigation into his disappearance uncovered something extraordinary: evidence suggesting Peter had slipped through a crack between parallel universes.
A "crack between parallel universes" is a metaphorical concept in physics, often used to describe a hypothetical point or region where two separate parallel universes could potentially interact or intersect with each other, allowing for potential travel or communication between them.
If such a "crack" existed, it would likely demand extraordinarily extreme conditions, exactly the kind Peter Williamson encountered during his disappearance.
His impossible story forces us to question everything we think we know about the nature of reality.

ESA/Hubble & NASA, C. Murray This NASA/ESA Hubble Space Telescope image features a dusty yet sparkling scene from one of the Milky Way’s satellite galaxies, the Large Magellanic Cloud. The Large Magellanic Cloud is a dwarf galaxy situated about 160,000 light-years away in the constellations Dorado and Mensa.
Despite being only 10–20% as massive as the Milky Way galaxy, the Large Magellanic Cloud contains some of the most impressive nearby star-forming regions. The scene pictured here is on the outskirts of the Tarantula Nebula, the largest and most productive star-forming region in the local universe. At its center, the Tarantula Nebula hosts the most massive stars known, weighing roughly 200 times the mass of the Sun.
The section of the nebula shown here features serene blue gas, brownish-orange dust patches, and a sprinkling of multicolored stars. The stars within and behind the dust clouds appear redder than those that are unobscured by dust. Dust absorbs and scatters blue light more than red light, allowing more of the red light to reach our telescopes, which makes the stars appear redder than they are. This image incorporates ultraviolet and infrared light as well as visible light. Using Hubble observations of dusty nebulae in the Large Magellanic Cloud and other galaxies, researchers can study these distant dust grains, helping them better understand the role that cosmic dust plays in the formation of new stars and planets.

A Satellite for Optimal Control and Imaging (SOC-i) CubeSat awaits integration at Firefly’s Payload Processing Facility at Vandenberg Space Force Base, California on Thursday, June 6, 2024. SOC-i, along with several other CubeSats, will launch to space on an Alpha rocket during NASA’s Educational Launch of Nanosatellites (ELaNa) 43 mission as part of the agency’s CubeSat Launch Initiative and Firefly’s Venture-Class Launch Services Demonstration 2 contract.NASA NASA is collaborating with the U.S. Air Force and U.S. Space Force to offer a set of hands-on learning engagements that will help higher education institutions, faculty, and students learn more about what it takes to build small satellites and enhance the potential to be selected for flight opportunities.
Teams selected for the University Nanosatellite Program Mission Concept 2025 Summer Series will receive systems engineering training that prepares them for the industrial workforce while developing small satellite expertise at U.S. universities. The program, which runs from May through August 2025, also enhances students’ potential to be selected for flights to space as part of NASA’s CSLI (CubeSat Launch Initiative) and the U.S. Air Force University Nanosatellite Program.
“Part of NASA’s mission is to inspire the next generation,” said Liam Cheney, CSLI mission manager at the agency’s Kennedy Space Center in Florida. “The CubeSat Launch Initiative is providing opportunities for students and educators to experiment with technology and send their missions to space.”
The program allows faculty and students to form teams for the summer program without using university resources, and includes travel funding for kickoff, final event, and any in-person reviews, among other benefits.
All U.S colleges and universities are eligible, and teams at minority-serving institutions and Historically Black Colleges and Universities are strongly encouraged to apply for the Mission Concepts 2025 Summer Series in accordance with the criteria in the request for proposal. The solicitation opened on Jan. 6, with a deadline to apply by Monday, Feb. 3.
The agency’s collaboration with the U.S. Air Force and U.S. Space Force helps broaden access to space and strengthen the capabilities and knowledge of higher education institutions, faculty, and students.
NASA’s CubeSat Launch Initiative provides opportunities for CubeSats built by U.S. educational institutions, and non-profit organizations, including informal educational institutions such as museums and science centers to fly on upcoming launches. Through innovative technology partnerships NASA provides these CubeSat developers a low-cost pathway to conduct scientific investigations and technology demonstrations in space, thus enabling students, teachers, and faculty to obtain hands-on flight hardware design, development, and build experience.

NASA Open Science Reveals Sounds of Space
A composite image of the Crab Nebula features X-rays from Chandra (blue and white), optical data from Hubble (purple), and infrared data from Spitzer (pink). This image is one of several that can be experienced as a sonification through Chandra’s Universe of Sound project. X-ray: NASA/CXC/SAO; Optical: NASA/STScI; Infrared: NASA-JPL-Caltech NASA has a long history of translating astronomy data into beautiful images that are beloved by the public. Through its Chandra X-ray Observatory and Universe of Learning programs, NASA brings that principle into the world of audio in a project known as “A Universe of Sound.” The team has converted openly available data from Chandra, supplemented by open data from other observatories, into dozens of “sonifications,” with more on the way.
Following the open science principle of accessibility, “A Universe of Sound” helps members of the public who are blind or low vision experience NASA data in a new sensory way. Sighted users also enjoy listening to the sonifications.
“Open science is this way to not just have data archives that are accessible and incredibly rich, but also to enhance the data outputs themselves,” said Dr. Kimberly Arcand, the visualization scientist and emerging technology lead at Chandra and member of NASA’s Universe of Learning who heads up the sonification team. “I want everybody to have the same type of access to this data that I do as a scientist. Sonification is just one of those steps.”
Data sonification of the Milky Way galactic center, made using data from NASA’s Chandra X-ray Observatory, Hubble Space Telescope, and Spitzer Space Telescope. While the Chandra telescope provides data in X-ray wavelengths for most of the sonifications, the team also took open data from other observatories to create a fuller picture of the universe. Types of data used to create some of the sonifications include visual and ultraviolet light from the Hubble Space Telescope, infrared and visual light from the James Webb Space Telescope, and infrared light from the now-retired Spitzer Space Telescope.
The sonification team, which includes astrophysicist Matt Russo, musician Andrew Santaguida (both of the SYSTEM Sounds project), consultant Christine Malec, and Dr. Arcand, assigned each wavelength of observation to a different musical instrument or synthesized sound to create a symphony of data. Making the separate layers publicly available was important to the team to help listeners understand the data better.
“It’s not just about accessibility. It’s also about reproducibility,” Arcand said. “We’re being very specific with providing all of the layers of sound, and then describing what those layers are doing to make it more transparent and obvious which steps were taken and what process of translation has occurred.”
For example, in a sonification of the supernova remnant Cassiopeia A, modified piano sounds represent X-ray data from Chandra, strings and brass represent infrared data from Webb and Spitzer, and small cymbals represent stars located via visual light data from Hubble.
Data sonification of the Cassiopeia A supernova remnant, made using data from NASA’s Chandra X-ray Observatory, James Webb Space Telescope, and Hubble Space Telescope. The team brought together people of various backgrounds to make the project a success – scientists to obtain and interpret the data, audio engineers to mix the sonifications, and members of the blind and low vision community to direct the product into something that brought a greater understanding of the data.
“Another benefit to open science is it tends to open those pathways of collaboration,” Arcand said. “We invite lots of different community members into the process to make sure we’re creating something that adds value, that adds to the greater good, and that makes the investment in the data worthwhile.”
A documentary about the sonifications called “Listen to the Universe” is hosted on NASA+. Visitors can listen to all the team’s sonifications, including the separate layers from each wavelength of observation, on the Universe of Sound website.
