From Space Science to Science Fiction

From her earliest years, Adeena Mignogna (B.S. ’97, physics; B.S. ’97, astronomy) always saw space in her future. It started with “Star Wars.”

“I have memories of watching the first ‘Star Wars’ movie with R2-D2 and C-3PO when I was about 6 years old and I really connected with the robots, wanting to know how we make this a reality,” she recalled. “For a while, I thought I was going to grow up and have my own company that would make humanoid robots, but the twist was, we were going to live and work on the moon. I could even picture my corner office and the view of the moon out the window.”Adeena Mignogna Adeena Mignogna

For Mignogna, that boundless imagination and her childhood fascination with space and science launched two successful and very different careers—one in aerospace as a mission architect at Northrop Grumman, developing software and systems for satellites, and the other as a science fiction writer, spinning stories of robots, androids and galactic adventures in her many popular books. For Mignogna, space science and science fiction turned out to be a perfect combination. 

“I think of it as kind of like a circular thing—science fiction feeds our imagination, which possibly inspires us to do things in science. And science feeds the science fiction,” Mignogna explained. “Working in the space industry is something that I always wanted to do, and I always wanted to write as well, so I’m glad that I'm really doing it.”

Drawn to science

The daughter of an engineer, Mignogna was always drawn to science and technology.

“I am my father's daughter,” she said. “My dad brought home computers, and I learned to program in BASIC, so it was kind of always obvious that I was always going to do something STEM-ish.” 

Inspired by the real-life missions of NASA’s space shuttle and the Magellan deep space probe and popular space dramas like “Star Wars” and “Star Trek,” Mignogna’s interest in aerospace blossomed into a full-on career plan. As she prepared to start college at the University of Maryland in the early ’90s, she began steering toward two majors.

“At first, I thought maybe I'm going to major in astronomy because I loved space and space exploration,” Mignogna recalled. “But my high school physics teacher had degrees in physics, and he had done a lot of different things. He had worked at Grumman during the Apollo era, he had done astronomy work, and so I was like, ‘Okay, if I major in physics, I could do space stuff, I could do anything.’ So in the end, I majored in both.”

Surprisingly—at least to her—at UMD, Mignogna discovered she loved physics.

“What do I love about physics? It's very fundamental to how everything works,” she explained. “I used to tease my friends in college who majored in other sciences that at the end of the day, they were all just studying other branches of physics—like math is just the tool we use to describe physics and chemistry is an offshoot of atomic physics and thermodynamics. And even though I was making fun, I do probably think there's some truth to that, and that might be why I like physics so much.”

Hands-on with satellites

By her sophomore year, Mignogna got her first hands-on experience with aerospace technology.  

“I wound up getting a job in the Space Physics Group, and they built instrumentation for satellites,” Mignogna explained. “I happened to learn about this at the right time when they were looking for students for a new mission, and I worked on that mission from day one till we turned the instrument over to [NASA’s] Goddard Space Flight Center, which was very cool.”

Working in that very hands-on lab assembling and sometimes reassembling science instruments that would eventually fly in space, Mignogna realized she was on the right path. 

“I was touching spaceflight hardware. I was touching stuff that was going into space,” she recalled. “It was really exciting.”

For Mignogna, working side by side with space scientists at UMD and getting hands-on training in skills like CAD drafting gave her the tools she needed to land her first job at NASA’s Goddard Space Flight Center.

Mignogna eventually landed at Orbital Sciences Corporation, which later became part of Northrop Grumman. For the next 16 years—earning her master’s degree in computer science from the Georgia Institute of Technology along the way—she expanded her space software and systems expertise and became a leader in Northrop’s satellite engineering program.

“On the software side, I worked on our command and control software. We have a software suite that controls the satellites, and what I loved was that it gave me exposure and insight into so many different kinds of satellites,” Mignogna said. “With systems engineering, I’m able to go through what we call the full life cycle of the mission. When NASA says, ‘Hey, we need a satellite that's going to do X, Y, Z,’ as a systems engineer, we’re the ones who break that down, and I’m kind of the end-to-end broader picture person in that process. The group that I'm closely associated with today is responsible for Cygnus, which is one of the resupply capsules to the International Space Station.”

From science to science fiction

Over the years, as Mignogna’s career reached new heights so did her work as a science fiction writer, a creative effort that started when she was in high school.

“My dad was a fan of Isaac Asimov and Robert Heinlein, so I knew they were engineers and scientists who also wrote science fiction, and that was something I always wanted to do,” Mignogna said. “At first, I didn't think I could write novels, I thought I could only do short stories. But around 2009, I figured out I could, and I’ve been doing it ever since.”

With titles like “Crazy Foolish Robots” and “Robots, Robots Everywhere,” Mignogna’s Robot Galaxy Series combines science fiction with humor, philosophy and, of course, robots. Her latest book “Lunar Logic” is set on the moon, 100 years from now.

“There are humanoid robots, built and manufactured on the moon, and they live on the moon. And they don't know anything about humans or why they're there,” Mignogna explained. “And then little things happen and they start to question what's going on and why they're there and eventually they kind of figure it all out.”

In Mignogna’s sci-fi worlds, the only limit is her own imagination, which is exactly what makes her work as a writer so enjoyable. 

“In my science fiction work, it’s my way or the highway,” she said. “I can write whatever I want, and I can make it however I want, and there's some satisfaction in that.”

For Mignogna, writing science fiction also provides an opportunity to advance another mission—to get more people interested and excited about science. In regular appearances at sci-fi conferences and other gatherings, Mignogna shares her passion for STEM, hoping to inspire the next generation of scientists—and everyone else.

“All this technology we have today comes from generations upon generations of fundamental science, technology, engineering, mathematics,” she explained, “so if we're going to do more things, we need people to go into these fields. “

As someone who’s always seen the importance of science in her own life, it’s a message she’s committed to sharing.

“You don't have to understand everything about science, but you can appreciate it,” Mignogna noted. “My hope is maybe if I can just connect with a few people indirectly or directly, I can make a difference.”

Malcolm Maas Named 2025-26 Churchill Scholar

University of Maryland senior Malcolm Maas has been awarded a 2025-26 Churchill Scholarship, joining only 15 other science, engineering and mathematics students nationwide in winning the prestigious honor. 

“We could not be prouder of how Malcolm Maas represents the University of Maryland to the world,” said Amitabh Varshney, dean of UMD’s College of Computer, Mathematical, and Natural Sciences. “Malcolm is a phenomenal student researcher who is driven to understand complex world problems like climate change and provide innovative solutions to them.”Malcolm Maas.

Maas, who plans to graduate in three years with bachelor’s degrees in atmospheric and oceanic science (AOSC) and physics, will receive full funding to pursue a one-year master’s degree at the University of Cambridge’s Churchill College in the United Kingdom. The scholarship covers full tuition, a competitive stipend, travel costs and the chance to apply for a special research grant. 

Maas plans to pursue a Master of Philosophy degree in mathematics.

“I feel incredibly honored to have received this scholarship, and I’m very grateful to everyone who has supported me on my way here,” Maas said. “I’m excited for the opportunity to explore atmospheric dynamics further and to experience Cambridge next year.”

A total of 127 nominations this year came from 82 participating institutions. Ten UMD students have been nominated in the past seven years—and nine of them have been named Churchill Scholars.

“The University of Maryland’s remarkable success in racking up Churchill Scholarships testifies to the excellence of the research opportunities and mentorship our undergraduates receive,” said Francis DuVinage, director of UMD’s National Scholarships Office. “Malcolm Maas’ record of accomplishment as a third-year senior puts him in a class by himself.”

Since 2022, Maas has been working with AOSC Associate Professor Jonathan Poterjoy on fundamental challenges associated with environmental prediction and validation of atmospheric modeling systems. Specifically, he is quantifying the degree to which commonly used data assimilation methods shift models away from physically plausible solutions due to commonly adopted but incorrect assumptions. Maas presented their work in January 2025 at the American Meteorological Society Annual Meeting.

“Malcolm initiated our research collaboration on his own and I fully expect him to draft a first-author paper that we submit for publication this year,” Poterjoy said. “I feel that Malcolm can succeed in virtually any field, and I am pleased to see that he chose a research career in atmospheric science where his talents can have broad human impact.” 

Maas’ research interests and experiences extend beyond his work with Poterjoy and currently range from weather time scales to climate time scales. 

In summer 2024, Maas interned at the University of Chicago with Geophysical Sciences Professor Tiffany Shaw, where he assessed extreme heat and atmospheric circulation trends associated with Arctic sea ice loss in climate models and observational datasets. He presented this work at the American Geophysical Union’s Annual Meeting in 2024.

In summer 2023, Maas participated in the undergraduate summer intern program at the Lamont-Doherty Earth Observatory and worked on a project with Kostas Tsigaridis, a research scientist at Columbia University and the NASA Goddard Institute for Space Studies. Maas used a large dataset of Earth system model simulations to explore the effects of volcanoes on climate and atmospheric sulfur. He used machine learning to develop a tool that estimates where unidentified historical eruptions happened based on ice core data. Maas presented this work at the European Geosciences Union’s General Assembly in 2024 in Austria.

When Maas arrived at UMD in 2022, he joined a group of AOSC students installing and managing a micronet—a small-scale network of weather sensors—across the university’s campus. Five weather stations now provide minute-by-minute updates on the temperature, wind speed, pressure, dew point and rain rate on campus. Maas helped create the data collection system and user-friendly graphs to visualize the data, which are displayed on the UMD Weather website.

When the university and the Maryland Department of Emergency Management installed their first weather tower as part of the Maryland Mesonet in 2023, they asked Maas to quickly adapt his micronet visualization tools to work with the mesonet data. The 23 towers operational around the state—with more than 70 planned—help to advance localized weather prediction and ensure the safety of Maryland's residents and visitors.

For his Gemstone honors research project, Maas and 10 teammates have been working with UMD Mechanical Engineering Professor Johan Larsson to optimize the shape of marine propellers.

In high school, Maas helped build the first global tornado climatology database. He gathered and processed historical data for over 100,000 tornadoes that occurred around the world. The project’s website raked in 160,000 page views during its first year, and the work was published in the Bulletin of the American Meteorological Society in 2024.

Outside of class, Maas plays the pipe organ, represents the Ellicott Community on the Student Government Association, tutors with the Society of Physics Students and is a member of the Ballooning Club. He received a Barry M. Goldwater Scholarship, National Merit Scholarship, President’s Scholarship and the Department of Physics’ Angelo Bardasis Scholarship.

After his time at the University of Cambridge, Maas plans to pursue a Ph.D. in atmospheric science.

Connecting the Quantum Dots

Physics Ph.D. student Anantha Rao tests ways to build bigger and better quantum computers.

Anantha Rao grew up in Bengaluru, a city known as India’s tech hub due to its bustling startup culture and many international IT corporations. While many of Rao’s peers pursued engineering and related subjects, Rao’s love of science and knack for solving mathematical problems nudged him in a different direction.

“Everyone around me was an engineer or wanted to be one, and that is one thing I did not want to be,” Rao said. “I had this rebellious nature of going against the crowd, but I also wanted to solve fundamental problems in the basic sciences for the love of it—not for immediate applications.”

Rao discovered his calling after winning a high school physics competition. As a prize, he received a book written by Richard Feynman, a theoretical physicist who laid the groundwork for the field of quantum computing more than 40 years ago, and the field’s endless applications captivated Rao.

“Quantum computing has applications in studying how drug molecules bind to receptors or decrypting credit card transactions. You could study models of how the universe was created or see how the first molecule came into the picture,” Rao said. “Using ideas from quantum mechanics and computer science, you can also build better quantum computers, which is the problem that I’m looking at today.”

Now a Ph.D. student in the University of Maryland’s Department of Physics and Joint Center for Quantum Information and Computer Science (QuICS), Rao probes the fundamental physics that could power the next generation of quantum computers. He said he’s grateful for the chance to pursue that challenge in the “Capital of Quantum” at UMD.

“UMD is one of the top schools in the world for quantum information, especially theory,” Rao said. “Ten years ago, if someone told me that I'd be here now, I would feel like it is a dream.”

Tackling malaria with tech

Before moving to the United States, Rao was a full-time physics student and part-time entrepreneur in India. While Rao was enrolled in a combined bachelor’s and master’s program at the Indian Institute of Science Education and Research Pune, he cofounded a startup to develop diagnostic tools for diseases like malaria, a mosquito-borne infection that kills an estimated 608,000 people per year, according to the U.S. Centers for Disease Control and Prevention.

The software he developed, dubbed Deep Learning for Malaria Detection (DeleMa Detect), relied on artificial intelligence (AI) to search patients’ blood smear images for the signs and stages of malaria infection. This technology is packed into a small, portable device, reducing the need for lab tests that can be costly and inaccessible in many parts of the world.

Rao’s startup received a $50,000 grant and won top prize at the International Genetically Engineered Machine (iGEM) 2021 Startup Showcase. Rao has since moved on to other projects but said his early entrepreneurial experience taught him lessons about project leadership and collaboration that he applies to his research every day.

“I learned a lot about AI during my brief stint with entrepreneurship, and that’s something I've been working on lately—using AI to solve problems in physics,” Rao said. “My main motivation now is: What are the toughest problems out there and how can I solve them?Rao at TU Delft.Rao at TU Delft.

Since joining UMD’s physics Ph.D. program in 2023, he has been working to identify—and answer—those questions, one at a time.

The making of MAViS

One of Rao’s biggest ongoing projects is a collaboration between UMD, the National Institute of Standards and Technology and Delft University of Technology in the Netherlands. He has been leading the Modular Autonomous Virtualization System for Two-Dimensional Semiconductor Quantum Dot Arrays (MAViS) project, which aims to advance research that could lead to bigger and better quantum dot-based quantum computers.


Central to this concept are quantum dots, tiny semiconductor particles that serve as the building blocks of some quantum computers. These quantum computers operate at temperatures close to absolute zero, or −273.15 degrees Celsius—conditions that prompt the chips to engage in quantum mechanical behavior.

“The chips in your phone and chips in your laptop are made up of semiconductors, and similarly, we have quantum computers made out of semiconductors, except they operate at the coldest temperatures in the universe,” Rao explained. “The problem is you can't control them very well and you have a lot of unwanted interactions coming in.

To control each quantum dot, voltages must be applied to electrodes in their vicinity. Isolating this task can be tricky, though, because quantum dots are spaced just a few nanometers apart.

“What MAViS offers is a way to independently control each quantum dot in a very scalable and efficient way. This is a process called virtualization,” Rao explained. “Most importantly, it’s completely automatic. You press a button and MAViS solves a lot of equations faster than any human.”

By finding ways to offset unwanted interactions, which can introduce errors, researchers can make quantum computers run more efficiently and accurately. MAViS also uses “a little bit of AI” to enable corrections in real-time, Rao said.

Rao and his collaborators have seen encouraging results after testing MAViS on some of the world’s largest quantum dot devices in the Netherlands. MAViS successfully enabled researchers to operate and more efficiently control quantum dots, which in turn helps them control qubits—the fundamental building blocks of quantum computers.

Rao explained that one of the benefits of MAViS is that it works quickly and could free up time for researchers to focus on deeper tasks.

“We were able to do a task in about four hours that would have taken a month or two months of human effort,” Rao said. “Without MAViS, a lot of people with doctorate degrees would have needed to stare at computer screens and analyze complicated images to solve this problem. Now, researchers can automatically ‘virtualize’ their quantum dots and perform interesting experiments.”

Aside from his research with MAViS, Rao said his research on semiconductor qubits has also revealed some unusual physics, including elusive crystals made entirely of electrons.

“Another question in my research is: If you have these semiconductor quantum dots or quantum computers, what is some interesting physics that one could study in one dimension or two dimensions?” Rao said. “We've found evidence that exotic phases of matter—something called Wigner crystals—could be found in these devices.”

Giving back

As Rao dives deeper into quantum physics, he continually seeks ways to share his knowledge. MAViS and many of Rao’s past research projects involve open-source code so that the community at large can benefit.

“Since undergrad, I’ve wanted to give back to the community as I’ve learned things, and one way is through open-source projects and mentoring other students,” said Rao, who also worked as a teaching assistant and served on graduate student committees at UMD. “We hope to eventually make MAViS open source so that people anywhere in the world can build better, scalable quantum-dot quantum computers.”

After Rao graduates, he hopes to find a job that will enable him to keep tackling the big questions in quantum physics, whether that’s in academia or private industry.

“My pursuit is the best research and the best science that I can do today, and I believe that approach will give me the right opportunity in an academic lab or industry lab,” Rao said. “There are a lot of problems to solve in quantum, and I’m working toward solving them one at a time.”
