Mason's Women in Tech Spotlight: Kelly Glebus Anonymous (not verified) Mon, 03/15/2021 - 15:24

Senior computer science (CS) major, Honors College student, and aspiring software engineer Kelly Glebus was surprised by how few women were among her peers. Once Glebus reached higher-level CS classes, she says it wasn’t uncommon for her to be one of four or five women in a class of 30 to 40 students.

When she was a junior in high school, she enrolled in a pre-AP computer programming class as an elective. While the class wasn’t her first choice, she quickly developed an interest in programming and learned that she was adept at problem-solving.

“On the first day and my teacher got out these huge pieces of butcher paper and had us create these “thread” conversations on them,” says Glebus. “We were answering questions like ‘What jobs are we going to lose to computer automation?’, ‘What are ways that computers make our lives easier,’ and things like that. I thought that it was a very interesting way to begin a class, so I stayed in it.”

Her interest in programming did not go unnoticed by her teacher. Glebus says “he encouraged me to continue (and gave me all the extra work I asked for), and I decided that I was going to college for computer science. He really changed my life, and I’m very grateful for him. We’re still in touch today!”

Since then, Glebus has developed into a young professional. She interned at Forward Integration Technologies as a junior software developer, where she worked with Angular and Python to do full-stack web app development. She is currently a cybersecurity intern at Colvin Run Networks doing user interface design amongst other projects.

Some more notable achievements Glebus is proud of was being “a part of the National Science Foundation Research Experience for Undergraduates held at George Mason University in 2018, where I did some research with wearable technologies. I’m also currently a class facilitator for CS395: Student-Initiated Class Introduction into the Internet of Things.”

Given her passion for the field, Glebus encourages other women to try computing. She praised George Mason University's Department of Computer Science for being inclusive towards all students.

“I think a lot of super qualified women feel intimidated either by the subject or even by the male-dominated environment,” says Glebus. “Like I said before, computer science is hard, there are classes that you couldn’t pay me to retake, but that doesn’t mean it’s impossible. I wish more women would take the leap and try it; I think they’d find that they’re really good at it. Like I did.”

On March 3, Mason announced a new initiative, Break Through Tech, that aims to propel more students who identify as women and non-binary into tech education—and ultimately tech careers—through curriculum innovation, career access, and community building. The goal of the grant is to increase the number of these students graduating with a tech degree at Mason by 12.5 percent by 2026.

Computer science researcher investigating ways to reduce bias in software Nanci Hellmich Sun, 09/20/2020 - 15:20

“We need more diverse perspectives in computer science just like we need them in the boardroom. If we have more diversity in computer science, we will see more diversity and equity in our solutions.”

— Brittany Johnson, an assistant professor of computer science

Brittany Johnson, an assistant professor of computer science, is researching ways to eliminate or reduce bias in software.

A Mason Engineering professor is on a mission to improve software development so that computer programs are fair to everyone.

“We develop technology using real-world data, but that data can have biases that affect the output of the software,” says Brittany Johnson, an assistant professor in the Department of Computer Science. It happens in software developed for healthcare, banking, and retail, she says.

“For example, in healthcare, we use algorithms that help decide on treatment and prioritize patients. Unfortunately, these have been shown to be biased against certain groups, such as African Americans,” she says.

Johnson is determined to change that. Her research evaluates tools and practices that support analyzing software and its components for bias. “It’s important we understand what’s being done in practice and provide solutions for building and using fair, equitable software,” she says.

David Rosenblum, chair of the Department of Computer Science, says, “Businesses, healthcare providers, law enforcement, and government agencies now rely heavily on algorithmic tools to make critical decisions affecting people’s lives.

“Unfortunately, because of the way these tools are programmed, they often embody significant biases that result in unsound and even detrimental decisions. Brittany’s research promises to understand and attack the sources of bias in these tools to ensure fair and sound decision-making,” he says.

Before joining Mason, Johnson was a postdoctoral research fellow at the University of Massachusetts Amherst, where she developed a new testing technique, called Causal Testing, that supports developers in understanding the cause of unexpected behavior in their software.

In addition to her passion for research, Johnson enjoys mentoring students both inside and outside the classroom. Before the pandemic, she taught and mentored middle and high school students at workshops and camps.

She doesn’t want young people to be intimidated by computer science. “Computer science is so much more than writing code and memorizing algorithms,” she says.

“I want to help attract a more diverse perspective to computer science,” Johnson says. “We need more diverse perspectives in computer science just like we need them in the boardroom. If we have more diversity in computer science, we will see more diversity and equity in our solutions.”

The fix is in: Computer science researcher creating system to help resolve bugs in software

"We are developing a modern, intelligent bug reporting system, using artificial intelligence and program analysis behind the scenes. It’s a different technique for analyzing potential problems in computer programs."

— Kevin Moran, assistant professor of computer science

Kevin Moran, an assistant professor in the Department of Computer Science, is developing a new system that could help fix technical problems in computer software more quickly and efficiently.

Tracking down bugs in software can be frustrating and time-consuming for engineers, but a Mason Engineering researcher is creating a new system that could help fix technical problems more quickly and efficiently.

Kevin Moran, an assistant professor in the Department of Computer Science, is researching a type of autofill system that would allow users to type in a few words about the issue they’re experiencing and then the system would attempt to pinpoint the problem in the code.

“Current software bug reporting systems have not kept up with the complexity of modern software, but our vision is that bugs will be uncovered and fixed using our proposed interactive BUg ReporTing (BURT) system,” he says.

Moran along with computer science professor Denys Poshyvanyk and assistant professor Oscar Chaparro at William & Mary and computer science professor Andrian Marcus at the University of Texas at Dallas received a $1.2 million award from the National Science Foundation for their research project, Bug Report Management 2.0,

Bug reporting systems serve an essential role in documenting problems during software development, Moran says.

Current systems largely capture information using natural language or graphical information, such as screenshots. The restrictive nature of these interfaces makes it hard to get to the bottom of the problem, Moran says.

“We are developing a modern, intelligent bug reporting system, using artificial intelligence and program analysis behind the scenes. It’s a different technique for analyzing potential problems in computer programs,” he says.

The result: “With our system, the person reporting a problem would type in some text about the issue they are trying to solve with a piece of software, and the system, using machine learning, would predict what that person is describing and specific areas of the code that could be analyzed to resolve the issue,” Moran says.

David Rosenblum, chair of the Department of Computer Science, says, “developing and debugging software remains notoriously difficult, and with so much critical human activity being centered around complex software, it’s essential to give developers powerful tools to grapple with the detection, isolation, and elimination of bugs.

“The research of Kevin and his colleagues takes a very different approach to this problem by exploiting the power of machine learning in conjunction with more established forms of program analysis. Their approach promises to significantly decrease the turnaround time for eliminating bugs in software,” he says.

Moran also received a $500,000 award from the National Science Foundation for his research project, Towards a Holistic Causal Model for Continuous Software Traceability, which is being conducted with researcher Denys Poshyvanyk at William & Mary.

This project is trying to automate the process of linking different pieces of code to descriptions of their functionality, Moran says. This process, called traceability, is a critical step in verifying software where safety or security is critical.

Moran is working on his research remotely during the coronavirus pandemic. “It has been a bit of an adjustment with virtual meetings and not discussing ideas on a whiteboard,” he says. “But we have gotten used to this new normal of vetting research ideas on Zoom.”
