During Lehigh’s undergraduate Commencement on Sunday, May 18, Lumen Technologies’ Kate Johnson ’89 delivered the keynote address to graduates, families and guests, sharing her experiences as an undergraduate student at Lehigh and the subsequent lessons that have shaped her life and remarkable career.

A seasoned technology leader with a proven track record of driving business transformation success at several Fortune 100 companies including Microsoft and Oracle, Johnson’s professional career is marked by resilience and innovation—characteristics that also apply to the Class of 2025.

The 1,485 graduates who took the field at Goodman Stadium on Sunday were part of the first incoming class at Lehigh to return to a more traditional university experience following the COVID-19 pandemic, and they helped rebuild a thriving campus community. In the face of societal challenges like natural disasters, many applied their knowledge and skills to help address critical needs in society. They experienced the rise of artificial intelligence (AI) and many harnessed its ability to advance their learning and research.

During her address, Johnson recognized that the Class of 1989 and 2025 faced a world filled with similar challenges and uncertainties, noting that 36 years ago, there was a global health crisis, a violent geopolitical stage, a man-made environmental disaster and a new disruptive technology known as the World Wide Web.

“And here we are in 2025, once again facing great uncertainty,” Johnson said. “But this time, it seems to be coming at us with greater velocity and impact.”

She mentioned that as first-year students, the graduates were probably more focused on how the pandemic would shape their college experience. But then AI emerged “out of nowhere, posing as the single greatest study buddy ever” and reshaped their first job market.

As president and chief executive officer of Lumen Technologies since 2022, Johnson is leading Lumen through a fundamental transformation, from a legacy communications provider to the trusted network for AI. Johnson said their work has led to positive progress in the company’s financial health and stock price, and appears to be disrupting the industry.

She attributed the success to Lumen’s flexibility, noting that “companies who can adapt tend to prevail,” she said.

While graduates may be feeling anxious or concerned, Johnson assured they are not alone, and she reminded them that when history repeats, humans adapt, persevere and prevail.

“Class of 2025, you are those humans,” she said. “You need to help us figure this pattern out. We need you in the game—every single one of you.”

She said Lehigh gave the graduates the tools they need to be successful and taught them how to “play to win.” According to Johnson, that means “building the life you want no matter what the world around you looks like.”

She encouraged graduates to focus on discovering what is right for them and where they can have a meaningful impact. She urged the Class of 2025 to adopt a “learn-it-all mindset” and commit to “showing up with more questions than answers, and using that information to grow and adapt.”

Lastly, Johnson stressed the importance of surrounding yourself with a great team at home, work and elsewhere, since “human connection has the power to make us stronger, especially in uncertain times.”

Turning Challenges into Positive Change

For some of the graduates, the changes and challenges that happened around them during their undergraduate years—from the impact of the pandemic and natural disasters to the rise of new technology like AI—sparked an interest in related studies and research.

Following the pandemic, Monelli Esfandiary ’25, a population health major in Lehigh’s College of Health, was motivated to use her passion for biostatistics to help predict infectious disease outbreaks before they happen.

She worked alongside Tom McAndrew, assistant professor in the Department of Biostatistics and Health Data Science, to develop weekly flu forecasts and interpret the impact of COVID-19 on flu case numbers and trends for the Pennsylvania Department of Health using a metapopulation model. Most recently, her research with McAndrew was based on predicting the Northern Hemisphere’s flu season before it happens.

“A huge lesson from the pandemic was that we have to find out how infectious diseases spread before they cause an outbreak because that is how we could save populations,” Esfandiary said. “Forecasting and flu predictions are able to do that.”

At Lehigh, Esfandiary said she found a love for health and technology that she will carry with her as she pursues a masters of public health in biostatistics and epidemiology at the Keck School of Medicine at the University of Southern California.

“I love the challenge of it, and seeing the positive change that our research had makes me want to keep going,” Esfandiary said.

Kathryn Neumann ’25, a civil engineering and environmental studies major in the IDEAS (Integrated Degree in Engineering, Arts and Sciences) program, recalled when Hurricane Ida brought heavy rain to South Mountain during her first semester on campus in 2021.

Some parts of the Lehigh Valley region received up to eight inches of rain, which caused severe flooding and damage.

That experience and the increasing intensity of rainstorms in the Lehigh Valley, paired with Neumann’s hydrology-based civil engineering classes, piqued her interest in hurricane-related research.

“I have a big interest in modeling how storms are intensifying from climate change,” Neumann said.

As a Clare Booth Luce Scholar for the P.C. Rossin College of Engineering and Applied Science, Neumann has been researching regional resilience modeling in Lehigh’s Center for Catastrophe Modeling and Resilience under Paolo Bocchini, director of the center and professor of civil and environmental engineering.

Her research focuses on the resilience of communities in the face of worsening weather events. She has utilized her coding skills and civil engineering knowledge to complete two studies: A combined hazard and vulnerability analysis to assess the susceptibility of power transmission lines in Florida under hurricane wind conditions, and the importance of detailed powerline modeling in assessing the functionality of a power network under hurricane wind conditions.

Additionally, Neumann worked at the Lehigh Valley Planning Commission during her senior year, where she aided in updating stormwater ordinances to help reduce flooding problem areas within the Lehigh Valley.

She will be presenting her Center for Catastrophe Modeling and Resilience research at the International Conference on Structural Safety and Reliability (ICOSSAR) in June in California, and she is interested in pursuing a master’s degree from Lehigh’s new catastrophe modeling and resilience program in the future.

Leveraging New Technology

In 2022, the launch of ChatGPT and other generative AI tools spurred widespread curiosity and interest in AI. From writing code to creating artwork to drafting emails, the technology’s ability to perform a variety of tasks autonomously and efficiently changed how the Class of 2025 works and learns.

Renzo Medina ’25, an industrial systems engineering major and business minor, was excited by the potential of AI when he first learned about it. He began exploring its uses and value as a sophomore at Lehigh, first interacting with a chatbot to answer questions about his classes and utilizing AI tools to assist in project planning for his engineering classes.

“It was interesting to me because there was machine learning before AI, but AI was coming up with new solutions, and it was more personalized and customizable,” Medina said.

Driven by his interests in AI and community building, Medina co-founded HawkHousing, an OpenAI-powered app designed to help Lehigh students simplify the process of finding off-campus housing and ideal roommates. Medina, a 2024 Marcon Institute Fellow, began developing the app as part of his fellowship.

The app works by asking users a list of questions to gauge preferences like social activity, hobbies, cleanliness and more before matching them with compatible potential roommates and off-campus properties. The app also makes it easier for students to list and find sublease opportunities.

HawkHousing aims to foster vibrant communities beyond campus and empower underrepresented communities in the Lehigh Valley, which Medina said sets it apart from other housing websites and classified advertisement platforms.

“We wanted the app to have networking and social pieces,” Medina said. “Students can use this to lead other communities around them.”

HawkHousing won the People’s Choice Award at Lehigh’s Baker Institute for Entrepreneurship, Creativity and Innovation EUREKA! Pitch Night in March, and the app officially launched in April, receiving positive feedback from students in its first month, Medina said.

An incoming middle school science teacher at Success Academy Charter School in New York City, Medina said he plans to continue working on and growing HawkHousing after graduating from Lehigh.

Medina said he hopes HawkHousing serves as an inspiration for others to explore AI and utilize it to move their ideas forward and spark innovation.

“I would definitely encourage people to use AI and become entrepreneurs and innovators,” Medina said. “Embrace that passion, and just do it. Believe in yourself and then the partners around you are going to believe in you, too.”

‘We Watched and Worked Together’

President Joseph J. Helble ’82 opened the undergraduate Commencement ceremony and introduced Provost and Senior Vice President for Academic Affairs Nathan Urban, who greeted the graduates and guests.

Urban introduced Kaitlyn Powel ’25, a computer science and engineering major in the IDEAS (Integrated Degree in Engineering, Arts and Sciences) program. Powel was a member of the undergraduate student staff of the Pride Center at Lehigh and served on the executive boards of multiple organizations on campus, including Students Promoting Equality, Awareness and Knowledge (SPEAK), IDEAS Student Association, the club swim team and Alpha Gamma Delta, her sorority.

She received two awards at Lehigh’s 39th Student Life Leadership Awards, including the Contribution to Student Life Award and the Outstanding Educational Programming Award.

Powel reflected on the graduates’ time at Lehigh, noting that many chose to attend the university before ever having the chance to visit campus due to the pandemic.

“Whether flights were impossible to catch or tours just weren’t happening, we took a leap into the unknown, and somehow, we landed right where we needed to be,” Powel said.

The class saw many university milestones throughout their years as undergraduate students, she said. These milestones included the 50th anniversary of women being admitted to Lehigh, the opening of the Health, Science and Technology Building (HST) and the Business and Innovation Building, and the reopening of the newly-renovated Clayton University Center at Packer Hall.

“We watched and worked together as Lehigh rebuilt itself after the pandemic,” she said.

In addition to working together, Powell said her fellow graduates challenged each other every day to become the best versions of themselves and bridge gaps between different areas of student life on campus.

“I have seen us plant seeds of belonging that will hold future generations accountable to strive for inclusive excellence,” Powel said.

Powel reminded the graduates that their growth as Lehigh students will be of benefit in their next chapters.

“It is Lehigh’s academic rigor paired with years of mental and personal growth that equips us not just with knowledge, but with empathy, resilience and awareness to carry us wherever we find ourselves next,” Powel said.

‘Remember the Impact You Have Had’

Helble returned to the podium to address graduates and recalled challenges the Class of 2025 has witnessed, “from navigating the pandemic to global events that have deeply affected our communities to growing public scrutiny of higher education.”

“And yet even in the most challenging moments, I would find that I could simply step outside, run into some of you, and it would remind me of why higher education, why our work here at Lehigh, why your work, matters to us all so much,” Helble said. “Your grounded optimism—your realistic, pragmatic, determined optimism—is uplifting for each and every one of us. And Class of 2025, from the bottom of my heart, I thank you for that.”

He then stressed the importance of listening as a leader.

“I believe the single most important thing a leader can do, the single most important thing a skilled communicator can do, is listen—truly listen,” Helble said.

He told the graduates that giving full and undivided attention can be difficult due to digital connectivity and the pace of our lives.

“It isn’t easy, but I will tell you that over my long career, the individuals who have impressed me the most, and the colleagues I have respected the most, are those who truly listen,” he said.

Helble quoted President Calvin Coolidge, who once said, “No man ever listened himself out of a job.”

He followed the quote with a request to the graduates to do the hard work and be attentive listeners.

“Class of 2025, when you go out in the world, I ask you, remember the impact you have had around those of us who have listened to you,” Helble said. “Please give that gift to one another and carry that forward. Do the hard work. Truly and deeply listen. It will make such a difference in your lives and the lives of those around you.”
