Longtime Staff Member Lorraine DeSalvo Retires

After 41 years tending to the people and places of the Department of Physics, Director of Administrative Services Lorraine DeSalvo retired in December. In tribute, colleagues established the Lorraine DeSalvo Chair's Endowed Award for Outstanding Service to provide annual recognition to physics employees who demonstrate exemplary commitment to their work. 

DeSalvo graduated from the University of Maryland in 1972 and immediately accepted a job in the Department of Chemistry. 

“I have had the pleasure of knowing so many truly wonderful staff members on this campus during my years here,” she said. “Having this fund to recognize physics department colleagues is the finest farewell I could have asked for.” 

DeSalvo’s duties covered both facilities and human relations, meaning that she knew every inch of space and every employee. Her vast institutional memory and cross-campus contacts allowed her to untangle innumerable bureaucratic knots.  As Department Chair Steve Rolston noted, the most commonly uttered phrase in the department in recent decades may well have been, “Just ask Lorraine.” 

Modern, energy-intensive physics experiments long strained the aging infrastructure of the John S. Toll Physics Building and required constant vigilance and frequent, extensive renovations. When funding was approved for the new Physical Sciences Complex, DeSalvo’s workload expanded considerably. She worked with architects, builders, and capital improvement staff to plan the move, order furniture, and ensure that labs were built to the exacting specifications of dozens of extremely particular scientists. 

She fostered camaraderie with vibrant holiday parties and memorable fiestas, extending invitations to helpful colleagues across a swath of campus sectors. To the department’s many international students, scholars and visitors, she extended her welcome, wisdom and warmth. She owned a variety of small stuffed flamingos, which she dispatched to travelers with a request for a scenic photo. A slideshow of UMD physics folks hoisting pink birds across the globe ran continually in her office. 

She also displayed a keen regard for the department’s achievements. 

After the death of physicist Joe Weber in 2000, his lab fell into disuse. DeSalvo kept protective watch over the “Weber bars,” colossal aluminum cylinders built to record gravitational waves. Years later, in 2015, the LIGO experiment detected gravitational waves, generating worldwide acclaim and renewing interest in Weber’s quest. Last March, the Weber Garden was dedicated outside of the Physical Sciences Complex.  

“Without Lorraine’s protective instincts and her foresight that the Weber bars would prove significant, these excellent monuments to UMD innovation would have been lost forever to campus and the world,” Rolston said.

As a retiree, DeSalvo says she looks forward to finding the best crab cake restaurants around—and to keeping in touch with the department. 

She was serenaded at her retirement party by the following: 

Her global flamingos and holiday parties
And summer fiestas gave Physics some verve
And year in and year out, there surely could be no doubt
How heartfelt is her motto of “I live to serve.”

Summer Camps Introduce High School Girls to Physics

Since its inception in 1988, over 1,500 students have participated in the University of Maryland’s Summer Girls physics program for rising 9th through 12th graders. Last summer alone, more than 50 young students came to campus for one or two weeks to explore concepts from classical and modern physics, conduct hands-on laboratory experiments, and learn about careers in physics. The students also met and spoke with physics professors and graduate students, listened to interesting lectures, and toured research laboratory tours. 

The program is mostly funded by a grant from the National Science Foundation through the Physics Frontier Center at the Joint Quantum Institute. Students paid only $25 to participate last year. Participants of the program, which is directed by Donna Hammer, have come not only from Maryland, Virginia and Washington, D.C., but also from Pennsylvania, New Jersey and all over the world. Graduates have gone on to become engineers, doctors, computer scientists and, of course, physicists. 

 

    

Recent Alumnus Zachary Eldredge Studies Solar Energy as ORISE Fellow

As a student, Zachary Eldredge (Ph.D. ’19, physics) examined the use of quantum mechanics to improve measurements.

“If you nEldredge 2020Zach Eldredge.

Our methods are more accurate because we only measure once, not twice.”

After graduating last May, Eldredge took this expertise and his strong physics foundation to the Department of Energy’s Solar Technologies Office, which aims to make solar energy less expensive and more accessible and increase the amount of renewable energy in the United States. He spent seven months working in the office as an Oak Ridge Institute for Science and Education (ORISE) Fellow and is now a technology manager.

“The process of how technologies progress from lab science to usable products is really interesting to me and was important to my quantum research, as quantum technology is trying to make that same leap at the moment,” he said. “In addition, physics has been a wonderful foundation. A good physics education prepares you to pick out the relevant patterns and generalize knowledge really quickly, and it's been a great help in giving me the background to get up to speed on all kinds of other technologies.”

Eldredge knew early on in his studies that he was interested in finding a science policy job to align with his interests in climate, renewable energy and technology development. 

“I really wanted to shift gears from my academic work into something more climate focused, and the ORISE fellowship provided a great opportunity.”

During his time at Maryland, Eldredge co-authored nine publications, including three first-author papers published in the journals Physical Review A and Physical Review Letters. 

“I’m proud to say that two of Zach’s papers are the highlights of my own research over the past few years,” said Alexey Gorshkov, Eldredge’s advisor who is an adjunct associate professor in the Department of Physics and a physicist at the National Institute of Standards and Technology. “In fact, these two papers are so promising that we filed patents for the corresponding ideas, all having to do with the harnessing of the peculiarities of quantum mechanics for technologies such as powerful computing, secure communication and superior sensing.”

In addition to his work in the lab, Eldredge served as president of the social activism group Science for the People UMD and as a member of the Graduate Student Government. 

“Not only is Zach an excellent physicist, he was also an excellent citizen of the department,” said Steve Rolston, professor of physics and department chair. “He was one of the most active members of our self-organized graduate student committee, which strives to make graduate school as positive an experience as possible.” 

Eldredge also participated in public outreach activities, such as the American Physical Society’s Congressional Visits Day, the USA Science & Engineering Festival, and UMD’s Maryland Day. 

“I felt I had a duty as a publicly funded scientist at a major public university to reach out and talk to people, because the knowledge I gained there belongs to everyone,” Eldredge said. “When we discover amazing things, it is on us to communicate about them to the public.”

Fifth Edition of “Exploring Quantum Physics” to Launch on Coursera

Charles Clark and Victor Galitski will launch the fifth edition of their Coursera class on quantum physics Jan. 20, 2020. Alireza Parhizkar, a UMD graduate student will serve as teaching assistant.

“The course begins by establishing the conceptual grounds of quantum mechanics and promises an exciting journey,” says Parhizkar, who joined Galitski’s research group in the summer of 2019. “It fulfills this promise by immersing the learner in advanced subjects of quantum physics, like superconductivity and path integrals, and illustrating them with colorful exercises.”   coursera cats bannerTwo JQI Fellows will launch the fifth edition of "Exploring Quantum Physics" on Coursera Jan. 20.

The free course, titled “Exploring Quantum Physics,” explains topics in quantum physics at a level appropriate for an advanced undergraduate or beginning graduate student. The previous four editions had a total of about 100,000 enrollees, with roughly 2,000 people completing the course. “That’s a good number for a massive open online course, or MOOC,” says Clark, who is an Adjunct Professor of Physics, a Fellow of the Joint Quantum Institute (JQI), and a Fellow at the National Institute of Standards and Technology in Gaithersburg, Maryland. Clark adds that the new edition of the course has a revised grading system as well as updated homework and exam questions.

“Exploring Quantum Physics” consists of eight weeks of video lectures, with a number of five- to fifteen-minute videos per week. The videos include voluntary ungraded quizzes, which automatically pause the presentation so that students have an opportunity to answer relevant questions. There are also weekly homework assignments—some will include reading historical papers by influential early quantum scientists such as Albert Einstein and Niels Bohr—as well as a final exam. “We tried to strike a balance between providing a historical perspective on the early development of quantum physics and modern concepts,says Galitski, who holds the Chesapeake Chair of Theoretical Physics at the University of Maryland (UMD).

An advantage of MOOCs is that the course material is available to anyone, including some students who are younger than traditional undergraduates. Khadija Niazi and her twin brother Muhammad, who grew up in Pakistan, were 13 years old when they enrolled in an earlier edition of the course. Khadija, who once spoke about her experience with MOOCs at the World Economic Forum, says that she “thoroughly enjoyed that course [e]specially because of the peer's help and Charles Clark's constant help and encouragement in the forums.” Before beginning the quantum physics course, the twins had completed some introductory physics classes on the site and learned some calculus from videos on YouTube. Muhammad says that they wanted “to get a taste of what lies ahead.”

Both Niazi siblings stayed in contact with Clark after completing the class. Muhammad, who went on to publish his first experimental physics paper in the journal Royal Society Open Science when he was 16, says he will probably take the new edition of the course to solidify his understanding of the content.

Michael Winer, a physics graduate student at UMD, took an earlier edition of the course when he was a 10th grader at Montgomery Blair High School in Silver Spring, Maryland because he hoped to do physics research over the summer. “By far the greatest thing that came out of my taking the course was that I contacted professor Galitski and did research with him for two summers,” Winer says. “This was my first real research experience, and taught me a lot about the scientific process.” That work led Winer to win the Intel Science Talent Search competition in 2015, earning him a prize of $150,000 and a meeting with President Obama.

“Exploring Quantum Physics” is now open for enrollment. To learn more about the course and to see a detailed syllabus, please visit the landing page at Coursera.
