Rochester’s breakthrough in laser science earns Nobel PrizeA University of Rochester graduate of the Institute of Optics and a former faculty member shared the Nobel Prize in Physics this week for work they undertook at the University’s Laboratory for Laser Energetics (LLE).
Donna Strickland, who received her doctorate in optics from Rochester in 1989 and is now a professor at the University of Waterloo in Ontario, and Gérard Mourou, a former engineering professor and scientist at LLE and currently a professor at the École Polytechnique in France, were recognized for their work to develop lasers as a high-powered tool that ultimately opened the door to new medical, scientific, and commercial applications. Known as “chirped-pulse amplification,” or CPA, the work was the basis of Strickland’s PhD dissertation at Rochester.
Strickland is only the third woman to receive the prize in physics, joining Marie Curie (1903) and Maria Goeppert-Mayer (1963). She is the first woman laureate in Rochester’s history.
“We need to celebrate women physicists because we’re out there,” Strickland said today after her prize was announced. “I am honored to be one of those women.”
Mike Campbell, director of the LLE, said Strickland and Mourou have helped shape the direction of research in high-powered lasers of the kind housed at the laser lab.
“The development of chirped pulse amplification by Gérard and Donna has created numerous new applications in science and industry and has catalyzed research around the world in high peak power lasers,” he said. “The research that led to the Nobel was conducted at the Laboratory for Laser Energetics and highlights the quality and innovation that has long characterized the University’s contributions to optics and laser science. All of us extend our sincere congratulations to Gérard and Donna for their pioneering and impactful research.”
In 1985 Mourou and Strickland demonstrated what has been described as a stunning advance in laser power, with a table-top terawatt laser, or “T-cubed laser.” Until then, the peak power of laser pulses was limited because of the serious damage the pulses caused to the material used to amplify them. Mourou and Strickland worked together to overcome the problem, developing the groundbreaking CPA technique, which involves three steps:
- Stretching the laser pulse thousands of times
- Amplifying the pulse in a laser material without damaging it
- Recompressing it in time back to its original duration
The breakthrough paved the way for creating very short and very intense laser pulses lasting only a fraction of a second, making it possible to build more compact and precise laser systems. The CPA technique has been used in a variety of applications, from Lasik eye surgery to the manufacturing of materials used in smartphones.

University selected as Center of Excellence in Parkinson's DiseaseThe University has been selected as a Morris K. Udall Center of Excellence in Parkinson’s Disease Research by the National Institute of Neurological Disorders and Stroke (NINDS). The new $9.2 million award will bring together researchers from industry and multiple academic institutions to focus on the development of digital tools to enhance understanding of the disease, engage broad populations in research, and accelerate the development of new treatments for Parkinson’s disease.
“We are currently in the midst of a Parkinson’s pandemic,” says neurologist Ray Dorsey, director of the Center for Health + Technology (CHeT) and principal investigator of the new UR Udall Center. “From 1990 to 2015, the number of individuals with Parkinson’s disease globally has doubled and absent change will double again in the coming generation. . . .The medical community must develop new approaches to better understand this complex disease, expand access to specialized care, and increase the speed and efficiency in how we bring new treatments to the market.”
The new UR Udall Center will undertake research using mobile technologies such as smartphones, wearable sensors, and telemedicine to expand the reach of research and to develop objective measures of the disease in real-world settings.
The NINDS funding for the Udall Center at URMC will support four research programs:
- A team led by Karl Kieburtz and Charles Venuto is partnering with GNS Healthcare and Origent Data Sciences to develop advanced machine learning tools to create models that identify and predict the progression of the disease and the potential impact of new therapies to help researchers better understand and potential anticipate the outcomes of clinical trials.
- Bob Holloway, Ruth Schneider, and fellow investigators are partnering with 23andMe to identify individuals across the country with a rarer inherited form of Parkinson’s disease – characterized by a mutation in the LRRK2 gene – and will follow study participants via telemedicine for four years in an effort to better understand the progression of the disease.
- Suchi Saria, with Johns Hopkins University, will partner with researchers at URMC, Aston University in the UK, and Sage Bionetworks to develop a successor to the mPower smartphone application that enables participants and researchers to assess features of the disease on smartphones.
- Dorsey will collaborate with Ehsan Hoque and Gaurav Sharma of the Goergen Institute for Data Science, URMC neurologists Jamie Adams and Chris Tarolli, and researchers at MIT, the University of Michigan Udall Center, Intel, and MC10 to develop and evaluate several remote monitoring and wearable technologies that will help researchers more precisely understand how Parkinson’s disease affects individuals beyond what is observed when patients visit the clinic, but also in their homes and daily lives.
“The opportunity to apply technology to study complex health problems like Parkinson’s requires seamlessly integrating smart sensors in participant’s environment and leveraging the massive amount of data that they produce,” says Hoque, an assistant professor of computer science. “The new UR Udall Center represents the novel convergence of medicine and data science which has the potential to unlock new treatments for this disease.”
The four research projects will be supported by an administrative core led by Dorsey, Augustine, and Cynthia Casaceli; a clinical core led by Giovanni Schifitto; and an advanced analytics core that brings together bio-statistical and computer science expertise that will be led by Michael McDermott and Jiebo Luo, a professor of computer science.

Study: Nursing homes pushing patients into rehab at end of lifeA new study finds that high intensity rehabilitation, which may be driven by a desire to maximize reimbursement rates, is on the rise for nursing home patients in the last 30 days of life, indicating that these services may be interfering with appropriate end-of-life care.
“This study raises several concerns and questions regarding the scope and intensity of therapy provided to nursing home residents prior to death,” says lead author Helena Temkin-Greener of the Department of Public Health Sciences. The study appears in the Journal of the American Medical Directors Association. “If it is being driven by a failure to recognize that a resident is approaching end-of-life, then it calls for improving the skills of nursing home teams. If it is being driven by financial considerations then regulatory and policy interventions may be necessary.”
Nursing home Medicare reimbursement rates are based on categories that place patients into resource utilization groups (RUGs) based on the complexity, intensity, and amount of staff time dedicated to their care. Patients who receive high levels of rehabilitation services fall into a category that makes these facilities eligible to collect the highest level of reimbursement for their care.
Recent reports from the Department of Health and Human Services Office of Inspector General (OIG) and the Center for Medicare and Medicaid Services (CMS) have suggested that the volume and intensity of rehabilitation services provided to residents in skilled nursing facilities may be more extensive than warranted and found that billing for these services was on the rise. The OIG has also indicated that this data suggests that some nursing homes may be exploiting the payment system for rehabilitation services in order to “optimize their revenues.”
The authors of the current study analyzed data from 647 nursing home facilities in New York State. Specifically, they focused on residents who had received very high to ultrahigh rehabilitation services – physical, occupational, and speech therapy – during the last 30 days of life. Very high intensity rehabilitation is defined as 520 minutes or greater per week and ultrahigh as 720 minutes or greater, or the equivalent of two hours of rehab per day.
They found that residents receiving ultrahigh rehabilitation had increased by 65 percent between 2012 and 2015 and that most of the rehabilitation therapy residents received was concentrated in the last seven days of life. They also found that there was a significantly higher use of these services in for-profit nursing homes compared to not-for-profit homes.
While the study only included data from New York State, the authors contend that this phenomenon is likely more pronounced in other states, which have lower nursing home regulatory oversight.

Financial woes cause some elderly patients to delay cancer treatmentNearly one in five older patients with advanced cancer have financial problems that may cause them to delay treatment to cover food and housing costs, which leads to stress and poor quality of life, according to new Wilmot Cancer Institute research.
The “financial toxicity” study was conducted at several cancer clinics across the country, involving 542 patients ages 70 to 96, said senior author Supriya Mohile, a geriatric oncology expert and the Philip and Marilyn Wehrheim Professor at Wilmot.
“Our results are striking and important because it’s tapping into a patient population that reflects real world experiences,” Mohile said. “The majority of cancer patients are older, often living on restricted budgets, and do not want to be a burden on their children. Their money has to cover not just cancer-related expenses but other health expenses — such as high blood pressure or diabetes medications — and other costs of living. This is a common scenario and as a society we need to pay attention.”
Asad Arastu, a School of Medicine and Dentistry student with a background in economics, led the research by slicing out a subset of data from a larger, peer-reviewed study on geriatric assessments that Mohile had conducted in the past. They developed an easy-to-use screening tool for patients comprised of three questions: Have you ever delayed medications due to cost? Have you ever had insufficient income in a typical month for food and housing? Have you ever had insufficient income in a typical month for other basic needs?
Patients who answered yes to any of the questions were categorized as experiencing financial toxicity, Arastu said. The goal was to create a screening tool for busy oncologists with content that patients could easily and quickly understand.
On average, patients with financial hardships also scored lower on measurements of anxiety, depression, and quality of life — important factors to consider when caring for these patients because they can impact outcomes, Mohile said.

Introducing a new faculty member
Nancy Chen joins the Department of Biology as an assistant professor, after serving as a National Science Foundation postdoctoral fellow at the University of California, Davis from 2015 to 2018, studying population and evolutionary genetics. Previously, she was a postdoctoral research associate and lab associate at the Cornell Lab of Ornithology.
Chen is an evolutionary biologist who analyzes how different evolutionary forces contribute to genetic variations. Her work integrates genomics and evolutionary genetics with natural history and field biology to study declining populations in the wild. One of her current projects involves developing new statistical methods and applying them to a long-term study of the endangered Florida scrub jay. She received funding from the National Science Foundation for the genome-wide study, which will help answer fundamental questions in evolutionary biology, including whether and how reduced genetic diversity might predict a decline in the species. The work will also help inform conservation strategies for the rare bird.
In 2017, Chen was awarded the American Ornithological Society’s James G. Cooper Young Professional Award. Her work has appeared in several peer-reviewed journals, including Current Biology, Applied Physics Letters, and Genetics. She is dedicated to increasing diversity and inclusion in STEM, and she co-led a women-in-science group at Davis as well as diversity and inclusion programming for the American Ornithological Society.
She received her PhD in ecology and evolutionary biology from Cornell University in 2014.
