At 2022 Commencement, Graduates Lauded as Values-Driven Innovators

The Katz School of Science and Health recently conferred 123 master’s degrees to graduating students whom Dean Paul Russo called “values-driven practitioners” for their academic integrity and commitment to the compassionate care of others.

“You stand for truth, reflected in your scholarship and applied in your practice. You are champions of a life built on values—respecting the worth of every individual and their right to care and full participation in life—economically and socially,” said Dean Russo at the school’s sixth commencement exercises on May 16. “You are compassionate practitioners who bring your know-how in science, technology and health to transform our world for the better and move history forward. You are people of integrity, who when moving science to practice will never sacrifice the invaluable in the pursuit of the valuable.”

An Immigrant's Chance Encounter with Katz Official Leads to IBM Job

The very act of immigrating is entrepreneurial, a self-selected risk taken by an individual to better one’s circumstances. It’s a mindset that served Jesus Olivera well at the Katz School of Science and Health. Jesus, who was recently awarded a master’s degree in Data Analytics and Visualization, defied his family’s wishes to pursue a career in Puerto Rico by immigrating to New York City in 2012 at the age of 22.

Jesus said plunging into a new culture gave him “strength and focus” because he not only needed to learn English, he had to adjust to the frenetic pace of the city and corporate life. “Everything you do in life requires a level of effort and hard work, so I didn’t think my experience was different from anyone else’s,” he said.

Cybersecurity Graduate Trades in Police Cap for Black Hat

Employers in the internet era have had to become more creative in finding people to guard the digital gates to their computer systems unwittingly left open, exposing precious company data. This has created the need for a whole new class of virtual sleuths, called penetration testers, to simulate attacks on their systems to find and fix vulnerabilities that could be exploited by a real attacker.

One of them is Kevin Suckiel, who recently was awarded a master’s degree in cybersecurity from the Katz School of Science and Health. He recently landed a prized job at the prestigious Big Four consulting firm Ernst and Young that has him donning the blackest of hats to crack the networks of his company’s clients.

STEM, Health Programs Help Fuel YU Surge in Rankings

Yeshiva University surged to 68th among Best National Universities in the latest U.S. News & World Report rankings on best colleges, rising from 76th in 2021 and 97th in 2020.

The university also placed 33rd in the Best Value Schools category, up from 54th last year. This distinction recognizes the colleges and universities that offer students the best value based on academic quality and average cost of attendance.

President Ari Berman attributed the climb to the “strong execution” of the university’s long-term strategy of growth and investment in STEM and health programs, among other factors. Provost Selma Botman called the ranking an “impressive achievement” that was made possible by excellence in teaching and the introduction of new academic programs.

“The growth in Yeshiva University’s prestige as a research university is directly linked to the rising fortunes of the Katz School Science and Health,” said Dean Paul Russo. “We are advancing scholarly knowledge and transforming lives through pioneering research, citywide initiatives, new technologies and innovative clinical diagnostics.”

OT Researcher Takes Children's Playtime Seriously

The amount of playtime that children get during a school day has been an ever-present concern among parents, educators and public health officials. Parents who grew up outside worry that their children are missing out on something special and important to their lives. Educators fret that play, an essential part of learning, is being squeezed out by academic programming. And public health officials warn of the health consequences for young people who are deprived of exercise.

“The engagement in play and playful interactions is essential to children’s development, as well as physical and mental health,” said Dr. Amiya Waldman-Levi, a clinical associate professor in the Katz School’s Occupational Therapy Doctorate program.

A training program proposed by Dr. Waldman-Levi and Dr. Lola Halperin of Sacred Heart University in Bridgeport, Conn., will prepare teachers serving children who are facing adversity to use play and playfulness as vehicles for fostering children’s growth, with the long-term goal of promoting occupational justice.

Speech Pathology Adds Online Master's Degree

The Katz School’s M.S. in Speech-Language Pathology has received approval for a distance education program from the New York State Education Department. It will begin accepting students in the fall of 2022.

The curriculum of the 55-credit program is identical to the residential program, being one of just a few programs in the country specializing in the medical aspects of speech-language pathology.

It’s fully online, has no on-campus requirement, and offers both a full-time (five-semester) and part-time (eight-semester) plan of study. Students will meet weekly with their professors for live online instruction and complete interactive asynchronous learning prior to class.

The program takes a holistic and multidisciplinary approach to diagnosing and treating speech, language, swallowing and communication cases for people of every age. Upon graduation, students are prepared to apply for certification from the American Speech-Language Hearing Association (ASHA), as well as state licensure.

“We are excited to expand our ability for students to take advantage of our program’s holistic approach to patient care and inclusive coursework so they may enter the workforce as qualified allied health professionals,” said Dr. Marissa Barrera, program director and assistant dean of health sciences.

Study Quantifies Filtration System's Benefit

The incidence of life-threatening diarrhea plummeted among residents in several rural villages in Ghana over a five-month period after they began using water purified with repurposed hemodialyzers, according to a study published by a Katz School professor in Scientific Reports in July.

“This is a major public health outcome particularly since diarrhea is well known to be associated with deleterious consequences, such as acute kidney injury and death particularly in younger children and the elderly,” said Dr. Jochen Raimann, who teaches in the Biotechnology Management and Entrepreneurship program.

Dr. Raimann, who is a board member of Easy Water for Everyone, the nonprofit organization which funded the study, and his colleagues collected data between February and December 2018 in four rural communities in the Ada-East district of Greater Accra Region in Ghana before and after the implementation of the NUF500, a hemodialyzer membrane filtration system manufactured by the Israeli company NuFiltration.

“The filtration system used in this study was clearly associated with a substantial reduction in the incidence of self-reported diarrhea compared to the prior period and compared to a control group without the system,” said Dr. Raimann.

An analysis of monthly household surveys found that the risk of developing diarrhea among the 400 villagers who consumed purified water declined by 72 percent after the installation of the filtration system. The incidence of diarrhea fell to 0.05 cases per person per month from 0.18 compared to the four control villages where the number of cases declined to 0.08 ppm to 0.11.

“This translates into an incidence rate ratio of 0.38, which is a remarkable public health effect of a 62-percent risk reduction relative to that in the control villages,” said Dr. Raimann, citing a follow-up paper published recently in Water Supply. “This is achieved with the use of a device that is very simple to use and tremendously cost-effective.”

In many countries, contaminated water is the underlying cause of acute gastrointestinal disease, and recent international research efforts by the International Society of Nephrology have shown that diarrhea is the leading cause of acute kidney disease in developing countries and contributes to high mortality rates among weaned children younger than 5 years of age and the elderly.

The World Health Organization and the World Bank estimated that 1.1 billion people worldwide have access only to unsafe drinking water. Eighty-eight percent of all diarrheal diseases, according to the WHO, are caused by the consumption of unsafe drinking water and lack of adequate sanitation. In the villages that were studied by Dr. Raimann’s team, surface water from ponds, creeks and rivers polluted by coliform bacteria (Escherichia coli) and viral pathogens was the main source of drinking water.

The study, “Public Health Benefits of Water Purification Using Recycled Hemodialyzers in Developing Countries,” was conducted with the approval and support of Ghana Health Services and the federal and local government. The researchers provided villages with filtration systems containing re-sterilized hemodialyzers repurposed from their use in kidney dialysis. The devices are capable of producing up to 132 gallons of water per hour free of bacteria and viruses for domestic use.

“The remarkable aspect of this filtration system,” said Dr. Raimann, “is that not only does it not require electricity to produce clean drinking water, it’s built of hemodialyzers that were used in clinical therapy of renal failure patients and saved by re-sterilization from going to waste.”

He said the NUF500 filtration system can help achieve “Sustainable Development Goal-6,” one of 17 goals established by the United Nations General Assembly in 2015, to “ensure availability and sustainable management of water and sanitation for all” by 2030.

“The use of repurposed hemodialyzers that had already saved lives once in kidney dialysis treatment can again serve as an affordable means of water purification, saving lives all over the globe,” he said.
