Richard (Dick) Stein, 95, passed away June 21, 2021. He joined the Department of Chemistry in 1950 and was central to the development of polymer science research and the creation of the Department of Polymer Science and Engineering. Over the course of his career Stein mentored more than 140 master’s and doctoral candidates.
Stein was a pioneer, wanting to leave the world a better place, and his post-retirement focus was global climate change. He established the Richard and Judy Stein Endowed Fund for Sustainability and Renewable Energy, the first fund on campus to support the university’s efforts on sustainability.
Stein developed the university’s first advanced physical chemistry courses in quantum mechanics, statistical mechanics, and polymer science, and initiated graduate research in the study of the structure-property relationships of polymers using light and particle scattering.
He is also credited with revolutionizing research funding management at the campus in the 1950s. Grant dollars from federal agencies went directly to the state treasury, not the Amherst campus. With Dean of Science Charles Alexander, Stein helped pass a bill that allowed research money to come directly to the campus.
Stein became Commonwealth Professor, and in 1961 he founded both the Polymer Research Institute and the Research Computing Center. In 1980, the chemistry department awarded him the Charles A. Goessmann Chair in Chemistry and provided three new professorial positions in polymer science and engineering. In the 1990s he was inducted into the National Academy of Sciences and the National Academy of Engineering.

“What our team has done,” explains Khushboo Singh, a graduate student in the chemistry department and one of the study’s lead authors, “is to combine the advantages of biologics and ADCs and address their weaknesses. It is a new platform for cancer therapy.”
A team of researchers at the Center for Bioactive Delivery at the University of Massachusetts Amherst’s Institute for Applied Life Sciences has engineered a nanoparticle that has the potential to revolutionize disease treatment, including for cancer. This new research, which appears today in “Angewandte Chemie,”combines two different approaches to more precisely and effectively deliver treatment to the specific cells affected by cancer.
Two of the most promising new treatments involve delivery of cancer-fighting drugs via biologics or antibody-drug conjugates (ADCs). Each has its own advantages and limitations. Biologics, such as protein-based drugs, can directly substitute for a malfunctioning protein in cells. As a result, they have less serious side effects than those associated with traditional chemotherapy. But, because of their large size, they are unable to get into specific cells. ADCs, on the other hand, are able to target specific malignant cells with microdoses of therapeutic drugs, but the antibodies can only carry a limited drug cargo. Since the drugs are more toxic than biologics, increasing the dose of ADCs increases the risk of harmful side effects.
The team’s approach depends on a nanoparticle the team engineered called a “protein-antibody conjugate,” or PAC. “Imagine that the antibodies in PACs are the address on an envelope,” adds Sankaran “Thai” Thayumanavan, distinguished professor in chemistry and interim head of biomedical engineering at UMass, “and that the cancer-fighting protein is the contents of that envelope. The PAC allows us to deliver the envelope with its protected treatment to the correct address. So, safer drugs are delivered to the right cell—the result would be a treatment with fewer side effects.”
"Skin-Inspired Organic Electronics"
Mingxu You, assistant professor of chemistry at UMass Amherst, has been awarded one of 16 $100,000 Teacher-Scholar unrestricted awards from the Camille and Henry Dreyfus Foundation. But when the award e-mail came later that day, he knew it was true. “It was quite an unexpected, and very welcome, surprise” You says. “We are thrilled,” says Rick Metz, head of the chemistry department, “that Mingxu’s dynamic research and teaching have received this recognition.”
The Dreyfus Foundation’s Teacher-Scholar award goes to a handful of early-career chemists who “have each created an outstanding independent body of scholarship, and are deeply committed to education.” You is clearly both. Though he’s early in his career, he’s already authored or co-authored nearly 80 academic articles, and his lab is a hive of activity: it currently hosts ten graduate and five undergraduate students. In the past four years alone, he’s guided 15 undergrads, two postdocs, and five research fellows through advanced chemistry research, and in doing so is helping to introduce the next generation to the joys of chemistry. “The undergrads are getting real training,” say You. “They quickly learn what we’re doing in our lab, and they make real contributions to our experiments.”
For You, there’s a seamless connection between the classroom and the lab. “When I teach undergraduates, I need to revisit the basics of chemistry, and I’m always discovering insights that I had passed over when I was a student.” When one of You’s students joins his lab, they not only bring their classroom education with them, but return to class bearing some of what they discovered in the lab.
“I’d like to thank the hard work of everyone in the You Lab,” says You, for whom UMass has been an ideal research and teaching home. “The environment in the chemistry department is really supportive of early career scholars.”
Each year, the College of Natural Sciences honors its faculty, staff, and student leaders who have made important contributions to their discipline, department, college, and university by presenting them with the Outstanding Achievement Awards. Recipients are nominated by colleagues within the college and chosen by committees chaired by designees appointed by Dean Tricia Serio, who may include past awardees. Of this year’s recipients, Dean Serio remarked, “These leaders continue to enrich our college community with their exceptional work. I am tremendously grateful for their efforts to demonstrate academic excellence, enhance the student experience, and create a more inclusive and accessible learning environment.”
Robert “Bob” Sabola, Instrumentation Engineer, Chemistry was a recipient of the award and commented, "Truly a surprise, maybe even a little shocking, when I learned that I was chosen as a recipient of the CNS Outstanding Achievement Award. It is an honor for me to receive this award. Thank you to all the faculty, staff, and students who contributed to this nomination. I always had the thought that my job is to make the lives of those who are on campus a little bit easier. It’s easy to do when you enjoy what you do for work. As always, it has been a pleasure and joy to have worked for you and with you throughout the years. What more can I say other than thank you."
The 2021 and 2020 CNS Outstanding Achievements Awards Ceremony were combined this year and held virtually. Here is a recording of the event.
UMass Amherst Chemistry participates in the ACS Bridge Program which aims to diversify the graduate student population in the chemical sciences. The mentorship program, part of the NSF INCLUDES Alliance: Inclusive Graduate Education Network (IGEN), provides additional pathways for Black, Latino, and Indigenous students to receive doctoral degrees.
Prospective students are considered by all of the 22 participating institutions by submitting one application.
Prof. Michael Knapp, ACS Bridge Program leader for UMass Amherst Chemistry, commented on the success of the program, “I think we’ve all worked with people where they really don’t need or don’t want a lot of hand-holding. But making sure that the trampoline is there when you’re on the high wire is really important so that if you fall off, you can bounce back.”

UMass Chemist Eric Strieter and his lab group have discovered how an enzyme known as UCH37 regulates a cell’s waste management system, a result they found “incredibly surprising.”
Strieter says, “It took us eight years to figure it out, and I’m very proud of this work. We had to develop a lot of new methods and tools to understand what this enzyme is doing.”
As he explains, a very large protease called a proteasome is responsible for degrading the vast majority of proteins in a cell; it may be made up of as many as 40 proteins. It has been known for more than 20 years that UCH37 is one of the regulatory enzymes that associates with the proteasome, he adds, “but no one understood what it was doing.” It turns out that the crux of the whole process, he adds, is how complicated modifications in a small protein called ubiquitin can be.
Writing this week in Molecular Cell, he and first author and Ph.D. candidate Kirandeep Deol, who led and conducted the experiments, with co-authors Sean Crowe, Jiale Du, Heather Bisbee and Robert Guenette, discuss how they answered the question. The work was supported by the NIH’s National Institute of General Medical Sciences.
This advance could eventually lead to a new cancer treatment, Strieter says, because cancer cells need the proteasome to grow and proliferate.
Project leader and chemistry professor Dhandapani “DV” Venkataraman, is one of five researchers from a campus group that has been selected to receive a one-year, $100,000 grant from the National Science Foundation’s “10 Big Ideas for Future NSF Investments” series to conduct a series of national workshops to identify research challenges associated with transitioning to an equitable and sustainable energy system.
The grant is the second this year from the National Science Foundation (NSF) to researchers at UMass for a similar purpose, evidence of a growing worldwide interest in developing sustainable energy systems that consider and even prioritize the resources and needs of all communities.
“A transition toward a less carbon-intensive energy system is underway globally,” Venkataraman points out. “The challenge is to envision how the energy system might evolve in a way that is consistent with resources and needs.”
Further, he explains, “When we are thinking about the emerging energy technologies landscape, we need to incorporate equity as an intrinsic design component. This requires energy scientists, equity scholars and other stakeholders who normally work independently to come together and identify the priorities and needs.”
