To support a broadly shared Graphic Processing Unit (GPU)-enabled high-performance computing cluster for the Institute for Applied Sciences (IALS), computational biophysicist Jianhan Chen, chemistry and biochemistry and molecular biology, with others, recently was awarded a two-year, $415,000 grant from the National Science Foundation (NSF) that will fill what Chen calls “a critical need” for enabling computation-intensive research activities on campus.
Although the UMass system has a traditional shared cluster housed at the Massachusetts Green High-performance Computing Center (MGHPCC) in Holyoke, Chen points out, the current cluster has “minimal GPU capacity” and the campus and IALS need dedicated GPU computing hardware to support their research communities. His co-principal investigators on the project are Erin Conlon, mathematics and statistics, Peng Bai, chemical engineering, Chungwen Liang, IALS director of computational modeling, and Matthew Moore, food science.
“When we put in the grant we solicited comments and surveyed the need from IALS and identified 30 labs that could use it,” Chen explains. “They testified to the need and committed to the cost share with NSF, which will come from IALS, the College of Natural Sciences, College of Engineering, central IT and the Vice Chancellor for Research and Engagement. This is going to be a really unique entity on campus, and it will have far-reaching impact,” he predicts. “It will be busy from the get-go.”
“I think NSF saw how much need and support we have. I want to particularly highlight the important contributions of Chris Misra and John Griffin of IT,” he adds. “They have taken the leadership in providing technical support that’s absolutely critical to me and other principal investigators on campus. Without them and their excellent help, this will not work, period.”
The new cluster, once carefully built up by Griffin, Chen and his co-investigators, will be managed by the IALS Computational and Modeling Core to provide long-term stability for operation and management, serving 250 IALS-affiliated research labs across 27 departments and seven colleges. “The GPU facility offers high-speed single- and double-precision operations as well as extreme parallelism to enhance current activities that contribute to the open science movement,” project leaders state.
It will also contribute to efforts to integrate regional education, outreach, diversity and economic activities, as the GPU facilities will be made available to researchers through Internet2 links and regional computing partnerships at MGHPCC. The researchers predict that the new cluster “will most likely lead to new developments and discoveries including novel GPU-enabled modeling and simulation technologies that may elucidate molecular mechanism of drug delivery, computational design catalysts for renewable energy and chemical synthesis, advanced computational analysis tools for next generation informatics and big data, and improved understanding of risk and resistance to breast cancer.”
A gift of $1.25 million from Mahoney Family, over five years to the College of Natural Sciences at UMass Amherst, will significantly expand the reach of the Integrated Concentration in Science program (iCons) by recruiting more faculty, providing more mentors for STEM students and funding the spread of the pioneering iCons program to other higher education institutions.
“Interdisciplinary solutions have always been the key to solving the tough problems,” says Richard J. Mahoney, a longtime UMass supporter whose family is providing the increased funding for iCons. “Although academic institutions are often stuck in their silos in the way they teach and operate, I’m happy to see that UMass Amherst is pioneering a more integrated real-world education for its students. I was present at the creation of iCons, and having watched the program grow, I've seen first-hand its impact on students and their future in science.
Mahoney’s family, including Barbara M. Mahoney ’55, William E. Mahoney ’55, and Robert M. Mahoney ’70 and Kathleen S. Mahoney ’70 are longtime supporters of the sciences at UMass Amherst.
“The iCons program has invented a revolutionary approach for teaching that fosters innovation, integration and impact,” said UMass Amherst Chancellor Kumble R. Subbaswamy. “This generous gift from the Mahoney family enables UMass to provide national leadership in this 21st century way of learning.” Robert S. Langer, the David H. Koch Institute Professor at MIT and a member of the UMass iCons Advisory Board, observed, “The UMass iCons program is unique across the USA. From my experience, iCons students have the leadership skills to ask the right questions, and the technical skills to find the right answers.”
Mahoney’s gift supports three separate funds that will dramatically broaden the impact of the UMass iCons program: the Directorship Fund, the Instructional Fund and the Evolution Fund. The Directorship Fund allows UMass Amherst to attract a world-class educator and researcher in STEM to direct the UMass iCons program. The director will be responsible for recruiting top-notch iCons faculty and partnering with companies and other universities to spread the program’s impact. Scott Auerbach, professor of chemistry at UMass Amherst and the iCons program’s founding director, is the first person to occupy this position as the newly appointed Mahoney Family Sponsored Executive Director. Auerbach has published two books and over a hundred articles on nanotechnology and clean energy, and has been at the forefront of educational innovation in STEM.
Assistant professor Mingxu You, chemistry, recently received a five-year, $1.9 million NIH Maximizing Investigators’ Research Award (MIRA) to fund his research in developing new tools – DNA-based probes – to quantify intercellular mechanical forces and understand a variety of mechano-sensitive cell signaling events at the molecular level.
As he explains, intercellular forces are critical regulators in many physiological and pathological processes, but scientists have until recently lacked the tools and approaches to characterize these mechanical events. “It is a whole new way to understand growth, division, intercellular motion and interaction,” You says. Cells are usually touching each other or a substrate, pushing and pulling each other to work together as a tissue, an organ and at the whole body level, he adds. But these forces are so tiny and ever-changing, it is very hard to see how cells are physically communicating with each other, for example, during development, cell differentiation, normal physiological and various disease processes.
The You Lab, which includes postdoctoral researcher Bin Zhao and chemistry Ph.D. students Yousef Bagheri and Puspam Keshri, will team with biologists Barbara Osborne and Tom Maresca, Lisa Minter of veterinary and animal sciences and Yubing Sun, mechanical and industrial engineering, to further develop these DNA-based tools to visualize, monitor and quantify such cellular forces. You says, “In the near future, people will be able to apply these tools broadly to depict the basic principles of tissue morphogenesis, growth, and homeostasis. They will serve as a critical foundation for developing novel strategies in tissue engineering, regenerative medicine, immunotherapy and cancer treatment.”
Specifically, You says, “We are interested in the Notch signaling pathway. It’s widely conserved in most cells and organisms, very common to find, and it’s interesting because it’s really simple. There are only five Notch ligands and four Notch receptors but they regulate quite a diverse range of downstream functions,” he adds.
Peter Reinhart, director of the University of Massachusetts Amherst’s Institute of Applied Life Sciences (IALS), has announced that six campus research teams have been named recipients of the first Manning/IALS Seed Grants. The awards will support next steps in their research such as proof-of-concept studies and business development, fundamental research into new products, technologies and services to benefit human health and wellbeing.
Earlier this year, alumnus Paul Manning and his wife, Diane, committed $1 million through their family foundation to establish the Manning Innovation Program. It provides three years of support in advancing a robust and sustainable pipeline of applied and translational research projects from UMass Amherst.
The seed grants announced this week were awarded after a competitive process that narrowed 35 teams to six winners. Faculty researchers will receive seed funding of $100,000 each over three years, along with business training and mentorship from IALS, the College of Natural Sciences, the Berthiaume Center for Entrepreneurship and the Isenberg School of Management, among others.
Chemistry’s winning team leaders and their projects are:
• Jeanne Hardy, chemistry, “Development of Potent Zika Virus Protease Inhibitors”
• S. “Thai” Thayumanavan, chemistry, and Steve Faraci, “Pre-Clinical efficacy evaluation of liver-targeted, thyromimetic-encapsulated IntelliGels for the treatment of non-alcoholic steatohepatitis (NASH)”
Steve Acquah, adjunct research professor of chemistry and Digital Media Lab coordinator at the W.E.B. Du Bois Library, spoke at the dedication of the Florida State University (FSU) Chemical Sciences Laboratory Auditorium in honor of Nobel Prize winner Sir Harold Kroto on Friday, Oct. 4.
Acquah, the former manager of the Kroto Research Group at FSU, received his doctorate at the University of Sussex, England, under the supervision of Kroto. Acquah gave a talk titled “Beyond the Possible” that highlighted his work at UMass Amherst and showed how Kroto’s legacy lives on through his work at the UMass Libraries Digital Media Lab, his chemistry laboratory and the Global Educational Outreach for Science Engineering and Technology (GEOSET) initiative.
Florida State named the chemistry auditorium after Kroto – who died in 2016 – and the university’s department of chemistry and biochemistry placed an art piece of a buckyball designed by FSU’s Master Craftsman Studio in the foyer outside the auditorium. The buckyball was unveiled by Kroto's widow, Lady Margaret Kroto.
The day after the dedication, a buckyball workshop for children was led by Jonathan Hare, who was a member of the original team that included Kroto that isolated C60. In the workshop the children learned about the life of Richard Buckminster Fuller and Kroto before building their own model of a buckyball. Acquah said, “The buckyball workshop was one of Harold Kroto’s favorite ways to get children involved in the sciences and hands-on activities.”
Acquah, who is also a 2019-20 UMass Sustainability Curriculum Fellow, co-instructs the “Makerspace Leadership and Outreach” course with Charlie Schweik, School of Public Policy, at the All-Campus Makerspace. “The maker movement is exactly what Sir Harold Kroto would have been passionate to support,” Acquah says. “He always spoke about how owning a Meccano set helped him develop the skills he would use for research. The students in the class exemplify the creative talents at UMass Amherst.”
112th Metawampe Hike Sunday, November 3, 2019
The 112th annual Metawampe Hike will be held Sunday, November 3 starting at noon (12PM) from the former Ashram parking lot (to the right of the white picket fence and behind a barrier of trees) on Route 63 (#438) about 5 miles north of the North Amherst traffic lights (near Cumberland Farms). Hikers meet at 11:30 AM at the corner of Park, Claybrook and North Mountain Roads in Sunderland (for directions use 98 Claybrook Road, Sunderland). [SAME AS LAST YEAR] This is the location where the Metawampe Hike trail exits the woods. At 11:45AM we will carpool and drive a minimum number of the cars to bring all hikers to Ashram to begin the noon hike. Some may wish to meet us at Ashram at noon. At the end of the hike, using the cars left in Sunderland at the meeting point (also the endpoint of the hike) we will return to Ashram to retrieve the cars driven there earlier. The hike will be held rain or shine unless conditions are so treacherous as to be unsafe, in which case I will notify the e-mail list of hikers. Hikers should plan to bring whatever clothing, supplies, snacks, or water they need, nothing will be supplied. After the hike we will reconvene at a mutually agreed upon venue for needed libation and nourishment. This year we will not be holding the church supper, an event we do biannually in even years– next in 2020. The hike continues to be an annual event held on the first Sunday in November, the same Sunday when Daylight Saving Time ends! We realize that no date will be suitable for everyone but encourage all those who can make it to join us for this university tradition that dates back to 1908. The hike is from point to point and is of moderate difficulty, is about 5 miles in length, and usually takes about 3 hours or so, depending on conditions. Friends, spouses, children, pets - all are welcome. If you have any questions or would like a map showing the meeting point and hiking route contact Dave Adams, at email@example.com.
Graduate students Ali Kiaghadi and S. Zohreh Homayounfar, with their professors Trisha L. Andrew, a materials chemist, and computer scientist Deepak Ganesan, will introduce their health-monitoring sleepwear “phyjamas” at the Ubicomp 2019 conference this week in London, U.K.
As Andrew explains, “The challenge we faced was how to obtain useful signals without changing the aesthetics or feel of the textile. Generally, people assume that smart textiles refer to tightly worn clothing that has various sensors embedded in it for measuring physiological and physical signals, but this is clearly not a solution for everyday clothing and, in particular, sleepwear.”
“We expect that these advances can be particularly useful for monitoring elderly patients, many of whom suffer from sleep disorders,” says Andrew. “Current generation wearables, like smartwatches, are not ideal for this population since elderly individuals often forget to consistently wear or are resistant to wearing additional devices, while sleepwear is already a normal part of their daily life. More than that, your watch can’t tell you which position you sleep in, and whether your sleep posture is affecting your sleep quality; our Phyjama can.”
This work was enhanced by Ganesan and Andrew’s affiliation with UMass Amherst’s Institute of Applied Life Sciences (IALS), which focuses on translating life science research into products that improve human health. Director Peter Reinhart at IALS says, “It’s exciting to see the next generation of wearable technology that is zero effort and addresses the issue of comfort and unobtrusiveness head-on. The data generated by fabric-based sensors have the potential to improve health and well-being, and could possibly contribute to the early diagnosis of multiple disorders.”
Sankaran ‘Thai’ Thayumanavan was appointed as a Distinguished Professor by the Board of Trustees. The title Distinguished Professor is conferred on select, highly accomplished faculty who have already achieved the rank of professor and who meet a demanding set of qualifications.
Chancellor Kumble Subbaswamy and Provost John McCarthy wrote,“Professor Thayumanavan’s research is focused on the design and synthesis of supramolecular assemblies with novel functions that advance chemical, materials and biological sciences in applications that range from molecular recognition to drug delivery to renewable energy. His work is distinguished by a focus on dynamics, creating materials with the ability to respond across multiple length and time scales and following exposure to stimuli including pH, temperature, and light.
He currently has grants that run several years into the future: an NIH grant with a 1.0 percentile score (amazing), an NSF grant as a CCI, an ARO MURI grant, and several other federal funded applications that are still running (an NIH R01, industrial sponsors) and many previous grants. This alone shows the longevity of his program and argues strongly for continued productivity.
Prof. Thayumanavan’s research program is characterized by prolific excellence. Since promotion to Professor in 2008, Prof. Thayumanavan has published over 120 articles, with more than 30 in the top tier of chemistry journals as lead author. In the same time period, he has garnered more than $26 million in external support. He has given more than 100 presentations on his research since 2008, including keynote addresses and prestigious lectures such as the Nanqiang lecture in Xiamen University (2014), and he was elected as a Fellow of the American Association for the Advancement of Science in 2011.”
A team led by UMass chemist Dhandapani Venkataraman, “DV,” and electrical engineer Zlatan Aksamija, reported in Nature Communications on an advance they outline toward more efficient, cheaper, polymer-based harvest of heat energy. “It will be a surprise to the field,” DV predicts, “it gives us another key variable we can alter to improve the thermo-electric efficiency of polymers. This should make us, and others, look at polymer thermo-electrics in a new light.” Aksamija explains, “Using polymers to convert thermal energy to electricity by harvesting waste heat has seen an uptick in interest in recent years. Waste heat represents both a problem but also a resource; the more heat your process wastes, the less efficient it is.”
DV and his chemistry PhD student Connor Boyle, with Aksamija and his electrical engineering Ph.D. student Meenakshi Upadhyaya worked in what DV calls “a true collaboration,” where each insight from numerical simulations informed the next series of experiments, and vice versa. The team turned to chemist Michael Barnes, a co-author on their recent paper, who used Kelvin Probe Force Microscopy to probe the dopants at the nano level and show that clustering is indeed present in polymers doped at room temperature, but not at higher temperatures.
The findings should provide a new path for designing more efficient polymers for thermo-electric devices. DV notes that until now, chemists and materials scientists have been trying to organize polymers to be more like the inorganics, “nicely aligned and very regular, which is difficult to do,” he adds. “It turns out that this may not be the way to go; you can take another road or another approach. We hope this paper provides a basis to move polymer-based thermo-electrics forward.”
The American Chemical Society showcased the ‘Phyjama’ developed by Trisha L. Andrew, chemistry, and presented at the ACS Spring 2019 National Meeting & Exposition. The ‘smart’ pajamas include monitors to help track sleep patterns, and could be available to consumers within a few years.
"Our smart pajamas overcame numerous technical challenges," says Trisha L. Andrew, Ph.D., who led the team. "We had to inconspicuously integrate sensing elements and portable power sources into everyday garments, while maintaining the weight, feel, comfort, function and ruggedness of familiar clothes and fabrics. We also worked with computer scientists and electrical engineers to process the myriad signals coming from the sensors so that we had clear and easy-to-understand information."
Getting enough quality sleep can help protect people against stress, infections and multiple diseases, such as heart and kidney disease, high blood pressure and diabetes, according to the National Institutes of Health. Studies have found that quality sleep also increases mental acuity and sharpens decision-making skills. Yet most people do not get enough sleep — or the right kind.
"Vachet’s interdisciplinary research program is at the interfaces of analytical, biological, and materials chemistry. He and his research group develop and apply new methods based on mass spectrometry to tackle biomedically important problems that are difficult to address with existing tools. His work has elucidated the molecular details associated with protein amyloid fibril formation, which is a special type of protein aggregation that occurs in numerous human diseases. His research has also led to the development of sensitive new methods to track nanomaterial drug delivery vehicles in biological systems, facilitating the creation of better therapeutics with fewer side effects."
Award recipients are chosen by committees chaired by designees appointed by Dean Tricia Serio, including past recipients. Dean Serio, associate dean for research and innovation Mark Tuominen, and department representatives congratulated the winners, each speaking briefly about their experiences.
"Vicki’s performance has been outstanding by any measure. She is considered the go-to person for many issues, including financial, compliance, and more. She is intelligent, efficient, always cheerful, and can be relied upon to solve any problem. She is indispensable and irreplaceable in that she almost single-handedly oversees all financial operations of our department, and is, in fact, the only person who fully understands them. " Serio emphasized her gratitude to the award winners for their extraordinary work, presenting them as leaders for the college. “Their tremendous work continues to foster student achievement, demonstrate excellence, and build a more inclusive environment,” she said. “They are wonderful role models for us all.” Friends, family, and colleagues gathered at a reception and awards ceremony May 14 for this year’s recipients of the CNS Outstanding Achievement Awards. The awards recognize faculty, staff and students who have made important contributions to their discipline, department, college and university.
