Tim Lodge graduated from Harvard in 1975 with a B.A. cum laude in Applied Mathematics. He completed his PhD in Chemistry at the University of Wisconsin in 1980, and then spent 20 months as a National Research Council Postdoctoral Fellow at NIST. Since 1982 he has been on the Chemistry faculty at Minnesota, and in 1995 he also became a Professor of Chemical Engineering & Materials Science. In 2013 he was named a Regents Professor, the University’s highest academic rank.
His talk “Ionic Liquid/Block Polymer Nanostructures: Remarkably Versatile, Functional Materials” will be on Thursday, September 5th at 11:30 in LGRT 1634.
Abstract: Ionic liquids are an emerging class of solvents with an appealing set of physical attributes. These include negligible vapor pressure, impressive chemical and thermal stability, tunable solvation properties, high ionic conductivity, and wide electrochemical windows. In particular, the non-volatility renders ionic liquids practical components of devices, but they require structure-directing agents to become functional materials. Block polymers provide a convenient platform for achieving desirable nanostructures by self-assembly, with lengthscales varying from a few nanometers up to several hundred nanometers. Furthermore, ionic liquids and polymer blocks can be selected to impart exquisitely tunable thermosensitivity, by exploiting either upper or lower critical solution transitions (UCSTs and LCSTs). In selected cases, it is also possible to prepare photoreversible and photopatternable systems. Overall, by combining designed block polymers and ionic liquids we have demonstrated materials with superior performance for a remarkably diverse set of applications. These include gate dielectrics in organic transistors, electrochromic and electroluminescent gels, and membranes for gas separation, ion batteries, and fuel cells.
S. ‘Thai’ Thayumanavan, professor of chemistry is awarded the Mahoney Life Sciences Prize for his paper: “Shrink-wrapped Proteins as Next Generation Biologics.” Thayumanavan’s work addresses major challenges in delivering protein-based drugs and devices across a cell membrane while keeping the protein stable and avoiding unwanted immune system responses. The award-winning study presents a “robust and sustainable” strategy which overcomes those challenges: the protein itself serves as a template, and polymers self-assemble to form a sheath around it. The technology has exciting potential applications in therapeutics.
The panel of expert judges praised Thayumanavan’s work as “a major step forward that takes on a long-standing problem,” and “a large advance in the field.” Tricia Serio, dean of the College of Natural Sciences said, “Thai’s approach — to have the protein template its own packaging — is the type of innovative and out-of-the-box thinking that enables transformational advances in science. His work embodies the spirit of this award.”
Richard Vachet, chemistry department head, said, "Thai is a very creative scientist who has a remarkable ability to turn fundamental chemical understanding into new materials that solve real-world problems in biomedicine. His work is a great example of how UMass Amherst researchers are doing translational research."
Through the generosity of the Mahoney family, the prize recognizes UMass Amherst scientists whose work has the potential for advancing connections between research and industry. The Prize includes an award of $10,000 and is awarded annually to one faculty member who has demonstrated excellence in life sciences research, and whose work significantly advances connections between academic research and industry.
Riddha Das, a doctoral student in chemistry, won the 3MT People’s Choice Award. “It was very difficult to condense five or six years of research into three minutes,” she said, “but now if I’m at an interview or a conference, I don’t have to stumble or wonder where to begin.” Das’s research focuses on using nanoparticles to fight cancer.
Organized by the Graduate School’s Office of Professional Development, the annual three-week-long contest tests the research communication skills of 40 doctoral and master’s students by challenging them to explain the significance of their academic projects in accessible and compelling presentations of three minutes or less.
The finalists presented their talks at a public event at Amherst’s Jones Library on March 23.
Gov. Charlie Baker celebrated the opening of the new Physical Sciences Building (PSB) at the University of Massachusetts Amherst, a facility funded by the state that fosters and expands cutting-edge collaborative learning and research at the Commonwealth’s flagship campus.
“We were pleased to invest in the new Physical Sciences Building, which will serve as a hub for the natural sciences at UMass Amherst,” Baker said. “The facility’s expansion will help foster new research and career opportunities, which will help support the STEM workforce pipeline here in Massachusetts.”
Chancellor Kumble Subbaswamy says, “This complex is home to the very best facilities in physics and chemistry, enhancing the research capability for our faculty and students in the College of Natural Sciences and providing the STEM talent that is essential for the state’s innovation economy.

It is with sadness that we report that Emeritus Professor Louis Carpino passed away on January 4, 2019.
Louis started as a faculty member in our Department in 1954 and, while he had been emeritus for a number of years, he remained active in research up until just last year (64 years in total!). Louis was an amazing organic chemist, who is best known for inventing the widely used t-Boc and F-moc amine protecting groups. These developments revolutionized peptide synthesis, with huge downstream impact across a wide swath of science. He was clearly one of the early leaders in putting UMass on the map.
Mingxu You Receives NSF Career Award
Chemistry's Mingxu You Receives NSF Career Award for "A Generalized Quantitative Imaging Approach for Small Molecules using Genetically Engineered RNA Sensors."
Mingxu You's long-term goal is to develop nucleic acid-based next-generation sensor platforms for cell biology studies and disease diagnostics. The overarching goal of his proposal is to engineer an RNA-based general sensing system for the quantitative measurement of metabolites, signaling molecules, and synthetic small molecules in living cells. These RNA-based sensors can be modularly adapted for the measurement of various analytes in individual cells, widely applicable in many clinical, industrial, and ecological settings.
Nature’s Version of Autocorrect
Sankaran “Thai” Thayumanavan, chemistry, has big plans for the $1.8 million National Science Foundation grant the campus has received to create a multi-university Center for Autonomous Chemistry. He and his colleagues, including fellow chemist Vince Rotello, seek to design artificial self-activating systems that mimic how biological systems respond automatically to subtle changes in their environment. Thayumanavan calls the process “automatic control as nature does it.”
He cites as an example the many components of the immune system that remain quiet and dormant until an irritant or pathogen is detected. “Once that happens,” says Thayumanavan, “it’s activated. It’s automatic, organically driven; that’s what we refer to as autonomous. The response requires no other intervention.” Thayumanavan knows of no current artificial systems with that capability and adds, “It would be really valuable if we could develop something like it. We want to figure out the ways in which nature uses molecular interactions to create autonomous function.”
Autonomous chemistry has a broad range of applications. Thayumanavan says that personalized medicine has a high profile at the moment and that the need for this type of innovation is widely and readily understood.
