Alshakim Nelson receives NSF CAREER Award

Assistant Professor Alshakim Nelson has received a CAREER Award from the National Science Foundation. The CAREER (Faculty Early Career Development) Program is a Foundation-wide program that “offers the National Science Foundation’s most prestigious awards in support of junior faculty who exemplify the role of teacher-scholars through outstanding research, excellent education and the integration of education and research within the context of the mission of their organizations.”

Professor Nelson applies his expertise in organic chemistry, polymer chemistry, and supramolecular chemistry to design stimuli-responsive materials for life science applications. Using interdisciplinary approaches such as living anionic polymerizations, rheological characterization, culturing microbes, and direct-write 3D printing, the Nelson research group is leveraging the stimuli-responsive behavior of materials to facilitate their fabrication or patterning. Ongoing work includes the development of polymer-living cell composite materials (“living materials”) and polymers to create anatomical models for human tissue.

Professor Nelson’s NSF CAREER proposal, “CAREER: Supramolecular engineering of hydrogel forming triblock copolymers,” aims to elucidate molecular-level design principles that can govern and control the physical properties of hydrogels. Improved understanding of the properties of hydrogels—soft materials largely comprised of water with numerous health-related uses (e.g., hygiene, contact lenses, medical implants, wound care)—will foster new design strategies for this important class of materials. In addition to the scientific goals, this project aims to expand access to and interest in polymer science for pre-college and college students and increase diversity within the field. Efforts will include the creation of educational modules to introduce polymer science to K-12, undergraduate, and graduate students, the engagement of disadvantaged and under-represented groups in STEM, and an emphasis on teacher training to maximize the overall impact of this project.

Chiu, Vaughan receive NIH Transformative Research Award

Assistant Professor Joshua Vaughan and Professor Daniel Chiu are among the eight awardees selected by the National Institutes of Health (NIH) for a 2017 NIH Director’s Transformative Research Award. This program is one of four in the NIH High-Risk, High-Reward Research program, which funded 86 awards to scientists working in biomedical research in 2017.

The NIH High-Risk, High-Reward Research program funds exceptionally creative scientists proposing to use highly innovative approaches to tackle major challenges in biomedical research. The program accelerates scientific discovery by supporting high-risk ideas with high-impact potential, and applicants are encouraged to think outside the box and to pursue exciting, trailblazing ideas in any area of research relevant to the NIH mission.

The NIH Director’s Transformative Research Award, established in 2009, promotes cross-cutting, interdisciplinary approaches and is open to individuals and teams of investigators who propose research that could potentially create or challenge existing paradigms.

Professors Chiu and Vaughan are developing radical new technologies for high-resolution mapping of brain tissue, including circuit-level spatial information down to a resolution of 50 nanometers and comprehensive analysis of the types of proteins present across large regions of the brain. These techniques are needed because it is technically difficult to directly detect large numbers of proteins in brain tissue.

Instead of trying to measure proteins directly, most approaches measure RNA molecules—a precursor to proteins. But RNA detection in spatially complex brain tissue has its flaws. Current approaches struggle with dim signals that are difficult to detect over background noise in complex, thick tissues. Professors Chiu and Vaughan will develop new fluorescent probes to light up RNA molecules in tissues and will use a novel, large-area light sheet microscope—together with sample processing techniques—to rapidly probe large volumes of brain tissue at high spatial resolution.

The work of 2017 NIH award recipients will be featured at the 2018 High-Risk, High-Reward Research Symposium, held June 6-8, 2018 in Bethesda, MD. The symposium is free, open to the public, and will bring together recipients of the NIH Director’s Pioneer, New Innovator, Transformative Research, and Early Independence awards to share their groundbreaking research and discoveries.

UW and PNNL launch NW IMPACT in joint pursuit of new materials

UW News story by James Urton

Many innovations of 21st century life, from touch screens and electric cars to fiber-optics and implantable devices, grew out of research on new materials. This impact of materials science on today’s world has prompted two of the leading research institutions in the Pacific Northwest to join forces to research and develop new materials that will significantly influence tomorrow’s world.

With this eye toward the future, the Department of Energy’s Pacific Northwest National Laboratory and the University of Washington announced the creation of the Northwest Institute for Materials Physics, Chemistry and Technology — or NW IMPACT — a joint research endeavor to power discoveries and advancements in materials that transform energy, telecommunications, medicine, information technology and other fields. UW President Ana Mari Cauce and PNNL Director Steven Ashby formally launched NW IMPACT during a ceremony on January 31 at the PNNL campus in Richland, WA.

PNNL and UW leaders attend the launch of NW IMPACT at the PNNL campus on Jan. 31. Left-to-right: NW IMPACT co-director David Ginger; UW President Ana Mari Cauce; PNNL Director Steven Ashby; NW IMPACT co-director Jim De Yoreo.

“This partnership holds enormous potential for innovations in materials science that could lead to major changes in our lives and the world,” said Cauce. “We are excited to strengthen the ties between our two organizations, which bring complementary strengths and a shared passion for ground-breaking discovery.”

“The science of making new materials is vital to a wide range of advancements, many of which we have yet to imagine,” said Ashby. “By combining ideas, talent and resources, I have no doubt our two organizations will find new ways to improve lives and provide our next generation of materials scientists with valuable research opportunities.”

The institute builds on a history of successful partnerships between the UW and PNNL, including joint faculty appointments and past collaborations such as the Materials Synthesis and Simulations Across Scales Initiative, the PNNL-led Battery 500 consortium, and the UW Molecular Engineering Materials Center, a new NSF-funded Materials Research Science and Engineering (MRSEC) Center. But NW IMPACT is the beginning of a long-term partnership, forging deeper ties between the UW and PNNL.

The goal is to leverage these respective strengths to enable discoveries, innovations and educational opportunities that would not have been possible by either institution alone.

“By partnering the UW and PNNL together through NW IMPACT, the sum will truly be greater than the parts,” said David Ginger, a UW professor of chemistry and chief scientist at the UW Clean Energy Institute. “We are joining together our expertise and experiences to create the next generation of leaders who will create the materials of the future.”

Ginger will co-lead the institution in its initial phase with Jim De Yoreo, chief scientist for materials synthesis and simulation across scales at PNNL and a joint appointee at the UW.

Over its first few years, NW IMPACT aims to hire a permanent institute director, who will be based at both PNNL and the UW; create at least 20 new joint UW-PNNL appointments among existing researchers; streamline access to research facilities at the UW’s Seattle campus and PNNL’s Richland campus for institute projects; involve at least 20 new UW graduate students in PNNL-UW collaborations; and provide seed grants to institute-affiliated researchers to tackle new scientific frontiers in a collaborative fashion.

Some of the areas in which NW IMPACT will initially focus include:

  • Materials for energy conversion and storage, which can be applied to more efficient solar cells, batteries and industrial applications. These include innovative approaches to create flexible, ultrathin solar cells for buildings or fabrics, long-lasting batteries for implantable medical devices, catalysts to enable high efficiency energy conversion and industrial processes, and manufacturing methods to synthesize these materials efficiently for commercial applications.
  • Quantum materials, such as ultrathin semiconductors or other materials that can harness the rules of quantum mechanics at subatomic-level precision for applications in quantum computing, telecommunications and beyond.
  • Materials for water separation and utilization, which include processes to make water purification and ocean desalination methods faster, cheaper and more energy-efficient.
  • Biomimetic materials, which are synthetic materials inspired by the structures and design principles of biological molecules and materials within our cells — including proteins and DNA. These materials could be applicable in medical settings for implantable devices or tissue engineering, and for self-assembled protein-like scaffolds in industrial settings.

“The science of making materials involves understanding where the atoms must be placed in order to obtain the properties needed for specific applications, and then understanding how to get the atoms where they need to be,” said De Yoreo.

NW IMPACT will draw on the unique strengths and talents of each institution for innovative collaborations in these areas. For example, PNNL has broad expertise in materials for improved batteries. The lab also offers best-in-class imaging, NMR and mass spectrometry capabilities at EMSL, the Environmental Molecular Sciences Laboratory, a DOE Office of Science user facility. DOE supports fundamental research at PNNL in chemistry, physics and materials sciences that are key to materials development. The UW brings complementary facilities and equipment to the partnership, such as the Washington Clean Energy Testbeds and a cryo-electron microscopy facility, as well as expertise in a variety of “big data” research and training endeavors, highly rated research and education programs, and ongoing materials research projects through the National Science Foundation-funded Molecular Engineering Materials Center.
