Gieseking Receives NSF CAREER Award

Figure from Rebecca GiesekingRebecca Gieseking, Assistant Professor of Chemistry, has received an NSF CAREER award from the Chemical Theory, Models and Computational Methods program. This award will enable her research group to develop computational models that provide chemical understanding of how light interacts with metal nanoclusters.

Harnessing solar energy is crucial to reduce humanity’s dependence on fossil fuels and alleviate the environmental impact of our ever-increasing demand for energy. Noble metal nanoclusters containing tens to hundreds of metal atoms have the potential to revolutionize solar energy technologies by harnessing light to produce chemical fuels. These nanoclusters strongly absorb light because they support plasmons, which are collective oscillations of the electrons. Understanding, controlling, and manipulating the plasmon properties is key to improving the efficiency of solar energy storage.

Rebecca has shown that efficient computational models can accurately model the light absorption of metal nanocluster, and her group is now extending these models to understand the decay processes after metal nanoclusters absorb light. They are using these models to understand how these decay processes change as a function of nanocluster size, shape, and composition to design metal nanoclusters with controllable decay time scales for efficient solar energy storage.

Bulbul Chakraborty Elected AAAS Fellow

Bulbul ChakrabortyBulbul Chakraborty, the Enid and Nate Ancell Professor of Physics and head of the Division of Science, has been named a Fellow by the American Association for the Advancement of Science. This honor is in recognition of Professor Chakraborty’s important theoretical contributions in the area of condensed matter physics, particularly disordered systems including frustrated magnets and granular materials.

Chakraborty has been a Brandeis faculty member since 1989. She is a condensed matter theorist who is currently focused on understanding the emergence of rigidity in solids that emerge in strongly nonequilibrium processes such as jamming or gelation.

A virtual induction ceremony for the newly elected Fellows will be held in February 2021.

Hedstrom Receives NIH Director’s Transformative Research Award

Liz HedstromBrandeis University chemical biologist Lizbeth Hedstrom received one of nine Director’s Transformative Research Awards this year from the National Institutes of Health under its High-Risk, High-Reward Research Program.  The 5-year, $3.5 mil grant will support the development of new methods for drug design relying on targeted protein degradation.  This emerging strategy has several potential therapeutic advantages over traditional approaches, including the development of more potent, longer acting, drugs.

The rational design of ‘degraders’ has focused almost exclusively on degradation induced when the target protein is modified with ubiquitin.  In contrast, Hedstrom will be developing ubiquitin-independent strategies.

The Rogers Lab receives a prestigious international grant to study the origin of life

HFSP logoProfessor W. Benjamin Rogers in the Department of Physics has been awarded a 2020 Human Frontier Science Program (HFSP) collaborative Program Grant to create a self-propagating synthetic cell. The HFSP Program Grants aim to tackle big questions in the life sciences by supporting and bringing together researchers with different backgrounds from different countries. Professor Rogers’ team grant was one of 20 successful Program Grants that went through a year-long global selection process.

The project aims to build a stably-propagating cell from simple components. The cell will have a lipid membrane encapsulating DNA and transcription-translation machinery, and be able to grow and divide by internally synthesizing its own membrane material.

The project is significant because a stably propagating cell is a vital element of natural selection. Extant life on Earth is a consequence of natural selection acting upon earlier forms of life, shaping the lineages over time. Thus at some point early in life’s origins, a sustainably propagating cell must have emerged, allowing selective advantages to accumulate over successive generations. For daughter cells to have retained the attributes of their parent, both the genetic information and the cell contents must have been replicated with reasonable fidelity.  However, it is currently unclear how controlled cell division could have first emerged from relatively simple molecules. It is precisely this mystery that the team hopes to understand by attempting to recreate it in a test tube.

Professor Rogers’ grant is shared with Dr. Yutetsu Kuruma from Japan Agency for Marine-Earth Science and Technology and Professor Anna Wang from University of New South Wales in Australia.

Eve Marder and Liqun Luo receive 2019 NAS awards

Eve Marder NAS award

Eve Marder, the Victor and Gwendolyn Beinfield Professor of Neuroscience, has received the 2019 National Academy of Sciences Award in the Neurosciences. The National Academy of Sciences is recognizing “Marder’s research of over more than 40 years that has provided transformative insight into the fundamental processes of animal and human brains.” NAS also called Marder “one of the most influential neuroscientists of her generation”.

Liqun Luo

In addition to her research, NAS acknowledged Marder’s impact upon young scientists working in her field. She has served as a mentor to “generations of neuroscientists”.  A book titled “Lessons from the Lobster: Eve Marder’s Work in Neuroscience” by Charlotte Nassim and was published in 2018.

The NAS Award in the Neurosciences is given only once every three years.

In addition to Marder, a Ph.D. alumnus is among the 18 scientists that are being recognized this year. Liqun Luo received the Pradel Research Award.  In the press release, NAS cited Luo’s “pioneering research into neural circuits of invertebrates and vertebrates.”

Luo earned his Ph.D. in Biology from Brandeis in 1992. He worked in Kalpana White’s lab. He is now a Professor and HHMI Investigator at Stanford University.

Jeff Gelles to Receive 2019 BPS Kazuhito Kinosita Award in Single-Molecule Biophysics

Congratulations to Jeff Gelles, Aron and Imre Tauber Professor of Biochemistry and Molecular Pharmacology. He will receive the 2019 Kazuhito Kinosita Award in Single-Molecule Biophysics from the Biophysical Society (BPS). He will be honored at the Society’s 63rd Annual Meeting at the Baltimore Convention Center on March 5, 2019, during the annual Awards Symposium.

The award, named for Professor Kazuhiko Kinosita, seeks to advance cross-disciplinary research and cultivate an appreciation of single-molecule studies. BPS President Angela Gronenborn, University of Pittsburgh, said “Jeff has conducted single-molecule studies at the highest level and continues to spark interests in engaging others in single-molecule studies.” (BPS Press Release)
