Summer Research Program back to (nearly) normal in 2021

SciFest 2019With increasing vaccination rates and declining positive Covid test rates, the Division of Science is looking forward to a vibrant, in-person summer undergraduate research program kicking off right after Memorial Day. 

The Division of Science summer program pairs first-hand research, community building, and guidance from Brandeis graduate students and postdoctoral fellows to provide undergraduate students a high-quality research experience. Past summer undergraduates have gone on to make substantial contributions (even as first authors!) to peer-reviewed research publications in fields such as materials chemistry (Shi et al., “Sunlight-activated phase change materials for controlled heat storage and triggered release”), molecular biology (Lamper et al., “A phosphorylation-regulated eIF3d translation switch mediates cellular adaptation to metabolic stress”) and neuroscience (He et al., “Rapid adaptation to Elevated Extracellular Potassium in the Pyloric Circuit of the Crab, Cancer borealis).

For Summer 2021, we are excited to announce that 58 Brandeis undergraduate researchers will be supported through the Division of Science programs and funding sources including NSF, NIH, and generous Brandeis alumni and foundation donors.

Additionally, the MRSEC Research Experience for Undergraduates (REU) program will support 6 undergraduate students from Hampton University for a 10-week, hands-on research program that runs in parallel with the MRSEC Summer Materials Undergraduate Research Fellowship. REU participants are mentored by MRSEC graduate students and postdoctoral fellows and contribute to materials science research efforts on Brandeis’s campus.

We will conclude the summer with SciFest, our annual summer poster session showcasing undergraduate research in the sciences, on August 5. Check the SciFest website for updates about the time and details for the session. 

Congratulations to all fellowship recipients! 

Learning from how viruses assemble

Michael Hagan, Professor of Physics, is quoted extensively in the Chemical & Engineering News article, Lessons learned from watching viruses assemble. The paper discusses how scientists are studying the ability for viruses to self-assemble. During a viral infection, infected cells manufacture the genetic material and other components of the virus. These components then self-assemble, or build themselves into complex shapes, to form new viruses capable of infecting additional cells.

Many viruses contain their genetic material within a protective shell known as a capsid. Michael Hagan is one of the scientists studying how these capsids are formed by modeling the conditions and chemical properties that allow viruses to build themselves. Once understood, researchers hope this will help in drug design and delivery.

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.

Lisa Piccirillo, a recent Brandeis postdoc and Netta Engelhardt, a Brandeis undergraduate alumni have received two awards from the Breakthrough Prize Foundation. While the Breakthrough Prizes are intended to help scientific leaders gain financial freedom, the New Horizons award and the Maryam Mirzakhani New Frontiers Prize focus on young scientists early in their careers.

The Maryam Mirzakhani New Frontiers Prize is awarded to early-career women mathematicians. Lisa Piccirillo received this prize for her work in resolving the Conway Knot problem. Piccirillo was a postdoc working with Daniel Ruberman, Professor of Mathematics, from 2019 until her recent appointment as Assistant Professor at Massachusetts Institute of Technology.

Netta Engelhardt, is part of a group that received the 2021 New Horizons in Physics Prize. Netta and three other scientists were awarded for their research in calculating the quantum information content of a black hole and its radiation. Engelhardt is currently an Assistant Professor of Physics at Massachusetts Institute of Technology. She was a 2011 graduate who majored in Physics. She received a NSF Graduate Research Fellowship prior to graduating from Brandeis.

 

Meet the Science UDRs at the Ultimate Science Navigation Event (9/23)

Ultimate Science Navigation posterAt The Ultimate Science Navigation event TOMORROW (9/23), students can collaborate with the science UDRs to learn about the different offerings in the sciences, how to navigate each major/minor, what each major/minor has to offer, all with an emphasis on exploring the intersections between different programs in the sciences. We will have UDRs representing biochemistry, biology, neuroscience, chemistry, physics, and biophysics!

Students can join in the morning on Zoom from 9:30-10AM, or for the rest of the day through the new Brandeis science community Slack workspace to discuss their questions related to the majors with the UDRs! Email Lance Babcock (lbabcock@brandeis.edu), Maggie Wang (maki@brandeis.edu) or the other science UDRs for the Zoom link and Slack workspace link.

DNA molecules tell nanoparticles how to self-assemble

Nature uses self-assembly to make a diversity of complex structures, such as biomolecules, virus shells, and cytoskeletal filaments. Today a key challenge is to translate this assembly process to artificial systems. DNA-coated nanoparticles provide a particularly promising approach to realizing this vision, since the base sequences can be designed to encode the formation of a chosen structure.

A recent publication from the Rogers Lab shows that interactions between DNA-coated particles can be encoded using DNA oligomers dispersed in solution that bind the particles together.  By changing the linker sequences in solution, Ph.D. students Janna Lowensohn and Alex Hensley showed that the same set of components can be directed to form a variety of different crystal structures. Going forward, this approach may be used to create programmable materials that can sense and respond to their environment.
