December

Thesis Defense

Molecular Plasmonics

Thursday, December 8, 2016, 10:00 AM - 11:00 AM
Yao Cui, Doctoral Candidate

Graphene supports surface plasmons that have been observed to be both electrically and geometrically tunable in the midto far-infrared spectral regions. In particular, it has been demonstrated that graphene plasmons can be tuned across a wide spe more  »

Thesis Defense

Development of New Methods for the Synthesis of Novel Biaryls

Monday, December 5, 2016, 9:30 AM - 10:30 AM
Craig Keene, Doctoral Candidate

The abundance of axially-chiral natural products bearing biaryl substructures combined with the number of biaryls used as ligands in chemical transformations makes them an attractive target for establishing new methods for their synthesis. Described more  »

Seminar

“Non-genetic Diversity Modulates Population Performance”

Tuesday, November 29, 2016, 12:30 PM - 1:30 PM
Thierry Emonet, Associate Professor of Molecular Cellular and Developmental Biology & Physics, Yale University

Abstract: Biological functions are typically performed by groups of cells that express predominantly the same genes, yet display a continuum of phenotypes. While it is known how one genotype can generate such non-genetic diversity, it remains unclear more  »

Seminar

“Beyond Cell Shape: Actin Exerts Systems-level Control During Morphogenesis”

Tuesday, November 22, 2016, 12:30 PM - 1:30 PM
Anna Marie Sokac, Assistant Professor, Department of Biochemistry and Molecular Biology, Baylor College of Medicine

Abstract: Changes in cell shape drive embryonic tissue building (i.e. morphogenesis), and actin deficiencies precipitate failed cell shape change and structural birth defects. Yet our understanding of actin’s influence on morphogenesis rarely extends more  »

Seminar

“Bacterial Growth in Fluctuating Environments”

Tuesday, November 15, 2016, 12:30 PM - 1:30 PM
Edo Kussell, Associate Professor, Department of Biology, New York University

Abstract: Bacteria can use memory mechanisms to increase long-term growth rates in rapidly changing environments. In this talk, I will discuss experiments that show the existence of phenotypic memory in E.coli during metabolic transitions. I will pre more  »

Seminar

Edible Molecules to Materials to Devices: White-emitting Protein Fluorescent Nanoparticles for LEDs, Cell-entry and pH Sensing

Wednesday, November 9, 2016, 4:00 PM - 5:00 PM
Challa Vijaya Kumar, Professor of Chemistry, University of Connecticut

Facile synthesis of white-emitting, protein-based, metal-free, stable, non-toxic and pH sensitive, advanced functional nanoparticles (GlowDots) is reported here. Controlled crosslinking of bovine serum albumin (BSA) resulted in efficient formation of more  »

Seminar

“Hydrodynamic Hunters”

Tuesday, November 8, 2016, 12:30 PM - 1:30 PM
Steve Pressé, Assistant Professor, Department of Physics, Indiana University-Purdue University Indianapolis

Abstract: The model bacterial predator, Bdellovibrio bacteriovorus (BV), has been studied for over 50 years and has the potential to purify water, degrade biofilms and serve as a living antibiotic. However, very little is known about BV's hunting str more  »

Seminar

“Beyond the Standard Model of Growth: From Chiral Cells to Polymer Networks”

Tuesday, November 1, 2016, 12:30 PM - 1:30 PM
Kirill Korolev, Assistant Professor, Department of Physics Boston University

Abstract: Growth in living systems is a seemingly well-understood phenomenon. Counter to this belief, I will argue that growth is full of surprises and provide two specific examples: one in polymer networks and one in cellular colonies. First, I will more  »

October

Seminar

Understanding photochemistry and photoelectron spectra with highly correlated ab initio methods of electronic structure theory

Wednesday, October 26, 2016, 4:00 PM - 5:00 PM
Piotr Piecuch, Professor of Chemistry, Michigan State University

Understanding electronic excitation, multi-photon ionization, and photoelectron spectra, particularly those involving strongly correlated dark states, transition metal nano-particles, and larger molecules with transition metal centers, poses a signif more  »

Seminar

“Phenotypic and Genome Evolution of Bacteria”

Tuesday, October 25, 2016, 12:30 PM - 1:30 PM
Dennis Vitkup, Associate Professor, Department of Systems Biology, Department of Biomedical Informatics, Center for Computational Biology and Bioinformatics, Columbia University

Abstract: For many decades comparative analyses of protein sequences and structures have been used to investigate fundamental principles of molecular evolution. In contrast, relatively little is known about the long-term evolution of species' phenoty more  »

Seminar

Novel Nanostructured Materials for Advanced Energy Conversion and Storage

Wednesday, October 19, 2016, 4:00 PM - 5:00 PM
Ying Wang, Associate Professor, Louisiana State University

The exploration of new, safe, and inexpensive rechargeable batteries with high energy-density electrodes is a key to integrate the renewable sources such as solar and wind, and address the sustainability issues. A variety of facile and cost-effective more  »

Seminar

“Lattice Boltzmann Simulation of Complex States of Flowing Matter”

Tuesday, October 18, 2016, 12:30 PM - 1:30 PM
Sauro Succi, Research Affiliate, Physics Department, Harvard University

Abstract: Over the last near three decades, the Lattice Boltzmann (LB) method has gained a prominent role as an efficient computational scheme for the numerical simulation of complex flows across a broad range of scales, from fully developed turbulen more  »

Seminar

Enabling Synthesis and Medicinal Chemistry with Continuous Flow Reactions

Wednesday, October 12, 2016, 4:00 PM - 5:00 PM
Aaron Beeler, Assistant Professor, Boston University

Development of reactions in flow has many advantages, but perhaps the most enabling is the ability to facilitate transformations that are challenging or even impossible by traditional batch methods. In my group, we are working to develop these reacti more  »
