Colloquium

Rethinking algorithms in Data Science: Scaling up optimization using non-convexity, provably

Thursday, February 23, 2017, 4:00 PM - 5:00 PM
Dr. Anastasios Kyrillidis, Simons Fellowship Postdoctoral Researcher at the University of Texas, Austin

With the quantity of generated data ever-increasing in most research areas, conventional data analytics run into solid computational, storage, and communication bottlenecks. These obstacles force practitioners to often use algorithmic heuristics, in more  »

Seminar

Gold Nanostar Stability and Use in Complex Matrices

Wednesday, February 22, 2017, 4:00 PM - 5:00 PM
Amanda J. Haes, Associate Professor of Chemistry, University of Iowa

With the growing inclusion and use of nanoparticles in products and devices, developing characterization tools and experimental methods that can be used to predict nanoparticle fate are increasingly important. Two challenges and approaches to better more  »

Seminar

"Phase Transitions and the Principle of Detailed Balance in Living Systems"

Tuesday, February 21, 2017, 12:30 PM - 1:30 PM
Fred MacKintosh, Abercrombie Professor, Chemical & Biomolecular Engineering, Professor of Physics & Astronomy

Abstract: The mechanics of cells and tissues are largely governed by scaffolds of filamentous proteins that make up the cytoskeleton, as well as extracellular matrices. Evidence is emerging that such networks can exhibit rich mechanical phase behavio more  »

Seminar

Taking charge of proteins (and pediatric ophthalmology)

Wednesday, February 15, 2017, 4:00 PM - 5:00 PM
Bryan F. Shaw, Associate Professor of Chemistry and Biochemistry, Baylor University

The first part of this seminar will present an overview of our work in protein electrostatics. We are examining whether the net electrostatic charge of a protein represents a druggable parameter in diseases linked to protein self-assembly. For exampl more  »

Seminar

Dow Lecture: 2-Dimensional Zeolites

Tuesday, February 14, 2017, 2:30 PM - 3:30 PM
Michael Tsapatsis, Professor of Chemical Engineering and Materials Science, University of Minnesota

It is only recently that single-unit-cell thick zeolite nanosheets (2-dimensional zeolites; AIChE Journal 60(7), 2374-2381 (2014) ) with intact crystal and micropore structure were shown to be possible. The structural integrity and uniformity of thes more  »

Seminar

'Signaling in Cell Shape and Motility: from Single Cells to the Collective Behavior of Multiple Cells”

Tuesday, February 14, 2017, 12:30 PM - 1:30 PM
Leah Edelstein-Keshet, Professor, Department of Mathematics, University of British Columbia

Abstract: In this talk I will describe recent work on the signaling inside cells that controls the cytoskeleton, and thereby the shape and motility of a eukaryotic cell. I will focus on our recent analysis of regulatory proteins (the small GTPases Ra more  »

Seminar

“Cellular Variability and Information Flow in Signal Transduction Networks”

Tuesday, February 7, 2017, 12:30 PM - 1:30 PM
Roy Wollman, Associate Professor, University of California, Los Angeles

Abstract: Signaling networks acts as sensors, or measurement devices, that provides information on the extracellular environment to allow cells to respond to environmental changes appropriately. Experimental single cell measurements of signaling res more  »

Lecture/Lecture Series

Franklin Lecture: Self-assembled Plasmonic Structures

Wednesday, February 1, 2017, 4:00 PM - 5:00 PM
George C. Schatz, Professor of Chemistry, Northwestern University

Recently there has been growing interest in the coupling of self-assembly chemistry with the formation of silver and gold nanoparticles, to create a new generation of materials of interest for sensing and optical devices. This talk describes the self more  »

Seminar

“DNA Programmed Dynamical Systems Outside Cells: from Gene Circuits to Self-Assembly”

Tuesday, January 31, 2017, 12:30 PM - 1:30 PM
Vincent Noireaux, Associate Professor, School of Physics and Astronomy, University of Minnesota

Abstract: The analysis and characterization of complex dynamical interactions involved in gene regulation is a major theme in post-genomic research. Researchers from many different backgrounds have developed novel approaches to dissect gene network a more  »

Seminar

“Hidden Interactions in Resource-limited Genetic Circuits”

Tuesday, January 24, 2017, 12:30 PM - 1:30 PM
Domitilla Del Vecchio, Associate Professor, Massachusetts Institute of Technology

Abstract: Synthetic genetic circuits are “powered” by cellular resources, which are found in limited amounts. The sharing of these resources by different circuit components often hampers the functionality of circuits. In this talk, I will illustrate more  »

Seminar

Measuring Long-range Correlated Dynamics in Organic Glasses

Wednesday, January 18, 2017, 4:00 PM - 5:00 PM
Zahra Fakhraai, Assistant Professor of Chemistry, University of Pennsylvania

Nanometer-sized thin films of small organic molecules are widely used in applications ranging from organic photovoltaics and organic light emitting diodes, to protective coatings and high resolution nano-imprint lithography. Physical vapor deposition more  »

Seminar

"Systems Biology in Single Cells: A Tale of Two Viruses

Tuesday, January 17, 2017, 12:30 PM - 1:30 PM
Abhyudai Singh, Assistant Profesor, University of Delaware

Abstract: In the noisy cellular environment, expression of genes has been shown to be stochastic across organisms ranging from prokaryotic to human cells. Stochastic expression manifests as cell-to-cell variability in the levels of RNAs/proteins, in more  »

Seminar

Synthetic Nucleic Acid Topology and Colloidal LEGO-Like Nanoparticles for Biological and Plasmonic Applications

Wednesday, January 11, 2017, 4:00 PM - 5:00 PM
Yossi Weizmann, Assistant Professor of Chemistry, University of Chicago

The iconic double helical structure of DNA has excited the imagination of both scientists and non-scientists for more than six decades. In recent times, the programmable nature of DNA has redefined its use as a powerful building material for the cons more  »
