Elucidating Principles of Biological Signal Processing Using Microfluidic and Optogenetic Tools

Biological networks, like electrical circuits, take specific inputs (nutrient availability, stress, hormones) and convert them into appropriate outputs (transcriptional responses, metabolic remodeling). Electrical engineers uncover the inner workings of such circuits by measuring the transfer function between input voltage and output voltage. However, unlike electrical engineers, biologists are more limited in the input signals they can generate to interrogate such networks. We are developing microfluidic and optogenetic tools to generate dynamic inputs to interrogate and control natural and synthetic biological networks. In this talk I will discuss our use of microfluidics to dissect the mechanisms and kinetics of signaling in stress response networks in the budding yeast Saccharomyces cerevisiae. In addition, I will discuss our recent efforts to develop real-time optogenetic control of protein concentration as a tool for manipulating biological networks.

The Search For New Physics in the LHC Age

The first run of the LHC has just completed and the first set of analyses have just come out. I will review the state of searches for new physics at the LHC and give interpretations of the results. I will focus on the interplay between the discovery of the Higgs boson and the implications for supersymmetric extensions of the Standard Model.

Effective Field Theory and the Emergence of New Dynamics
image for colloquium abstract
I describe applications of Effective Field Theory (EFT) to a broad range of scenarios where novel physics has been observed but the details remain poorly constrained. I discuss how EFT allows one to simplify and organize existing models, as well as providing an efficient framework for envisioning and parameterizing general possibilities in a more model-independent manner. Applications covered will be inflation in the early universe, experiments looking for direct detection of dark matter, and novel phases in superconducting metals.
