Career Center’s “30 Minutes” Research Week

Interested in learning more about careers related to research?  Sign up to meet with Joe Eskola '89, Mike Kesti '88, or Janice Huwe '79 during fifth week for "30 Minutes" Research Week (5th Week).  Joe Eskola '89 will be on campus Monday, April 23, between 1:00-5:00 PM, Mike Kesti '88 will be on campus Tuesday, April 24, between 1:00-5:00 PM, and Janice Huwe '79 will be on campus Friday, April 27, between 1:00-5:00 PM meeting with students interested in their field of work.  The “30 Minutes” program brings students interested in a specific job or field face-to face with alumni experienced in that field for casual and candid thirty minute informational interviews in the Career Center.  It is the perfect opportunity for students to network with alumni, learn about specific career paths, and gain industry-related advice.  The bios of the alumni are attached.

If you are interested in meeting with Joe Eskola, Mike Kesti, or Janice Huwe, sign up here:  https://docs.google.com/spreadsheet/ccc?key=0AvsGiTZk_UvhdFlxMmNyaFpwZ2U5TFNtMlZpbDVpLUE#gid=0.  Feel free to email (southgab@carleton.edu) with any questions you may have.

Under the hood:  Single-molecule studies of DNA replication

Novel nanomanipulation and imaging methods have made it possible to study biochemical reactions at the level of individual proteins.  In a biological context, most of these proteins function in concert with others in multi-protein complexes, so an important future direction is the utilization of single-molecule techniques to unravel the orchestration of large macromolecular assemblies.  I will discuss our single-molecule studies of the replisome, the multi-protein machinery that is responsible for replication of DNA.  I will present experiments that rely on the readout of mechanical DNA properties as well as single-molecule fluorescence imaging to obtain information on the catalytic activity and dynamic composition of the bacterial replisome.  Further, I will discuss new results on the study of individual eukaryotic replisomes in Xenopus cellular extracts.


Journal Club Meets This Week

Surface Bioengineering of Gold Nanorods

The promise of nanotechnology encompasses the energy, health care, defense, and chemical manufacturing sectors of the global economy.  Gold nanorods are a class of nanomaterials that have tunable optical properties depending on particle shape, and these optical properties are key to sensor and imaging technology that directly impact these sectors of the global economy.  In this talk I will detail how these nanomaterials are made and characterized, how the surface chemistry can be tuned to manipulate nanomaterial properties, and how the nature of the nanomaterial surface influences biological response at the molecular, cellular, and ecosystem levels.
