Remote Access

Ames Laboratory Information Systems supports three means for remotely accessing internal computers and network services. These are:

  1. Virtual Private Network (VPN)
  2. Secure SHell (SSH)
  3. Dial-up Modems

Once connected remotely to Ames Laboratory, Information Systems supports several means to connect with office and lab computers. These are explained in more detail in our FAQ: How do I get remote access to my office/lab computer.

Research Interests

Far-field optical imaging methods are essential for precise visualization of the dynamics of biomolecules and nanoparticles because they require no contact and make minimal intrusion to the sample. The research in the Fang Laboratory is aimed to open up new frontiers in chemical and biological discovery through the development and use of a novel optical imaging platform, which provides sub-diffraction-limited spatial resolution, high angular resolution, excellent detectability, and nanometer localization precision for single molecules and nanoparticles in live biological samples and microfluidic devices.
