Connecting Two Labs

Dr. Steve DeWeerth is a member of the Laboratory for Neuroengineering. He has been collaborating with Emory researchers through a joint program. DeWeerth and Dr. Richard Nichols at Emory currently have graduate students that are doing research at Georgia Tech and Emory in multidisciplinary fields combining biology and electrical engineering disciplines.

These students are trying to understand how locomotion works by looking at spinal cords of rats and examining how their locomotion circuitry works. They do this by examining a rat's spinal cord and they also build electrical devices to simulate spinal cords (see photo). The experiments require wet lab time at Emory followed by electrical data analysis time at Georgia Tech. As the student collects more data and moves into the latter stages of their PhD, they spend more time at Georgia Tech but need to train newer students at Emory. Coordinating this can be challenging.

There are two training issues that are critical. One issue is scheduling a training session where two students agree that they will do an experiment together and one will guide the other through the process. The second issue is being able to quickly interrupt someone with a question that needs an immediate response.

A demo is being put together to try and address both issues. Georgia Tech and Emory are connecting a dedicated point to point 1Gigabit Ethernet connection from the Nichols lab in the Whitehead buidling to the DeWeerth lab in the Whitaker building. A compressionless video application will be used over this high bandwidth connection to help a student at Tech remotely train a student at Emory. The hope is that the two students will not have travel time and this can facilitate more frequent training sessions. We also hope that a 24 hour accessible video connection that is has low jitter and latency will be appealing and lend itself to natural conversational collaboration. It was made clear that sometimes the student only needs a quick question answered to finish an experiment. Supporting a way to interrupt an expert briefly and then move on is highly desired.

Once the demo is performed, we would like to not only assess whether the two issues outlined are handled or improved in any way but also how this untraditional network solution performed. Is this the right way to handle these obstacles? Will it becomes transparent to the researchers so that they can focus on their research rather than deal with the technology beneath? We will continue to ask these questions as we observe.

Because there are many pieces to this demo, it will be important to look at all of them to see what is successful and what might need improving. There is a network, a cutting edge application, and a change in process in the lab. Is it one of the things, all, or none that make a difference to the research progress? As we learn how to answer that question, with the help of the researchers, we will design a combination that best benefits them.

Currently, equipment is ordered and we await installation. A progress report will posted when available.
