November 2008 - The Ralph Lab teamed up with the Mehl Lab and held an official lab opening party. Presentations were given by Dr. Ralph and Dr. Mehl, along with the graduate students from each lab. A cake reception took place afterwards, and then the Ralph Lab continued the fun by heading out to dinner at a local restaurant. The opening party was to thank everyone in the biology department at UND for their support and help in setting up the new labs.
