IEG Data Analysis Workshop 2019-2020 is coming

Microbiome Data Analysis Workshops by Institute for Environmental Genomics @ OU

Time: Friday 10:00 to 12:00 am on Dec 13 and from Jan 10 to Mar 20.

Location: SRTC board room (room 1020), 101 David L Boren Blvd, Norman. * On Dec 13, we will use the SRTC core room.

Topics: The workshops are mainly about microbial community data analysis. Each workshop has introduction and hands-on practice (you need to bring your own laptop). Current schedule is as below. Further changes will be announced via email list and on Please contact daliang ( to be included in the email list if you are interested.
