Microbial Community Compositions & Obesity
Humans
Are we there yet?
• Therapeutic targets - altering gut microbiomes of obese
individuals
• Conflicting reports about relationships between gut
microbiota taxonomy compositions and obesity
• Large surveys of data from multiple studies have led to
inconsistent results
• Inter-study variability in fecal microbiome communities
exceeds differences between lean and obese individuals
Crosstalk Between Experimental & Computational Scientists
• Dr. Peter Turnbaugh, Microbiologist (Harvard University)
Gut microbial promotion of energy gain on processed diets
• Dr. Elhanan Borenstein, Computational Biologist (University of Washington)
Studying the human microbiome: From metagenomics systems
biology to multi-meta-omic analysis
• Dr. Katie Pollard, Statistician (University of California at San Francisco)
Variability and potential causes for inconsistencies in human data sets
