Approaches to Taxonomy in the Microbiome 
April 13th, 2017

This introductory lecture, led by Kyle Bittinger PhD, covered the process of turning DNA sequence data into information about bacterial communities.  Some approaches are purely numerical, while others involve associating the sequences with genus or family names.  Methods of creating “operational taxonomic units” and the dangers of making taxonomic assignments were also be discussed.

Ecological Diversity in the Microbiome
April 27th, 2017

In the second lecture of our spring series, Kyle Bittinger PhD discussed the diversity of bacterial communities.  Diversity can mean the number of species observed in each sample (alpha diversity) or the number of species shared between samples (beta diversity).  The way diversity is used to analyze bacterial communities was discussed, as well as special topics such as UniFrac distance and principal coordinates analysis.

Weekly ‘Code Review’
9:00 AM  EST
Every Wednesday
207 Johnson Pavilion

Kyle Bittinger, a Computational Biologist from Dr. Rick Bushman’s lab, leads this weekly session.  Each week one person presents programming code related to their research.  Attendees get a chance to hear how code was assembled to achieve a goal, while the presenter gets feedback, collective troubleshooting, etc. Less experienced programmers will have a chance to learn about design options when programming.

R Learning Group
1:00 PM EST
very Wednesday
WIC Seminar Room, Van Pelt Library

R is an open-source coding language used by a wide range of disciplines for data management, statistical analyses, and data visualization. Beginning January 4, 2017, an informal R learning group for members of the Penn community meets on Wednesdays from 1pm until 2pm starting in the WIC Seminar Room (Van Pelt 124.)  So far, we’ve been working with swirl, a software package designed for learning R commands and introductory data science. No experience is required. This is self-paced learning, so feel free to come every week or drop in as you are able.  Please click here for more information.
