Project Plan and Execution
Initial Plan
• May – June – Brainstorm and finalize design
• July – August
– Obtain constructs and test
• September – October– Make revisions, fine tune model parameters, obtain
and test new constructs
Actual Execution
• May – August– Brainstorm designs
• September– Found out we needed to prepare constructs ourselves– Reconfigure designs to use available parts– Recruitment of volunteers with wet lab experience
• October – Early Nov.– Undergraduates began assembly– Coincided with peak of undergrad midterm season
Initial Assembly Schedule Part Week 1 Week 2 Week 3 Week 4

Lessons for Next Year
• Larger team• Schedule undergraduate lab time more
effectively• Prepare team for assembly
