Pros: good group of colleagues, good support system of faculty and grads
Typical Day: Laboratory work for my thesis (benthic macroinvertebrate identification, organic matter processing, data analysis, thesis writing). Monthly trips to my research sites for field work. Teaching Freshwater Ecology Laboratory (field and lab class).
Learned: Invaluable field and lab skills for stream ecology. How to teach and conduct an upper-level laboratory course. Data analysis and scientific writing (Thesis).
Management and co-workers: Both advisors and fellow grad students fostered a friendly environment in which to work and learn. Senior grad students readily offered their help, knowledge and expertise. Same can be said for advisors
Hardest part of job: balancing my own research for my thesis with the paid portion of my graduate student work - teaching. My advisor gave me more-or-less free reign to conduct the lab class as I saw fit. While this was the hardest part, it also instilled me with a great sense of pride, responsibility, and the ability to multitask.
Most enjoyable part of job: field and laboratory work for my thesis project. I really enjoyed working outdoors in the streams, as well as doing much of my own 'grunt work' in the lab instead of handing it over to undergraduate assistants.
