Research

Research Principles at the laboratory

1. Work when you work, relax when you relax. – Focus is most important

2. Take ownership in what you do.

3. Spend 50 hours/week minimum at office. – Now is the time to learn the fundamentals.

4. Value the learning process. – Rome was not built in a day.

5. Be ambitious and enjoy student life.
