Although the extent of their responsibilities depends on their place or employment industry, it usually includes adhering to guidelines and timelines, narrowing down leads to gather and analyze data, consulting with experts, and maintaining records of all procedures. As a Senior Research Investigator, it is essential to lead and serve as a role model to less experienced investigators in the joint effort to reach project goals, all while implementing the facility's standards and regulations.
A doctoral fellow is a physician that has completed studies and receives a fellowship to cover his/her or her expenses while completing his/her or her medical dissertation. A doctor fellow undergoes this fellowship to get additional training for their chosen sub-specialty. During the fellowship period, a fellow can act as an attending physician or consultant physician with other physicians' direct supervision in the sub-specialty field.
