I would pick the broad category of being an investigator. More than likely be a medical device engineer of whatever the specified area of expertise, which the clinical trial is being done. I like solving problems, therefore, being an investigator allows me to have a challenge set before me. The challenge of figuring out what the problem is and therefore conducting experiments for possible solutions. Being involved in the medical device development area as an investigator would motivate me to produce products that allow me to change the quality of life for those in need of a boost and to promote joy.
