I would opt for the role of a Clinical Research Associate (CRA) if I were to take part in a clinical research. With this role, I would be responsible for running clinical trials so as to test the effectiveness, benefits, and risks of drugs in an effort to ensure that they are safe and can go on the market. Basically, I will be involved in all the stages of a clinical trial, executing roles such as identifying and setting up an investigational site, planning, monitoring, and even closing down the trial. The main reason why opted for this role is that I will be directly involved in ensuring that the drugs entering the market are absolutely safe. There have been some cases of unsafe drugs getting into the market, and taking up this role of a Clinical Research Associate (CRA) would mean that I would address this issue.
