Balancing expertise and growth in a postdoc
I am a new postdoc who switched research focus from hypertension to urology, and I would be happy to provide some insight into this topic. As a recent PhD graduate, you are an expert in a specific research niche, under a broader umbrella topic. For example, during my thesis work, I became an expert in kininase I signaling and its proposed pathological roles in the development of hypertension and end-organ damage. While I am an expert in neurogenic forms of hypertension, I would not classify myself as an expert in pulmonary or gestational hypertension, since the etiology is different. Additionally, with novel findings being published every day, achieving expert status in a broad topic may be challenging, but it is important to prioritize your time and to be realistic with your career and research-based goals. In reality, a postdoc is fundamentally a training-focused position designed to help hone your skills and experience, and to work towards becoming a successful independent researcher.
Benefits of pivoting research fields during as a postdoc
Learning new topics at the postdoc stage can be daunting. However, it can also yield several benefits such as expanding your skillset, bridging gaps between separate research areas, enhancing collaboration, and growing your network. Oftentimes we overlook the transferrable skills we possess, like our ability to learn new protocols, critical thinking, data analysis/interpretation, and more. These transferrable skills will be useful throughout your career in research, and even other aspects of life, leveraging these skills can help you learn a new discipline. Moreover, it is important to identify where your gaps in knowledge lie within the new area and fill in the blanks. This will take time and a substantial amount of effort to achieve. However, once you have a strong foundation in the new research field, you can then identify gaps in knowledge and use your previous expertise to propose novel directions which bridge these separate areas of research together. This provides a unique opportunity to make a major impact on research. Lastly, as a postdoc you have already garnered a network of collaborators, but in the new research area you may not have those connections yet. To address this, it is important to rely on your PI which often times will promote and guide you to expand your network and collaboration opportunities. I also suggest you attend meetings, seminars, and volunteer to increase your network. With anything new, there will be a learning curve, but it is not impossible if you rely on the tools that are available to you.
Understanding what is expected of you
It is important to understand what is expected of you as you enter a new postdoc opportunity. Have open communication with your mentor, and ask them whatever questions you may have. Be open to constructive feedback as we are all striving to become better researchers. Ultimately, your mentor is there to help you improve and reach your goals. Although you may not start as an expert in a topic, if you are willing to learn, receive instruction, and retain information, you can reach expert status. Lastly, the world of science is vast and full of possibilities, and you can make your mark in any area that sparks your curiosity!
