How I Switched Fields Within Biomedical Sciences

In 2007, precisely during the early first practical classes that I attended in Physiology and Pharmacology, I began to admire working in the laboratory with my glowing white lab coat. From there I started developing a passion for academics and research, but I had no clue what I needed to do to become an academic research scientist. However, I ensured that I maintained cordial relationships with some of the lecturers and lab scientists in my department. It did not take me so long to learn some of the nitty-gritty of research e.g., study design and data analyses, as a student. Before I graduated, I was already assisting some of the final-year students in my department with their projects and thesis writing.  I started my career journey in academic research when I performed a study on Magnifera Indica (1). This area focuses on ethnopharmacology. After I graduated with my first degree in 2010, I enrolled for my Masters degree in Pharmacology. The master’s degree was about 70% research work and 30% coursework.

During this time, my interest in academic research grew rapidly. I got involved in many projects and co-supervised undergraduate students. Occasionally, I volunteered to give tutorials in neuropharmacology. I also assisted postgraduate students in their thesis works. Overall, by then, my research work has expanded beyond ethnopharmacology to neuroscience and toxicology. For example, investigated the anti-inflammatory properties of bioactive compounds e.g., Jobelyn® and some other plant extracts (2–4). One of the studies that caught my attention most at that time was the investigation on monosodium glutamate toxicity because the study revealed some important insights that are quite relevant to the etiologies of various diseases e.g. metabolic disorders (5). Apart from that, I led an investigation into the anti-stress properties of Methly Jasmonates (6,7). At this stage in my career, I knew that I already had a solid foundation for an academic research career. Nonetheless, I did not know what lay ahead for me in the vast growing scientific fields.

Indeed, my interest in anti-stress and neuroscience stirred me towards investigating Parkinson’s disease. I started developing an interest in understanding the genetics, molecular and functional etiologies of the disease. This passion led me to secure a PhD position to investigate the genetics of Parkinson’s disease. I investigated both the epidemiology and the genetics of the disease during my PhD(8). During my PhD programme, I developed advanced data science skills, bioinformatics, science communication and clinical research. After the completion of my PhD in 2019, I realized that I had successfully switched careers within biomedical sciences. The new skills that I have acquired allowed me to perform various clinical and data analysis studies. For example, I investigated various aspects of hearing impairment genetics during my first postdoc  (9–15).

To date, I do not feel that I have switched fields because I am still connected with my formal studies maintaining knowledge and gaining new insights. The field of biomedical sciences is so interwoven that one must be confident to switch around particularly if they are an interest. I am so glad that I developed my passion and got the support that I needed to switch fields to human genetics because I am enjoying what I am doing now and what I have done in the past in the domain of biomedical sciences as I see both lines and dots joining together to make me a prolific genomic medicine scientist.
