It is obvious that real life does not always turn out what we expect it to. It applies to all the elements in life. Many things like school, work, career can be always perfectly planned but also can be instantly shifted, delayed or worse shattered, because of just like what COVID-19 has done to us all!
When I was in my undergraduate biotech program, I had so much interest in microbiology I thought I would one day have a PhD in virology and make vaccines. But opportunities came around and I took the risk to studying tissue engineering; as to this decade is still the state-of-the-art for growing/regenerating tissues. Although only few tissue engineered materials have been commercialized and reported successful in clinics, extensive research in the field holds a huge promise and carries an interesting multidisciplinary elements. And that's how I ended up in biomedical engineering.
