From Passion to Perseverance: My Journey to Earning a PhD

Updated date: 11/17/2024

Stepping into the unknown can feel daunting, but pursuing a PhD was a leap of faith fueled by an unwavering desire to make a difference. 

I began my doctoral journey at Erasmus Medical Center in 2013, driven by a passion for finding solutions to diseases like cancer. But, as life often proves, love alone isn’t enough—the challenges and how we navigate them truly shape us.

The Beginning: A Decision to Make a Difference

As a medical professional, I loved helping patients but could do more. The idea of becoming a scientist excited me. I wanted to contribute to research and discover solutions for illnesses like cancer. My decision to pursue a PhD wasn’t just a career move but a deeply personal mission. With that mindset, I embarked on my doctoral studies.

The Reality of Lab Life

The first year was an eye-opener. I spent countless hours in the lab, often overnight, running experiments and working with animal models. The emotional toll of growing tumors on mice and sacrificing them for research weighed heavily on me. I began to feel disillusioned and disconnected from my work, and the endless hours in isolation with lab equipment left me questioning whether this was my calling.

One day, I reached my breaking point and told my supervisor I couldn’t continue this research. It wasn’t well-received; I was warned that quitting the lab could jeopardize my graduation. The pressure was overwhelming. Misunderstandings with colleagues and homesickness compounded my struggles. I was spiraling into depression.

A Much-Needed Break

Thankfully, a close friend came to my rescue. They insisted I take a break and invited me to spend Christmas and New Year’s with their family in Cancun and Mexico City.

It felt risky, especially when my supervisor expressed concern about my safety in Mexico. This happens when people have preconceived ideas about a country or a group of people. But I chose to trust my friend, and it turned out to be one of the best decisions of my life.

The warmth of the holiday, the support of my friend’s family, and a complete change of scenery worked wonders for my mental health. I returned to my research, recharged and ready to pivot my focus.

Rediscovering My Purpose

After my break, I shifted my focus to a different area of research. I dove into the potential of magnetic nanoparticles in cancer treatment. My first paper was a turning point: I sought out collaborators, traveled to other cities to meet experts, and poured my energy into writing and refining my work. It wasn’t easy, but I was driven by an intense desire to succeed.

I contacted international professors for collaboration on larger projects, though not all efforts bore fruit. Rejections and setbacks were part of the process but didn’t deter me. I kept pushing, creating my research topics, and building a portfolio of publications that eventually led me to my thesis defense.

The Day of My Defense

The culmination of years of hard work came on my graduation day. Standing before the doctorate board and defending my thesis felt surreal. The discussion was rigorous, but it was also a moment to showcase my journey and the depth of my research.

Hearing the words, “I grant you the title of doctor,” was overwhelming. My promoter handed me the diploma, and I was officially Dr. Li. It was a moment of pride, gratitude, and reflection on the hurdles I’d overcome.

Huge thanks to my lovely and kind Mexican family’s support.

Lessons Learned

Throughout this journey, I learned that success is rarely linear. Challenges, doubts, and even failures are inevitable, but they don’t define you—your persistence does. I realized the importance of taking breaks, seeking support, and being willing to adapt. 

This experience wasn’t just about earning a degree; it was about growth, resilience, and finding my place in a field where I could make a meaningful impact. Looking back, I’m proud of how far I’ve come and excited for what lies ahead.

A Message of Gratitude

To my friends, family, and colleagues who supported me along the way, thank you. Your encouragement and belief in me made all the difference. To anyone facing their own challenges, remember: it’s okay to pause, reevaluate, and find a new path. The journey may be tough, but the rewards are worth it.
