Interview with Our PhD Graduate

What inspired you to pursue a PhD in this field?
 I have had a passion for research from a very young age, particularly research that digs into how things work at a fundamental level. Over time, I became interested in the way mathematics can describe and predict physical phenomena so precisely. That led me toward materials science, where understanding matter at the atomic scale is essential. A PhD allowed me to explore this through computational modeling—combining mathematics, physics, and the thrill of discovery.

 Why did you choose this department for your doctoral studies?
 My academic journey started here, and the department’s strengths aligned naturally with my research goals. With a strong foundation already built in physics, continuing here gave me the space to expand my knowledge and pursue advanced research. The supportive environment and emphasis on scientific inquiry made it the right place to grow as a researcher.

Could you explain your research in simple terms?
 My work looks at how materials change when very small atoms—like hydrogen—enter the spaces between their atoms. Though tiny, these atoms can drastically affect strength and other behavior. Since we cannot easily observe these changes experimentally, I used computer simulations to model the atomic structure and predict how the material responds. In short, I built a virtual material and watched how it behaved when different atoms were introduced. This helps us design stronger, more reliable materials for technology and industry.

What problem did your research attempt to solve?
 I aimed to understand how atoms like hydrogen, oxygen, and nitrogen—common in our environment—alter mechanical strength in materials. These atoms often cause distortions or weakening. My goal was to uncover why this happens and how we can better predict or prevent it.

What were your most important findings?
 My simulations showed that small interstitial atoms cause specific distortions in the atomic lattice, directly influencing mechanical behavior. I was able to identify which atomic sites are most affected and how these distortions lead to instability or degradation. These findings help explain materials failure at the atomic scale.

What was the biggest challenge in your PhD journey?
 Periods of uncertainty—especially when simulations failed or refused to converge—were the hardest. Limited computational resources also meant careful planning and optimization at each stage.

What kept you motivated during difficult times?
 My motivation came from curiosity and the desire to understand how materials behave at their most fundamental level. The excitement of discovery, along with guidance from my mentors and steady progress, even in small steps, kept me going.

What did you enjoy most about the department?
 The collaborative environment and academic rigor. Working alongside passionate peers and faculty created a space where ideas could grow. The department’s strong research culture helped shape me into an independent researcher.

What accomplishment are you most proud of?
 Reaching the finish line—completing my research despite challenges—is the accomplishment I’m most proud of. It represents persistence, growth, and years of hard work.

What advice would you offer to younger students?
 Stay curious. Be patient with progress—it often comes in small steps. Ask questions, seek guidance, and build both theoretical and practical skills. Most importantly, pursue what you love; passion will sustain you through difficulties.

This graduation marks not only the success of a dedicated researcher, but also the beginning of a new chapter for the Unit. We look forward to many more milestones, discoveries, and scholars who will push the boundaries of science in the years to come.
