What did you do for graduation/post-graduation?

I completed my M.Tech in Laser & Optical Engineering from College of Engineering-Guindy (Anna University), Chennai, which gave me a strong foundation in optics and laser applications. Before that, I earned a B.E. in Electrical & Electronics Engineering from Dr. N.G.P Institute of Technology. My interest in optics deepened during my post-graduation, where I got hands-on experience with optical systems, lasers, and precision engineering.

What were some of the key influences that led you to such an offbeat, unconventional, and unique career in Optical Engineering?

After completing my undergraduate degree in Electrical & Electronics Engineering, I secured a reasonable score in the entrance exam for post-graduation. While many opted for mainstream fields, I wanted to explore a domain where physics plays a crucial role in technological advancements. After thorough research, I chose Laser & Optical Engineering at Anna University, as only a few institutions offered this specialization.

The principles of light-matter interaction, wave optics, and photonics fascinated me, and I saw immense potential in the applications of lasers and optics across various industries. With emerging advancements in medical diagnostics, imaging systems, and laser-based technologies, I believed this field would shape the future of innovation. This decision not only aligned with my passion for physics but also enabled me to contribute to cutting-edge developments in ophthalmic optics and precision engineering.

During my postgraduate studies, I had strong support from my friends, Mr. Kamal and Mr. Marimuthu, as well as my UG HOD, Mr. Kumarchinnaiyan. Their encouragement and guidance played a crucial role in helping me pursue my M.Tech in Laser & Optical Engineering. Their belief in my potential motivated me to specialize in optics and build a career in this field. During my academic years, I was fascinated by the role of optics in medical devices, especially in ophthalmology. The ability to design and develop optical systems that improve vision diagnostics and treatment motivated me to pursue this field. My curiosity about how light interacts with different materials and the impact of precision optics in healthcare guided my career choice.

How did you plan the steps to get into the career you wanted? Or how did you make a transition to a new career? Tell us about your career path.

I strategically planned my career by focusing on optical design, fabrication techniques, and diagnostic device development. My journey began with hands-on experience in optical manufacturing at Appasamy Associates, where I learned the fundamentals of precision optics. 

After my MTech, I joined Appasamy Associates Pvt. Ltd. as a Product Development Engineer, where I gained in-depth knowledge of precision optical components such as lenses, prisms, filters, and mirrors—all of which play a crucial role in optical and ophthalmic equipment.
