Tell us about your journey to graduate school and what led you to NC State.<\/strong>
My journey to graduate school has been an interesting amalgamation of academic curiosity, a passion for problem-solving, and the pursuit of impactful research. Choosing the right institution was crucial for me, and that’s where NC State comes in. I was particularly drawn to the Wilson College of Textiles, which is recognized as the premier institution for textiles in the world. The excellence that permeates the department, both in terms of research and education, made it an obvious choice for me. I was not only looking for strong academic programs but also an environment that fosters innovation and real-world applications. NC State and the Wilson College of Textiles offer just that: world-class faculty, state-of-the-art facilities, and research opportunities that are second to none. Therefore, the decision to join NC State was easy, fully aligned with my career aspirations and academic goals.<\/p>\n\n\n

Tell us about your research and\/or teaching experience.<\/strong>
My research is focused on developing advanced pH sensors based on the optical properties of single-walled carbon nanotubes (SWCNTs). The core of this work aims to address a wide range of biomedical and environmental applications where accurate and reliable pH sensing is critical. We have successfully developed a pH sensor that can detect a pH range of 2-10, which is a considerable advancement in the field, offering more extensive applicability compared to existing solutions.<\/p>\n\n\n

One of the significant milestones of our research is the establishment of a library for pH sensing using various surfactants or polymers. By tailoring the surface of SWCNTs, we have modified the sensor’s responsiveness towards pH changes, enhancing both sensitivity and selectivity.<\/p>\n\n\n

Additionally, we’ve incorporated these SWCNT-based sensors into a hydrogel platform. The hydrogel-based sensors show promise for practical applications like wearable patches or as components in wound healing technologies. This development could revolutionize point-of-care diagnostics and personalized medicine, offering real-time, continuous data collection.<\/p>\n\n\n

My team and I have spent considerable time studying the photoluminescence properties of SWCNTs, particularly how their chiral angles influence their characteristics. This deep understanding has enabled us to develop more accurate and efficient sensors.<\/p>\n\n\n

My teaching experience has been comprehensive, involving active participation in traditional classroom settings. I have engaged in teaching, grading, updating course modules, and creating questionnaires. Parallel to this, my research role has encompassed significant mentorship, where I’ve guided younger researchers in the laboratory. I have instructed them on experimental design, data analysis, and conveyed the broader implications of our work on society and technology.<\/p>\n\n\n

Overall, my research not only pushes the boundaries of fundamental science but also has direct implications for healthcare, environmental monitoring, and the economy, making it both a scientific and socially impactful endeavor.<\/p>\n\n\n

How has the Graduate School and\/or NC State helped you with your professional development?<\/strong>
The Graduate School and NC State have been instrumental in my professional development in multiple ways. First and foremost, the interdisciplinary approach adopted by the institution has provided me with a robust academic foundation. I’ve been able to work alongside experts in materials science, biomedical engineering, and chemistry, which has greatly enriched my research perspective and methodology.<\/p>\n\n\n

Furthermore, the availability of state-of-the-art research facilities and laboratories has been invaluable in advancing my project work. From high-resolution microscopy to advanced spectroscopic techniques, the tools at my disposal have enabled me to explore novel research questions with a high degree of precision and accuracy.<\/p>\n\n\n

Professional development seminars and workshops organized by the Graduate School have offered practical advice on career development, publication, and grant applications. These sessions have filled in gaps that traditional academic coursework often does not cover, preparing me for the rigors and expectations of a professional research career.<\/p>\n\n\n

Another highlight has been the networking opportunities. Whether it\u2019s the faculty members who have become mentors, the industry professionals I’ve met during events, or the peers who have become collaborators, the relationships I’ve built at NC State will undoubtedly have a lasting impact on my professional journey.<\/p>\n\n\n

Lastly, the emphasis on outreach and communication skills has helped me understand the significance of making complex scientific research accessible to the general public, an essential skill in today\u2019s fast-paced, information-savvy world.<\/p>\n\n\n

In summary, the holistic educational experience at NC State has been much more than just academic enrichment; it has been a comprehensive program designed to mold well-rounded, competent professionals ready to tackle the challenges of the modern world.<\/p>\n\n\n

What advice do you have for new or current graduate students?<\/strong>
Certainly, navigating graduate school is a multi-faceted journey that requires more than just academic prowess. Based on my experience, here are some pieces of advice for new or current graduate students:<\/p>\n\n\n

Start with a Clear Vision: Have a clear understanding of your research goals and what you aim to accomplish during your time in graduate school. This vision will serve as your guiding light when things get tough.<\/p>\n\n\n

Choose Advisors Wisely: Your advisor will be more than just a supervisor; they will be a mentor, a confidant, and a significant influence on your academic and professional life. Make sure to choose someone whose work you respect and with whom you can maintain a good working relationship.<\/p>\n\n\n

Work-Life Balance is Crucial: It’s easy to get lost in the world of academia and forget about your well-being. Make sure to allocate time for your hobbies, family, and mental health.<\/p>\n\n\n

Networking: Take advantage of conferences, seminars, and other opportunities to meet people in your field. Networking can open doors that you didn’t even know existed.<\/p>\n\n\n

Interdisciplinary Skills: The more versatile your skill set, the more valuable you are. Don’t shy away from learning new methods or tools that could augment your main line of study.<\/p>\n\n\n

Communication is Key: Whether it’s communicating your research to a lay audience or writing a compelling grant proposal, effective communication skills are as important as your research skills.<\/p>\n\n\n

Accept Failure: Not every hypothesis will be validated; not every experiment will work. Failure is a part of the research process. What’s important is that you learn from it and move forward.<\/p>\n\n\n

Time Management: This cannot be emphasized enough. Juggling coursework, research, and personal life requires excellent time management skills. Use tools and techniques to help you stay organized.<\/p>\n\n\n

Seek Support: Never hesitate to ask for help, whether it’s from your advisor, your peers, or professional counselors. Graduate school can be overwhelming, and it’s entirely okay to seek support.<\/p>\n\n\n

Enjoy the Process: Last but not least, try to enjoy your time in graduate school. It’s a unique period of your life where you get to focus so deeply on a subject you are passionate about. Take pride in the small victories, and don’t lose sight of why you started this journey in the first place.<\/p>\n\n\n

Graduate school is not just an advanced degree; it\u2019s an experience that will significantly shape your personal and professional life. Make the most of it!<\/p>\n\n\n
