Editor Interview: Sangamesh Gurappa Kumbar

Dr. Kumbar, PhD, is a tenured Professor in the Departments of Orthopedic Surgery, Materials Science & Engineering, and Biomedical Engineering at the University of Connecticut. His research focuses on synthesizing and characterizing novel biomaterials for tissue engineering and drug delivery. Specifically, his laboratory specializes in fabricating and studying micro nanostructures using semi-synthetic polymers, designed to enhance tissue regeneration and control drug delivery.

An active member of several professional societies, Dr. Kumbar has co-edited three textbooks and is an Associate Editor for Bioactive Materials and Journal of Biomedical Nanotechnology. He is dedicated to teaching and mentoring students at all levels, from high school to postdoctoral fellows.

Leveraging extensive research support from DoD, NIH, and NSF, he has spearheaded the development of innovative material strategies to investigate cell-material interactions and advance tissue regeneration. His ongoing projects include tendon and nerve regeneration using conducting polymers, and bone regeneration using cellulose-based scaffolds, disseminated in over 150 peer-reviewed publications.

Here's the interview we did with him:

Q: Could you briefly introduce your current research field?

A: My research focuses on the synthesis, fabrication, and characterization of micro and nanostructures using semi-synthetic polymers for tissue engineering and drug delivery applications. I am particularly interested in the development of novel biomaterials that integrate the advantageous properties of both synthetic and natural materials to promote enhanced tissue regeneration and controlled drug release.

Q: What obstacles or difficulties have you encountered in your research work? How did you overcome these difficulties?

A: Early in my career, securing consistent funding to support my research program was one of the greatest challenges I faced. The intensely competitive funding landscape often left me uncertain about the future of my work and where the next grant would come from. However, I was determined not to let these financial constraints derail my scientific ambitions. Through a combination of adaptability, resourcefulness, and sheer perseverance, I was able to overcome this obstacle. I actively diversified my research portfolio, exploring a wide array of funding opportunities beyond my primary area of focus. This flexibility allowed me to capitalize on emerging trends and interdisciplinary synergies, securing support from sources I may not have initially considered. Alongside these strategic efforts, I also learned to maximize the impact of the limited tools and materials at my disposal, becoming adept at creatively utilizing the resources available to me. Ultimately, it was my unwavering passion for discovery, combined with an unyielding determination to succeed, that carried me through these turbulent times. I understood that the path of a researcher is rarely linear, and I embraced the need to occasionally veer off course in pursuit of new avenues, knowing that this mindset, paired with relentless hard work, would enable me to not only survive those early funding hurdles, but to emerge stronger and more resilient than ever before.

Q: As an associate editor, what type of articles or which direction of research are you interested in?

A: As an associate editor, I am particularly interested in articles that describe novel biomaterials, innovative approaches to harnessing the best features of existing materials, and technological advancements that can aid in healthcare needs. I am also eager to review research that focuses on the development of new materials for tissue regeneration and drug delivery applications.

Q: What are your expectations for the future development of Bioactive Materials and its promotion of related fields?

A: In the future, I would love to see a stronger integration between bioactive materials and other disciplines, such as prosthetics and human tissue regeneration. I believe that the collaboration between engineers, clinicians, and material scientists is essential for advancing the field of tissue repair and regeneration. By bridging these different areas, we can develop more comprehensive solutions to address complex health challenges.

Q: What is your greatest hobby outside of scientific work?

A: My greatest hobbies outside of scientific work involve physical activities such as hiking, biking, and running. I find that these pursuits not only keep me physically fit, but also contribute to my mental and spiritual well-being. I also enjoy volunteering, as it allows me to give back to the community and gain a deeper sense of empathy and purpose.

Q: How do you balance scientific research work and personal life?

A: Balancing scientific research and personal life is an ongoing challenge, but I have found that compartmentalization and prioritization are key. I try to be intentional about setting aside time for both work and personal activities, and I am mindful of not letting one aspect of my life consume the other. When I need to, I'm also not afraid to postpone personal matters temporarily to focus on pressing research tasks.

Q: What do you think is the most important quality for researchers?

A: In my opinion, the most important qualities for successful researchers are curiosity, persistence, and an open-minded approach. Curiosity is essential, as it drives us to ask the right questions and explore new frontiers. Being observant and inquisitive allows us to identify promising research directions and uncover novel insights. Equally important is persistence, as research often involves navigating setbacks and obstacles. The ability to persevere in the face of challenges is crucial for making meaningful progress. 

Aside from those two qualities I feel it is important to emphasize having an open-minded approach. A belief of mine is that a successful researcher is one that is humble enough to admit what they don't know and be receptive to diverse perspectives and unconventional ideas. Additionally, self-awareness is key - without it, one risks becoming closed-off to criticism, which is the lifeblood of scientific growth and advancement. The combination of curiosity, persistence, and open-mindedness, undergirded by self-awareness, are in my opinion the most important qualities for researchers to cultivate. These traits empower us to ask the right questions, tackle difficult problems, and remain open to new ways of thinking that can lead to groundbreaking discoveries.
