What inspires you about your research?
Globally, landfills are the principal means of safely disposing of municipal and hazardous waste materials. Even though landfills are typically well-engineered systems, the lining at the base of a landfill may still fail to adequately prevent leachate contamination and the possibility of hazardous materials seeping into groundwater. This poses significant risks of hazardous materials leaking into nearby water bodies and coastal areas, potentially harming human health and the ecosystem.
My research aims to develop an environmentally safe approach toward construction of hydraulic barrier liners for hazardous municipal waste containment facilities. Biochar and polymer are the key sustainable materials used in this research. Currently, biochar is recognized as an innovative landfill barrier material due to its filtering properties, low volumetric shrinkage and high water-holding capacity. Likewise, the polymer has low cost, low biodegradability, a nontoxic nature, cementitious behavior, and the ability to adsorb heavy metals. A safe barrier system will retain landfill gas within the containment system and have the potential to combat climate change. Moreover, in this research, I investigate the feasibility of biochar and polymer in reducing shrinkage and cracks in landfill liners. Landfill liners are vital in preventing leachate leakage into the surrounding soil and groundwater, thus minimizing environmental contamination. These enhancements in landfill liner construction can contribute to more sustainable waste management practices, crucial for safeguarding coastal areas and marine ecosystems in British Columbia, Canada, and beyond.
Why did you decide to pursue a graduate degree?
Civil engineering inspired me at a young age. I thoroughly enjoyed my undergraduate program and always wanted to learn more at an international level. I joined Nepal Electricity Authority after completing my undergraduate degree from Tribhuvan University, Nepal. While working there, I developed a keen interest in the stability, safety, and sustainability of power infrastructure amidst the challenging geological and environmental conditions of Nepal. The shortage of geotechnical experts in Nepal inspired me to pursue a master’s degree in this field. I am truly grateful to my supervisor Dr. Siddiqua for providing me with an opportunity in her lab. As a graduate student, I am learning advanced technical skills, and about cultural safety, a respectful working environment, equity and inclusion, and Indigenous peoples and cultures.
Why did you decide to study at UBC?
I aspired to attend a university where I will have access to state-of-the-art research facilities, and I can be under the constant tutelage of erudite scholars in the field of Geotechnical Engineering; UBC is the ideal place to foster my interest in my chosen field. The research at UBC often emphasizes sustainable practices in engineering, which aligns with global trends towards environmental responsibility and climate resilient infrastructure. During my search for a prospective supervisor, I got in touch with Professor Sumi Siddiqua who is a leading researcher in sustainable geotechnics and a role model for women in engineering. Joining UBCO and working as a research assistant with Dr. Siddiqua has given me an incredible opportunity to pursue my graduate degree in a well-rounded environment.
What do you enjoy about your program?
I always had a strong passion for mathematics and engineering. In engineering research, there is a continuous push to innovate and improve existing technologies. My current focus is on developing composite materials that offer superior performance and lower costs compared to traditional landfill liner construction methods. This work combines environmental considerations with the potential for significant positive impacts on public health, which motivates me greatly in this research area. I enjoy discussing my project with my peers in our research group. We learn from each other, and there is a collegial knowledge-sharing environment that ignites the thrust for impactful research outcomes.
What aspects of your life or career before now have best prepared you for your UBC graduate program?
My academic background, a Bachelor’s Degree in Civil Engineering, gave me a strong foundation in engineering principles. My previous work in civil engineering roles in public utility organizations helped me to develop effective communication skills and manage multiple tasks while meeting deadlines, especially in a collaborative environment. Overall, a combination of academic achievements, relevant work and research experience, and a passion for engineering work prepared me well to thrive in graduate school at UBC.
What advice do you have for new graduate students?
Starting as a new graduate student can be both exciting and challenging. Graduate school is a journey filled with endless opportunities for growth and learning. Embrace every experience and make the most of it, while also prioritizing your mental health. Remember, it’s important to find balance and support as you navigate this transformative time.
What do you do for fun or relaxation?
I am originally from Nepal. Being far from home was indeed challenging in the early days, especially when starting a new chapter like graduate school in a different country. Having my husband with me has significantly eased the transition. In my spare time, I love cooking, participating in adventurous activities and spending time with my loved ones, especially friends and family. Additionally, I am exploring Canada’s diverse cities and lakes, embracing new experiences, meeting people, and immersing myself in the rich cultural tapestry that Canada offers. Outside the lab, these activities not only help me unwind but also add meaning and fulfillment to my daily life.
Where do you hope your degree/research will take you next?
Pursuing a graduate degree and engaging in research at UBCO has been a rewarding and multidimensional experience. With my degree and acquired research experience in geotechnical engineering, I hope to embark on a path that bridges technological innovation and sustainable infrastructure development. My passion for understanding soil behavior drives me to pursue more advanced research in geotechnical engineering. I envision contributing to research and projects that address the challenges of urbanization, climate change, and natural disasters, whether through academia, industry, or a collaborative research institution. By improving my skills and knowledge, I aim to develop and implement solutions that not only advance the field of geotechnical engineering but also have a meaningful and positive impact on the built environment and communities around the world. Ultimately, I aspire to be at the forefront of developing sustainable and resilient infrastructure, helping to shape a safer and more sustainable future for generations to come. As I have learned from my supervisor, I carry a profound responsibility as a woman engineer to make the journey welcoming for young girls who may decide to follow in my footsteps.
