Capstone Project Abstract

NIBCO is a recognized global leader in the manufacturing and distribution of valves, fittings, and comprehensive flow-control products across diverse industrial sectors. This capstone project investigates the feasibility of expanding NIBCO’s valve presence into the cryogenic valve market. Cryogenic flow-control technology is critical for safely managing liquefied gases, such as liquid natural gas (LNG), oxygen, and nitrogen, in extreme operating environments ranging from -150°C to -196°C. Entering this market presents extreme technical complexities and requires rigorous, independent third-party safety and performance certifications. This project aims to determine if a defensible go-to-market path exists for NIBCO in this space by deconstructing market urgency, supply chain friction, and barriers to entry. To achieve this, the student will conduct primary customer discovery across key market actors, such as Lead Specifying Engineers and Industrial Pipe, Valves, and Fittings (PVF) distributors. By engaging these segments, the student will evaluate the viability of NIBCO’s core value propositions against the requirements of onboarding a new manufacturer. Ultimately, the project will deliver either a validated Ideal Customer Profile (ICP), competitive landscape analysis, and comprehensive go-to-market strategy, or a rigorously documented negative finding detailing why the barriers to entry are too high to warrant investment.

I am excited about this project because it operates at the intersection of highly technical engineering and strategic business development. The opportunity to drive primary discovery in a high-stakes industry means my findings will directly influence a major investment decision for a global manufacturing leader.

Why did you choose ESTEEM?

I chose ESTEEM to bridge my technical background in mathematics and engineering with the business and entrepreneurship skills needed to bring human-centered solutions to life. My experiences taught me that the best technical systems are ultimately measured by how well they serve people, and ESTEEM’s focus on customer discovery and commercialization provides the perfect framework to translate complex problems into real world value. Furthermore, returning to my alma mater allows me to learn alongside an incredible cohort that shares the distinct Notre Dame mission to use technology and innovation as a force for good.

What do you hope to do after ESTEEM?

After ESTEEM, I plan to pursue opportunities where I can apply systems thinking and business strategy to develop and deliver better solutions, whether that means building a new product, improving an operation, or solving a complex business problem.

What do you like to do in your free time?

I am drawn to outdoor pursuits, especially hiking, but enjoy everything from rock scrambling to ATVing and skiing. I value both the challenge and the shared experiences that come with them. I stay active through ultimate frisbee, strength training, and a focus on nutrition. I enjoy traveling and experiencing different cultures through their food. On a quieter note, I appreciate reading, photography, and spending time with friends while watching a good movie.
