When did you join John Zink?

I joined John Zink in 2013 straight out of college. My master’s degree research topic was oxygen-enriched combustion of biodiesel fuels. As part of my coursework, I had the opportunity to take a class entitled “Applied Combustion” that was taught by John Zink engineers from the various product groups. These instructors were animated, excited, and knowledgeable. This led me to apply to John Zink as I wanted to be part of that team.

Can you describe an impactful project you’ve worked on that highlights John Zink’s commitment to advancing technology and environmental stewardship? What was your role in it?

I joined the development of the SOLEX™ burner in its late stages as the engineering support for finalization and commercialization. The SOLEX burner is the newest and lowest NOx emission process burner that John Zink offers. It is a step change in the emissions performance. This was enjoyable work as this burner operates fundamentally different from our other offerings. I personally developed the calculations required for controlling the burner and have personally supervised the startup of the first installations. This greatly extended my knowledge of plant operations, P&IDs, and controls.

What advice would you give to someone considering a career at John Zink? What should they expect and prepare for?

Just for fun, can you share the most memorable meal you’ve ever had and the story behind it?

I have had the recent opportunity to travel to South Korea for business. Among the many interesting meals that I ate there was one called “steamed shell”. There were many variants of this dish, but the one that was the most memorable included various shellfish that were still moving as you cooked them in a pan at your table. Once cooked…it was delicious.

What is a personal passion or hobby that you’ve been able to incorporate into your work?

A personal passion of mine is traveling and exploring new places, and I’ve been fortunate to incorporate this into my work at John Zink. Visiting customers around the world allows me to see unique locations and experience different cultures, which not only enriches my personal life but also helps me build stronger relationships with clients and bring fresh perspectives to the work we do.

Let’s end with something fun – what’s the most memorable meal you’ve ever had, and where was it?

The most memorable meal I’ve ever had was at Le Jules Verne, a Michelin-starred restaurant located in the Eiffel Tower. Not only was the food divine (one entire course was cheese and bread), but we also had the most breathtaking view of Paris from high inside the tower!
