Student Leaders

Juliana Carmack

I am a junior studying Civil Engineering with a prospective focus in structural and sustainable design. I plan to integrate renewables and natural energy flows into infrastructure, such as water flow through elevation and specified building placement/materials, to promote reduced energy consumption and the complete removal of carbon-based fuels. I hope to one day design buildings of this nature, which will lead me to a masters degree in sustainable design and/or architectural engineering.

When I’m not in school, I chase the beauties of life through travel, both in beautiful colorado and beyond. I hope that one day I will bring a sustainable motive to the multitude of places I visit and work in,

Brock Cross
Vice President

I will be finishing up my degree in mechanical engineering this May here at CU Boulder and I am very excited to serve the wonderful organization that is Tau Beta Pi my last year of college. I was born in New York, but my father served in the United States Army for the majority of my childhood so we moved around quite a bit. I have had the pleasure of seeing most of the country and meeting amazing people from all the places I have lived.

When I am not in the library, I enjoy skiing, hiking, fishing, and going to the gym. Also, I am currently working towards earning my private pilot’s license, as I have always had a passion for aviation. I have had two internships with Lockheed Martin – one as a mechanical engineer intern and the other as a systems engineer intern and I have enjoyed using the skills and knowledge learned in school to solve real world problems and help save lives.

James Schultz

I am a senior pursuing a BS degree in Mechanical Engineering with a minor in Computer Science and a certificate in leadership. My plan is to complete the bachelor’s Accelerated Master’s Program completing a master’s degree in Spring of 2022. During my time here at CU I have done my best to do everything I could during this once in a lifetime opportunity. I joined the Engineering Leadership Program (ELP) my freshman year which has since given me the opportunity to be a mentor for incoming students, an advisor on the student advisory council for ELP, and participate in a cultural immersion on a trip to Uganda and Rwanda. I have worked in the BOLD center as a tutor as well as the Idea Forge as a leading woodworking and sewing workshops.

Outside of school I like being outdoors and staying as active as I can. My favorite sport is probably basketball. You will likely see me at the Rec Center playing when I have some free time. I try to get to the mountains as much as I can whether it be for a hike, a camping trip or skiing. I enjoy going on bike rides, runs and anything that will get me outdoors really.
