Senior Design Expo: A Celebration of Ideas and Innovation

At the Senior Design Expo, students brought bold ideas to life.

Columbia Engineering hosted the 2025 Senior Design Expo May 8 in Roone Arledge Auditorium in Lerner Hall, where more than 40 projects were on display. Students provided real-world solutions to problems affecting women’s health, our environment, urban design and infrastructure, and medicine and health care. Projects incorporating robotics or addressing challenges in maternal and fetal health dominated the Expo. 

Fresh from their win at the Millard Chan Tech Challenge, the team behind MilkShaker demonstrated a practical and science-backed solution to prevent mastitis, providing professional level care without sacrificing time or requiring special training. Another group of seniors in the Department of Mechanical Engineering showcased a prototype for the CareCruiser, a wheelchair-to-stroller attachment designed to give wheelchair-using parents and caregivers greater independence when navigating with strollers and carseats.

Several projects also tackled infrastructure design, including a civil engineering and engineering mechanics team that unveiled Rethinking Resilience. The project envisions a new sustainable, flood-resilient train station to replace the existing Ardsley-on-Hudson station along the MTA’s Metro-North Hudson Line. 

And in the gaming arena, a team from the Department of Electrical Engineering demonstrated their physical tank game using modified remote-controlled cars. By reconfiguring the electronics of remote-controlled cars, the team enabled Bluetooth-based control of both the motors and onboard lasers. Players score by hitting opposing cars with laser pulses, while any car that gets hit is temporarily disabled with a five-second freeze penalty.

Dean Shih-Fu Chang greeted the students and commended them on their year-long efforts. “You all have started with an idea and brought it to life. That’s what engineers do! We bring ideas to life . . . Today’s showcase truly represents our Engineering for Humanity vision. This is a milestone in your Columbia experience and one I hope you remember for years to come.”

Each year, Columbia Engineering seniors work on a capstone project, aka Senior Design. They are challenged to solve real-world problems with innovative solutions, rooted in their foundational math, science and engineering courses. 

Here’s a look at some of the students and their innovations at Senior Design Expo 2025.
