Katherine Tsui and James Dalphond

Katherine Tsui and James Dalphond met at the University of Massachusetts Lowell, from which they graduated, and where the groom received a master’s degree in computer science, and the bride both a master’s degree and Ph.D. in that subject.

Ms. Tsui and Mr. Dalphond grew up only a mile away from each other in Dracut, but they did not meet until they were graduate students at the University of Massachusetts Lowell.

With a shared interested in robotics, they worked in adjoining labs, occasionally partnering on robotics outreach events.

“While I find most software engineers to be a bit introverted, I thought James was really smart and very sociable and outgoing,” Ms. Tsui said. “I tend to keep a very close circle of friends, and he quickly began entering that circle.”

In summer 2014, they took some time away from the lab but began collecting data on each other while backpacking and camping in Nova Scotia.

“I found James to be a very organized person who is a lot of fun to be around,” Ms. Tsui said. “He also had a very dry, sarcastic sense of humor, like I do.”

They began taking similar trips — “We’re both very outdoorsy and love the ocean,” Ms. Tsui said — and she became that someone he most enjoyed having in his camp.

“Her curiosity is what makes her stand out,” Mr. Dalphond said. “I have seen her sit down on a hike and stare at a clump of moss and why it’s in that particular place before we can move on, and I enjoy watching how much she can enjoy figuring stuff out.”

After completing her Ph.D. in October 2014, Ms. Tsui moved to Guilford, Conn., to take a postdoctoral position at a social robotic lab at Yale, but maintained a long-distance friendship with Mr. Dalphond, who continued his research at the University of Massachusetts Lowell. Two months later, they were officially dating.

“I loved his willingness to come and see me on a moment’s notice and throw hot dogs on the grill or go for a long drive and explore new places together,” Ms. Tsui said.

Their relationship continued to blossom, and in October 2016, Ms. Tsui and Mr. Dalphond moved into an apartment together in Watertown, Me.

In February 2018, they attended a Valentine’s Day event at the New England Aquarium called “That’s A-Moray,” where people could leave messages for their dates on plastic fish suspended in the Giant Ocean tank.

On one of those fish, Mr. Dalphond wrote: “Kate Tsui, will you marry me?”
