What does Katherine Zhu do for a living?

She is very sporty and in November 2023 ran her first half marathon.

How did Collin Morikawa meet Katherine Zhu?
The golfing power couple started dating in April 2017.
Morikawa posted their first photo together on social media the following month and joked: "Probably not a good idea to take your date to a rooftop when she's afraid of heights."
The pair met through golf at college, despite going to different universities.
While she went to Pepperdine, Collin attended the University of California, Berkeley.
In a video for the PGA Tour, the pair gave a bit of a background to their relationship.
Morikawa said: "We met in college and just clicked.
"It's crazy because I won my first college tournament that next week and we've done pretty good since - it's really fun.
Zhu admitted their relationship is "very competitive" when they hit the course together with Morikawa adding: "Always, we never let each other win.
"I think she beats me on probably 70 per cent of our chipping competitions.
"It actually makes me a better player.
"Most importantly, golf has created opportunities that have made lifelong memories that I’ll cherish forever. I’m so grateful for this amazing game."

"What's great about her is that we're always competing.
"To have her around [on the PGA Tour] on off weeks when no one's around, she can always bring a wedge to the course and we can always do something fun."
Katherine has a huge following on Instagram, with close to 75k as of April 2024.
Like any happy couple, Morikawa and Zhu love going on dates.
The couple can be seen exploring cities where he is playing tournaments, adventuring in the countryside, wining and dining at plush restaurants or, their personal favourite, a day at the beach.
The pair were engaged in November 2021, and the two tied the knot a year later at a lavish ceremony with their dog Koa on November 26, 2022.
Does Collin Morikawa's wife play golf?
Katherine spent four years playing golf at Pepperdine University, earning multiple WGCA All-American honours.
She loves her man and the sport so much she is often spotted on the PGA Tour caddying for him during competitions.
She said: "Golf is such a big part of my life.
"It’s taught me to be strong when things aren’t going well. It’s taught me to respect others around me.
"Most importantly, golf has created opportunities that have made lifelong memories that I’ll cherish forever. I’m so grateful for this amazing game."
Katherine supported her then-fiance at the PGA Championship in August 2020.
During the event, being played in San Francisco, she fitted in a trip to the Golden Gate Bridge, but ensured she was back at the course as he swept aside the competition to land the title at the first time of asking with a final-round 64.
SHOE-WEARING DOG
Coronavirus rules led to a slightly awkward high-five celebration at first before a big hug.
And after Morikawa dropped the lid off the Wanamaker Trophy, Zhu joined him to pose with it together.
In 2021, she was back supporting him as he lifted the Claret Jug at The Open.
She posted: "So incredibly proud of you!
"You’ve accomplished so much since turning pro in 2019 and I really can’t wait to see what’s next."
