A little about me

Always learning.
Always becoming.

Hi, I'm Ammy Lin, a data enthusiast, musician, and reader, among other things. I'm currently a master's student in Interdisciplinary Data Science at Duke University. Before that, I graduated from Carleton College with majors in mathematics and Chinese and a minor in music performance.

I'm passionate about learning and spend a lot of time thinking about the relationships and role of the individual within society, as well as ways to live life more purposefully. 

I love many things, including, but not limited to, jogging, journaling, sunrises, thinking of the perfect present for someone, books, playing musical instruments, the sound of rain, volunteering, real numbers, watching funny YouTube videos, interesting words, listening to podcasts, slow bike rides, playing the piano, dim sum, traveling, nature walks, listing hobbies, blue skies, and learning about different cultures.

Ideas, Principles, and Values That I Live By

  • Live with compassion. Simple but necessary for society and for the self. I think about the fundamental attribution error described in psychology, which states how it is difficult to justify the actions of others through situational factors but how it is easy to excuse our own actions with flexible explanations. While it is difficult to avoid making this error completely, I believe that it is easier to understand others if compassion and empathy are emphasized as important values. By working together, we build the bridges for success and we stand to gain more than we lose. Likewise, self-compassion is a crucial ingredient for happiness and positive growth. A majority of internal dialogue is negative, but I think that we deserve more credit than we give ourselves, at least, most of the time.
  • Happiness is not a destination. In day-to-day conversations, happiness is often referred to as a faraway goal to achieve, almost like an unattainable piece of fruit on a tall tree. Instead of striving to "reach" happiness, I try to find happiness in everyday moments, aided by gratitude and mindfulness, and try to define happiness on my own terms without judgment or comparison with others. "A happy life is just a string of happy moments. But most people don't allow the happy moment. Because they're too busy trying to get a happy life." -Abraham Hicks
  • Growth occurs in the stretch zone. Thinking back, a majority of the most illuminating moments in my life occurred when I was doing something outside of my comfort zone, where I had a greater area to explore and understand. Saying yes to something that brings that slightest bit of discomfort is paramount to personal development. This can also be related to accepting criticism as a tool for improvement. While my ego sometimes gets in the way of admitting my faults, in a way, it takes courage and humility to step back and acknowledge criticism as valid and growing from it.
  • The power of tiny gains. The author James Clear writes about the power of continuous improvement, where small improvements add up in the long term. By aiming to improve by even just 1% every day, the small changes add up to great growth. After all, the goal is progress, not perfection. "Continuous improvement is better than delayed perfection." -Mark Twain
  • Knowledge is the key to a fulfilling life. Embarking on a constant journey of growth includes opening the mind to learning new information, which helps us see the world through different lenses and makes us better overall. It is impossible to know everything about our universe, but by recognizing our shortcomings and gaps in knowledge, it becomes easier to make a blueprint to fill in these gaps and more.
  • Be present and make room for stillness. Our world today seems to be filled with unmet objectives, a never-ending list of deadlines, and hours upon hours of media that is waiting to be consumed. Sometimes we forget to look up and appreciate the little parts that make up our surroundings. Stillness is staying balanced while the world twists around you, to live at a steady pace, to be able to take a step back and reflect, and to possess tranquility even when your surroundings seem to be filled with chaos. Understanding that it is okay to slow down and take things at your own pace is something that I believe is essential for stillness, which consequently leads to a more fulfilling life. "Don't reject a difficult or boring moment because it isn't exactly what you want. Don't waste a beautiful moment because you are insecure or shy. Make what you can of what you've been given. Live what can be lived. That's what excellence is. That's what makes presence possible." -Ryan Holiday

Liberty Mutual Insurance · Boston

Graduate Data Science Intern

I spent the summer of 2026 at Liberty Mutual in Boston. My project combined features from claim photos with a structured-data score in a LightGBM model to improve early total-loss detection. I used Optuna to tune the model and worked on validation that avoided data leakage. Ablation studies and SHAP analyses helped me check where the photo features added useful information and understand the model’s limits.

A few other things

Fun facts.

I’ve been to the National Spelling Bee. Twice.

In 2015 and 2016, I qualified for the National Spelling Bee, and those two experiences in Washington, D.C. have changed me forever. It opened my eyes to a wider world filled with all types of curiosity, where people were not afraid to pursue their dreams.

The story behind my love of words ↗

“Band or orchestra?” “Both!”

I started learning the flute and viola when I was a sixth grader at Forestview Middle School. Before that, I played the piano and wanted to try something new. At Carleton, I joined the Chinese Music Ensemble and picked up the dizi (Chinese bamboo flute).

A kitchen experiment: five-nut mooncakes.

In 2024, I made five-nut mooncakes for the Mid-Autumn Festival, and they turned out deliciously (like, seriously, the best mooncakes I’ve ever had…but maybe I’m biased)!

A few thoughts, and mooncakes ↗

I like keeping the little moments.

I started recording one second of my day in 2018. As I wrote in 2021: “The small things become more significant, and each day feels as special as the last since they all get the same time value of one second.”
