Personal Picture

Hi, my name is...

Alvan Caleb Arulandu.

I'm 17 years old.

I consider myself a researcher, developer, and hobbyist who enjoys exploring our universe through code and creativity. Currently, I'm studying Math + CS at Harvard University ('27) while working on some exciting personal projects!

research background


With a background in machine learning and differential equation modeling, my research interests include dynamical systems and theoretical computer science. Recently, I became a Regeneron Science Talent Search Scholar for my work using physics-informed neural networks to inform infectious disease policy. I would say something profound, but I'll leave you with this instead:

I wrote my first line of code on Khan Academy when I was 7. Today, I am a AWS Certified Solutions Architect Associate and have also received a Certificate of Quantum Excellence from the IBM Qiskit Global Summer School in 2021 and 2022. I enjoy using the power of software to solve community problems, explore computer science rabbit holes, and unleash my curiosity in personal projects.

Hobbyist | Game Development

Growing up on the Nintendo 3DS, games captivated my attention as a budding computer scientist. I see game development as the prime example of interdisciplinary work. In the process of making games I love, I get to explore super cool algorithms like Delanuay triangulation and learn a wide variety of creative software at the same time!



Flighty: a multiplayer 1v1 dog-fighting game with intuitive mouse controls and fast-paced action. (in-development)


Bussin': a fast paced racing game where you play as a bus driver trying to drop off as many kids to school as possible!

Young Game Developers Association (YGDA)


An uplifting community of young developers interested in game development: the intersection of art, math, computer science, and game design.


Here's a recent post from the Society for Science about YGDA!


Currently, our team of ~10 is working on “Farmicide” a multiplayer survival game in which two farmers compete for eternal crop domination.

Hobbyist | Social Impact

I started my acting career at the age of seven as a minor actor for Sight & Sound Theaters, learning to act, dance, sing, and handle animals. Across 8 productions, 1 TV Spot (Voiceover), and 1 on-screen Fathom Event, the Sight & Sound cast and crew became more than professional peers but a second family. Moving from the theater was one of the hardest experiences of my life, but now, I use my ability as a communicator to solve community problems and inspire the next generation of change-makers!

Hobbyist | Competitive Problem Solving

"Can a square be split into an odd number of triangles with equal area?" — Fred Richman

As co-captain of Varsity Math Team, my mission is not to lead one of the most successful US math teams but to help more people grasp the beauty of such questions. When I compete at a national contest, I'm a collector, obsessing over intriguing ideas, like a child scouring for seashells on a beach. I'm an artist, channeling my creativity into problems that feed eager, young mathletes on in-person olympiads. Whether it's proof-based mathematics, theoretical computer science algorithms, or physics thought experiments, I've fallen in love with problem solving.

Hobbyist | Distance Running

I started distance running to condition myself for the spring soccer season, but running has become as much of a social activity as an athletic one. While the post-workout runner's high of endorphins coursing through my veins is liberating, friendly games of tag or ice hockey on the frozen lake in the winter are just as exciting. The calming breeze on a long run clears both the sweat on my chest and the stress in my mind, but I most enjoy spending time with others during physical exertion.

Cross Country


I started XC in freshman year with a 22m 5k time. Three years later, I have a PR of 18:58 and can't wait to push myself even further!


I am proud to have represented TJHSST at multiple invitational meets and XC districts. Check out my profile on MileStat!

Track & Field


Indoor track districts competitor in the 1000m with a PR of 3:01.75! Coach also makes me run the 3200m which is really exhausting. 🏃‍♂️💨


During outdoor track, I broke 5:10 in the 1600m, and in freshman year, I made regionals in the 55m!
