Research

My research focuses on breaking down complex systems into simple, manageable parts and mechanisms that can be analysed and evaluated individually. I aim to apply this approach to real-world problems by simplifying intricate ideas and concepts into structures that can be better understood and applied.

Ideas in Progress

Questions, patterns, and ideas I'm currently exploring across mathematics and economics.

01

Length-to-Diagonal Ratio

Geometry · Higher Dimensions · Patterns

A square with side length n has a diagonal of n√2, while a cube has a longest diagonal of n√3. In 4D, this becomes 2n. What happens in higher dimensions — and what about rectangles, cuboids, and other shapes?

02

Factorial Analysis of n×n×n Rubik's Cubes

Combinatorics · Permutations · Functions

How does the number of possible combinations grow as the size of a Rubik's Cube increases? Can this factorial behaviour be analysed and extrapolated as a function or graph?

03

Pareto's Law / 80–20 Rule

Inequality · Market Conditions · Rationality

In a free-market economy, does disproportionality continue to increase without government intervention because of an intangible mechanism?

04

Powers of 11 and Pascal's Triangle

Number Theory · Algebra · Combinatorics

When base 11 is raised to different powers, it starts to show the patterns of Pascal's Triangle: 11, 121, 1331, …, corresponding to a+b, (a+b)², (a+b)³, ….

05

Poker Outcomes Through Game Theory

Probability · Game Theory · Rational Decision-Making

Can the possible outcomes in poker be predicted using probability and player choices, assuming rational decision-making, and can game theory be used to find the optimal bets?

01

A Relationship Between π and e

Number Theory · Irrational Numbers · Algorithms

π⁴ + π⁵ ≈ e⁶. Can I produce an algorithm to find a direct or even closer approximation between these two irrational numbers?

02

The Ending Digits of Powers of 5

Number Theory · Modular Arithmetic · Patterns

How do the ending digits of powers of 5 evolve as the exponent increases? The values seem to repeat — but at what frequency, and can a formula be derived from this?

03

Recurring 9s and Countable Infinity

Number Theory · Infinity · Set Theory

Since 0.999… = 1, could the idea of recurring 9s also be used to think about countable infinity? If infinity can be approached but never reached, is there a similar relationship between recurring numbers and infinity?

04

Modular Arithmetic and Digit Patterns

Number Theory · Modular Arithmetic · Patterns

For any n-digit number, there is at least one digit divisible by n, or a combination of two or more digits whose sum is divisible by n. Can similar modular arithmetic ideas be applied to multiplication, subtraction, other operations, or different patterns?

05

Rethinking the Shape of Diminishing Marginal Utility

Behavioural Economics · Mathematical Modeling · Real-World Context

Theoretically, diminishing marginal utility is often shown as a smooth decline. But in real choices, could the decline be uneven — sometimes steep, sometimes gentle, or even shifted by certain units because of behavioural factors and individual choices?

Interactive Explorations

Exemplar Models & Projects

Interactive models and experiments exploring mathematical and economic ideas. Each project explains the underlying idea, how the model works, and provides ways to explore it through examples and interaction.

Mathematics

Visual and interactive explorations of mathematical patterns, structures, and curiosities.

Modular Arithmetic

Origin

This is a "modular addition table" which is based on the branch of mathematics called Number Theory, specifically Modular Arithmetic. It's based on the principle that if the sum of non-negative integers exceeds or falls exactly at the agreed number n, it will loop back. That is: for whole numbers x, y (0, 1, 2, 3, ...), if x + y ≥ n, where n is a positive integer and the agreed modulus, the possible values you can get for the sum x + y can correspond to set z: {0, 1, 2, 3, ..., n − 2, n − 1}. With that being said, since the sum will always result in a non-negative value, the sum can be represented as n × m + q, where m, q are whole numbers and q is an element in set z.

How it works

Choose your "n" value, ideally between 1–10 for simplicity, and say n = 5. A table will be generated with the headers of rows and columns being: 0, 1, 2, 3, 4. For example, according to modular arithmetic: 0 + 1 = 1, 3 + 2 = 0 (because 3 + 2 ≥ 5, so it can be represented as 5 × 1 + 0, thus we get zero). Similarly, 4 + 4 = 3 (4 + 4 ≥ 5 and 5 × 1 + 3); To simplify this, when n = 5, calculate the sum of two numbers in algebra, then repeatedly subtract n until the new value is less than n but still non-negative: 4 + 4 = 8, and 8 − 5 = 3, and 0 ≤ 3 < 5, so in modular arithmetic, 4 + 4 = 3.

Explore

Please feel free to explore this feature, and I highly suggest observing any noticeable and recurring trends or patterns. You can try the same steps but with multiplication on your own if you are really fascinated by this concept!

Economics

Interactive models and experiments exploring economic ideas, relationships, and systems.

Supply & Demand

Origin

Supply and demand is a fundamental economic model used to understand how prices and quantities are determined in a market. It describes the relationship between what consumers are willing to buy and what producers are willing to sell.

How it works

As price increases, quantity demanded generally decreases while quantity supplied increases. The point where the two curves meet is the market equilibrium.

Explore

Start the model and change the market price. Observe how quantity demanded and quantity supplied respond, and use the difference between them to identify a surplus or shortage.

Initiatives

01

Student Council Member & Valiant Vikings House Captain

As a member of the Learner Council, I worked on day-to-day student concerns and issues, upcoming school events, social-change initiatives, and student responsibilities across the school. I contributed to planning and supporting student-facing events, helped represent student perspectives, and worked alongside other council members to turn ideas into initiatives that could benefit the wider school community. As Valiant Vikings House Captain, I took responsibility for coordinating and motivating my house, with a focus on both performance and teamwork. I planned activities by understanding my teammates' strengths and placing them where they could contribute most effectively, while also making sure everyone was comfortable and happy with their choices. I regularly checked in with team members, followed their progress, and helped coordinate participation across activities. We ultimately won the House Trophy that year, completing a hat-trick of consecutive victories.

02

Founding President — STEM Club

Co-founded and served as the founding president of JBCN's first STEM Club. The club focused on hands-on learning through practical experiments rather than purely theory-based activities, with the aim of fostering curiosity, critical thinking, and problem-solving. I helped organise guest lectures, university visits, and student-led workshops, giving members opportunities to learn from professionals as well as from one another.

  • Spaghetti Tower-Building Challenge
  • Vedic Mathematics
  • Design a Bridge
  • Guest Lecture on Cloud Computing
  • Student Lecture on Reverse Engineering

03

Bake Sale — Shraddha Foundation

Along with Arhaan Lightwalla, Shivaan Sharma, and Vir Gangoly, I organised a bake sale at school to raise funds for the Shraddha Foundation, a shelter for cancer patients and survivors in Chembur. The idea was to use a school event to create a direct contribution to a local cause. We proposed holding the bake sale during a Quarter 2 PRD, planning to sell simple, non-spillable, room-temperature items such as muffins, cupcakes, bagels, brownies, and cookies. The initiative eventually took place during a parent-teacher meeting on the school campus, allowing us to reach a much wider section of the school community. We baked and prepared items ourselves while also receiving contributions from other students, turning the sale into a broader student-led effort. All proceeds from the bake sale went to charity, supporting the Shraddha Foundation and helping contribute towards a Christmas celebration for the people it serves, including food and gifts.

Created Teen Health Decoded, a platform focused on making healthy eating and lifestyle information more accessible and relevant to teenagers. The idea grew from my interest in the relationship between food, health, behaviour, and the environments in which young people make everyday choices. This became particularly interesting as I explored the wider policy landscape around food in schools. FSSAI's school-food regulations restrict the sale of foods high in fat, salt, and sugar (HFSS) to school children in school canteens, messes, and hostel kitchens, as well as within 50 metres of school gates. The framework also encourages schools to promote safe and balanced diets and healthier food environments. Rather than viewing healthy eating simply as an individual responsibility, I became interested in how schools, food environments, policy, and education can collectively shape the choices available to teenagers. Teen Health Decoded is my way of contributing to that conversation by sharing practical, accessible ideas around food and healthier lifestyles through a platform created specifically with teenagers in mind.
