STUDENT / RESEARCH & WRITING

Nalin Aggarwal.

I like making things
and figuring them out.

I’m a student in Navi Mumbai. I build software, study how decisions work, and write about the questions that stay with me.

PHYSICS ↔ ECONOMICS ↔ PEOPLERESEARCH, WRITING & A BIT ABOUT ME
THREE PROJECTS, UP CLOSEALL EIGHT PROJECTS ↗

From the
working files.

A simulation, a team prototype and an operations-research study. Here’s what I contributed and what the work showed.

From the confirmation studyRESEARCH
Original lensing results comparing batch success, retained systems and computation cost.VIEW FULL SIZE ↗
Original figure. Four policies each reached 60/64 successful batches; computation and retention differed.
COMPUTATIONAL ASTRONOMY · Conditional simulation study

The cost of certainty

I set up the simulation, separated calibration from confirmation, and compared ways to allocate computation.

WHAT HAPPENEDThe cheaper control matched the observed success count. More computation did not establish an advantage in this conditional study.

Dashboard capture using sample data. The readings shown are for interface testing, not field measurements.

Beyond the sensor

I managed the project with a team of juniors at my school, contributed to hardware and software, and worked on the finances, pitch and presentation.

WHAT HAPPENEDThe software makes readings traceable and missing data explicit. Independent field validation remains open.

From the validation resultsRESEARCH
Original freight-study validation figure comparing test-day failure fractions across five LaDe cities and Olist.VIEW FULL SIZE ↗
Original manuscript figure. The LaDe pickup test met the criterion in three of five cities; the declared target was four.
OPERATIONS RESEARCH · Research manuscript · ongoing validation

Before demand arrives

I formulated the capacity-and-information problem, implemented the solver comparisons and wrote the research manuscript.

WHAT HAPPENEDNo algorithm led in every regime. Three of five cities passed a validation criterion that required four.

A SMALL EXPERIMENT / ABOUT 30 SECONDSGUESS THE RESULT, THEN TAKE A LOOK.
THE ALLOCATION STUDY

Is more computing
worth it?

Four allocation policies and a cheaper, fixed control faced the same 64 confirmation batches. Would spending more computation improve the result?

The question behind the study: how much computation does a useful mass estimate need? Illustration only · not the study’s solver.
THREE PIECES TO START WITHALL WRITING ↗

Why I
wrote these.

Different subjects, each starting with something I wanted to understand.

ALSO ON MY DESK

Essays on Alexandria and moral motives, plus Ticker Heartbeats, a novel in progress.

Essays & fiction ↗
AWAY FROM THE PROJECTS

There’s a person
behind the work.

Guitar practice, a novel I keep revising, and the people I’ve worked with. There’s more to me than the project list.
