Data Scientist, MSc Data Science, University of Nottingham

Predictive modelling in Python and R, statistical machine learning, reproducible analysis

I am a data scientist with an MSc in Data Science from the University of Nottingham and a first degree in mathematics from the University of Delhi. I build predictive models, test them with paired experiments and nested validation, and explain the results to people who are not statisticians.

For my dissertation I implemented Mondrian forests from scratch in Python. In summer 2026 I delivered a live data product for a San Francisco start-up in two weeks.

Projects

World Cup Sleep Index

06/2026 – 07/2026

Hermai.ai, client project

Python, GitHub ActionsLive siteCode

A live site that shows how much sleep each of the 48 fanbases loses to the kick-off times of the 2026 World Cup. I cleaned the 104-match fixture data, mapped every fanbase to its home time zone and set up a six-hourly rebuild that halts publication if any fixture fails its checks.

Contaminated Chemical Detection

Spring 2026

Statistical Machine Learning, group project (Distinction)

A group project that predicted the impurity type and percentage of 100 chemical samples. Our R pipeline placed first of three groups on the prediction leaderboard. Replacing a random forest with one linear model per impurity type reduced the error score by 33%.

R

QMC Hospital Database

2025

Databases coursework (Distinction)

A hospital records system on MariaDB. I extended a 7-table schema to 9 tables, joined each patient’s admissions, tests and examinations into one searchable view, and added an audit log of 8 kinds of user action.

SQL, PHP

British Airways Reviews and Booking Signals

2025

Data science project

Sentiment scoring and a 10-topic model on 2,000 Skytrax reviews put cancellations and refunds at 20.7% of all reviews. Tree-based models on 50,000 bookings ranked purchase lead time, route and flight hour as the three strongest signals.

Python

East Midlands House-Price Forecasting

2025 – 2026

Time Series and Forecasting

Six-month forecasts with 80% and 95% prediction intervals from two seasonal ARIMA models fitted to ten years of monthly data, with a one-page summary written for non-technical readers.

R

Research

My research interests are statistical machine learning, computational statistics and the behaviour of methods when the training data are contaminated.

Mondrian Forests under Limited and Contaminated Data

2026

MSc dissertation, marked at 80%

An empirical study of Mondrian forests against CART and random forests under changes in sample size, label noise and feature-space outliers. I implemented the method from the algorithms of Lakshminarayanan, Roy and Teh (2014) and ran every comparison on paired seeds. Choosing the lifetime by validation reduced excess error by a factor of 7 to 23.

Road-Collision Severity Prediction

Spring 2026

Research paper, Data Science with Machine Learning

Four classifiers compared on 29,628 police collision records from the East Midlands with nested cross-validation (10 outer folds, 3 inner). Random forest had the highest macro-F1 (0.555 ± 0.014) and came first in all ten outer folds. The lecturer chose the analysis as a teaching example for the 2026–27 cohort.

Spectral Clustering in Machine Learning

Autumn 2025

Group report (team of four), Statistical Machine Learning

I wrote the mathematical sections, from the graph Laplacian to the relaxations of RatioCut and the normalised cut as eigenvalue problems, with every step worked on an 11-node example graph. I also wrote the discussion and most of the conclusion.

Experience

Student Consultant (Data Analyst)

06/2026 – 07/2026

Hermai.ai, University of Nottingham micro-placement

Delivered the World Cup Sleep Index for the co-founder in two weeks, as the analyst on that project in a seven-person team.

Data Science and Business Analytics Intern

05/2024 – 07/2024

The Sparks Foundation

Analysed monthly sales trends and compared performance across stores and product categories using SQL JOINs, CTEs and aggregate functions. Cleaned and reconciled sales and product records in Excel using Power Query, XLOOKUP and PivotTables. Developed interactive Power BI dashboards with DAX measures and slicers to track sales performance and consolidate monthly reports.
