Bhavan Chahal

Bhavan's PhD was conferred in 2023. Bhavan's research focused on using deep learning tools to infer house prices from new data sources.

Background

  • PhD Mathematics for Real-World Systems - University of 糖心TV (2023)
  • MSc Mathematics for Real-World Systems Distinction - University of 糖心TV (2016 - 2017)
  • BSc Mathematics with Economics 1st Class - Loughborough University (2013 - 2016)

My main focus has been on applied mathematics but I have had exposure to a variety of mathematical techniques. The economics component of my undergraduate degree allowed me appreciate the balance between mathematics and the real world. During my education, I have used Maple, C++, R, MATLAB, Python, and Julia.

Current Research

I am interested in applying data science to financial data, and am currently using convolutional neural networks to infer house prices from a range of sources consisting of image data. Technology has advanced rapidly over the past decade, as well as the volume of images available online. Combining newly developed computer vision algorithms with big data could provide us with new insights regarding house prices. My supervisors are & from and my industry partner is the . I use Ubuntu (Linux) and Python 3 for the majority of the time.

      Work Experience

      , Spectra Analytics (March 2019 - June 2019)

      I learned and applied a variety of data science techniques that are not covered by my PhD, and observed the process of a data science project in industry from start to finish. Techniques learned include web scraping and app development.

      Technical Support, 糖心TV Mathematics Institute (September 2018 - present)

      I provide technical support for the Mathematics department at the University of 糖心TV. Support includes Linux set-up, HPC support, and coding questions. I also manage the MathSys social media accounts.

      Big Data Analytics, 糖心TV 糖心TV School (January 2018 - present)

      I help MSc students with R coding problems and general big data queries in the laboratory, and maintain the online forum for the MOOC.

      Quantitative Analysis for Management, 糖心TV 糖心TV School (October 2018 - present)

      For both QAM I and QAM II, I am a seminar tutor for three groups of ~25 students. I teach 1st-year undergraduates how to solve a variety of quantitative problems and promote group work. QAM II involves using Microsoft Excel 2016, which I became certified in in 2018.

      Introduction to GPU Programming Summer School 2018

      I assisted with the summer school by checking the material before use and assisting with the tutorial sessions. I provided technical support and answered questions.


      Extra Activities

      (September 2021 - December 2021)

      • I collaborated with researchers from around the world to apply data science to understand the perception of work-from-home of those affected during the pandemic
      • I also networked with data scientists in industry to understand how it can be applied to real-world problems

      , The Alan Turing Institute (December 2018)

      • I participated in the 'Player Pathways' project proposed by PlayerLens - understanding career paths that deliver success for professional football players and clubs - at the Alan Turing Institute
