I am an applied research scientist interested in challenging problems that can have an impact. My primary research areas include applied natural language processing and artificial intelligence.
The following sections should help you understand my work and my experiences.
Welcome to my world.
The following includes my research that has been published as my thesis and in peer-reviewed conferences and journals.

Except having the honor of publications, I have also been featured in a few university briefs.
Most of the code and documentation is available on my GitHub.
- Apple’s COVID-19 Mobility Data for India: I spent a couple days looking at and playing with the mobility data Apple decided to start publishing. I thought it had some interesting trends (specifically for different cities) and I pondered over what was causing some of the specific changes.
- Integrating preventive care guidelines & EHR to provide better healthcare: My MS thesis is about improving preventive healthcare recommendations by using natural language processing. Through this project, I have succeeded in providing personalized preventive care recommendations to patients by analyzing patient EHR data and USPSTF Preventive Care guidelines.
- Prediction model for water demand in Central Indiana for Citizens Energy Group: I designed a parallel RNN algorithm to predict daily and monthly average water demand with a very high accuracy. My model achieved an average error rate of 1.69% for daily predictions and 2.29% for monthly predictions.
- Disease-based biomedical document search and retrieval using Word2Vec: I developed an algorithm that uses disease ontology for biomedical document search and retrieval. With an innovative concept weighing scheme for biomedical documents, I have overcome the problem of semantically equivalent biomedical concepts being represented using heterogeneous lexicons.
- Navigation tool to compute the best route based on road safety: This project is based on artificial neural networks and uses information of past fatal accidents that have occurred in USA to predict future accidents and compare various route options from location A to location B.
- A Home Automation and Internet of Things Solution for Indian Homes: In this project, a home automation system focusing on solving specific Indian home problems (automated passageway and room lights, keyless door lock and LPG cooking gas leakage detection and ordering system) was created.
- Android app to log GPS and Accelerometer data to local storage and server: An Android app that periodically collects data from the GPS and accelerometer sensors and stores it on a local buffer and if enabled, a web server.
- Android navigation app that computes the safest route for travel: An extension of the previous navigation tool app that computes the safest route for travel based on time of journey, fatality rate prediction and weather conditions.
- Simulation of various Ad-Hoc Routing Protocols using NS-3: Simulated various Mobile Ad-Hoc Networks for routing protocols like AODV, DSDV, DSR, OLSR, GPSR and Bird Flocking Routing Algorithm (BFA) using Network Simulator-3.
- Smart Socket: A 3-pin socket that doesn’t enable electricity supply to the appliance connected until the plug is inserted entirely, thus helping in preventing short circuits, excessive draw current and electric shocks for the user and provides protection from surge voltage, under-voltage and ground leakage protection.
- Sanjay Shah Seminar website: A couple of years back, when dad asked me if I would develop his website a few years ago, I took up the challenge. While I do not maintain it anymore, I created it in early 2011 and maintained it through the first half of 2016.
- Bhavin Shah’s website: I also help a dear friend, my mentor (and now a published author!) with creating and maintaining his website.
- Not Just The Talks: I realized I wasn’t fine with the way things were in my country and in the society around me. This was my attempt at making a difference through my writing. It has been quite sometime since I last wrote on there.
While my real life handwriting is often described as scribble, I like to believe these are more legible. Over the course of the years, I have written quite a lot. Read it. I hope you find something you like.
- (micro)blog: I recently started posting short snippets of things I want to say out here. This fills the space between Twitter and my blog. It also serves as a place for me to post things I would’ve earlier posted on Tumblr, I Talk Tech or Unwind blogs. More often than not, this is where you’ll find my most recent posts.
- Blog: That blog where I talk about everything from my current affairs to politics to human behavior.
- Not Just The Talks: My posts on an (now defunct) initiative close to my heart.
