Avimukh.com
Avimukh is a Bengali website for poets, writers, and bloggers. I designed its backend in Ruby on Rails framework. The web-app is hosted on Heroku.
The site is under serious construction! Please watch your step.

I knew you would visit my homepage one day! The site showcases my research
and software projects, ocassional tutorials, sporadic rants, and more. From
time to time, I get intrigued by different topics in math, coding, data
science, software, history, politics, music, and subjects that no one else
on Earth would care about. As soon as I start to dig in and things suddenly
get little beyond my apprehension, posting here helps me wrap my head around
it. This collection—if nothing else—helps me now to organize my
thoughts, and would help me one day realize how I wasted my days!
As the odds of landing on my site at random are one in 1.8 billion (see), you are
probably looking for something, and Google just got too generous.
Nonetheless, feel free to browse, find mistakes, and leave your valuable
comments.
Here is a quick link to my résumé.

| Where to Find Me
| Research
My research primarily revolves around the interface of mathematics and computer science. More specifically, my research is motivated by theoretical problems arising in topological data analysis (TDA), computational and applied algebraic topology, and computational geometry. I am also interested to solve real-life problems using tools from algebraic topology and geometry. My research interest also extends to applying TDA to other fields of science and developing computational libraries and software.

| Talks and Presentations
I had been a big fan of Beamer for
quite some time. Who wouldn't be when it comes to presenting slides full of
math symbols? Although the math looked fancy and the audience was happy, the
$\LaTeX$-based framework had
also disappointed me quite often. I found the framework too restrictive to
customize; my slides looked exactly like others'!
Features, that were lacking in Beamer during the time I broke up with
it, were shining in
RevealJS. Since then, I have been
using it, customizing it, and relishing it.

Shape Comparison and Gromov-Hausdorff Distance
Tulane University |
January 21, 2020
The Gromov-Hausdorff distance between any two metric spaces was first introduced by M. Gromov in the context of Riemannian manifolds. This distance measure has recently received an increasing attention from researchers in the field of topological data analysis. In applications, shapes are modeled as abstract metric spaces, and the Gromov-Hausdorff distance has been shown to provide a robust and natural framework for shape comparison. In this talk, we will introduce the notion and address the difficulties in computing the distance between two Euclidean point-clouds. In the light of our recent findings, we will also describe an O(n log n)-time approximation algorithm for Gromov-Hausdorff distance on the real line with an approximation factor of $5/4$.

Shape Reconstruction
Tulane University |
August 08, 2019
Most of the modern technologies at our service rely on 'shapes' in some way or other. Be it the Google Maps showing you the fastest route to your destination eluding a crash or the 3D printer on your desk creating an exact replica of a relic; shapes are being repeatedly sampled, reconstructed, and compared by intelligent machines. With the advent of modern sampling technologies, shape reconstruction and comparison techniques have matured profoundly over the last decade.

| Software and Computing
I am a coding hobbyist. I enjoy solving online coding challenges. Although Java is my favorite programming language, I also code in JavaScript, Ruby. I develop softwares both for academia and industry. Some of them are listed here.
