Arindam Kumar Paul (Bengali: অরিন্দম কুমার পাল) (19 September 1995 – 27 April 2024) was an early-stage researcher   in Applied Mathematics from Bangladesh. Besides being a mathematician, he was also a computer programmer, a columnist and a Science & Technology activist   in Bangladesh.

Arindam, in his short lifetime, published several research articles. Through his research works, he contributed in the area of Applied Dynamical Systems, Mathematical Modelling, Optimal Control, Data Science and Machine Learning. Moreover, he authored two books Algorithm Design and Mathemathematical Dictionary of Machine Learning (both written in Bengali language), which are very famous among the students of Bangladesh.

Engagement in diverse fields
Arindam, in his early life, solved more than 4000 problems in all the categories of mathematics on the world's largest problem-solving website Brilliant Organization. He maintained efficiency in solving top difficulty level problems for more than six months continuously in all the categories of mathematics and computer science. He was honored as the Top Problem Contributor in the years 2016 and 2017 by the Brilliant Community for contributing diverse problems and essential wikis on various mathematical concepts. Basically, he was a skilled mathematician and a very passionate person who used to think in mathematical ways. He was the person who wrote the first Python Programming tutorial in Bengali covering basic to advanced levels of concepts consisting of 29 series in the year 2013. The title was "মজার ও সহজ পাইথন প্রোগ্রামিং".

In 2016, he started his journey in solving multidisciplinary problems with mathematics and worked in diverse fields of mathematics and data science. In addition to that, he was highly skilled and experienced in Python, MATLAB, JavaScript, R and some other programming languages. He was capable of solving multidisciplinary and totally unique types of complex problems by combining his knowledge of mathematical science and programming skills.

Since 2018 to his death, he had trained a number of students and professionals by helping them in Applied Mathematics, Machine Learning, Artificial Intelligence, Data Science, Digital Signal & Image Processing, Applied Statistics and Probability. He also guided them in completing their scientific and commercial projects.

Adarsha, one of the best Publisher in Bangladesh invited him to write a book on algorithms in 2017 and they published the book entitled অ্যালগরিদম ডিজাইন at Book Fair of 2018 and মেশিন লানিংয়ের গাণিতিক অভিধান at Book Fair of  2021. Both of the books are available in almost all stores in Bangladesh and abroad including Rokomari, Amazon and Google Books.

Arindam had published more than 15 research articles internationally in the area of Mathematical Modelling and Analysis, Dynamic Optimization, Machine Learning and Signal/Image processing.
