Research

Since my third year of undergraduate studies, I have been actively engaged in research across several domains, including molecular dynamics, machine learning, control systems, and mechatronics. A defining aspect of my work has been the integration of deep learning techniques into mechanical engineering applications, an area with significant untapped potential. My research is focused on pioneering the use of these advanced methodologies in fields where they have yet to be fully explored.

Research Experience

Research Assistantship

Department of Mechanical Engineering, BUET

Under the Guidance of Dr. Shahereen Chowdhury, Assistant Professor, Dept. of Mechanical Engineering, BUET

My current research involves the application of 3D convolutional neural networks in predicting material properties at atomistic scale.

SUPREME 2024 - Summer Program

CIMPI LAB, Washington State University

Under the Guidance of Dr. Satyajit Mojumder, Assistant Professor, Washington State University

Participated in a summer research mentorship program under the supervision of Dr. Satyajit Mojumder, Assistant Professor at Washington State University, where my task was developing a reinforcement learning-based control system for the laser powder bed fusion process while also writing an analytical solver in Python.

Undergraduate Thesis

Implementation of Hybrid Conv1D-LSTM model in predicting the crystal structure evolution of Aluminum at different cooling rates.

Supervisor: Dr. Shahereen Chowdhury, Assistant Professor, Dept. of Mechanical Engineering, BUET

We have been working on training and tuning multiple deep learning models to predict the non-linear behavior in evolution of crystal structures in Aluminum at different cooling rates. Additionally, I have devised and implemented an automated procedure for conducting a large number of molecular dynamics simulations, extracting analysis data from OVITO, and assembling a comprehensive dataset.

Laser Powder Bed Fusion

Currently working on an atomistic simulation of Laser Powder Bed Fusion of Invar 36 to examine its mechanical properties at different laser parameters i.e. laser power and speed.

Research in the field of AI

Trained and optimized an image classifier applying explainable AI to assist vision-impaired users in identifying rapid test kit results via mobile application.
