Arafat Shaon

An enthusiast in computational science and mathematics with experience in numerical analysis, high-performance scientific computing, and data visualization. I have developed these skills through research on differential equations and diffusion processes using implicit and explicit Runge-Kutta, Euler, and ADI methods. That's how I obtained expertise in MATLAB, Python, C++, Bash, Linux, SSH, and computing cluster workflows for large-scale computation and parallel processing.

Also, I practiced research documentation, technical problem-solving, and data-driven analysis amid academic and operational roles.

Research Assistant at University of Massachusetts Dartmouth (2024-05 – Present)

Supervised by Prof. Dr. Sigal Gottlieb. Obtained experience as a research assistant by doing research on Computationally and Energy Efficient Mixed Precision and Mixed-model Numerical Methods.

• I did numerical analysis of the Van der Pol equation using SDIRK and explicit/implicit Euler schemes implemented in MATLAB to evaluate accuracy and stability across parameter ranges for developed and compared solvers to identify robust methods for stiff and non-stiff regimes.
• In this process, I found the approximate stability region of time variance for the linear and nonlinear PDEs for the wave equation and heat equation.

Heat Simulation Researcher at University of Massachusetts Dartmouth (2025-03 – Present)

Heat Simulation on a 3D Graph Representing the Ocean by Using the ADI Method. Mentored by Prof. Scott Field.

• Performed 3D ocean heat simulations using the Alternating Direction Implicit (ADI) method to model diffusion processes on structured grids.
• Designed and implemented a hybrid parallelization approach for large-scale computations, working with arrays of 100,000,000 and 300,000,000 elements to optimize memory usage and parallel programming on HPsC systems.
• The research concluded in choosing hybrid parallelization in terms of big data arras.

Teaching Assistant at University of Massachusetts Dartmouth (2024-01 – 2024-05)

Advanced Mathematical Stats (MTH 522). Supervised by Prof. Gary Davis.

• Helping students learn and understand statistics along with Python programming and guiding them to keep up with the lessons.
• Grading students' projects through the LMS named Canva.

Teaching Assistant at University of Massachusetts Dartmouth (2024-01 – 2024-05)

Calculus II (MTH 152-02). Supervised by Prof. Melvyn Huff.

• Helping students learn and understand pre-calculus and the computing methods in differentiation and integration.
• Grading students' projects through the LMS named Canva.

Math Instructor and Executive Manager at Mojaru Education Technologies Limited (2022-07 – 2023-10)

Taught 13 batches of K-12 learners as a math instructor, where each batch had 20 students. I gained experience by maintaining responsibilities such as

• Developing Olympic-based math slides to teach students via Zoom.
• Leading instructors as a program manager in course and curriculum development, teaching method development, student record management, and compliance management.
• As an achievement of my professional period at Mojaru, I successfully led the organization in achieving STEM.org authentication in 2023

Head of Operations and Product Developer at Staff Asia (2021-03 – 2022-05)

Worked as an operations manager of 3 BPO brands at Reed.co, containing more than 4500 BPO products. My priorities were managing operations such as

• product development
• sales data analysis
• marketing management
• sales strategy planning
• compliance management
