Heat transfer has been my focus from the start — a Refrigeration & Air-Conditioning diploma (class rank 2), a B.Eng. in Mechanical Design at JUST (class rank 1, top 1%), and an M.Eng. at Laurentian (top 2%) have built a foundation spanning vapour-compression systems, ANSYS/Abaqus structural and thermal FEM, SolidWorks Simulation, and MATLAB thermal modelling.
My graduate project on lithium-ion battery thermal management and a review paper on hybrid TEC + vapour-compression sub-cooling architectures put thermoelectric cooling at the centre of my academic work. I now want to deepen that into doctoral research — specifically the mechanical robustness, module fabrication, and system-level integration of magnesium-based thermoelectric coolers for solid-state refrigeration.
Four academic credentials across Bangladesh, China, and Canada — each building depth in thermal-mechanical engineering.

Modelled heat generation in lithium-ion packs and compared air, liquid, PCM, and thermoelectric cooling strategies using MATLAB and ANSYS thermal simulations. This M.Eng. research project at Laurentian University formed the basis of the graduate capstone for the Engineering Science programme.
Publication
Comprehensive literature review of hybrid TEC-vapour-compression architectures. Analysed COP trade-offs, ZT material selection (Bi₂Te₃, Mg₂Si, Mg₃Sb₂), and Peltier sub-cooling integration strategies for precision thermal management applications.
Built Abaqus finite element models of structural components (bars, beams, frames) and verified stress and displacement fields against closed-form analytical solutions. Achieved agreement within 0.5% on benchmark cases.
Static and modal ANSYS FEA on bars, beams, plates and more complex geometries; validated against closed-form solutions. Includes parametric studies on mesh density and element type selection.
Vibration-signature analysis on rolling-element bearings to detect early-stage faults including inner-race, outer-race, and ball defects. Methodology transferable to TE module reliability monitoring.
Design
Designed a drop-hammer impact testbed with automated release mechanism and PLC-based data acquisition, built to study crashworthiness and energy absorption of honeycomb composite materials. Full 2D/3D SolidWorks package delivered.
Complete injection mould design for a two-plate mine cable hook, including runner system, gate design, cooling channel layout, and ejector system. Production-ready SolidWorks drawings with GD&T annotations.
Group project: Structural analysis and design of sill-mat systems used in underground mine backfill operations, ensuring stability under geostatic loading. Included material selection and factor-of-safety calculations.
Report
Comprehensive hazard identification, risk assessment, analysis, management and recommendations for mitigating workplace health and safety risks associated with underground mining operations.
Literature review seminar on wastewater treatment techniques with a focus on evaluating the effectiveness of the adsorption method for removing heavy metals and organic contaminants from industrial effluent.
Invented a portable thermoelectric water chiller for the BBPI Annual Science Fair (2016). Independently discovered the Peltier effect and built a TEC-based device that cooled 500 mL from 28°C to 8°C in under 8 minutes — 55% faster than a household refrigerator.
Awarded on academic merit and to students who lost employment because of the Russia–Ukraine conflict (remote role at AMACOA GmbH, Germany).
Granted for outstanding academic performance and substantial volunteer contribution to the university community at JUST.
Annual award based on academic ranking across the entire Engineering faculty.
Merit-based recognition during admission — awarded to the highest-ranking incoming students.
Skills & Training Enhancement Project: competitive talent-based award for outstanding diploma-level engineering students in Bangladesh.
