Before that, he completed his BS degree in Mechanical Engineering at Bangladesh University of Engineering and Technology( BUET) in 2003. He obtained Professional Engineering license (PE) in 2014.
My Courses
MECH 4780- Design and Selection of HVAC System
This course covers detailed calculation of Heating and cooling systems, unit sizing and Ducting. Both Hand Calculation and software-based calculations will be covered in this course. Variabilities in the components of HAVC systems will also be covered. A demonstration will be provided on how those variations address the HVAC demands of residential and commercial envelopes. Students will have the opportunity to engage with and learn to operate Environmental Control Technology equipment, including control valves, pumps, and fans, during the lab sessions of the MECH 4780 course. Participants in this course will have opportunities to take certification exams in ASHRAE CHD.
Strength of Materials II
This course handles the basic concepts of thermal energy conversion and transfer. Dual use of S.I. and English engineering units are employed in order to understand gas laws, fluid processes, first and second laws of thermodynamics, theoretical cycles, internal combustion engines, gas turbines and jet engines, refrigeration cycles and the heat pump. The course covers practical aspects of Heat transfer through radiation, conduction and convection.

Composite and Bio Materials Lab
The objective of the lab is to develop advanced materials and process for high temperature solutions and Bio-Engineering applications. Using the innovative materials the lab focuses on improving the structural integrity of high temperature composites. Alongside, the lab is focused on evaluating interactions between the material combinations in the human body under various abnormal situation including head trauma. Currently my Lab is equipped with – Mechanical testing including Compression, tensile, Flexure and DMA. Also my lab is equipped with Electro-spinnning, Hot Press, Climate control Furnace, Optical Microscopy, 3D Printers and CNC. In addition, The lab also have capabilities in and external collaboration with SEM, XRD, DSC, TGA and NMR.
Display of my Product
Study of Phase Separation and Crystallization of Li-Si glass
This project concerns the phase separation and crystallization behavior of Lithium Di-silicate glass at a little over stoichiometric Si:Li Ratio (2.33). The objective of this research is to improve the mechanical strength and thermal stability of Lithium- Silicate glass system.
