Data Science:

 

In the realm of data science, my journey has been a thrilling exploration into the boundless possibilities of artificial intelligence and machine learning. Harnessing the power of data, I've delved into deciphering intricate patterns, constructing predictive models, and crafting algorithms that not only unravel complex insights but also pave the way for informed decision-making. From wrangling diverse datasets to fine-tuning models for optimal performance, my experience has been a fusion of creativity and precision, navigating through the nuances of algorithms to unearth actionable solutions. Whether it's employing regression techniques for predictive analytics or diving into the depths of neural networks for deep learning, the quest to extract meaningful information from data has been an exhilarating expedition, fueling my passion to innovate and drive transformative change through the lens of data-driven insights.

 

Concrete Materials:

 

From the very beginning of my graduate study at Boise State University (BSU) I have been working in the MicroMechanics and Smart Infrastructure group of Civil Engineering department. My major concern is to develop damage model for concrete materials to predict service life with the progression of time. Concrete is frequently used as a construction material and is of major focus in the field of Civil Engineering. Throughout my research work in this group I have gained experience to work on image processing to generate concrete meso-scale geometry based on the real cement to aggregate ratio. I have learned to come up with governing equations set and couple them together for multiphysics modeling based on the chemo-physical-mechanical phenomena oof concrete structure. I have worked on investigating the concrete degradation under Alkali Silica Reaction (ASR) and developed finite element model that has potential to quantify damage in concrete meso-structure under service load. My expertise also includes freeze-thaw cycle and phase change modeling of concrete materials.

Construction Materials Lab:

​

I have gained expertise over different lab testing as  a part of my Teaching Assistant job in the Construction Materials Lab. My expertise includes Fine Aggregate Lab (Specific Gravity, Angularity, Sieve Analysis), Coarse Aggregate Lab (Dry Rodded Unit Weight, Specific Gravity and Absorption, Sieve Analysis), Concrete Mix design (Slump, Unit Weight, Air Content Tests), Wood Strength Lab (Compression, Shear and Flexure Tests), Concrete Strength Lab (28-days Cylinder Breaks, Split Cylinder and Flexure), and Metal Strength Tests etc. I have capability to do the experiments independently and handle all related materials.

 

Steel Structure:

 

I have 3 years job experience as  'Structural Engineer' in pre-engineered steel building company in Bangladesh. I can design steel structure whether it is shed, single-story, multi-story or even high rise tower independently. Along with main frame design I also do connection design. I have good command and expertise over Staad Pro V8i software.  With basic knowledge on steel detailing and fabrication, erection process I can confidently work in steel building sector. Some major projects designed by me include Bangladesh Petroleum Corporation's Roof structure, Bangladesh Navy's headquarter project, Akij Cement Factory's silo structure, TK Group's chemical shed factory etc.

​

RCC Structure:

 

Though I am primarily engaged in steel structures at my job field, I have done my undergrad thesis on retrofitting process of existing building. Moreover, I was a part of an retrofitting project which was retrofitted by concrete jacketing and steel plating. During my job life I also worked on foundation design including footing, grade beam, short column etc. I possess basic knowledge on soil test report, digital survey etc. I possess adequate knowledge about deep foundation, shallow foundation, piling, liquefaction effect etc.

​

​

Earthquake Engineering:

 

Earthquake is an major issue in today's world. I have strong interest on it and I always try to study more and more for earthquake resistant building design. My undergrad thesis's retrofitting process was based on seismic evaluation of an existing building and retrofitting of the failed members. I did time history analysis for the evaluation purposes. During my job life I designed steel building considering proper seismic loads. I used UBC 1994 option on Staad Pro V8i software and followed BNBC earthquake design code.

​

Environmental Engineering:

 

I observed the mechanism of treating waste water in a wetland project which was conducted by my seniors as a part of their research. The wetland used natural resources mainly, insects etc, and was capable of transferring black lake water into clear water. Moreover, I possess basic knowledge about water purification, BOD, COD, different types of filters etc.
