Arjun Bala Krishnan

I manage data from various systems, visualize insights with Power BI, and lead projects to improve efficiency. I also serve as the product owner of a customer cost prediction tool for Sales. By enhancing data quality and automating processes, I drive better decision-making in the company. My analytical work promotes a culture of using data for smarter choices, keeping us ahead in the market. Through ongoing review and adaptation, I cultivate a team culture focused on working smarter, not harder.

I offered software and IT assistance to the Atomic-Scale Characterization group, while also compiling technical publications based on my previous contributions. Utilizing software I developed for the institute, I analyzed extensive data sets from APT experiments during my previous tenure with the department

In my Informatics Project, I analyzed extensive APT datasets using clustering algorithms and statistical analysis, developing a Python GUI app for 3D layer analysis and composition detection, leading to a research paper. Simultaneously, I conducted experiments for multi-scale characterization of Gear material, resulting in a published article. Additionally, I performed APT characterization of Iridium nano-wires via electrochemical processing, that yielded a high impact research work.

At the Materials Synthesis and Processing department of Jülich research center, I studied aviation materials known as Thermal Barrier Coatings using image processing and deep-learning in Python. By collecting experimental data, including electron microscopy, mercury porosimetry, and roughness measurements, I developed a method to assess material characteristics solely through sample images, minimizing future manufacturing losses.

As an intern in the thermal spray department of Lufthansa Technik's aircraft engine division, I focused on Python software development for a metallography image application and the calibration of a new mobile adhesion-testing device. I also handled technical documentation for a heat simulation program, prepared data for cleaning and etching processes, and maintained in-house activity logs and KPIs through MS excel.

Assisted in the industrial projects at the Materials Science and Technology division for two years. My functions were as a foundry worker, metallographer, and material tester. I prepared various castings and conducted mechanical testing, spectroscopy, electron microscopy, chemical analysis, and characterization of aluminum alloys.

I worked as a contract resource for the operations department in the company, providing assistance in managing the product database and related software solutions. I worked in close cooperation with the engineering team in fulfilling customer requirements using an Enterprise Resource Planning tool.

For my master's project, I wrote a thesis report on material informatics, which involved using image analysis and neural networks. The findings were supported by experimental results.

For my bachelor's project, I designed the draft of a sulfur absorber pressure vessel used in chemical plants.
