Hi there! I'm Ashique Anan Abir, and I have a bachelor's degree in Electrical and Electronic Engineering (EEE). My journey in engineering has been exciting and full of learning. I'm enthusiastic to learn about new and emerging technologies, which will allow me to approach real-world problems from multiple perspectives.
I'm passionate about several areas of technology and engineering. I love exploring different fields, from power electronics and renewable energy to embedded systems, artificial intelligence, machine learning, data science, and biomedical engineering. I believe that looking at problems from different angles can lead to unique and creative solutions.

I designed and built a prototype High-Voltage Arbitrary Waveform Generator that outputs complex bipolar signals with seven selectable, positive and negative voltage levels, reaching up to 100 V. This first version operates in the sub‑kHz range and involved end‑to‑end work across schematic design, PCB layout, and firmware to shape and control the waveforms. I'm now working on a next iteration to push higher frequencies, expand the voltage range, and add more output levels.
I've published some of my research papers from my completed projects and thesis, and I'm just getting started! I'm always on the lookout for new and exciting topics to explore, so I'll be updating this page with my latest findings. Check out the list below to see what I've published so far.

From pioneering cascaded H-bridge multilevel inverters in my undergraduate thesis to publishing IEEE conference papers based on my self-built test bench, my research journey has been electrifying! I then shifted gears as a Research Assistant at Giga Tech Ltd., where I harnessed my embedded systems know-how to develop a prototype mechanical ventilator, blending tech with healthcare. Professionally, I've powered through roles at Giga Tech Limited, mastering medical device accuracy, and at United Mymensingh and United Jamalpur Power Ltd., where I navigated the vast operations of power plants. These eclectic experiences fuel my passion as I steer toward my doctoral research goals.
Powered by a Cortex®-M4F-based MCU TM4C123G, it operated with and controlled several flow and pressure sensors, O₂ sensors, and CO₂ sensors connected via I²C, along with several controlling valves. It featured UART device-to-device communication with a Linux-based HMI.
