Aachen, North Rhine-Westphalia, Germany
As a Senior Researcher at the RWTH Aachen University, Germany, I am currently designing RF hardware for future 6G communications. My responsibilities include establishing PCB prototyping and measurement facility, leading a team of PhD and masters researchers. Of course I also work on my favourite topic i.e. designing innovative antennas/phased arrays. I worked on advancing in-body and off-body wavefront shaping technology to enable deep-body implanted device powering, off-body communication and sensing to enhance healthcare technologies during my PhD in France. My research builds on a strong foundation from IIT Kanpur, where dual degree in Electrical Engineering fostered skills in telecommunication, electromagnetics and semiconductors. Past roles, including as Senior Embedded Engineer at Honeywell Inc., contributed practical experience in embedded systems and Linux development, complementing academic accomplishments.
Developing Non-Invasive Power Solutions for Medical Devices Using Advanced Antenna Systems Key Areas of Expertise: Wireless Power Transfer (WPT) Wavefront-Shaping for In-Body Devices Mid-Field Focusing Techniques Leaky-Wave Antenna Systems Biomedical Engineering & MedTech Innovation
PhD focused on lightweight, body-conformal mmWave antenna arrays for wearable devices. Designed and prototyped innovative leaky-wave antennas (LWAs) on flexible PCBs, with rigorous theoretical models rooted in array and leaky-wave theory to predict and optimize directivity, gain, and polarization. Full-life-cycle RF system development, from propagation-channel characterization and link-budget analysis to front-end integration and performance validation to using tools such as ANSYS HFSS, CST, ADS, and QuCS.
1. Engineered and optimized specialized antennas for UAV Command and Control (C&C) systems, ensuring robust performance in harsh operating environments. 2. Conducted in-depth link budget analysis and designed high-performance RF front-ends using CoTS components, validating and optimizing for IP3 and SNR via ADS/QuCS simulations. 3. Augmented radar performance by implementing a data-driven, federated machine learning (AI/ML) approach for object detection, successfully replacing traditional signal processing methods.
In this role, I was responsible for architecting new avenues for revenue and market growth on both a global and regional scale. I successfully identified an $8 million opportunity in the aftermarket sector and developed a comprehensive model to capture this value worldwide. Additionally, I spearheaded the strategic initiative to penetrate the South Asian aviation market, creating a targeted plan to deliver cutting-edge in-flight connectivity solutions to airlines in this key emerging region. My work laid the foundation for significant long-term growth and service expansion.
Firmware & SoC Security: Fortified system security by implementing a Hardware Root of Trust (HRoT) within the boot code. This established trust from the initial boot sequence, securing both the firmware and software layers against tampering. Low-Level Driver Development: Authored and implemented robust hardware drivers for essential communication protocols, including SPI and UART, on ST microcontrollers to ensure seamless data exchange and peripheral control. Embedded Linux Customization: Developed tailored Embedded Linux environments for state-of-the-art microprocessors. This involved deep customization and optimization of the Linux kernel and bootloader to meet specific hardware and performance requirements.
I engineered advanced metasurface cloaks for stealth applications. My key contributions include: 1. Developing an advanced technique to significantly reduce the Radar Cross-Section (RCS) of large objects using a thin, periodic metasurface. 2. Formulating a robust analytical model that calculates the exact reactive impedance needed to cancel wave scattering. 3. Solving for challenging conditions by ensuring the cloaking is effective even for oblique wave incidence, advancing the practicality of next-gen stealth technology.
