About

I am a PhD-trained Mechanical Engineer with experience in designing, manufacturing, and validating complex hardware systems. My background spans precision manufacturing, semiconductor-derived processes, and additive fabrication, with hands-on experience across the full engineering lifecycle: from design and simulation to fabrication, integration, and testing. While much of my work has involved MEMS and medical technologies, my core strength is rigorous, adaptable engineering and solving technically constrained problems. I am seeking engineering roles where strong fundamentals, hands-on development, and system-level thinking are valued, and where collaborative teams built on trust enable learning, ownership, and technical growth. Specialties: Mechanical Engineering | Hardware Design & Prototyping | Precision Manufacturing | Additive Manufacturing | R&D Engineering

  • Doctoral Researcher at KTH Royal Institute of Technology
    Feb 2020 - Jul 2025 · 5 yrs 6 mos

    Research Activities: As Project Lead for remotely controlled drug delivery microsystems, I designed silicon microdevices and sub-micron thin metal/ceramic membranes for ultrasonic actuation. My work bridged theoretical research and numerical simulations of coupled fluid-structure interaction (FSI) using Multiphysics FEA software. I developed comprehensive fabrication process flows, including mask design for both mask aligner and maskless direct laser writing (DLW) lithography, and optimized parameters for PVD, DRIE, and precision dicing. Cleanroom validation included contact/optical profilometry and SEM imaging. I also developed experimental benchtop setups using ultrasonic transducers, drive circuitry, and high-speed imaging to validate device resonance. This expertise extended to the design and testing of membrane-based piezoelectric ultrasonic energy harvesters. Additionally, I led projects utilizing Two-Photon Polymerization (2PP) for micro-scale 3D printing of drug delivery microneedles and handheld inhaler nozzles. Key focus areas included mechanical design, simulation, and throughput optimization. My metrology work involved developing SEM process flows for non-conductive polymers and laser diffraction imaging for aerosol characterization. Teaching Activities: As a Teaching Assistant for the KTH Master’s course "Micro and Nanosystems" (EK2350), I led laboratory sessions on thin-film temperature sensor fabrication and response evaluation. I coordinated with faculty to organize lab sessions and the re-organization and editing of course materials to adapt to remote teaching requirements. Other Activities: Metrology Tool Responsible: Managed SEM and Optical Profilometer tools within the MyFab infrastructure. Responsibilities included training new users, performing equipment maintenance, and resolving daily operational issues to ensure tool availability.
