I’m an engineer with both industry and academic research experience, where I have built and deployed custom scientific instruments, written control software, and worked across hardware, data, and software systems to help quantify the world around us.
I take a practical, systems-level approach to engineering and enjoy learning how complex parts fit together, whether it’s hardware, code, or people, to design reliable, understandable, and genuinely useful solutions.
I’m currently looking for roles in NYC where I can apply my strong engineering fundamentals, problem-solving mindset, and clear communication skills to meaningful work.
Outside work, I enjoy searching for the best savory bites and creating small moments that bring people together.

Graduate Research Assistant
· Carnegie Mellon University- Developed instrumentation to measure sub-3 nm atmospheric aerosols, enhancing sensitivity and increasing measurement frequency by 100x
- Designed, conducted experiments, and built quantitative models to evaluate the performance of new particle measurement techniques, leveraging approaches grounded in established scientific literature
- Designed and implemented a Python-based data pipeline for a custom particle sizing instrument, integrating real-time data collection, analysis, and visualization thus improving lab-wide access to high-resolution aerosol size distributions to derive quantitative insights about air quality
- Authored scripts to automate data processing and visualization of large sets of field observation data to uncover patterns and correlations in aerosol nucleation activity
Process and Tooling Engineer
· HP Inc- Improved plastic welding processes through design of experiments and statistical analysis, and implemented leak test solutions through fixture design and test optimization to ensure product quality for 10+ SKUs at a 20 part-per-minute production line
- Collaborated with international cross functional teams and interfaced with contract manufacturers to align on process improvements and new products
- Spearheaded and supported implementation of a new weld joint design for a cost avoidance of $2 million in capital investment
- Chaired Young Employee Network focused on providing opportunities for professional development and networking to increase employee engagement with 3–4 events per quarter with an average attendance of 30–50
