Independent Contractor / February, 2025 — Present

Contributed to 4 projects by writing evaluating or annotating scientific prompts for AI model reasoning training.

Research Scientist / January, 2023 — September, 2024

Steered the founding of a new electrochemistry R&D division at the company headquarters in Irvine, CA. Advised as a subject matter expert on electrochemical sensors multiple cross-functional teams involving research, development, regulatory, quality, production, and management department members. Led the glucose biosensor development from proof of concept to the internal validation stage. Achieved reduced R&D cost and future production cost through data-driven validation of an in-house fabrication process for multiplex electrodes, matching third-party vendor quality and performance. Attained a 2-fold extension of glucose biosensor sensing range through a design of experiments-based optimization of a multi-component polyurethane coating formulation. Decreased electrode material costs 100-fold through experimental data-backed selection of an alternative electrode material for enzymatic sensors fabrication, without loss in sensing performance.

Senior Research Scientist / November, 2021 — November, 2022

• Led the development of glucose and creatinine biosensors from proof of concept to internal validation stage. • Initiated early design and proof of concept phases for phosphate and cholesterol biosensors. • Troubleshot the glucose biosensor design to match regulatory expectations under a tight deadline before a schedule demo in front of potential future investors. • Sparked the exploration of alternative electrode materials with the aim of reducing third-party vendor costs. • Handled varied developmental stages of sodium, potassium, calcium, and pH ion-selective membrane sensors from initial concept to internal validation, optimizing formulations and improving data analysis workflows.

Postdoctoral Research Associate / June, 2019 — November, 2021

• Examined new dopamine dynamics associated with neurodegenerative diseases in specific functional regions of the fruit fly brain, as quantified using implantable microelectrodes. • Achieved single neuron resolution imagining and neuron quantification through protocol optimization of a tyrosine hydroxylase immunohistochemistry assay for fluorescence imaging of the dopaminergic system. • Aided in the process of writing grant reports and grant proposals for NIH grants.

Graduate Research Assistant / August, 2014 — May, 2019

Developed new implantable microelectrodes for nitric oxide and dopamine detection to achieve in vivo sensing. Established quantitative environmental health safety and toxicology profiles of a range of nanomaterials and chemical additives employed in the semiconductor industry and in consumer products. Demonstrated causative links between nanomaterial properties and their toxicological effects through comprehensive analysis of data from biological assays and conventional materials characterization methods.
