Frandy Arroyo Vargas

I am Physics Engineer graduated at the Instituto Tecnológico de Costa Rica (TEC) and a concurrent Licentiate in Chemistry Engineering at the Universidad de Costa Rica (UCR). This unique combination allows me to approach problems from both a fundamental physics perspective and a practical chemical‐process viewpoint, ensuring that my solutions are robust, efficient, and scalable.

Undergraduate Researcher in Physics (Oct. 2024 – Apr. 2025)

At the Centro Nacional de Alta Tecnología (CENAT), I spearheaded pioneering research in blind tip reconstruction (BTR) algorithms for experimental atomic force microscopy (AFM) images. I implemented end‐to‐end differentiable models that accurately recover the nanoscale shape of AFM probes without external calibration samples. Through rigorous data preprocessing, noise filtering, and deep‐learning optimization—including custom loss functions and the NAdam optimizer—I enhanced reconstruction accuracy by over 30 % compared to baseline methods. This work sharpened my skills in Python and Julia, particularly in scientific computing, tensor operations, and algorithmic debugging, while reinforcing my ability to manage complex datasets and present results in high‐impact academic forums.

Laboratory Research Assistant (Oct. 2024 – Apr. 2025)

Simultaneously, I served in the Laboratorio Nacional de Nanotecnología (LANOTEC), where I operated and maintained advanced instrumentation (e.g., scanning electron microscopes, profilometers). I collaborated closely with multidisciplinary teams—chemists, materials scientists—to characterize nanostructured materials for energy and environmental applications. This role honed my attention to detail, adherence to safety protocols, and aptitude for cross‐functional communication.

Software Developer, Level Up Contest at Intel Corporation (Jul. 2023 – Sep. 2023)

As part of a competitive team sponsored by Intel, I led the design and development of an AI‐based autoencoder system to decouple signal from noise in antenna measurements. I architected the neural network in Python using TensorFlow, implemented real‑time data ingestion pipelines in LabView, and validated performance against live RF signal datasets. My solution achieved a 25 % improvement in signal‐to‐noise ratio and was recognized with a top‐three finish among 50+ teams. This experience deepened my software engineering practices—version control with Git, containerization, and collaborative code reviews—while reinforcing agile project management and rapid prototyping under tight deadlines.

Technical Skills

• Software & Tools: Proficiency in Microsoft Office, AutoCAD, SolidWorks, MATLAB, Aspen Plus, Pipe‐Flow, Minitab, LabView, COMSOL Multiphysics, Multisim.
• Programming Languages: Proficient in R, Python, and Julia for data analysis, visualization, and scientific modeling; familiar with Git, Docker, and CI/CD workflows.
• Methodologies: Lean Six Sigma Green Belt certified; adept at process optimization, statistical analysis, and root‐cause problem solving.

Complementary Education

I continually expand my expertise through targeted courses: Fusion Energy and Plasma Physics at Princeton Plasma Physics Laboratory; advanced Plasma Physics and Applications at TEC; and sustainable cooling systems in collaboration with MINAE and the UNDP. These programs have fortified my understanding of energy systems, thermodynamics, and environmental engineering best practices.

Soft Skills & Languages

I excel in both written and verbal communication (English C1, native Spanish) and possess foundational proficiency in Mandarin (HSK2). I adapt quickly to dynamic environments, collaborate effectively within diverse teams, and consistently deliver high‐quality results within deadlines. My proactive creativity and leadership have been sharpened through mentoring international students and leading community outreach initiatives.

Volunteer & Mentoring Roles

Since 2022, I've been mentorfor international students entering Costa Rican universities, guiding them on academic success and professional development. Earlier, I volunteered with TECHO in informal settlements—organizing fundraising, helping with building homes, and facilitating leadership workshops—and led environmental cleanup campaigns at Braulio Carrillo National Park. These experiences underscored my commitment to social impact, empathy, and civic responsibility.
