Research Philosophy

I am drawn to engineering problems in which physical insight, mathematical rigor, and thoughtful design must work together. Across high-power optical systems, bioreactors, autonomous robots, reactor physics, and orbital mechanics, my underlying interest is the same: to understand governing physics deeply enough to design, build, analyze, and control systems that behave reliably in complex environments.

My work spans physical-system design and scientific computation—from developing mechanical and optical assemblies to constructing first-principles models and purpose-built learning algorithms. I use machine learning as a mathematical engineering tool, designing architectures, objectives, and loss functions around a problem's governing physics to support analysis, optimization, inference, and control. Computation is not a substitute for physical understanding; it is one means of extending what we can understand and create.

I am most motivated by problems that have not yet been neatly packaged. I enjoy identifying the underlying technical question, determining what must be understood, and creating the mathematical, computational, or physical tools required to pursue it. My aim is not merely to analyze existing systems, but to originate useful methods and working systems that others can test, apply, and extend.

In the long term, I hope to bring this combination of physical design, computational physics, and intelligent control to autonomous marine technology. I am particularly interested in systems capable of responsibly exploring, monitoring, and interacting with difficult environments—engineering tools that make complex phenomena more knowable and ambitious physical systems more achievable.

About

The Researcher

Portrait of Cassidy Vetrovec

Bridging artificial intelligence, computational physics, and engineering design.

I am a Mechanical and Aerospace Engineering student at the University of Florida (UF), completing dual B.S. degrees with a Minor in Mathematics. I work on both sides of the boundary between equations and hardware: deriving physical models, developing scientific software, designing mechanical and optical systems, fabricating components, and integrating sensing and control.

My work includes government-funded laser research at Aqwest (www.aqwest.com), where I have independently developed new computational approaches for advanced optical systems; robotic and bioreactor development in the UF SYBORGS Laboratory, involving physical design, fabrication, integration, and testing; and self-directed projects in gravitational-wave physics, orbital mechanics, reactor simulation, and scientific machine learning. Across these settings, I aim to create more than analyses or demonstrations, but rather, to create reusable methods, working systems, and clear technical foundations that make further work possible.

Several of my projects began not with prior expertise, but with a question I could not leave alone. Pursuing them required me to teach myself JavaScript and Three.js for an orbital and gravitational-wave simulator; neural-network formulation and custom objective design for laser optimization; coupled neutronics and thermal modeling for reactor simulation; and PCB design and embedded electronics for robotic systems. I tend to follow a problem until I have acquired the mathematics, software, and physical understanding needed to make something of it. Unfamiliarity has rarely felt like a boundary; it is usually where the interesting work begins.

I am preparing for graduate research in intelligent physical systems, where I hope to bring this breadth to problems requiring both theoretical depth and physical realization.

Research Trajectory

Autonomous Systems for Difficult Environments

My long-term research direction is autonomous robotics for difficult and poorly observed environments, particularly marine systems supporting seabed-resource exploration, environmental monitoring, and regulatory compliance. I hope to combine physical-system design, intelligent control, scientific machine learning, and multimodal sensing to create systems that remain capable under uncertainty, sparse measurements, limited communication, and severe environmental constraints.

My background in laser and optical systems is part of this trajectory rather than separate from it. Optical sensing, imaging, ranging, and communications—used where environmental conditions permit and integrated with acoustic, inertial, and other sensing modalities—can provide important capabilities for difficult-environment robotics. Graduate study would allow me to deepen this foundation and apply it toward autonomous systems that can perceive, reason, and operate reliably where direct human access is limited.

Why I Build

Personal

I came to engineering through philosophy and mathematics. Philosophy taught me to remain dissatisfied with shallow explanations; mathematics gave me a language for making ideas precise; engineering supplied the decisive test—the idea must survive contact with the physical world. That progression still shapes how I approach research.

I am motivated by the pursuit of excellence—not as prestige or perfectionism, but as disciplined workmanship. It means understanding the assumptions beneath a model, attending to consequential details, designing and fabricating with care, validating claims honestly, and continuing to refine a system after the excitement of the first idea has passed. In difficult engineering, these habits are not ornamental; they are often the difference between an impressive concept and a reliable result.

I am also comfortable departing from convention when the evidence warrants it. I question inherited assumptions, test alternatives, and accept the possibility of being wrong. In engineering, however, originality must earn its keep: an unconventional idea must still survive mathematics, experiment, fabrication, and use. That independence is personal as well as technical; I prefer to choose deliberately how I work and live rather than accept convention as sufficient justification.

Outside research, I am a student pilot, an entrepreneur, a hiker and backpacker, and a persistent reader of philosophy and history. Aviation and time spent outdoors continually renew my appreciation for precision, judgement, and humility in environments that cannot be negotiated with.

Strain-Gauge Cantilever Scale: Physics-Based Estimation vs Experimental Calibration

experimental mechanicsmechanics of materialsscientific communicationuncertainty quantificationlabview

Mechanics of Materials Laboratory: Built and instrumented a 6061-T6 aluminum cantilever scale using a bonded strain gauge, quarter-bridge Wheatstone circuit, signal amplification, a 14-bit data-acquisition device, and a custom LabVIEW interface. I developed two independent methods for inferring applied load: a first-principles model derived from beam-bending mechanics and strain-gauge response, and an empirical model obtained through four-point calibration. I compared their accuracy, repeatability, and propagated uncertainty under repeated placement and progressive unloading. The calibrated method closely matched reference measurements, while the mechanics-based method remained repeatable but exhibited a systematic sensitivity discrepancy.

Two-Part Individual Astrodynamics Project: Developed a modular MATLAB toolchain for reconstructing and propagating an unknown spacecraft orbit from a single Earth-centered inertial position and velocity state. In Part I, I derived the true-anomaly time-of-flight integral, implemented Gauss–Legendre quadrature, recovered orbital properties and node-crossing times, and evaluated numerical convergence. Part II extended the analysis through Newton-based anomaly propagation, position and velocity reconstruction, ECI-to-ECEF transformation, geocentric longitude and latitude calculation, three-dimensional orbit visualization, and Earth-relative ground-track analysis.

Mechanical Characterization through Tensile & Compression Testing

Mechanics of Materials Laboratory: Characterized the tensile response of an unknown metal, biaxial carbon-fiber composite, and nylon, together with the compressive response of plaster of Paris, using an Instron 5967 Universal Testing Machine. I converted load, extensometer, and crosshead-displacement measurements into engineering stress–strain curves, correcting non-extensometer measurements for machine compliance. From these results, I evaluated elastic modulus, yield behavior, ultimate and fracture strengths, toughness, elongation, specific properties, failure modes, and measurement uncertainty. The unknown metal’s measured mechanical behavior was most consistent with 2014-T3 aluminum.
