Move beyond memorization
Traditional diagrams are useful, but they cannot fully show how concentrations, reaction rates, pathway activity, and cellular conditions influence one another over time.
About Gunnar BioTech
Making complex biology easier to explore.
Gunnar BioTech develops interactive scientific software that helps students and researchers move beyond static diagrams and experience biological systems as connected, changing processes.
Our purpose
Our Mission
Biology is dynamic, interconnected, and constantly changing. Our mission is to create accessible tools that allows users to observe those systems in motion, test ideas, and develop a deeper understanding through interaction.
Learn through experimentation
Interactive simulation allows users to change conditions, observe consequences, ask better questions, and connect biochemical theory with visible behavior.
Build useful scientific tools
We aim to combine scientific rigor, thoughtful design, and approachable interfaces so advanced biological concepts are easier to investigate and communicate.
The person behind the company
About the Founder
Nicolas Gustafson
Founder, Gunnar BioTechnology LLC
I am a Philadelphia native who has spent the last six years here in Blacksburg, Virginia. I graduated with a bachelors degree in biochemistry from Virginia Tech in 2023, which I later followed up with a master's in entomology with a focus in molecular biology, graduating in 2026. I also served six years in the US Marine Corps Reserves, of which I retired in May of 2026. I have a passion for all things chemistry and am excited to have finally rolled out my first project here at Gunnar BioTechnology. It has taken four years of development to finally roll out the beta, and I am extremely excited to see where it goes.
“
I created Fluxion with the intent to improve the way in which students learn about the fundemental pathways of human metabolism. It feels like yesterday when I was sitting in my first detailed biochemistry class doing my best to memorize the steps of glycolysis. I created Fluxion because I believe learning about metabolism should be done dynamically, not only via memorization.
How we work
Our Core Principles
These principles guide how Gunnar BioTech approaches product design, scientific modeling, education, and future development.
Scientific Accuracy
Models are developed around established biochemical principles and are refined as the software, supporting data, and scientific understanding evolve.
Education First
Every feature should help users understand a biological process, investigate a question, or connect theory with observable behavior.
Interactive Exploration
Users learn more when they can adjust conditions, test hypotheses, inspect results, and follow relationships across a system.
Clarity and Accessibility
Complex scientific information should be presented through thoughtful interfaces, clear visualizations, and approachable explanations.
Transparency
Assumptions, limitations, references, and simulation behavior should be communicated as clearly as possible.
Continuous Improvement
Feedback, testing, new scientific information, and real-world use all contribute to the continued development of the platform.
Built for scientific computing
The Technology Behind Fluxion
Fluxion is developed with modern scientific-computing and visualization tools selected to support numerical simulation, interactive interfaces, data exploration, and continued expansion.

Our development story
Company and Product Timeline
Fall 2022
Simulate Metabolism
Sitting in VT BCHM 4115, I had my first idea to create an interactive game-like program that simulated the major pathways of metabolism. I spent four years teaching myself basic software development and molding the idea.
June 2026
Gunnar BioTech Founded
Gunnar BioTechnology was founded on June 17, 2026, with the intention of bringing together a development team that could help take Fluxion to the next level.
Spring 2026
First Fluxion Prototype
The intitial fluxion prototype was a product of four years of devlopment into a dynamic metabolism simulator. Early development was slow and painstaking, but necessary to create the foundation Fluxion is built on.
Spring 2026
Beta Program
Beta testing began in the spring of 2026, where a rapid succesion of new implementation and bug fixes have been rolled out.
Future milestone
Near Future Goals
Major new additions to FLuxion are in the works. A MacOS verison is under development, along with a plethra of new pathways coming down the pipeline. A licensing system is also being created to allow for a public rollout.
Where we are going
Product Roadmap
Deepening the metabolic model
- Expand pathway coverage and biological conditions
- Improve kinetic behavior and regulatory systems
- Refine visualization and metabolite-analysis tools
- Add tutorials, guided exercises, and documentation
Broader biological systems
- Blood glucose balancing
- MacOS development
- Classroom learning options
Multi-scale biological simulation
- Whole-cell and multi-system modeling
- Tissue or organ-level simulation concepts
- Research-oriented model customization
Roadmap items represent development goals and may change as the platform, scientific priorities, and user needs evolve.
Scientific foundation
References and Model Transparency
Fluxion is developed using established biochemical literature, documented kinetic relationships, and scientific references wherever possible. As the platform grows, supporting sources, model assumptions, and known limitations will be collected in a dedicated references section.
