ine Portfolio

Hi, my name is Tobias B. Grun

I am a research scientist with a deep passion for data science, statistical analyses, and programming. I became interested in data analysis early in my career as a marine scientist and biomimetic researcher, where I discovered the power of data as a tool for understanding environmental patterns and processes. Statistical programming became my happy place and over time I consequently shifted my work towards data analyses, and programming became an essential part of both my work and personal projects, such as developing websites like this portfolio, and home automation systems with Raspberry Pi. To deepen my skills, I pursued advanced training in Machine Learning, which further fueled my enthusiasm for data science.

Philosophy

The core of my work focuses on using my expertise in data analytics and science to drive innovation. I am committed to continuous learning and consistently expanding my skills and methods to stay at the forefront of technological advancements. I also aim to utilize my knowledge in evidence-based management and Agile Methodologies to manage cross-functional teams and deliver impactful projects. My career aspirations are centered on the meaningful contribution to data-driven analyses while continuing to grow professionally.

Projects

NLP Sentiment Analysis of Yelp Reviews

In this machine learning project, I use Natural Language Processing (NLP) to analyze and classify customer reviews from Yelp. The goal is to accurately identify the sentiment of reviews, categorizing them as positive, negative, or neutral, providing insights into customer opinions.

Recommender Engine

I use the recommender system for collaborative filtering, content-based filtering, and deep learning to analyze user behavior and preferences. This allows me to personalize suggestions, enhance user experience, and increase engagement across various industries like entertainment services.

Customer Churn Prediction

The objective of this project is to build a predictive model to forecast customer churn for a telecommunications company based on customer demographics, account details, and service usage data. The project aims to identify key factors influencing customer retention that can be used for data-driven business decisions.

Global Nutrition and Obesity Trends

In this project, I explore global nutrition and obesity data to uncover patterns, trends, and correlations through clustering techniques and data visualization. The goal is to provide a comprehensive analysis that can inform health policy and interventions on a global scale.

Biomimetic Research

Biomimetic Research is an integrative approach combining biology and engineering sciences to address complex technical challenges. By examining evolved biological structures, biomimetics seeks to extract working principles of biological role models that inspire innovative technical solutions. This process relies on computational analysis and mathematical descriptions of the role models to manage and interpret intricate biological data, transforming raw observations into technical solutions. Through rigorous data analysis, biomimetics turns the complexity of natural systems into a framework for advancing technology.

Ecological Research

In my ecological research, I study how marine organisms interact within their ecosystems, focusing on biotic interactions, spatial distribution patterns, environmental factors, and habitat relationships. By combining field observations with experimental and analytical methods, I aim to understand how marine organisms interact with their environments and how that affects biodiversity and ecosystem resilience.

LED Sunrise Simulation (Raspberry PI Project)

In this Python project, I use a Raspberry Pi and RGB LED strip to create a sunrise effect, gradually transitioning in brightness from low to high while shifting from dark orange (early sunrise) to full-spectrum daylight. Designed as a gentle wake-up experience, this project combines Python scripting and hardware to create a custom ambient light simulation with a soothing, high-impact effect for the user.

Repository

Machine Learning

I use Machine Learning for various analyses and have compiled methods and workflows to improve my techniques efficiency. These are currently stored across platforms like Confluence and Markdown files. I’m migrating them into a structured, public GitHub repository for easy sharing. Feedback and discussions are welcome, as we all grow by learning from each other!
