A Day in the Life as a Data Scientist in Milwaukee

Data science is one of the most dynamic fields in tech today, and it’s reshaping industries worldwide. At Johnson Controls, data scientists use their expertise to drive innovation in building efficiency and sustainability. We analyze complex datasets, create predictive models, and develop algorithms that help our clients optimize energy use and improve building management systems. This field is rapidly growing, and Milwaukee is emerging as a hub for eco-tech and innovation.

What is Data Science?

Data science is all about analyzing large amounts of information to find patterns and insights that help businesses make better decisions. Data scientists use tools like programming languages (such as Python and R) and statistical methods to work with this data. We create visualizations and use machine learning to predict outcomes. You’ll find data scientists working in many industries like finance, healthcare, retail, and tech, helping companies spot trends, improve processes, and solve problems.

Morning Brew

On a crisp Milwaukee morning, I begin my day at Colectivo Coffee in the Historic Third Ward, sipping a latte while scrolling through social feeds and catching up on the news. Afterward, I hop on my bike and ride to the Johnson Controls headquarters. I work on-site a couple of days a week, while the rest of my tasks are done remotely from my home office or one of my favorite coffee shops – there are so many good ones!

9:00 a.m.

Team Sync-Up

I join a team stand-up meeting where we share progress, address challenges, and plan our priorities for the day. Today, we’re tackling improvements to our energy prediction model, ensuring it can scale for various building types. As a senior data scientist, I lead the technical discussions, guiding our team through potential solutions and aligning our work with Johnson Controls’ sustainability goals.

10:00 a.m.
Digging into Data

After my meeting, I settle into a focus work session, diving into our latest building performance datasets. Our team is currently refining a model that predicts energy consumption trends, incorporating both environmental and operational variables. The goal is to optimize building efficiency for our clients by identifying patterns and suggesting sustainable solutions that significantly reduce energy costs. It’s a challenging task, but the fulfillment comes from knowing that my work directly contributes to reducing the carbon footprint of buildings worldwide, promoting a more sustainable future.

Afternoon

Lunch in Walker’s Point

Since it’s an in-office day, I head out to Walker’s Point for lunch with colleagues at Fuel Cafe. It’s warm in the afternoon, so we grab a table in the sun. It’s a great chance to share insights and connect outside the office. After refueling, we return to the office feeling energized and ready to tackle the rest of the afternoon.

Analyzing, Reporting, and Strategizing

Back at my desk, I prepare reports for management, outlining trends, patterns, and predictions from our latest data. These insights help identify opportunities to optimize sales and profitability. Today, I’m refining pricing strategies to align with market trends and client behavior, aiming to boost revenue while maintaining competitiveness. It’s fulfilling work that directly impacts our business strategy.

After wrapping up my work, I review my progress and plan for the next day. Milwaukee’s vibrant after-work scene offers plenty of ways to unwind. I’ll head to Lakefront Brewery with friends in the evenings or take my dog for a stroll along the scenic Riverwalk. In the summer, I enjoy visiting the city’s beer gardens or exploring the Bay View neighborhood, which has a restaurant for every craving. Whether it’s classic Wisconsin cheese curds or upscale eats, there’s always something new to try.
