Data science series: Two experts helping utilities make the invisible visible
To find out more about how Xylem is applying data science in the real world, Making Waves is profiling some of our experts on the power and potential of distilling data into actionable insights.
In this third and final part of our series, we spoke to Greta Vladeanu and Amin Ganjidoost about how they got into data science and what they enjoy most about their work.
INTERVIEWEE: Greta Vladeanu, Data Scientist at Xylem
How did you get involved in data science?
My passion for problem solving began as a student. I moved to the United States in 2018 to study technology at Indiana State University and went on to do a PhD in Louisiana Tech University, focused on risk modelling for gravity sewers.
My advisor introduced me to the team at Pure before it became part of Xylem. I was impressed with the company’s work, particularly around condition assessments of underground pipes. After my PhD, I joined the company as an engineering analyst, and I haven’t looked back.
What do you like most about your work?
I get to work with a diverse team, one where we all think differently and constantly explore innovative ideas. No one works on a solution from start to finish without help from the team, so we’re always learning from each other. That way of thinking helps us identify the best solution, which better helps the client in return. It’s also really fulfilling working on so many different projects. No project is the same – there is always something different that we need to figure out, like exploring a different methodology we haven’t done before.
How do you see the role of data science evolving?
The role of data science is evolutionary by nature – particularly in terms of optimizing utility operations. The more data that’s collected and analyzed over a longer period will only help us fine-tune solutions further, allowing utilities to optimize capital replacement projects well into the future.
For us, data analysis isn’t a one and done. It’s a continuous interrogation of what’s happening at any given time across a utility’s network. As a utility, imagine having a bank of historical data that can help inform operational decisions for years to come. The opportunities are endless, and I’m so excited to bring our clients on this journey.
Do you have any interesting hobbies outside of work?
I love to bake, and sourdough bread is a particular favorite of mine. I started making it during the pandemic, and now I do it every week without fail. It’s a science in itself, getting the mix just right! It took some time to perfect the recipe, but I think I have it mastered now.
INTERVIEWEE: Amin Ganjidoost, Drinking Water Decision Science Manager at Xylem
How did you get involved in data science?
During my graduate studies at the University of Waterloo, I used data analytics, mathematical modeling, and system dynamics to develop a decision support system for the sustainable management of water distribution and wastewater collection networks.
That’s really where my passion in terms of taking an analytical approach to solving water began. Knowing how to interpret data – going beyond surface level figures to find the most valuable information – is incredibly important in achieving the best outcomes. I’m so lucky that I get to help our clients use data to their advantage so that they can develop holistic solutions that deliver transformative benefits to their communities.
What do you like most about your work?
As data scientists, we make magic by extracting value out of data. I really enjoy showing utilities how they can save tons of money on investments by putting data to work in the right way. I love collating data, finding gaps, and plugging them with artificial intelligence. The answer is always there, it’s just a case of using the right tools and expertise to find it.
How do you see the role of data science evolving?
The beauty of data is that it knows no bounds. Knowledge is power and we can use it to our advantage by breaking down the barriers that exist within the sector to build a more resilient future. Solving water will not be achieved in isolation, every part of the industry has a role to play.
Do you have any interesting hobbies outside of work?
I love to travel and experience new cultures, road trips, hiking and outdoor activities with family and friends.
