Data Journalist & Educator
Hi! I'm Ada. I am a freelance data & investigative journalist and teacher. Over more than 10 years, I made a lot of stories with small and big datasets and I am here to share what I learned along the way.
From the start of my career, I’ve loved helping other journalists get comfortable with data, brecause I believe these skills should be for everyone. Over the years, I’ve given countless lectures, taught at conferences like Dataharvest and NICAR, given guest lectures in the Master’s program in Gothenburg, and mentored journalists 1:1 through programs like IJ4EU.
I founded Data Frosch by accident, because I bought a frog hat last winter. It's a fun way to put myself out there and help others find me.
