Christoph Koettl
I am a reporter on the Visual Investigations team of The New York Times, where I examine photos, videos and satellite images in search of hidden clues that reveal new insights about current events.
What I Cover
I cover a broad range of topics, including international wars, policing in the United States and North Korean smuggling networks. My stories scrutinize official accounts of events that are often misleading or false.
My Background
I have almost two decades of experience using innovative tools and methodologies for reporting and research, focusing on violations of human rights and the laws of war. My specialty is geospatial analysis and using satellite images to tell stories. I have shared in two Pulitzer Prizes for coverage of the civilian toll of U.S. air and drone strikes and Russian atrocities in Ukraine.
I have published several academic papers and book chapters on digital sleuthing. In 2009, I testified as an expert witness at a congressional hearing on the armed conflict in Sri Lanka.
Journalistic Ethics
I want all of my work to be accurate and fair and adhere to the standards of integrity outlined in our Ethical Journalism Handbook.
