Ms. Petrova is a Russian scientist who works in a lab at Harvard Medical School. She told her story through a Times Opinion editor, Alex Ellerbeck, over multiple calls from an ICE detention center.
When I moved to America from Russia to join a biology lab at Harvard Medical School in 2023, it felt as if I found my dream job. America was a paradise for science. Everything was flourishing. There was freedom of discourse; conferences, seminars. It was nothing like the environment I had left behind in Russia, where international sanctions meant there weren’t enough supplies to do experiments and I once declined a job offer that was contingent on me no longer protesting the war in Ukraine. After I was arrested for taking part in a protest, I fled the country, knowing that I could not continue to live or work as a scientist there.
My background is in bioinformatics, a field that uses computational tools to understand biology. In my lab at Harvard, I worked with a microscope that we called NoRI (short for Normalized Raman Imaging). This microscope, which was created in our lab, is the only one like it in the world. What makes it unique is its ability to measure the chemical makeup of cells to an astonishing and novel degree of precision, offering new insights into disease and aging that could one day pave the way for healthier life spans and treatments for diseases like Alzheimer’s and cancer.
There is so much beauty in what we can learn through science, in how complicated life is, and in trying to understand how it works. It’s what motivates me to wake up every morning.
I haven’t been in my lab or worked with my microscope since February, when I was detained by U.S. Immigration and Customs Enforcement as I was returning to Boston from a vacation in France. At Logan International Airport, I did not complete a customs declaration for frog embryos (for use in our lab’s research) in my luggage. I’m told this would normally result in a warning or a fine. Instead, my visa was revoked and I was sent to a detention center in Louisiana, where I have spent the past three months with roughly 100 other women. We share one room with dormitory-style beds.
I’m used to spending up to 12 hours a day in the lab, talking with colleagues about tricky scientific questions and fine-tuning the algorithms used for NoRI. At the detention center, there is no access to computers and six phones are shared among all of us. The calls cost $5 for 15 minutes, at which point they cut off. It’s constantly noisy and cold. Fortunately, my beautiful colleagues have mailed me academic articles and books (I’m reading a wonderful one now about biochemistry called “Transformer” that I recommend to everyone).
I’ve asked a colleague to share some of the images from NoRI with The Times. Maybe if people see them, they will understand why I want to get back to work. Until now, no one outside our lab has seen these images, which are of tissue samples taken from mice and rats that we hope will provide greater understanding of how organs age and diseases develop in the body.
