Until the early morning of February 24th, 2022, Ukrainian scientist Olena Iarmosh did not believe there would be a Russian invasion of Ukraine. Iarmosh grew up and had settled in Kharkiv, her beloved city in Eastern Ukraine and only 40 km away from the Russian border, where she worked for more than 16 years as a lecturer in higher education before fleeing to Switzerland. At approximately 5AM, she awoke to the sounds of bombing, hoping that they were merely the loud sounds of technical maintenance at the local power plant.

“My city looks worse now after the bombing than after two occupations by German troops,” says Iarmosh. Iarmosh remained steadfast in her apartment throughout the bombardment for nine days before fleeing westward, first in western Ukraine, until the bombing started there too.  She then fled to Switzerland, all the while ensuring her teaching duties online, and eventually landed a temporary position at EPFL with Gaétan de Rassenfosse.

In the meantime, de Rassenfosse and his team set out to quantify the impact of the war’s influence on Ukrainian research, with one of the most extensive surveys yet, analyzing the responses from roughly 2,500 Ukrainian scientists in autumn 2022. The results are published in Humanities and Social Sciences Communications.

“Our survey shows that Ukraine has lost almost 20 percent of top scientists, like Olena,” explains de Rassenfosse of EPFL’s College of Management of Technology, who was able to hire Iarmosh to work in his lab as a visiting professor.

 “Many of these emigrant scientists are under precarious contracts at their host institutions. Of the scientists who stay in Ukraine, if still alive, about 15 percent have left research, and others have little time to devote to research given the circumstances of war.”

The EPFL researchers found that research capacity in Ukraine, that is time directly devoted to research activity, is down 20 percent. The study reports that 23.5 percent of scientists still in Ukraine have lost access to critical input for their research, and 20.8 percent cannot physically access their institution. de Rassenfosse and his colleagues highlight in the study that “the provision of more and longer scholarships emerges as a paramount concern” for migrant scientists. As for scientists still in Ukraine, the study suggests that “institutions across Europe and beyond can offer a host of support programs, such as remote visiting programs, access to digital libraries and computing resources, as well as collaborative research grants.”

“From a purely academic perspective, moving abroad may actually be an opportunity to improve as a scientist, as our survey shows that being abroad means exposure to novelty,” continues de Rassenfosse.

Now at UNIL on a temporary contract, Iarmosh is living day-to-day in Switzerland, trying to juggle constraints imposed by employer contracts and her temporary Swiss permit. “In Ukraine, with my level of education, there were many more options that I could choose from. In Switzerland, I am less picky about the job and know that each opportunity will be a positive experience for me.”

Iarmosh continues, “Despite the war, Ukraine is doing a lot to keep researchers and scientists employed. Education in eastern and southern Ukraine is fully online. Ukrainian universities still want to keep us. They invite us to activities, ask us to supervise and continue research. It is a great privilege for all lecturers and researchers. They are trying to maintain a university education for youth.”

“More generally, our study shows that Ukrainian scientists are getting more and more disconnected from the Ukrainian scientific community, and this is dangerous for the future of Ukraine and Ukrainian research,” warns de Rassenfosse. “Policymakers must anticipate the renewal of the Ukrainian research system in order for scientists to return, and to train the next generation of Ukrainian scientists.”

“I am the biggest patriot of my city,” concludes Iarmosh. “Kharkiv is beautiful, the people, the mentality, the architecture, it is clean. I love Kharkiv. But the human loss has been colossal. Physically and mentally strong, patriotic, open-minded men stayed behind, fighting to protect Ukraine. We can rebuild buildings. It takes many years to build a new generation.”
