From Mathematics to Humanitarian Relief

Rostislav Filippenko, a Ukrainian mathematician based in Madrid, never imagined he would find himself in the middle of a war zone. While visiting his family in Kharkiv, Ukraine’s second-largest city, the Russian invasion began, leaving him with a difficult decision—flee or stay to help.

Despite the danger, he chose to remain in Kharkiv and support those in need, shifting from academia to humanitarian work overnight.

Kharkiv Under Siege

Once a bustling metropolis of 1.5 million people, Kharkiv has become a battlefield.

"It looks like a scene from The Walking Dead," Rostislav told Euronews, describing the empty streets, shattered windows, and widespread destruction. The city's infrastructure is in ruins, and residents endure constant airstrikes and shelling, struggling to survive under the relentless attacks.

A Growing Medical Emergency

One of the biggest humanitarian crises in Kharkiv is the severe shortage of medical supplies.

• Hospitals are overwhelmed, treating an increasing number of wounded civilians.
• Elderly residents and people with chronic illnesses face life-threatening situations due to the lack of essential medications.
• Volunteers risk their lives daily to deliver humanitarian aid under constant bombardment.

Rostislav quickly realized the urgency of the situation and stepped in—not as a soldier, but as a lifeline for the city's most vulnerable.

From Mathematician to Humanitarian Worker

Before the war, Rostislav worked as a mathematician in Spain. Now, he collaborates with local humanitarian teams in Kharkiv, working tirelessly to:

• Source and distribute critical medical supplies to hospitals.
• Deliver food and medicine to people trapped in war-torn areas.
• Support local defenders who are protecting the city from further attacks.

Despite the challenges, he remains committed to helping people survive the war in any way possible.
