Our colleague and great friend of our department, Doctor of Technical Sciences Alexander Danilovich Cherenkov, died of complications as a result of Covid-19. He was one of the pillars of biomedical engineering in Ukraine – professor at the Department of Biomedical Engineering and Electrical Engineering at KhNTUSG named after Petra Vasilenki. Alexander Danilovich Cherenkov gave a start in life to many of our candidates and doctors of sciences. In many of their dissertations, he was either an official opponent or gave feedback on abstracts, and was always fair, strict and benevolent at the same time. He was a reviewer for master’s theses and an internship supervisor for our teachers. Ukraine has lost one of the leading scientists in the application of biomedical engineering and information technology in agriculture.

We express our condolences to his family and colleagues.
