How did you start your scientific career? Was there anybody who influenced you the most?

“As for every young person graduating from high school, I had to make a choice about what to do in life. For me, it was at the beginning of 1970s. In the Soviet Union (as it was then), the debate on The Two Cultures – the sciences and the humanities – was at its height. It was initiated by the British scientist and novelist Charles Percy Snow in 1959. In the Soviet Union, it took the form of a discussion between “physicists” and “lyricists” on various aspects around the importance of each to the development of society. For me, this discussion had real meaning, as I had some innate talent for painting, and in my teens had attended various art studios. However, the impressive achievements and practicality of the natural sciences eventually put the “physicists” at the top of my list, and after some hesitation I decided to become one of them. So, I entered the radio physics department of Kyiv Shevchenko National University.

After graduation in 1977, I became a technician at the Department of Gas Electronics, studying the interaction of high-energy ion beams with matter, at the Institute of Physics of the National Academy of Sciences of Ukraine (NASU, back then the Academy of Sciences of the Ukrainian SSR). Experimental setups were gigantic there and all this machinery needed megavolts and megawatts of electricity to operate. So, experiments had to be planned in advance and they had to be conducted by a whole group of people – a single person could not operate the setup alone. And that was what I did not like, since in such a situation you cannot be the master of your time and do experiments whenever you like. Nevertheless, I always eagerly participated in the preparation and conduct of experiments, and became a co-author of my first three scientific papers published in USSR physics journals.

There was also another good experience. These gigantic setups I worked on needed a lot of custom-made parts and components, which were manufactured onsite in a specialised machine shop. By having to oversee this production, I learned how to operate different metalworking machines and how to use them to build various things. This appeared to be very useful in life, as I knew how to make basically everything myself – without having to ask anybody.

Both my parents were biologists. Although they never interfered with my work as a plasma physicist, they always tried to develop my interest in biology, particularly biophysics. I remember how my father was always initiating conversations about nerve electrical impulse propagation, underlying transmembrane ions movements and Hodgkin-Huxley theory, and he encouraged me to read literature about them.

1980 was the year when my father became increasingly more persistent in trying to convince me that this was a good chance for me to combine physics and biology, and to become a membrane biophysicist. His major arguments were, first, that I would become a graduate student of the Department of Membrane Biophysics at the extremely prestigious Moscow Institute of Physics and Technology (MIPT), which had just been created as the experimental base of BIPh, and, second, that I could still be a physicist but simply studying biological phenomena related to bioelectrogenesis.

A visit to BIPh NASU and the interview with Prof. Kostyuk, who was both BIPh director and appointed head of the new MITP department, reassured me that it may be the right thing to do. First, I saw “intracellular dialysis/perfusion” rigs aimed at studying transmembrane ionic currents in isolated nerve cells, and since they could be operated by one or maximum two persons, they corresponded to my inner urge to do experiments independently of others whenever I liked and could. Second, Prof. Kostyuk said that he preferred young associates with a physics rather than biology background. He reasoned that electrophysiology was the kind of science that required building lots of unique electronic equipment (at least at that time), an understanding and modelling of electric phenomena, and if it came to the lack of some knowledge, it was always easier for a physicist to learn and understand biology than for a biologist to learn and understand physics. So, in 1980 I became a graduate in biophysics at the Department of Membrane Biophysics of MIPT, working under the supervision of Prof. P.G. Kostyuk at his Department of General Physiology at BIPh NASU. Sounds complicated, right? But that is how it was. Legally, I was a graduate student of MIPT receiving my fellowship from Moscow, but physically I was working at BIPh NASU in Kyiv.”

Could you tell us what it was like being a PhD student in biophysics in Ukraine in the early 1980s?

“Remember, at that time Ukraine was not an independent country, but one of the republics of the Soviet Union called the Soviet Socialist Republic of Ukraine (SSRU). The Soviet Union was a superpower of those times competing with Western countries in all aspects of life to demonstrate to the rest of the world “the advantages of the communist social system” and to establish its worldwide hegemony. One of the areas of competition was science, and I have to admit that being a scientist in the Soviet Union was quite prestigious, and the salaries of the scientists, especially those at advanced stages of their careers were well above average. Nevertheless, the Soviet Union was a very closed country with its infamous “iron curtain” effectively curtailing any communication with the rest of the world. It meant that the majority of people could not freely travel abroad, and only “chosen” scientists who reached the highest positions and proved to be loyal communist party members could represent the country on an international level. The majority of scientists had no choice but to stay in the country and work to promote their careers, in the hope of sometime reaching the status of being “chosen”. At the same time, the scientific sphere in the USSR as well as all other spheres of Soviet reality (with probably the one exception of the military-industrial complex and scientific branches working on it) suffered from an inefficient economic system, with an inability to provide a sufficient amount of goods and services. This created a quite unique situation in science, where educated and motivated people had to work under conditions of a chronic shortage of everything and had to demonstrate remarkable creativity to advance the research they were doing.

And that was exactly the situation I faced in 1980. Prof. Kostyuk proposed that I should focus on investigating the mechanism of the so called “modification of neuronal voltage-gated calcium channels selectivity by EGTA”. But, he said, all intracellular perfusion setups in the Department were occupied “round the clock, 7 days a week”, and in order to conduct my experiments I would need to build my own. And this meant, he continued, that I had to ask people and look around (including closets) for pieces of equipment, parts and components that were sitting unused, collect them, then build from scratch an electronic amplifier from the most basic elements (resistors, capacitances, operational amplifiers, etc.), put everything together as a functional setup, test it and then proceed with my experiments.

Fortunately, these tasks did not scare me. By mobilising all the skills and experience acquired during my previous tenure at the Institute of Physics in the “do-it-yourself” business, in about 3 months I was ready to do experiments on my own setup (see photograph below). Frankly, this was very useful experience – first, because I perfectly knew how things worked and how they were built; second, I never had a problem with troubleshooting; third, I could always upgrade my setup to meet new experimental needs.

After building my own setup, all that was needed was to use it intensively to generate results. And I had no problem with that, defending my PhD in 1983, just 3 years after admission to the programme. I even published a paper with my results on how calcium ions themselves regulated the selectivity of calcium channels in the Journal of Membrane Biology. Somebody may say “big deal, just one paper in JMB in 3 years”! But those who might say this have no idea what it was like publishing something in the Soviet Union. An “iron curtain” meant not only having no chance to travel abroad, but also the impossibility to publish something in the open press without being granted permission from the “competent authorities”. Many good scientists did not want to go through all this hassle, which is why their research did not receive sufficient attention from the worldwide scientific community. But Prof. Kostyuk was very persistent in persuading his associates to take all possible efforts to publish abroad. And as time showed, this strategy was right because the great achievement of our Institute during those times was to receive international recognition.”

What projects are you working on now?

“In 1991 I left the USSR (to work first in Canada (Dalhousie University) and then in the USA (Georgetown University)), but in 1997 I returned to a completely different country called independent Ukraine. Unfortunately, the disintegration of the Soviet Union and the transition from one big, centrally-controlled, planned economy to many smaller free market economies, but with broken ties, did not bring economic prosperity to the newly independent states (NIS) that comprised the former USSR. Moreover, the economies of these states, and Ukraine was no exception, basically collapsed, with economic hardships negatively impacting all spheres of life, with science probably suffering the most. As the “iron curtain” suddenly came down whilst economies deteriorated, many active former USSR scientists fled their newly independent home countries in search of new opportunities to apply their knowledge and for better economic conditions abroad. So, I appeared in a unique situation: at a time when all my scientific peers were moving to the West, I was moving in the opposite direction back to Ukraine.

Fortunately, the USA and European Union established several research grant programmes specifically aimed at fostering collaboration between scientists from the former Soviet Union and those from the USA and EU countries. The main aim of these programmes was to keep researchers from the former USSR, especially those who were somehow linked with the Soviet military complex, from immigrating to “rogue states”. These programmes did not prevent the “brain drain”, but provided at least some support to those who opted to stay. I got several such collaborative grants, which helped me to continue my scientific carrier in Ukraine and to stay in permanent professional contact with my friends and colleagues abroad.

I was working on a variety of projects, the most important of which included the hormonal and pharmacological regulation of cardiac potassium channels, selectivity, permeation and pharmacology of T-type calcium channels, ion channel involvement in carcinogenesis, and in urinary bladder dysfunction. We are trying to pursue a whole new direction, which we call “X-opto-pharmacology”. But I don’t want to get into any specifics beforehand. Hopefully, you will learn about it from our publications.”

You said that a lot of Ukrainian researchers left the country and are now working abroad. So, what about the next generation of Ukrainian scientists? Are Ukrainian students interested in pursuing scientific career, in particular in biophysics?

“After moving to the USA and Europe during the 1990s and 2000s, many of our former associates brought their electrophysiology and ion channel expertise which they acquired in our Institute to their new places of employment, promoting the Institute’s international reputation. However, in post-independence Ukraine, economic hardships and chronic science underfunding largely deterred and continue to deter young people from pursuing scientific careers. Therefore, there is no adequate replacement by a younger generation of the researchers who left the country, which is why scientific human resources are gradually shrinking. Besides, the younger generation does not show the same motivation, drive and skills for doing science as the previous generation did. The situation can be reversed only by making research activities more attractive in terms of social prestige (at least as it was in the USSR), sufficiently high wages, career growth prospects and a tighter integration into the world and European scientific space. This is quite a complicated issue, requiring reform of the entire scientific sphere in Ukraine.”

Russia’s aggression against Ukraine is the major geopolitical disaster of today. What is your opinion on the situation, how can it be resolved and how do you see the future of Ukrainian science?

“Historically, the people of what is now known as independent Ukraine have not had a straightforward relationship with the state led by Russians, no matter what this state was called – be it Muscovite Tsardom, Russian Empire, USSR or the Russian Federation. These relationships were characterised by a significant degree of superiority of Russians towards Ukrainians, similar to the “younger brother” who is not that smart, speaks a strange language, is not self-sufficient, needs to be controlled and is not to be trusted. It actually led to the denomination of Ukrainians as “small Russians” (‘Malorosy’), as opposed to real or “great Russians” (‘Velikorosy’). But Malorosy could easily convert into Velikorosy simply by forgetting their language and ethnic background – and history is full of such examples. However, most Ukrainians were not happy with such a situation, leading to an almost constant (with some ups and downs) movement for independence, which Russians managed to control, either by combining repression with the activity of a “fifth column” or simply suppression by direct military force.

When the USSR, as a state based on an unviable social system, disintegrated in 1991 many were surprised that it went relatively peacefully. They hoped that the NIS* of the former Soviet Union, among which was Ukraine, would find new forms of collaboration with each other and move towards higher levels of prosperity, while remaining good neighbours. But this group did not include those hardcore Russians with imperialist thinking in the Russian Federation, which became the successor to what was once the USSR. Led by Putin and his clique, they immediately started to hatch plans and make preparations for taking revenge for the defeat of the Soviet Union in the Cold War and to restore not only its boundaries, but potentially its dominance over the former Warsaw Pact countries. And Ukraine became the first and primary target of such policies, which eventually culminated in the current war. The world community should not be fooled by the official appeals of Putin and his clique, who claim a threat from NATO and far-fetched oppression by Ukraine of the Russian-speaking population, as reasons for their “limited military operation”. Their real aim, which they hesitate to proclaim openly because it sounds too Nazi-like, is a “final solution to the Ukrainian question”, which means the elimination of Ukrainian statehood, seizing Ukrainian territory, the extermination or displacement of nationally-conscious Ukrainians, whilst turning the rest back into Malorosy. Thus, Ukraine has no choice but to win this war with the help of the rest of the world, and then to remain strong in order to coexist with such an aggressive neighbour and deter it from further aggressive actions. And good science is an integral component of being strong.

Ukraine and the Ukrainian people are demonstrating an unprecedented resolve and courage in this war in protecting their sovereignty, integrity and independence, which has earned them the well-deserved admiration in the world. However, it comes at the cost of great human and material losses, with the scientific sphere in particular being hit very hard. The scientific infrastructure in the Eastern part of Ukraine is basically ruined, while institutions in other parts of the country are barely functioning because of the threats of air raids, reduced funding and because many researchers simply fled the country. It is difficult to talk about returning to our usual scientific activities before the security situation returns to some kind of normality. But then Ukrainian science will need help to revive itself. And not in the form of position openings or exchanges for Ukrainian researchers to go to Western scientific institutions (further exacerbating the already considerable brain drain), but in the form of grant programmes specifically aimed at involving Ukrainian laboratories in collaborative research with Western partners. A good example was an EU programme called INTAS (International Association for the Promotion of Cooperation with Scientists from the New Independent States of the former Soviet Union), which was established in 1993 to foster collaboration between scientists from the NIS of the former USSR and EU countries. Unfortunately, this programme was closed in 2006, but it may now serve as a template for creating new ones for Ukraine. Various wealthy countries may design similar programmes of their own. This will help Ukrainian science to start again on a new financial and organisational foundation, which will eventually benefit world science. Some steps in this respect have already been taken in Ukraine. Most importantly, the National Research Foundation of Ukraine has been created which, despite some teething problems, is expected to replace the old, Soviet-style, distributive system of science funding with a new competitive one.”

  • The Newly Independent States of the former Soviet Union are Armenia, Azerbaijan, Belarus, Georgia, Kazakhstan, Kyrgyzstan, Moldova, Russia, Tajikistan, Turkmenistan, Ukraine and Uzbekistan.
