Oleksandr came to the US from Ukraine. He was born in the city of Dnepropetrovsk, which is one of the biggest industrial cities of the country. After one year of living in noise and industrial fumes with a little baby (that was him), his parents decided to move to the more quiet and picturesque city of Cherkassy, where he grew up and went to school.

In 2000, after graduating from High School, Oleksandr went to Kiev, the capitol of Ukraine - in his opinion, the most beautiful city in the world - where he entered the Chemistry Department of Taras Shevchenko University. During his undergraduate years, he was involved in research on semiconductor gas sensors based on tin dioxide.

In parallel with classes and research, he tutored students of the Physical-and-Mathematical Lyceum in Chemistry. This lyceum is a High School institution associated with Taras Shevchenko University.

While in the Borguet Group, Oleksandr was involved in the ultrafast laser spectroscopy of interfaces.  As a part of his doctoral thesis work, he developed a novel type of ultrabroadband infrared laser sources based on noncollinear optical parametric amplifier (NOPA) technology.  These lasers produced infrared pulses that have enough bandwidth to cover, such as the entire spectrum of the hydrogen bonded and non-H-bonded hydroxyl vibrations in water molecular systems.  Oleksandr applied his NOPA to the broadband nonlinear optical spectroscopy of water-mineral interfaces. His studies, for instance, helped detect certain hydrophobic properties of silicon dioxide surfaces that would not be expected based on the wide prior knowledge of predominant hydrophobic nature of hydroxylated silica.

After graduation, Oleksandr joined Quantronix Corporation, which was later merged with its sister company, Continuum Electro-Optics.  Later on, Oleksandr moved to Los Alamos National Laboratory where he carried out research in the ultrafast nonlinear optics and spectroscopy of semiconductor nanomaterials (e.g. quantum dots).

In 2016, he joined IPG Photonics in the San Francisco Bay Area as R&D Scientist.
