 About Me

Passion for electricity has been always present in my life, starting as a preschooler I was already experimenting with toy electric motors. My teenage time was dominated by the construction of high voltage Tesla coils, which finally led me to build a home-made nitrogen laser and the beginning of my adventure in optics. The latter I consider a turning point in my life, from electronics to optics.

When I was finishing my bachelor’s degree, I had experienced a dozen years of home laboratory adventures and my professional area of interests focused predominantly on electrical engineering. Home-made research involved interdisciplinary knowledge: chemistry to deal with photolithography, micro- and industrial electronics to build high voltage equipment, and mechanical engineering to make it reliable. I liked to share my passion for experiments, therefore I organized many scientific presentations. I enabled a group of 800 children to eyewitness 12-foot sparks from my musical Tesla coils in the cinema, in addition to giving multiple shows at schools. I learned how to manage my time, take risks, and ensure safety in extremely dangerous environments, all shown to be of utmost importance in professional research.

Pure electrical engineering was not enough. At that time, I discovered the tandem between electronics and photonics, and so my drift towards optics began. During my master studies I constructed a high voltage nitrogen laser for a university laboratory and demonstrated it at one of the lectures. I finished my degree as number 4 in the “TOP 10” of the department. I realized that my technical skills coupled with my passion for challenges are directly applicable to the laboratory conditions. The potential of the “forgotten gap” – the terahertz part of the electromagnetic spectrum – led me to an optoelectronic laboratory, where I found the application perfect for my interdisciplinary background: terahertz spectroscopy.

Soon after I joined this research group, I was allowed to run experiments by my own. Immediately, I applied a solution known from my Tesla coil electronics to bias a terahertz antenna, which resulted in a journal publication in the Review of Scientific Instruments. The challenging nature of scientific experiments pushed me to go further. My research group works on terahertz spectra of pharmaceuticals, therefore I developed the necessary instrumentation and numerical processing tools to study their thermal stability and similarity. One of my conference abstracts, being a summary of almost two years of work on terahertz chemometrics, was announced to be the Best Student Paper Winner at the leading optical conference – SPIE Photonics West in San Francisco, USA in the terahertz category. I described my discovery of an interesting relation between the terahertz vibrations and physical parameters of drugs that may facilitate their design and select candidates for clinical trials in a more effective way.

In 2015 I was invited to join the spectroscopic group at Princeton University as a visiting graduate student, where I am until now. Daily cooperation with highly motivated members of our research team has prompted me to ask myself fundamental questions about the sources of my motivation and desired goals. Curiosity how things work, coupled with a will to make them better, led me to an idea of application of my spectroscopic experience to support the development of early-stage drugs. I believe that it helps me to explore new research territories and improve the quality of people's life around the globe by minimizing the side effects caused by medicines.

In the summer of 2017 I had an unprecedented opportunity to pursue an internship at NASA Jet Propulsion Laboratory in Pasadena, California, where I worked on the development of interband cascade optical frequency combs. These novel sources of laser radiation are likely to be employed in future space missions for the detection of trace amounts of methane on Mars.
