Bio

I have 7 years of experience in the scientific group. I was focused on improving the metrology throughput in the nanoscale. I have built my own atomic force microscope with a haptic interface that lets humans “feel” the interatomic interactions on their own hands and poke the atoms with light (i.e., using photon pressure). I have worked in multidisciplinary teams and led a few research projects.

I specialize in the measurement circuits prototyping. I design custom analog/digital circuits and have hands-on experience with laboratory equipment and measurement techniques. The AFM is a complex device consisting of multiple electronic circuits. The final outcome is the result of an extensive set of physics rules taking part. This enforced my incisive approach to understand the principle of operation of the device before making assumptions.

I am an analytical & critical thinker, inquisitive and curious about the world. Enthusiastic to travelling, conferences, fairs and internships.

Scientific experience

My focus is mainly on metrology in micro- and nanoscale with the use of electrical and optical techniques. Most of my experiments were performed with the use of self-made both electronic circuits and mechanical parts.

Metrology in SPM

I was invovled in the development of new measurement techniques, including calibration and reference methods, especially force and deflection. Our investigations covered the uncertainites and resolution of the measurements by the means of Scanning Probe Microscopy. None of the SPM manufacturers provide the exact measurement capabilities of any commercial microscope. They are usually calibrated with the use of the calibration grade structures. In opposition, a self-designed AFM can be fully described and traced to SI-units.
I was a coinvestigator in seven scientific and business-related grants, e.g. NCN Opus, NCBR Szybka Ścieżka, NCBR Lider and took part in short-term placement at École Polytechnique (France).

Used techniques

  • Scanning Probe Microscopy, especially Atomic Force Microscopy
  • Scanning Electron Microscopy, structure modifications with Focused Ion Beam (SEM/FIB dual system)
  • Optical measurements using optical fibers and Optical Beam Deflection (OBD)
  • Interferometry and laser vibrometry
  • Metrology and measurement references with the use of MEMS and NEMS structures

Haptics in SPM

Feel the interatomic interactions directly on your hand in real time.

My PhD thesis was devoted to haptics applied to microscopy. Haptics means "by the sense of touch". Nowadays magnification is ain't no more a problem, though the structures (e.g. nanowires, quantuum dots, FinFETs) becomes too small to be handled easily. My haptic system provides alternative for classic raster AFM scan and allows the user to find it with his own hand.


Other scientific topics covered

  • MEMS actuation methods & control techniques
  • Optomechanical studies, photon pressure used as a force (also as a force reference)
  • Ink jet and aerosol printed metal
  • 2D materials characterization (e.g. MoSe2 suspended membranes)
  • Thin film solar cells
  • Non-raster scanning and custom control algorithms

I presented my experiment results at Polish and international conferences. I gave classes and lectures dedicated to microscopy, digital, and analog circuits. Most of my work was performed in cross-functional teams, often in cooperation with people of different specializations at different educational levels.
