About:

I am a researcher and a lecturer at the Faculty of Mechanical and Power Engineering at Wroclaw University of Science and Technology (WUST). In March 2009 I received my PhD degree with honors by defending a thesis on heat and mass transfer processes in adsorption systems. This gave me the opportunity to work as a post-doctoral research fellow in the United States and in the Netherlands. Currently, I am employed as an Associate Professor in the Department of Thermal Sciences. In September 2020, I was appointed by the Rector of the Wrocław University of Science and Technology to act as the Vice-Dean for General Affairs at the Faculty of Mechanical and Power Engineering, and in September 2024 as Vice-Dean for Cooperation and Science.

Scientific interests:

As a researcher, my work centers on the intersection of thermal and mechanical processes, with a strong emphasis on multiphase flows and processes. I apply this expertise to fields like thermal engineering, power engineering, and refrigeration technology. My current projects focus on investigating low-pressure conditions and exploring how nanoparticles can enhance the thermal and physical properties of working fluids and boiling surfaces.

Formal qualifications:

09.2018 - habilitation (D.Sc.) in the field of technical sciences in the scientific discipline "construction and operation of machines" based on the scientific achievement "Dynamics of heat and mass transfer processes in adsorption systems"
03.2009 - PhD (with honors) awarded by the Scientific Council of the Institute of Thermal Technology and Fluid Mechanics of the Wrocław University of Science and Technology on the basis of the doctoral dissertation "Heat and mass transfer in a chemical heat pump sorption reactor".
07.2003 - Master of Science in the field of "mechanics and machine construction" in the specialty of "process apparatus".

International research/training experience:

10.2012 - 12.2012 - Top 500 Innovators Programme at Stanford University, Palo Alto, CA, USA. The aim of this programme was scientific management and commercialization of research. The training involved entrepreneurial/business aspects of R&D projects, as well as effective communication and dissemination of their outcomes to industrial/business partners and general public.
11.2009 - 09.2010 - Postdoctoral researcher at Stirling Cryogenics, Son en Bruegel (n. Eindhoven), the Netherlands. This postdoctoral stay was a part of international FP6-Mobility Marie Curie Research Training Network Project NESPA (NanoEngineered Superconductors for Power Applications). I was assigned to a WP focused on engineering design and numerical analysis of one-stage and two-stage stirling cryocoolers. The research also aimed at evaluating the possible application of such device to stabilize the operating temperature of several kilometers-long high temperature superconducting cables.
08.2009 - 10.2009 - Postdoctoral researcher at San Diego State University, San Diego, CA, USA. This research project aimed at designing a distribution design of the heat transfer fluid in an adsorption system with multiple adsorbent beds. The training included professional course on 3D engineering and modeling with Solid Works 3D design suite.
07.2005 - 08.2005 - Researcher trainee at RICOH Japan, Research and Development Center, Yokohama, Japan. The focus of this assignment was the development of mechanical dry cleaning method for plastic components. This project included design and construction of a test bench, study of the cleaning element deterioration (at macro-, as well as nano-scale using SEM), and implementation of the proven statistical Design of Experiment (DoE) methodology – the Genichi Taguchi Method.
03.2004 - 05.2004 - Researcher trainee at SINTEF Applied Chemistry, Oslo, Norway. This early stage research training focused on the preparation of synthetic adsorbents (various zeolite structures), conduction of flow-through experiments, and determination of breakthrough curves using spectral analysis.
