Research Interests

Sustainable manufacturing is one of the engineering grand challenges of the 21st century.

The Szekely Group focuses on sustainable separations through the synergistic combination of materials science and chemical engineering. Sustainable production of chemicals, pharmaceuticals, and clean water is largely impacted by the efficiency of separation processes in product supply chains. The conventional separation processes can account for as much as 80% of the total manufacturing costs, contributing ~10% of the world’s energy consumption.

In particular, the group’s research investigates the potential of dmembranes and molecular imprinting for efficient purification of (bio)pharmaceuticals and water using advanced materials such as metal-organic frameworks, graphene, imprinted polymers, polymers of intrinsic microporosity.

  • Molecular-level separations, in particular adsorbents and membranes
  • Machine learning for prediction of separation performance and inverse design of separation materials
  • Molecular imprinting for selective separations
  • Nanofiltration at both membrane fabrication and process development level
  • Catalytic membrane reactors
  • Green process engineering
  • Hybrid processes
  • Downstream processing of (bio)pharmaceuticals
  • Environmental clean-up
  • Wastewater treatment
