The Particle Flow & Tribology Lab (PFTL) at Carnegie Mellon researches new methodologies to predicting the behavior of granular, powder, and slurry flows in sliding contacts. Our research is conducted through the synergistic use of experiments, physics-based modeling, and computational simulations. The research in the PFTL has application to the semiconductor, energy, biotechnology, nanotechnology, agricultural, space, and defense industries. The lab’s founder and director is Prof. C. Fred Higgs III.


In 2014:
The PFTL is a part of a team that wins an ‘America Makes’ (formerly NAMII) grant to study additive manufacturing.

Randyka Pudjoprawoto successfully defends his PhD thesis in powder and transfer film lubrication.

Profs. Higgs (along with Drs. LeDuc and Mpagazehe) were awarded the NSF I-Corps award for university start-up activity related to bio-energy/biofuels.

In 2013:
Martin Marinack and Jeremiah Mpagazehe successfully defend their PhD theses in granular flow tribology and slurry/multiphase flows & tribology, respectively.

The PFTL is awarded grants from three global companies (Timken , Sanitarium, and Westinghouse House Electric Companies).

The PFTL is awarded research translation grants from Innovation Works and CTTEC to study algae bio-energy.

Jeremiah Mpagazehe wins the STLE Young Tribologist award.

In 2012:
Prof. Higgs and wife welcomes future tribologist prospect Cecil Fred Higgs, IV into the world.

Prof. Higgs is co-awarded the 2012 Benjamin Richard Teare Teaching Award (for faculty member within the Carnegie Mellon College of Engineering in recognition of excellence in engineering education.)
