The Peter Jost Tribology Award is a new award, established in 2020 by the ITC to honor the late Prof. H. Peter Jost, the “founding father” of modern-day tribology.

For her fundamental interfacial studies of fluid lubrication mechanisms across all regimes, from boundary and elastohydrodynamic to hydrodynamic, at length scales from nanometers to micrometers under both steady-state and transient conditions over a wide range of temperature, Dr. Juliette Cayer-Barrioz, CNRS Director of Research of the Laboratory of Tribology and System Dynamics (LTDS), Ecole centrale de Lyon, France is awarded the 2025 Peter Jost Award in Tribology.

Le Prix Peter Jost de Tribologie est un nouveau prix, créé en 2020 par l’ITC en hommage au regretté professeur H. Peter Jost, « père fondateur » de la tribologie moderne. Pour ses études fondamentales des mécanismes de lubrification des contacts dans tous les régimes, de la limite et de l’élastohydrodynamique à l’hydrodynamique, à des échelles de longueur allant du nanomètre au micromètre, en régime permanent et transitoire sur une large plage de températures, le Dr Juliette Cayer-Barrioz, directrice de recherche CNRS du Laboratoire de Tribologie et Dynamique des Systèmes (LTDS), École centrale de Lyon, France, reçoit le Prix Peter Jost de Tribologie 2025.

Félicitations à Juliette Cayer-Barrioz pour cette nomination prestigieuse !

La cérémonie de remise de prix aura lieu lors du WTC2026 à Rio et Juliette Cayer-Barrioz présentera ses travaux de recherche à l’occasion d’une conférence plénière.

Eligibility

Individuals who are nominated for the Peter Jost Tribology Award shall have made sustained and substantial contributions to the science or technology (including industrial practice) of tribology. This Award is intended for mid-career tribologists—typically below the age of 50. The Executive Committee members of ITC are not eligible for nomination, nominating an award candidate, or writing support letters.

Nomination Procedure

Candidates can be nominated by peers (except for those indicated under Eligibility) who are knowledgeable and qualified to corroborate the key accomplishments of those candidates being nominated. A nominator can only nominate one individual per year and must also obtain three support letters as part of the nomination package. The ITC Executive Committee will collect and evaluate all eligible nominations in making the final selection of award winners.

The Nomination Package 

1. Nomination Letter: The nomination letter must provide the details of the key accomplishments of the nominee in chronological order emphasizing, in particular, the significance and importance of his/her work in terms of solving a long-enduring problem or advancing the frontiers of tribology with breakthrough discoveries and/or industrial applications. From the narrative, the significance of these accomplishments must be very clear and evidenced by e.g., high-impact publications, industrial innovation, patents, invited presentations, awards/honours, and commercial developments. The nominator may choose to document in detail (in an appendix consisting of additional support materials) the most important tribological discovery/industrial contribution of the nominee for which he/she should be considered the most for the award. Most often, there are multiple participants in highly significant works and discoveries; hence, the specific contribution of the nominee must be delineated in the nomination letter. In a concluding sentence or citation, the nominator must provide a one-sentence quote that represents nominee’s most outstanding contribution to the field and/or his/her true accomplishment for which the Peter Jost Tribology Award should be considered.  The nomination letter should be very concise, self-consistent, and no more than 2 pages long, but should have the most important points that Award Committee will need to make the final determination.
2. Support Letters: The nomination package should include three additional support letters and these should be arranged by the nominator. One of these support letters can be from the same institution or country where the candidate resides. However, two of the letters must be from peers of international standing from another country, who are also very familiar with candidate’s seminal work. These letters should not exceed one page (as they are meant to further attest and emphasize the key accomplishments of the nominee) and must be arranged from peers of which at least two are from other countries than the candidate.
3. Curriculum Vitae: the nominator must also include a CV or resume, not exceeding five pages, which includes the nominee’s list of patents, industrial impact, key publications and key presentations.

 Judging Criteria

1. The nominee will typically be below the age of 50 on 1st January of the award year.
2. The nominee must have demonstrated a notable contribution to the field of tribology including demonstration of significant achievement reflected by high-impact publications (e.g., peer-reviewed journal articles, invited review papers, books, etc.) and/or a significant impact within industry or commercial field (e.g., development of a novel process or product, patent or contribution to a significant economic / environmental improvement). The nominee may also demonstrate a track record which may include other awards or honours, invited presentations, etc.
3. The nominee may additionally have demonstrated evidence of strong leadership qualities as reflected by teaching, mentoring, or management record in tribology as well as voluntary services to events and/or professional organizations that promote tribology.
