PhD (M/F) in Manufacturing processes of biosourced foams

Scientific Context and Objectives

This PhD project focuses on the development of continuous manufacturing processes for biobased foams with controlled structure, addressing the challenge of replacing petro-based materials in a context of resource scarcity and recycling constraints. Biobased foams are increasingly relevant in sectors such as packaging, insulation, and lightweight materials due to their environmental benefits (biodegradability, low carbon footprint) and economic advantages (renewable resources).

The objective is to optimize foaming, stabilization, and solidification processes to prevent structural collapse and ensure reproducible, high-performance materials. The project will explore the relationship between formulation, flow dynamics, and final foam properties, combining soft matter physics and process engineering.

Research Program

The PhD candidate will:

• Optimize formulations using biopolymers (e.g., pectin, cellulose) to stabilize gas-liquid interfaces and enhance foam structure.
• Develop and characterize processes from microfluidic to pilot scales, using real-time imaging and rheological analysis.
• Correlate gelation kinetics, solidification, and mechanical properties to enable industrial-scale production.
• Collaborate with interdisciplinary teams and leverage advanced experimental platforms at the Rheology and Processes Laboratory (LRP, CNRS/Grenoble INP).

Profile and Required Skills

Master’s degree or engineering diploma (Bac+5) in Process Engineering, Soft Matter Physics, or related fields. Strong experimental skills and interest in hands-on research. Background in physico-chemistry, formulation, or microfluidics is advantageous. Upper-intermediate English proficiency (written and oral) for scientific communication.

Working Environment

• Facilities: Access to microfluidic platforms, rheometry, and advanced imaging at LRP.
• Collaborations: Partnerships with CERMAV, Centre Technique du Papier (CTP), and national/international research groups (Carnot Polynat, Labex TEC 21).
• Supervision: Regular meetings with a multidisciplinary team of three advisors and external thesis committee.
• Opportunities: Participation in international conferences, publications in high-impact journals, and potential patent filings.
