PhD Candidate in Experimental Soft Matter Physics: Protein Assembly for Artificial Meat
1 week geleden
What are you going to do
?M imicking filamentous network structures to exhibit specific physical and sensory properties are desirable for a wide range of applications from meat analogues to artificial tissues for implants. Yet, besides progress in synthesizing or assembling ever more complex bio-inspired structures, manufacturing filamentous plant-protein based structures with rheological and sensory properties of real meat remains a grand challenge, which has not been met to date. Most products in the market consist of , other proteinaceous ingredients, fat and other particles that are glued together into comminuted products. The creation of stronger anisotropic (fibre) structures is key to mimic meat texture and improve juiciness.
Recently, major breakthroughs in designing, visualizing and understanding structure formation and emergent physical properties of (protein) networks have been achieved in Soft Matter science. These breakthroughs allow tuning the structure and mechanical response of colloidal and biological gels and fibrous networks and offer a unified understanding of gelation and yielding. In this project, we will apply this recent progress in Soft Matter Science to design and understand plant-protein based gels for applications in meat analogues.
You will study the structure and structure-property relationship of proteins assembled under various conditions of shear and extrusion, inducing an anisotropic "filamentous" texture. You will create these structures from plant-based proteins, visualize them, and relate the structure to their physical properties. Together with rheology and food experts at Wageningen University (Dr M. Habibi, Prof. A.J. de Goot, Prof. M. Stieger), we will then relate these properties to an overarching physical and sensory understanding of the juiciness of meat analogues.
You will:
Work in the Soft Matter group at the Institute of Physics (IoP) of the UvA, in the group of Prof. Schall, in collaboration with Wageningen University (WUR). Use the infrastructure of the IoP to make, image and characterize the protein network structures using rheology, extrusion, microscopy and (light)scattering techniques. Further access to food-related characterization is available via collaboration with WUR. Be fully integrated in the Soft Matter group at UvA and the consortium with Wageningen University and industrial partners (Unilever, DSM, Rival Foods).Your profile
You have:
A Master degree in Physics, Physical Chemistry or Food Science; Experience in the following fields: Soft Matter, Colloids, Rheology, Protein assembly.You should be able to:
Work at the interface between (Bio-)Physics, Soft Matter and Food Science; Collaborate and adapt in an international team and possess excellent communication skills in oral and written English.Our offer
A temporary contract for 38 hours per week for the duration of 4 years (the initial contract will be for a period of 18 months and after satisfactory evaluation it will be extended for a total duration of 4 years). This should lead to a dissertation (PhD thesis). We will draft an educational plan that includes attendance of courses and (international) meetings. We also expect you to assist in teaching undergraduates and master students.
The gross monthly salary, based on 38 hours per week and dependent on relevant experience, ranges between € 2,,- to € 3,,- (scale P). This does not include 8% holiday allowance and 8,3% year-end allowance. A favourable tax agreement, the '30% ruling', may apply to non-Dutch applicants. The Collective Labour Agreement of Universities of the Netherlands is applicable.
Besides the salary and a vibrant and challenging environment at Science Park we offer you multiple fringe benefits:
holiday hours per year (based on fulltime) and extra holidays between Christmas and 1 January; multiple courses to follow from our Teaching and Learning Centre; a complete educational program for PhD students; multiple courses on topics such as leadership for academic staff; multiple courses on topics such as time management, handling stress and an online learning platform with + different courses; 7 weeks birth leave (partner leave) with % salary; partly paid parental leave; the possibility to set up a workplace at home; a pension at ABP for which UvA pays two third part of the contribution; the possibility to follow courses to learn Dutch; help with housing for a studio or small apartment when you're moving from abroad.Are you curious to read more about our extensive package of secondary employment benefits, take a look here.
