Tobias Benselfelt

KTH Royal Institute of Technology is seeking a postdoctoral researcher to join a multidisciplinary team focused on adaptive separation in cellulose-based, porous monoliths. The project, led by Assistant Professor Tobias Benselfelt and Professor Mahiar Hamedi, aims to develop innovative materials for biopharma separation, particularly targeting large particles such as lipid nanoparticles. Research will involve designing and characterizing materials with and without electrochemical control over pore-wall properties, integrating these materials into chromatographic columns, and testing their performance with model and real samples. The research group operates at the intersection of materials science, chemistry, and biotechnology, with a strong emphasis on electrochemistry, membrane technology, and tunable molecular separation. The project offers opportunities for fundamental and applied research, with potential for commercial innovation. The group values diversity, equal opportunity, and entrepreneurial spirit, and provides a creative, dynamic environment with excellent working conditions and benefits. Applicants should hold a recent doctoral degree (within the last three years) in a relevant field such as physical chemistry, materials science, or biotechnology. Proficiency in English and strong communication skills are required. Experience with membrane or chromatographic separation technologies, electrochemistry, or electroactive materials is advantageous. Candidates should be motivated, independent, collaborative, and proactive, with a commitment to diversity and gender equality. The position is a full-time, two-year appointment with a monthly salary. The application deadline is January 15, 2026. To apply, submit a CV, diplomas and grades, a personal motivation statement, and two relevant publications through KTH's recruitment system. For more information, contact Assistant Professor Tobias Benselfelt at bense@kth.se. Keywords: cellulose fibres, porous materials, electrochemistry, adaptive separation, chromatography, materials science, biotechnology, membranes.

KTH Royal Institute of Technology invites applications for a two-year postdoctoral position focused on adaptive separation in cellulose-based, macroporous monoliths. This research aims to address key challenges in biopharma separation, particularly for large particles such as lipid nanoparticles. The successful candidate will design and develop materials with and without electrochemical control over pore-wall properties, integrate these materials into chromatographic columns, and evaluate their performance using both model systems and relevant particle samples. The postdoc will work closely with Assistant Professor Tobias Benselfelt, Professor Mahiar Hamedi, and a multidisciplinary team specializing in tunable membranes and adaptive separation using cellulose fibrils and fibres. The group’s research spans fundamental physics and chemistry to applied electronics, providing a dynamic and collaborative environment. The project offers opportunities for both fundamental and applied research, with potential for commercialisation. Applicants must have a doctoral degree (or equivalent foreign degree) completed by the time of employment. Proficiency in English and strong communication skills are required. Preferred qualifications include backgrounds in physical chemistry, materials science, or biotechnology, as well as experience with membrane or chromatographic separation technologies and electrochemistry. The doctoral degree should have been obtained within the last three years prior to the application deadline. Candidates should demonstrate curiosity, motivation, independence, and strong research expertise, as well as a collaborative and proactive approach. Awareness of diversity and equal opportunity issues, especially gender equality, is valued. The position is full-time, temporary (up to two years), and based in Stockholm, Sweden. KTH offers attractive benefits, good working conditions, and a creative, international research environment. The application deadline is January 15, 2026. For further information, contact Assistant Professor Tobias Benselfelt at bense@kth.se. To apply, submit your application via the KTH recruitment system, including a CV, diplomas and grades (with translations if necessary), a one-page motivation statement, and two papers demonstrating your qualifications. Ensure your application is complete and submitted by the deadline.

Join KTH Royal Institute of Technology as a postdoctoral researcher in the ERC-funded DynanoNet project, working on electronically tunable membranes for digitally controlled separation. This position is based at the Department of Fibre and Polymer Technology, within the Fibre Processes and Technology division in Stockholm, Sweden. The project aims to develop a new class of cellulose-based membranes with electronically controlled properties, enabling adaptive and digitally controlled separation processes. The research is led by Assistant Professor Tobias Benselfelt and is embedded in a strong interdisciplinary environment that combines fundamental science, advanced materials research, and collaboration with industry and research partners. The postdoctoral role involves independent research in the project area, coordination of experimental work with a PhD student, presentation of results at project meetings, workshops, and international conferences, and maintenance of project documentation and reporting. The successful candidate may also contribute to the supervision and mentoring of PhD and master’s students. Applicants must hold a doctoral degree in materials science, chemical engineering, polymer science, electrochemistry, membrane science, or a related field by the time the employment decision is made. Excellent English communication skills are required. The ideal candidate will also have a recent PhD or equivalent degree, research experience in membrane science, electrochemistry, transport phenomena, nanofibrillar materials, cellulose nanofibrils, hydrogels, or filtration technologies, and practical experience with electrochemical techniques such as impedance spectroscopy, cyclic voltammetry, or chronoamperometry. Experience with experimental design and device construction, plus a strong publication record, will be viewed positively. The position is a temporary full-time appointment for up to three years. The project is ERC-funded, and the role offers a monthly salary. KTH emphasizes sustainability, equality, diversity, and strong academic development opportunities in a creative and dynamic environment. Applications must be submitted through KTH's recruitment system. The application should include a CV, a Google Scholar or similar profile link, degree documents and transcripts, translated documents if needed, a one-page research motivation statement, and two papers demonstrating relevant expertise. The deadline is 2026-09-01.
