The Peptide Self-Assembly (PSA) Conference in Mainz this August was a great chance to discuss science. Well-organized program hosted at @mpi_polymer. #Chemistry psacon2026.com/
#ECC10 in Antwerp felt like a reunion: reconnecting with @YoungChemists, @IntlYoungerChem, and chemists from across the globe, celebrating EYCN's 20th anniversary, and sharing our work on peptide self assembly. @BeKvcv @EuChemS_Congres @EuChemS
PepMat2026 in Warsaw: advancing peptide materials science. Three days of plenaries and talks on self-assembly, amyloids, and biomaterials. @ChemistryUW #PeptideMaterials
Earlier this month at the @GlobalYAcademy Annual Conference in Bremen: young scientists worldwide tackling "Machine Intelligence for Society," an opening by @ISC President-elect Robbert Dijkgraaf, and a dialogue on AI and the future of open research. @Joao_F_Borges @chemFunMan
Last week at the @AvHStiftung Annual Meeting in Berlin: 670+ researchers from 70+ countries, a keynote by Nobel Laureate Benjamin List, and a reception with Federal President Steinmeier at the Humboldt Forum. #AvHConnectedForImpact
Our QSense Omni QCM-D from @BiolinSci was delivered to the John Lab @CU_Bremen – a major addition to our wet laboratory, supporting our work on biomolecular interactions, lipid membranes, and peptide-membrane studies. Thanks to @LOT_QD for installation. #PhysicalChemistry

2025 was the first year of our research group at @constructor_uni Bremen. Grateful for the dedication of our first PhD student and technician, as we advance work on biomolecular self-assembly and interfaces. Excited for 2026!
New review (doi.org/10.1002/smll.2025108…) in Small on functional DNA and RNA conjugates. We discuss strategies for synthesizing and purifying nucleic acid bioconjugates, with relevance for biomaterials, nanotechnology, and RNA therapeutics. @AdvPortfolio with @WeilTanja, @Lab_DavidNg
New @angew_chem paper on how co-assembling peptide fibrils can enhance or reduce catalytic activity. MD simulations and AF3 modelling helped explore substrate binding behaviour, and co-assembly interfaces. doi.org/10.1002/anie.2025111…

„Mit der #HightechAgendaDeutschland investiert 🇩🇪 strategisch in Schlüsseltechnologien, um technolog. Führungsfähigkeit, Wohlstand & Souveränität zu sichern“, macht BM @DoroBaer auf dem diesjährigen @Falling_Walls-Summit deutlich. Wir wollen & wir können Hightech-Republik sein!🦾
Inspiring days at the @Falling_Walls Science Summit 2025 in Berlin. From Alzheimer’s research to autonomous labs and science diplomacy, I joined scientists, policymakers, and innovators discussing the question: Which are the next walls to fall?
Inspiring exchange at the German-Israeli Young Scientists Evening at @bbaw_de🇩🇪🇮🇱, celebrating 60 years of binational scientific collaboration. Great talks, lively discussions, and genuine curiosity across disciplines. Thanks to @ScienceAbroad and @GifResearch.
Attended the @SupraLife_EU Final International Conference in Aveiro 🇵🇹, where I gave a talk on "Molecular Mechanisms of Peptide Assembly for Biomaterials". Great discussions on supramolecular materials and nice to meet colleagues and friends again!

I am looking forward to welcoming Aiswarya Rajeev as the first PhD student in my group at @constructor_uni. She will work on peptide self-assembly and membrane interactions, contributing to our research in biophysical chemistry and bionanomaterials.
We're thrilled to announce that Ms. Aiswarya Rajeev, a talented alumna of the University of Hyderabad's Integrated Chemistry program (2019-2024), has been awarded a prestigious PhD scholarship at Constructor University in Bremen, Germany. Under the guidance of Prof. Dr. Torsten John, Aiswarya will embark on a three-year doctoral program focusing on Biophysical Chemistry, Biomolecular Self-assembly, and Bionanomaterials.
Aiswarya's research explores the self-assembly of fibril-forming peptide sequences, investigating their interactions with membranes and peptide-cell interactions. This work has potential applications in:
- Drug Delivery: Developing innovative methods for targeted drug delivery
- Biosensing: Creating sensitive biosensors for disease detection
- Biomaterials Design: Designing novel biomaterials for various applications
Aiswarya's academic journey includes:
- Master's Thesis: "The Effects of Molecular Crowding on the Membranolytic Activity of DSP Proteins" under Prof. M. J. Swamy at UoH
- Summer Research Fellowship: IISER Pune, working on Porphyrin Chemistry under Prof. V. G. Anand
Aiswarya expresses her heartfelt gratitude to Prof. M. J. Swamy: For constant support and guidance; Dr. T. Saravanan and Dr. Jovan Jose: For invaluable recommendations and inputs and the University of Hyderabad: For providing an excellent academic environment and opportunities.
We congratulate Aiswarya on this remarkable achievement and wish her continued success in her future endeavours!

Feeling awed and a bit starstruck that @ScienceMagazine decided to run a book review on #LabworkToLeadership!!
Thank you to @JonathanLWai for authoring the review! science.org/doi/10.1126/scie…
