Analytical Chemistry / Nanoparticle characterization

My journey at HIMS started in 2013 as a visiting researcher. I returned in 2015 as a post-doc and have been appointed assistant professor in 2019. I am an analytical chemist with a background in the characterization and environmental fate of carbon nanoparticles. My research is focused on two fields which I am most passionate about, art conservation and the environment, especially how carbon-nanocages, nano/micro-plastics, and associated chemicals impact our ecosystem, health, and society. I work in multidisciplinary teams, including chemists, physicists, biochemists, computational chemists, humanities researchers, eco-toxicologists, environmental scientists, polymer chemists, artists and conservators. I am also passionate about teaching and education. I am a teacher and coordinator of the analytical sciences track of the UvA-VU joint MSc chemistry program.

Faculty of Science

Van 't Hoff Institute for Molecular Sciences

In 2024, I joined HIMS as tenure track assistant professor in the Homogeneous, Supramolecular and Bio-Inspired Catalysis group, contributing to the Research Priority Area of ‘Sustainable Chemistry’. My research bridges (photo)reactions in porous materials and inventive spectroscopy.  The idea is that this ‘nano-confinement’ will reduce interaction pathlengths, thus enhancing the conversion rate of photoreactions that depend on short-lived excited species. My research will focus on heterogenous photoredox chemistry in metal-organic and covalent-organic frameworks. I combine these photoactive materials with (fast) spectroscopic techniques (UV-vis, IR, X-rays) to study how spatial confinement influences catalytic activity and selectivity, thereby advancing sustainable chemical processes. As these studies often require new analytical tools and test stations that are developed, built and tested in our group.

Synthesis & Catalysis / Material characterization

I moved to HIMS as an assistant professor in 2017 to study the activity of catalysts in sustainable processes by Nuclear Magnetic Resonance (NMR) both experimentally and theoretically. Personally, I am still intrigued by metal-ligand bond interactions of organometallic compounds and their theoretical description by ab initio and DFT methods. My research focuses on exploring the reaction pathways of highly reactive, transient species stabilized by transition metals with applications in homogenous catalysis. Furthermore, I am appointed as a visiting professor in the Department of Chemistry at the University of Johannesburg.

Analytical Chemistry

In January 2019 I started my tenure track at HIMS as an assistant professor in Analytical Chemistry. My research focuses on the development of advanced separation science and mass spectrometry to characterize protein systems (e.g. enzymes) and synthetic polymers (e.g. biodegradable polymers). I use these technologies to characterize the molecular structures and distributions that are responsible for characteristic properties of the macromolecules (e.g. activity, stability). I was awarded the Ernst-Bayer Award in 2014 and the Csaba Horváth Young-Scientist Award in 2015. In October 2018 the Analytical Scientist magazine listed me among the 'Fab Forty' of gifted young scientists 'making waves in analytical science.'

Computational Chemistry/Biocatalysis

I joined HIMS in 2022 as Tenure Track Assistant Professor in Chemistry of Biomolecular Systems. I am a member of the Computational Chemistry group and my research focuses on multiscale simulations of biomolecular systems. In particular,  we design coarse-grained models able to reproduce the intrinsic flexibility of nanoparticles (NPs) and use atomistic simulations combined with rational design to develop ligands for the NPs. With a recent grant awarded by the Synapsis Foundation, we design and validate agents (e.g. peptides, proteins) to modulate the activity of proteins associated with neurodegenerative diseases.

Dr R.M. (René) Williams

Molecular Photonics

The interaction of light and matter is the basis of our research. We focus on light activated (hybrid) nanomaterials for energy and health. We develop and study new materials for thin film solar cells (doped methylammonium-free perovskites) as well as new photoactive systems for medical applications (photodynamic therapy and photo-antiseptic materials, activated by NIR light). Photoinduced electron transfer, energy transfer and triplet state formation in molecular-, supramolecular- and nanosystems are key processes. I have participated in the SUSANA and UNINANOCUPS EC networks, was supported by the Vietnamese Overseas Scholarship Program, and am currently involved in a H2020 ITN/EJD. After accomplishing an MSc and a PhD at the UvA, I returned to my Alma Mater in 1999.
