About me

I am a passionate researcher, dedicated teacher, and inspiring mentor. I have a diverse background spanning multiple fields, including organic and supramolecular chemistry, nanoparticle self-assembly, cryogenic transmission electron microscopy, and extracellular matrix design for breast cancer tissue culture. I am leading a multidisciplinary team of researchers at the interface of materials science and biomedical sciences. We focus on efficiently controlling the structure and properties with the highest possible precision. We develop Lab-on-a-chip-based sustainable in vitro preclinical models for personalized and precision breast cancer disease and diagnostic platforms. We fabricate bio-based short-distance optical fibers and microlasers in the optics and photonics areas. Beyond material development, we are actively engaged in advanced electron microscopy imaging, including cryogenic transmission electron microscopy (Cryo-TEM), electron tomography, and in situ electron microscopy. For more information, see our Research Page and Publications.

More information

About me

In my current role as a postdoctoral researcher in the Precision Nanomaterials Group, I have been working on breast cancer metastasis and developing different 3D culture models to understand how breast cancer initiates and how and why its organ-specific metastasis develops.

In addition to focusing on research, I actively train and supervise students from diverse backgrounds for their bachelor`s (BSc) and master's (MSc) theses.

Field of expertise

I have over 10 years of experience developing 3D in vitro models and microfluidic platforms to identify molecular, mechanical and biochemical changes promoting the formation of breast cancer metastasis using cell, tissue and patient-derived samples.

I use my expertise in in situ contactless rheology to create dynamically responsive soft materials that model breast cancer tissue at both primary sites and secondary metastatic target sites, taking into account not only the genomic events in individual cancer cells but also the composition of the surrounding environment.
