Education and research experience
|Present||Assistant professor in Sensory Sciences||FAU Erlangen-Nürnberg, Erlangen, Germany|
|2020||Postdoctoral research associate
|Massachusetts Institute of Technology
|2016||PhD in Molecular Biology and Biomedicine||CIC biomaGUNE, San Sebastian, Spain|
|2010||MSc in Applied Chemistry||University of Zagreb, Zagreb, Croatia|
|2008||BSc and Engineering in Chemistry, Materials and Ecology||University of Zagreb, Zagreb, Croatia|
|2014||Visiting scientist||ZIK HIKE, Greifswald, Germany|
|2014||Marie Curie fellow||INIFTA, La Plata, Argentina|
After her MSc degree in applied chemistry at the University of Zagreb (Croatia), Danijela started her PhD in 2011 at the biomaterials research center biomaGUNE (Spain) with Dr. Moya. Her primary focus was on the design of biocompatible and bioresponsive inorganic interfaces that resemble extracellular matrix. She used these materials to study how chemical, physical, and mechanical properties of the materials govern interactions with cells. Some of her approaches implemented controlled release of bioactive ions from the polymeric surfaces and reliance on bio-inspired substrate coatings. These systems in turn allowed mechanistic studies of cell-surface interactions and determination of constituents promoting cell-substrate interactions.
In 2014 as Marie Curie fellow she visited Prof. Azzaroni’s lab at the INIFTA (Argentina) to apply electrochemical characterization methods in studies of biopolymer coatings used in tissue engineering. Later that year she was invited at the ZIK HIKE (Germany) to work with Prof. Delcea on determination of nanomechanical properties of titania-based implant surfaces with atomic force spectroscopy.
In 2016 she joined the Prof. Anikeeva Bioelectronics Group at MIT (USA) to follow her fascination for neurobiology. Her work was focused on applying the biomaterials engineering to study and modulate the interactions with nervous system. Her favourite piece of work is development of a magnetomechanical neuromodulation technology that allows for nongenetic control of neuronal signalling in the peripheral nervous system. This technology allows for wireless activation of mechanosensory cells leveraging the force (torque) exerted from the magnetic nanodiscs (MND), specifically targeted to the mechanosensitive ion channels
Research Focus Areas
We consider that radical innovations are more likely to be developed within diverse teams that operate by using connective thinking. We are forming a strong multidisciplinary lab from the fields of biophysics, materials science, chemistry, neuroscience, and neurosurgery that comes together at the core of biointerfaces.
Our expertise and interests span from engineering of tools and interfaces for cellular control and elucidating biophysical interfacial mechanisms, to the interrogation of cellular signalling in nervous systems.
We synthetise and functionalize inorganic materials to apply them in studies, aiming to replace or control biological functions.
Main research interests in the biointerfaces lab
We develop materials and technologies that drive exciting biological studies, with emphasis on the control of neurobiological processes. Our focus is to take advantage of externally applied magnetic fields coupled to magnetic nanomaterials to act as force, heat, or voltage transducers for wireless control of sensory cells.
We leverage physical properties of nanomaterials to build biosensors for detection of neurotoxic analytes in vitro and in vivo. Our aim is to design biosensing devices that are fast, miniaturized, and attractive for onsite testing. One of the main advantages of using nanoparticle based biosensing is the small size of the detector, being sensitive in terms of concentration and volume of analyte in respect to conventional sensors.
We are curios in the basic transductory mechanisms in neurons, particularly in the field of mechanobiology. We study physical forces that govern the ion channel activity in primary neurons. Our focus are mechanosensitive ion channels, such as TRPV4 and Piezo1, endogenously expressed in the peripheral neurons and involved in the sensory perception such as touch, hearing, and pain.
Neurotech: Physics and Chemistry of Neuromodulation Technologies
This course seeks to build a foundation of material properties as principles underlying electrical, optical, and magnetic approaches to neural stimulation. Main objective is to introduce students to the interdisciplinary fields involved in development of nanomaterials used for control of cellular signaling in neurobiological systems. Course will start with general introduction to the fundamentals of action potentials and neuronal signaling mediated by ion channels within the nervous system. We will discuss invasive and noninvasive approaches and material requirements to match the biophysical properties of the nervous tissue. Course will then introduce organic and inorganic micro- and nanomaterials for optical, electrical, and magnetic neuromodulation schemes. We will discuss their physical properties, synthetic and engineering approaches considering characteristics that influence signal quality and longevity in the tissues. We will highlight remote technologies conducted by magnetic nanomaterials. Students will be exposed to recent publications that emphasize key advances in the field and learn how various chemical, biological, and engineering concepts and advances are used in synergy to develop state‐of‐the‐art neurotech methods.
