Brief Summary of research:
One of my main research fields is the exploration of reliability challenges in advanced semiconductor process nodes. The shrinking dimensions of advanced semiconductor process nodes to nanometric scales introduce significant reliability challenges related to the aging of integrated circuits. This aging process results not only in performance degradation but also in incorrect functionality over the lifetime of the circuits. In my research, I focus on transistor aging, which represents the physical deterioration process that occurs over a transistor's lifetime. Two physical mechanisms govern transistor aging: Hot Carrier Injection (HCI) and Bias Temperature Instability (BTI). HCI occurs when high kinetic energy carriers flow through a transistor, whereas BTI occurs when a static voltage (logical state) is applied to the gate of a transistor without current flow for an extended period, typically ranging from tens of seconds to several weeks. Both BTI and HCI increase the transistor threshold voltage, which in turn increases the switching delay. As part of my research, I have introduced new micro-architectural and physical design flow solutions to mitigate these challenging phenomena. The mitigation techniques are based on a preventive maintenance approach that monitors chip degradation over its lifetime and activates preventive measures when necessary.

Brief Summary of research:
The research focuses on the measurement of heat flow, or thermal transport, in low-dimensional materials. Low-dimensional materials, like 2D atomic layers such as graphene, or 1D channels such as carbon nanotubes, have a wide variety of physical behaviors of fundamental interest and with promise for future applications in efficient nanoelectronics, flexible electronics, high-performance thermoelectrics, quantum sensing, and more. Thermal transport can reveal many exotic phenomena since it is sensitive to any emergent degree of freedom regardless of electrical charge. Heat is also one of the key bottlenecks for modern processor performance, leading to frequency throttling and safety issues, but measuring the electronic heat generated in nanoscale devices is a long-standing challenge.
Specific research topics related to Nanoscience and Nanotechnology:
I developed a new kind of thermal transport measurement called nonlocal noise thermometry with graphene thermometers. Using high-bandwidth microwave-frequency measurements of electronic noise, the electronic temperature of graphene can be measured. By placing multiple contacts along a specific geometry, and measuring the nonlocal noise at different pairs of terminals with a novel differential noise measurement circuit, we can measure the temperature at different locations in a multiterminal device. Using the ability of graphene to easily interface easily with many low-dimensional materials, I used this to measure electronic thermal transport properties of 2D hydrodynamic electrons, 1D electrons in carbon nanotubes, and even 0D, localized electron heat transport. Furthermore, I showed that this approach is sensitive to the heat carried in insulating materials, like spin waves in a 2D magnetic insulator, and neutral modes of a 3D spin liquid candidate material. My research depends on high-quality nanofabrication, which is crucial to the creation of these low-dimensional material-based devices. Typical processes include reactive ion etching, electron beam lithography, and thermal evaporation, as well as photolithography and sputtering.

Non-viral vectors, which are essentially DNA-containing nanoparticles, can be retargeted by incorporating ligands into their lipid or protein shells, but to date there are no convincing studies to demonstrate the in vivo utility of retargeted non-viral vectors.
We aim to develop a non-viral gene delivery encoding antioxidant genes and/or peptides that inhibit production of ROS, to drive the expression in the main cell type responsible for the generation of ROS.

Genetically Encoded Nanoparticles
Specific research topics related to Nanoscience and Nanotechnology:
The multifunctional nature of nanoparticles offers groundbreaking opportunities in healthcare and biological research, spanning applications such as tumor imaging, radiotherapy, hyperthermia, and radiation resistance. However, their potential is impeded within living organisms due to the intricate challenge of precise delivery to target tissues or cells, often leading to off-target effects. Our innovative approach capitalizes on the genetic machinery of cells to engineer genetically-encoded nanoparticles (GENPs). Through the expression of metal-producing genes, we synthesize intracellular metal nanoparticles, including gold and silver, ensuring GENPs exhibit targeting capabilities at the cell and tissue of interest and at the desired time. This technology has the potential to revolutionize biomedical therapy and imaging, offering transformative solutions across diseases like cancer and neurodegeneration. In doing so, we bridge the gap between the promise of nanoparticles and their practical utility in healthcare and biological research.

Brief Summary of research:
Ubiquitin (Ub) and ubiquitin-like proteins (UBLs) are involved in a wide range of cellular processes including protein degradation, cell signaling, transcriptional regulation and the DNA damage response. The regulation of numerous cellular processes by these proteins is ascribed to their ability to perform a wide spectrum of modifications. To date, besides ubiquitin, which can modify a target protein with mono or poly-ubiquitin chains with various linkages of varying length, more than a dozen different UBLs are encoded in the human genome, thereby significantly increasing the repertoire of ubiquitin modifications. Not surprisingly, improper regulation of these modifications has been observed in many human diseases including cancer, Alzheimer’s disease, Parkinson’s disease and viral infections. My lab is interested in the molecular mechanisms governing Ub and UBL conjugation to cellular proteins.
Specific research topics related to Nanoscience and Nanotechnology:

Brief Summary of research:
Our lab investigates the response of the body to fasting. The liver is responsible for supplying the body with fuel (glucose and ketone bodies). During fasting, a set of responses are triggered within the liver in order to maintain the supply of energy to the body. This chain of reactions is made possible by thousands of genes being turned “on” and “off”. If these reactions are not regulated, we are unable to survive fasting for more than a few hours. Conversely, if the liver produces too much fuel, this can lead to the development of diseases such as diabetes, at the root of which lies the excess unregulated production of glucose. Using genomic, metabolic and molecular biology approaches, we study the gene regulatory networks that mediate the liver’s response to fasting. We aim to better understand these networks and how their dysregulation can contribute to obesity and diabetes.

One of the major focuses in the lab is understanding how cells maintain their “healthy” and complex protein structures during increased oxidation, which is one of the main hallmarks of aging and age-related diseases (e.g., Alzheimer, Parkinson and others). Our overarching goal is to develop a novel technology that will enable us to unravel the mystery of the cellular “redox code” and the way it defines cells and their aging process. To achieve this goal, we utilize and develop an extensive toolbox of technologies which able to quantify changes on cellular and molecular levels. For example, we have developed fluorescence-based sensors, expressed inside cells at different organelles to monitor and quantify precise changes in intracellular oxidation. This allows us to study redox-dependent heterogeneity on a single cell level as well as isolate a subset of cells with pre-defined cellular oxidation for investigation of its proteome and redox-dependent regulation.

Brief Summary of research:
I am fascinated by volcanoes, diamonds and pink granites*. Perhaps this is why I am interested in the role of water and other volatiles in magmatic processes. Volatiles are involved in most igneous processes. They are central in formation of melts, play a major role in transporting trace elements and radio-isotopes between mantle reservoirs or between mantle and crust, and are the driving force of explosive volcanic eruptions.

Brief Summary of research:
I am marine biogeochemist and I am studying the bioavailability of iron to marine phytoplankton & the interactions between phytoplankton in the ocean and their chemical environment. In the last years we have been investigating an important colony forming marine cyanobacterium, which we discovered employ many unique pathways to capture particles and aerosols and utilize them as a nutrient source. Our studies focus on microbe-mineral interactions, trying to untangle the molecules and pathways involved in particle attachment and translocation along the colony filaments, communication and dissolution of minerals.
With regards to the nano-center, we frequently analyze minerals and cell-mineral interactions with SEM, SEM-EDS, XRD, XRF as well as Nano-SIMS, MALDI and Synchrotron (aboard).

Desert dust is an important source of the nutrients iron (Fe), phosphorus (P), and nitrogen (N) to remote ocean regions, supporting phytoplankton growth and carbon cycling. Desertification induced by global climate change is expected to increase dust fluxes to the ocean. Elucidating the ability of phytoplankton to utilize nutrients from dust, an integrative line of research we have been advancing over the last 12 years, will assist in predicting the function of the ocean as a life-supporting system in the global change era.
Studying natural Trichodesmium colonies from the Gulf of Aqaba, we discovered unique adaptive mechanisms for capturing and storing dust particles within the colony core, enabling efficient utilization of Fe (and P) from dust. We documented a variety of biochemical pathways and physical mechanisms that assist Trichodesmium to obtain Fe from mineral sources. We showed that dust packaging in the colony core is beneficial for uptake, since cell-particle proximity minimize Fe loss by diffusion, and that natural colonies enhance dissolution rates of dust-Fe and Fe-minerals. Lately we found that Trichodesmium and its associated bacteria act together to increase availability of dust-bound iron, where bacteria secrete Fe-binding molecules that promote dust dissolution and Trichodesmium provides dust and optimal physical settings for dissolution and uptake. In addition, we revealed that Trichodesmium can sense Fe and selectively choose Fe-rich dust particles, thus optimizing Fe supply.
Over the last years we expanded our research to the nutrient P and added new disciplines and techniques such as molecular biology (identify microbial interactions and biochemical response to dust), organic chemistry (siderophore characterization), high resolution imaging (Synchrotron, MALDI, NanoSIMS) and micro-electrodes (identify chemical gradients). Trichodesmium is predicted to flourish in the warmer, acidified and “dusty” future ocean. The mechanistic understanding gained by our research on its ability to utilize dust as a nutrient source will enhance our ability to predict the ocean’s operation modes in face of global change, and hence its impact on the atmosphere and climate.
Brief Summary of research:
The overarching aim of my research is to better understand the global material cycles in our planet, especially how the recycling of volatiles such as carbon and hydrogen from the surface to the deep Earth are related to the fluxes of oceanic and continental crust through time.
