He develops high-throughput, multidimensional spectroscopic and imaging methods to uncover how molecular- and nanoscale interactions govern macroscopic properties in complex systems. His work spans biological nanoparticles, quantum and energy materials, and solution-phase chemistry, with applications ranging from label-free viral diagnostics to light-directed materials synthesis. Dr. Harel has been recognized with the Packard Fellowship for Science and Engineering, the Presidential Early Career Award for Scientists and Engineers (PECASE), the 2023 […] - [Contact Us](https://deepspeclab.com/contact-us/): contact us Please contact Dr. Harel for any questions related to research, teaching, or outreach.

Graduate Students Our group is eager to […] - [Home](https://deepspeclab.com/): Illuminating the Secrets of the Microscopic World Harel Lab We study how the motion of matter shapes the behavior of complex systems, from the collective vibrations of viruses to the flow of energy that drives chemical reactions and crystal growth. Our goal is to understand how nanoscale dynamics influence the processes that define both living and nonliving systems. In biology, we use the natural vibrations of viruses and other biological particles to study their structure, interactions, and life cycle, and to develop new ways to detect them without labels. In materials science, we examine how energy moves and reorganizes during […] - [Research](https://deepspeclab.com/research/): Research Ongoing projects  Method Development Learn more BioSONICs Learn more Laser Synthesis Learn more Deep Learning Learn more Quantum Information Science Learn more Real-Time Ultrafast Spectroscopy Learn more Method Development Scientific progress depends not just on new ideas, but on new ways to observe the world at ever finer temporal, spatial, and energy scales. Many of the most important physical and chemical processes occur too fast, at scales too small, or in environments too complex for conventional techniques to capture. Developing new methods extends the limits of what we can probe, revealing materials and processes that were once invisible. Our […] [comment]: # (Generated by Hostinger Tools Plugin)
