Rapid Rewarming of Cryo-preserved Specimens
This project explores methods for rapid, uniform rewarming of cryogenically-frozen cells, tissues, and organisms using lasers and nanoparticles.
Mitigation of Surface Erosion by Cavitation
This project explores methods to mitigate surface erosion due to cavitation using multiscale surface modification techniques such as laser-induced periodic surface structures (LIPSS) within hierarchical laser-written structures. *This project is led by Ph.D. candidate Juan Carlos Gonzalez Parra at the University of California, Riverside.
Transparent Cranial Implants for Laser Brain Therapy
This project investigates the optical and thermal properties of transparent ceramic materials such as Aluminum Oxynitride (ALON) and nanocrystalline yttria-stabilized zirconia (nc-YSZ) for use as cranial implant materials for laser therapy applications.
Non-invasive Blood Perfusion Monitoring
This project utilizes laser speckle imaging with various enhancements to develop clinical imaging devices to monitor blood perfusion. *This project is led by postdoc Aditya Pandya at the University of California, Riverside.
Cavitation Bubble Dynamics Near Gas-entrapping Microstructures
This project explores the use of entrapped air on microtextured surfaces to control the mechanics of nearby cavitation bubbles and the direction of jets caused after bubble collapse. *This project is led by Ph.D. candidate Vicente Robles at the University of California, Riverside.
Non-linear Absorption and Thermal Stability of Titanium Nitride (TiN) and Gold Nanoparticles
This project explores the thermal responses and stability of nanoparticles irradiated in the nanosecond near-infrared regime, for use in laser rewarming of cryopreserved specimens. *This project is led by Ph.D. candidate Ariana Sabzeghabae and postdoc Carla Jose Berrospe-Rodriguez at the University of California, Riverside.
Vernier Effect and Multimodal Interference in Optical Fibers
This project studies the Vernier Effect, a modulation in transmitted wavelength within multi-core optical fibers. In addition, we study multimodal interference in few-mode fibers and multimodal fibers. These phenomena may generate ring-shaped intensity profiles as well as azimuthal complex intensity profiles such as optical vortex.
