Joseph Katz

About

Joseph Katz is the William F. Ward Sr. Distinguished Professor at Johns Hopkins Whiting School of Engineering and a member of the National Academy of Engineering. He is known for his outstanding contributions to engineering research, practice, and education, particularly in the development of optical methods in experimental fluid mechanics for turbomachinery, cavitation, turbulence, and environmental flows. His research focuses on experimental fluid mechanics and the development of advanced diagnostics techniques for laboratory and field applications. He directs the Laboratory for Experimental Fluid Dynamics, which has studied laboratory and oceanic turbulent boundary layers, flows, and instabilities in turbomachines, flow-structure interactions, the swimming behavior of marine plankton in both laboratory and ocean environments, as well as cavitation, bubble, and droplet dynamics in various systems. Katz has co-authored more than 150 journal papers, 220 conference papers, several book chapters, and holds seven patents. His research has been funded by multiple agencies including the Office of Naval Research, NSF, NASA, Gulf of Mexico Research Initiative, Airforce Office of Scientific Research, Department of Energy, NOAA, and Fisheries and Oceans Canada. He is a co-founder and current director of the Johns Hopkins Center for Environmental and Applied Fluid Mechanics. Katz is a fellow of the American Society of Mechanical Engineers (ASME) and the American Physical Society…

• Reconstructing velocity and pressure from sparse noisy particle tracks using Physics-Informed Neural Networks

  arXiv (Cornell University) · 2022 · 6 citations

  Senior authorCorresponding

  Volume-resolving imaging techniques are rapidly advancing progress in experimental fluid mechanics. However, reconstructing the full and structured Eulerian velocity and pressure fields from sparse and noisy particle tracks obtained experimentally remains a significant challenge. We introduce a new method for this reconstruction, based on Physics-Informed Neural Networks (PINNs). The method uses a Neural Network regularized by the Navier-Stokes equations to interpolate the velocity data and simu…

  1st authorCorresponding

  OBJECTIVES: Xerostomia, or dry mouth, is a condition that results from the reduction or absence of saliva flow secondary to the use of certain medications. The objective of the present study was to analyze the relationship between xerostomia patients and the consumption of serotonin norepinephrine reuptake inhibitors (SNRIs). METHOD AND MATERIALS: The University of Florida (UF) Integrated Data (IDR) i2b2, for the period of June 2015 to September 2022, was used based on aggregates of the Internat…

• Ion and Electron Acoustic Bursts during Anti-Parallel Magnetic Reconnection Driven by Lasers

  arXiv (Cornell University) · 2022-09-26 · 1 citations

  preprintOpen access

  Magnetic reconnection converts magnetic energy into thermal and kinetic energy in plasma. Among numerous candidate mechanisms, ion acoustic instabilities driven by the relative drift between ions and electrons, or equivalently electric current, have been suggested to play a critical role in dissipating magnetic energy in collisionless plasmas. However, their existence and effectiveness during reconnection have not been well understood due to ion Landau damping and difficulties in resolving the D…

• The use of chlorhexidine mouthwash and diagnosis of primary hypertension in a large hospital cohort.

  PubMed · 2025-02-26

  article1st authorCorresponding

  OBJECTIVES: Small-scale studies reported increased blood pressure in patients using chlorhexidine mouthwash with the rationale that the rinse mitigates nitric oxide production by oral bacteria. The present study evaluated whether prior use of chlorhexidine mouthwash can be associated with an increased odds ratio (OR) for primary hypertension in a large hospital cohort. METHOD AND MATERIALS: The i2b2 NIH-established platform was used to search for deidentified medical information coded by ICD-10…
