Jules S. Jaffe
Principal Investigator
Dr. Jaffe received a B.A. Cum Laude from SUNY at Buffalo (Physics) in 1973, a M.S. from Georgia Institute of Technology, Atlanta (Biomedical Information Science) in 1974, and a Ph.D. from University of California, Berkeley (Biophysics) 1982. His interests include Image and signal processing science, development of 3-dimensional in-situ sensors for oceanography (optical and sonar). Underwater optical and sonar imaging. Biomedical imaging. Autonomous vehicle development.
Devin Ratelle
Research and Development Engineer

Devin got his start in the Jaffe lab as part of an undergraduate engineering design project. He joined the lab as an engineer after receiving a BS in Mechanical Engineering from UCSD in 2013 and has continued on ever since. His work with the lab includes underwater autonomous vehicles, control algorithm tuning, electrical and mechanical design for underwater imaging systems, and fabrication and assembly.

Pichaya Lertvilai
Graduate Student

Pichaya has been a student in the Jaffe Lab since 2016. His research focuses on developing imaging platforms for ecological studies. He is currently working on an in situ imaging system for marine microogainsms and a low-cost imaging platform for zooplankton. Originally from Thailand, Pichaya received his B.S. in General Engineering with an Emphasis in Environmental Analysis from Harvey Mudd College, CA. He is currently working towards his PhD in Oceanography, which he is expected to complete in 2021.

Kevin Le
Master's Student

Kevin has been apart of the Jaffe Lab since 2017 when he first began doing work on an undergraduate machine learning project. He joined the lab as an Application Programmer for a year after receiving a BS in Electrical Engineering and Computer Engineering (ECE) from UC San Diego and then worked in the industry developing machine learning models. He has now returned to the lab to do deep learning/computer vision research for our underwater cameras, as part of his M.Sc in ECE, again at UC San Diego. Kevin hopes to finish his M.Sc. work in 2020.

Joe Walker
Joe joined the Jaffe Lab in 2018 after receiving a BS in Environmental Science/ Math minor from the University of Portland. His research focuses on using novel imaging technology together with deep learning/computer vision to better understand microecosystems.  He is currently working towards his PhD in Applied Ocean Science and is planning to graduate 2023.
Or Ben-Zvi
Postdoctoral Scholar
Or joined the Jaffe lab in 2022 moving to San Diego from Eilat, Israel. After exploring the phenomenon of coral fluorescence and corals’ ecophysiology during her previous studies, Or is now working on an underwater chlorophyll a fluorescence imaging system. The Benthic Underwater Microscope PAM (known as the BUMP) will allow her to explore photosynthesis at fine scales such as the relationship between corals and their symbiotic algae. Or has a BSc in Biology, and MSc and PhD in Zoology from Tel-Aviv University, Israel.
