Role: Infrastructure Overlord


Paul Zimdars is a Senior System Administrator for the RCMES project. He has worked over 10 years on multiple JPL flight and non-flight related projects. He has extensive knowledge in Linux and Unix administration including advanced Network / Storage / and Web application troubleshooting and support.

Paul Loikith

Role: RCMES Science Postdoc


Dr. Paul Loikith is a California Institute of Technology Postdoctoral Scholar at JPL. Paul's research interests focus on weather and climate dynamics with emphasis on atmospheric mechanisms associated with extreme temperatures and the evaluation of these phenomena in climate model simulations. As an RCMES team member his work has focused on developing methodologies for evaluating temperature distributions, extremes, and associated mechanisms in NARCCAP regional climate models using high-resolution reanalysis. Paul has a Ph.D. in atmospheric science from Rutgers University.

Kyo Lee

Role: RCMES Science Postdoc


Kyo is a California Institute of Technology Postdoctoral Scholar at JPL. While studying both atmospheric sciences and statistics, Kyo became very interested in statistical downscaling which he think as one of the most practical applications of atmospheric sciences for policy makers and insurance companies. Through the adaptation and extension of previously developed statistical tools, he develops metrics included in RCMES by introducing a practical approach for quantitatively evaluating the performance of regional climate models. Dr. Lee has a Ph. D. in Atmospheric Sciences from University of Illinois at Urbana Champaign.

Kim Whitehall

Role: RCMES Researcher, Ph.D Student, Howard University


Kim Whitehall is a PhD student in the Howard University Program in Atmospheric Sciences (HUPAS), Washington, D.C. and is working with Dr. Gregory S. Jenkins. Her main research interests reside in tropical climate dynamics, and the weather and climate modeling of that region. Prior to pursuing her PhD, she worked 4 years as a climatologist in the Caribbean. During that time, she developed technical skills with regards to using, manipulating, and evaluating climate and weather model datasets, but also developed an understanding of the impacts and concerns with regards to climate dynamics on societies and economies in the tropics.
