Marine and Environmental Systems
Welcome to Dr. L's research portal! My interests are varied and included data assimilation, electrical phenomena such as gigantic jets and terrestrial gamma ray flashes and wind/wave modeling. I have authored or co-authored 22 peer-review articles and have had 2 dozen proposals funded totalling approcimately $1.6 million. Over the past decade I have reviewed more than 30 articles and/or proposals and have served on both NASA and NSF panels. I have also graduated 8 Master's studets and I am currently supervising two Ph. D students who are both working under a NOAA Collaborative Science, Technology, and Applied Research (CSTAR) grant -- a study involving wind driven set-up in the Indian River Lagoon. I currently sit on three national committees -- including the University Center for Atmospheric Research Strategic Advisory Committee and Members Committee and the National Centers for Environmental Prediction Real-Time Mesoscale Analysis Committee. I spent 2013-2014 on sabbatical at the University of Utah in Salt Lake City Utah working on a data assimilation project (with surface winds) in conjunction with the National Mesonet Project.
I love to bike, hike, and kayak. I am the proud owner of two mutant beagles (rescues) and I am a quasi-vegetarian (I will eat some sustainable fish!). During the past 11 summers, I have been a volunteer for the Sea Turtle Preservation Society - giving presentations and guided tours on our local beaches during the summer months. I like to tweet about climate change, weather, and environmental issues in general. FOLLOW me on Twitter (@slazmo)!

Dr. Lazarus began his research career as an undergraduate assistant for Dr. James O'Brien at Florida State University, from 1984-1985. During that span, he spent the summer of 1984 as an under-graduate fellow working with Dr. Theodore Fujita at the University of Chicago. Before attending graduate school, Dr. Lazarus was employed at the Stennis Space Center in Bay St. Louis, Mississippi, where he worked on a statistical ocean modeling project.
Dr. Lazarus completed his master's and Ph D. work at the University of Oklahoma. His work in the areas of modeling severe convection and data assimilation was augmented by tornado chasing during his graduate student years in Oklahoma. As a post-doc at the Univesity of Utah, he was involved in several projects including real-time weather analysis work in support of the Winter Olympic games, GCM (cloud) evaluation with the Atmospheric Radiation Measurement Program (ARM), and served as the local AMS chapter president--representing groups from the University of Utah, the National Weather Service and Western Region Headquarters. More recently (2004) Dr. Lazarus was a visiting scientist at the National Centers for Environmental Prediction in Washington, D.C. and serves on a national committee that is overseeing an operational mesoscale analysis project referred to as the Real-Time Mesoscale Analysis (RTMA).
Dr. Lazarus is a member of the American Meteorological Society and the American Geophysical Union. He is an active participant in the peer-review process having reviewed more than 20 proposals and/or journal articles. Dr. Lazarus has authored or co-authored about two-dozen articles in peer-review journals. He spent a recent sabbatical at the University of Utah for the academic year (2013-2014).
