Lazarus, Steven

Associate Professor
Marine and Environmental Systems

Welcome to Dr. L's research portal!  My interests are varied ranging from data assimilation to wind/wave modeling.  I have authored or co-authored 21 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. In this period I have also graduated 8 Master's studets. I currently sit on three national committees and have ties to the National Centers for Environmental Prediction on national mesonet related work. This academic year (2013-2014) I am on sabbatical at the University of Utah in Salt Lake City Utah.

 

Personal Overview

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 10 summers, I have been a volunteer for the Sea Turtle Preservation Society - giving presentations and guided tours on our local beaches.

Professional Experience

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 Florida Academy of Sciences, 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 is currently on sabbatical at the University of Utah for the academic year (2013-2014).
