Istvan Laszlo received an M.S. degree in Astronomy/Physics and a Ph.D. degree in Physics from the Eötvös Loránd University in Budapest, Hungary. He worked at the Institute for Atmospheric Physics of the Hungarian Meteorological Service before joining the faculty of the Department of Atmospheric and Oceanic Science at the University of Maryland at College Park, Maryland. Since April 2001 he has been with the National Oceanic and Atmospheric Administration (NOAA).

Istvan Laszlo's research interests include atmospheric radiation, radiative transfer, radiation budget and remote sensing of atmospheric and surface properties from space. He is a co-author of the well-known Discrete Ordinate Radiative Transfer (DISORT) code, worked on estimating the broadband top of atmosphere albedo from narrowband sensors; developed algorithms for determining the shortwave radiation budget, surface albedo, and aerosol optical depth from satellite data. He is currently working on remote sensing of aerosol properties from space and on the estimation of the shortwave radiation budget from operational geostationary satellites.

Istvan Laszlo was an elected member of the International Radiation Commission of the International Association of Meteorology and Atmospheric Physics (IAMAP). He was a member of the Scanner for Radiation Budget (ScaRaB) International Science Team, the NPOESS Science Teams, and the Operational Algorithm Teams for the NPOESS Aerosol Polarimeter Sensor (APS) and for the NPOESS Earth Radiation Budget (ERBS) instrument. He also has a strong interest in and connection to the NASA Clouds and the Earth's Radiant Energy System (CERES) project. He is the co-chair of the Earth Radiation Budget Oversight Panel (EPOP), chair of the GOES-R Radiation Budget Algorithm Working Group at NESDIS, algorithm co-lead of the NPP Aerosol Calibration/Validation Team, and a member of the NPP Science Team.

Istvan Laszlo is the aerosol and radiation budget lead scientist at NESDIS/STAR. He served as the Acting Chief of the Environmental Monitoring Branch between September 2007 and August 2008.
