  1. Ph.D, 1989 -- The Pennsylvania State University
  2. M.S., 1985 -- The Pennsylvania State University

Dr. Nese teaches a variety of courses, including Introduction to Weather Analysis (Meteo 201), Synoptic Meteorology Laboratory (Meteo 411), Introductory Meteorology (Meteo 003), Weather and Risk (Meteo 004), Data Analysis in the Earth Sciences (EBF 472), and Professional Development in the Atmospheric Sciences (Meteo 497A).

 He is also actively involved in the production of the Penn State Meteorology Department's weekday weather magazine show Weather World.  He provides regular features for the show on Wednesday evening in a segment called WxYz (WeatherWhys) - in 2015, he was awarded a Mid-Atlantic Emmy for WxYz with his college Marisa Ferger.  He also occasionally hosts the show and interviews Penn State faculty and prominent alumni.

Prior to joining the Penn State faculty, he was chief meteorologist at the historic Franklin Institute Science Museum in Philadelphia from 1998 to 2002. From 2002 to 2005, he was an on-air storm analyst at The Weather Channel.

Dr. Nese has co-authored two books: The Philadelphia Area Weather Book (with Philadelphia television meteorologist and Penn State alum Glenn Schwartz), which was awarded the 2005 Louis J. Battan Author’s Award from the American Meteorological Society; and a college-level introductory textbook A World of Weather: Fundamentals of Meteorology (with Penn State meteorologist Lee Grenci), now in its fifth edition.
