Dr. Victor Gensini - Associate Professor Department of Geographic and Atmospheric Sciences Northern Illinois University

Dr. Gensini's research umbrella covers extreme weather and climate, with specific interests focused on: severe convective storms, synoptic/mesoscale meteorology, applied climatology, GIS techniques, geoscience data visualization, weather forecasting, and climate change. His past research has primarily focused on the relationship between severe convective storms and climate change by utilizing dynamical downscaling from a convective permitting regional climate model. Currently, a majority of Dr. Gensini's research is examining weather and climate dynamics that explain variability in extreme weather (e.g., hail, tornadoes, heavy rain, heat waves) frequency and analyzing ways to forecast these events at sub-seasonal to seasonal time scales. Dr. Gensini holds the CCM designation from the American Meteorological Society, serves an Associate Editor for WAF and an Editor for JAMC, and is a member of several NOAA NGGPS committees. In addition, he also has a guest faculty research appointment at Argonne National Laboratory and serves as Deputy Director for the NIU Center for Research Computing and Data.

Dr. Robin Tanamachi - Assistant Professor of Earth, Atmospheric, and Planetary Sciences (EAPS) Purdue University

Dr. Robin Tanamachi leads the Weather Radar Research Lab at Purdue University. She is a research meteorologist specializing in radar-based studies of severe convective storms and tornadoes. Prior to joining the faculty at Purdue in 2015, she spent 13 years working in the severe weather capitol of the Great Plains: Norman, Oklahoma. She participated in numerous field programs, including VORTEX2, studying tornado structure and behavior with mobile radars. Prof. Tanamachi spearheaded an effort to install a gap-filling weather radar at Purdue, called the X-band Teaching and Research Radar (XTRRA). She has authored or co-authored 17 refereed publications, presented at conferences all over the world, and even been featured in a children's book (The Tornado Scientist by Mary Kay Carson and Tom Uhlman). Recently, she's branched out into the field of Atmospheric Science Education Research, studying the beneficial impact of field experiences on meteorology students.

David Beachler - Science Operations Officer NWS Indianapolis, IN

David is the Science Operations Officer (SOO) for the National Weather Service Indianapolis Office. Prior to arriving in Indianapolis, David was the SOO at the Marquette MI NWS-WFO. David has served many roles throughout his career within the NWS, stretching from the Atlantic Ocean, Great Lakes, Middle Atlantic, and Washington DC. The experiences having worked tropical events, to powerhouse Great Lakes snow/wind events, Nor’easters on the East Coast, and EF4 Fairdale IL tornado has allowed for some incredible experiences and opportunities to share through training to the staff at the NWS Indianapolis WFO.


As the SOO, David is responsible for overseeing the training and development of forecasters on staff at the NWS Indianapolis. In addition to internal training and ensuring forecasters have the latest tools available to aid in the warning decision making process, David also works from time to time with academia to look into new approaches and methods that may someday become the standard approach to forecasts of small and large weather events.
