David is a senior research associate at Cornell AgriTech in Geneva, and provides expertise in host ontogenic resistance, pathogen biology, ecology, and epidemiology, as well as microscopy and digital imaging.


Mark Rea's headshotMark Rea, Professor and Director, Lighting Research Center
Rensselaer Polytechnic Institute, Troy, NY 12180

The Lighting Research Center at Rensselaer Polytechnic Institute is developing an imaging system to automatically phenotype powdery mildew on grape leaf samples. Current methods use human visual assessment and are time consuming. Mark’s goal is to develop an imaging system with artificial intelligence that can automatically analyze 1600 samples per day.


Daniel Lacasa's headshotDaniel Lacasa, Postdoctoral Associate, Cornell University
