John is from southeast Pennsylvania and graduated with degrees in horticulture from Delaware Valley College and Michigan State University. John helped develop the concepts of DIF, DROP and DIP used to control stem elongation today while in graduate school. Following college, he served as a Professor at the University of Minnesota where he identified how daylength, light intensity, and temperature affect the flowering of bedding plants, cacti and succulents, identified lighting protocols for leafy green crops, identified unique PGR combinations to control growth, and studied high-temperature effects on flowering and root development. John recently became the Chair of the Department of Plant Science and Landscape Architecture at the University of Maryland where he continues his research. Aside from academics, he has been a production consultant for 4 of the top 10 growers in the US for 30 years.
