Team Leader

Lee Kalcsits, Assistant Professor: Tree Fruit Physiology
Phone: 509-293-8764, E-mail:

Lee is the lab leader and joined WSU in 2014 to conduct research on tree fruit physiology. Growing up in Saskatchewan, Canada, a challenging environment to grow tree fruit. However, despite these challenged, he was raised on a small fruit orchard that produced strawberries, raspberries, saskatoons (serviceberries, juneberries), sour cherries and cold hardy apples where he developed a passion for horticulture and more specifically, trees. After earning a B.S.A. in Horticulture from the University of Saskatchewan, he was introduced to research on poplar trees, a common model tree species used in tree physiology. He earned his M.Sc. in Plant Sciences from the University of Saskatchewan and Ph.D. in Forestry from the University of British Columbia as a NSERC Vanier Scholar working with poplar with an emphasis on dormancy and nitrogen fluxes, respectively. He then joined the University of Victoria as a NSERC CREATE Postdoctoral Fellow until accepting a position with WSU and back to his roots, tree fruit horticulture and physiology.

Postdoctoral Research Associate

Victor Blanco, Ph.D.

Victor joined Lee Kalcsits’ tree fruit physiology lab in October 2020 as a postdoc. He is an Agricultural Engineering and M.S. in Advanced Techniques for Agricultural Alimentary Research and Development. Victor obtained his Ph.D. in Agronomy, at the Technical University of Cartagena, Spain and he was a visiting student researcher at the University of Amsterdam and the Pontifical Catholic University of Chile. He has focused his work on the physiological and agronomical response of fruit trees to water stress and environmental conditions. During his stay he wants to broaden his knowledge of water and nutrient uptake and distribution in fruit trees and the physiological mechanisms contributing to the development of physiological disorders in tree fruit.


Erica Casagrande Biasuz, Ph.D. Student
Phone: 509-339-9880, E-mail:

Erica is from Caxias do Sul, Brazil. She graduated with a B.S. in Agricultural Science from the University of Modena and Reggio Emilia (UNIMORE) in Italy. In 2016 she completed her Master’s in International Horticulture Science at the University of Bologna, Italy. During her Master’s program she also studied Plant Pathology and Biotechnology at Technical University of Munich, Germany. Her Master’s thesis was focused on “Assessment of bioassay for the prediction of apple replant disease severity”. In August 2017, she started her Ph.D. with Dr. Kalcsits. Her research focuses on understanding the link between water and nutrient uptake and distribution in apple trees.

Alexander Haase, M.S. Student

Alex is from Lynnwood, Washington. He graduated with a B.S. in Integrated Plant Sciences from Washington State University in May of 2019. He was an undergraduate intern at the WSU Mount Vernon research and extension center, where he worked on assessing the effectiveness of utilizing dry matter content as a quality metric for cider apples. In August 2019, Alex began working on his M.S. in Horticulture at Dr. Kalcsits’s lab. His research will focus on identifying genotypic variation in sunburn susceptibility of apple fruit and the developmental and physiological changes that contribute to sunburn resistance.

Noah Willsea, M.S. Student



Orlando Howe, Technical Assistant
Orlando joined the lab in November 2018.  He is a student at Wenatchee Valley College.

Schaefer Buchanan, Technical Assistant
Schaefer joined the lab in September 2019.  He has a B.A.Sc. in Geological Engineering from the Colorado School of Mines.
