Our Collaborators

Our research is only possible due to our amazing collaborations. Here’s an overview of who we work with (listed alphabetically):

Mike Betancourt is an applied statistician and a brilliant modeler. He has worked a lot on the Hamiltonian Monte-Carlo algorithm for Stan–a platform for statistical modeling and high-performance statistical computation. Watch his speech on Scalable Bayesian Inference with Hamiltonian Monte-Carlo.

Pat Bowen is a research scientist in viticulture and plant physiology working at AgCanada in Summerland. She is an expert on sustainable vineyard development, the Okanagan winegrowing region. She works closely with Carl Bogdanoff, learn more about their work in the 2019 CCOVI Lecture Series.

Carl Bogdanoff is a biologist specializing in viticulture and plant physiology working at AgCanada in Summerland. His primary areas of expertise include cold hardiness and the Okanagan winegrowing region.


Ben Cook is a climatologist at NASA GISS who specializes in phenology, climate change, and drought.

Iñaki García de Cortázar-Atauri is an expert in winegrape phenology. He is a crop modeler at INRAE-Avignon.

Thierry Lacombe is a lead ampelographer and winegrape diversity expert at INRAE, Montpellier, UMR AGAP. This research unit helps to run Domaine de Vassal–the largest ampelographic collection in the world.


Ignacio Morales-Castilla is a macroecologist and biogeographer who worked as a Research Associate with us in 2016-2017. Today, he’s particularly interested in Iberian winegrape varieties.

Amber Parker is an expert on winegrape phenology at Lincoln University. She has been instrumental in helping us gather climate and phenological data, as well as build models.

Kees van Leeuwen has studied the impact of climate change on grapes for a long time and was foundational to our work when he agreed to meet Dr. Wolkovich in 2011 in Bordeaux. Learn more about the VitAdapt project, where he is growing a diversity of varieties and studying which varieties will fare best in warmer Bordeaux climates.

Andy Walker is a ampelographer working at UC Davis who has been an amazing resource for our work. Learn about his work breeding new varieties for Pierce’s disease and read his 2015 Conversation article discussing how climate change may bringing a ‘golden age of grape breeding’.
