Dr. Karl Ravet

Research Scientist III

Karl Ravet is a molecular biologist who joined the Crop Genomics lab in January 2018. Karl completed his PhD in the “Integrative Biology Institute for Plants-CNRS-INRA” in Montpellier (France) in 2008. Karl joined Colorado State University as a post-doc in 2009 and then has received a Marie Curie fellowship to develop research programs on plant nutrition and photosynthesis (2011-14). Since Karl has become a Research Scientist III and is currently applying genomics and CRISPR-Cas technology to major crops such as bread wheat (Triticum aestivum) and potato (Solanum tuberosum). Karl is also leading our research program on industrial hemp (Cannabis sativa).

Curriculum vitae

Rocío Alarcón-Reverte

Research Associate

Rocío Alarcón-Reverte joined the Pearce Lab in November 2018 as Research Associate IV. Rocío studied Agricultural Engineering (Plant production field) at the Universidad Politécnica de Valencia (Spain) and completed her PhD in weed science at Rothamsted Research (UK). Rocío is working in the development of TILLING lines to characterize target genes involved in quality, production and disease resistance traits.

Andrew Katz

PhD Student

Andrew joined the Pearce Lab August of 2017. He is characterizing a QTL on chromosome 6BL that affects spikelet number per spike in hard winter wheat as part of the Wheat Coordinated Agricultural Program ( He is also working to develop CRISPR/Cas9 genome editing capabilities in Colorado Wheat Varieties. Andrew received his Bachelor of Science in Agronomy from Purdue University in May of 2014 where he investigated the molecular arms race between the Hessian Fly and Winter Wheat. He then moved on to the Joint Genome Institute where he built molecular tools for Brachypodiumspecies. While there, Andrew focused on mycological and microbial plant interactions. Andrew hopes to one day lead a plant breeding program that utilizes a diverse tool box of molecular and agronomic tools.

Curriculum Vitae

Yucong Xie

PhD Student

Yucong is a Ph.D. student in the Stephen Pearce lab since 2018 fall. She is now interested in utilizing functional genomic, molecular genetics, transcriptomic, and bioinformatic tools to identify new candidate genes for Wheat Streak Mosaic virus (WSMV) resistant traits in Colorado winter wheat varieties. Yucong completed her BSc from Huazhong Agricultural University in China (2015) and MSc from University of Florida (2017) with a focus on Horticultural Sciences.

Carl VanGessel

PhD Student

Carl joined the Pearce lab in Spring 2019 as a Ph.D. student interested in genomic analysis of wheat. His work focuses on characterization of phenological response to ambient temperature using functional genomic, transcriptomic, and bioinformatics tools. Carl is also working on developing viral immunity in monocots using CRISPR/Cas machinery. He is also a member of Dr. Scott Haley’s Wheat Breeding program at CSU. Carl received his B.S. in Biology from Catholic University and M.S. in Plant Pathology from North Carolina State University where he focused on mapping resistance to Ug99-stem rust in wheat.

Patricia Vail

Undergraduate Student

Patricia’s research is focused on using gene editing tools to develop constructs that will improve drought tolerance and wheat quality. She is a Soil and Crop Sciences major with a focus in plant genetics.

Forrest Wold-McGimsey

Undergraduate Student

Forrest joined the Pearce lab in January of 2020 and assists in both laboratory and field projects. He is currently working towards a B.S in Soil and Crop Sciences with a concentration in plant biotechnology, genetics and breeding.
