Retired Team


Bill Dvorak, founding director of Camcore, retired in 2014 after 34 years in that position. Bill began his career in forestry with a B.S. in forestry at Michigan State University. Upon completing his undergraduate degree, Bill spent two years working in the Fiji Islands with the US Peace Corps. It was in Fiji that Bill first developed his love for forest genetics and tree improvement, and his passion to put the right species, provenances and genotypes into forest plantations across the globe. Bill continued his education at NC State University, beginning an M.S. program. He took the position of Director of Camcore in 1980, and while working as Director he continued his graduate studies, completing his Ph.D. in 1990.  Bill continues to assist Camcore as an Emeritus Professor.


lopezJuan Luis Lopez was the Associate Director of Camcore and retired in 2022.  Juan has a B.S. in Forest Engineering from Universidad Nacional de Colombia,  an M.F. in Forest Management from the University of Georgia, a M.S. from University of Toronto, and a Ph.D. in Forestry from NC State University.  Prior to joining Camcore, Juan worked with Smurfit Kappa Colombia in a number of positions, including Nursery Manager, Operations Manager, and Wood Procurement Manager, and for Olympic Resource Management in Vancouver, Canada.  His research interests are pine hybrids, wood quality, and economic value of tree breeding programs.


Current Students

Lauren Gonzalez is a Ph.D. student at North Carolina State University under the supervision of Robert Jetton. Originally from Miami, Florida, Lauren got her bachelor’s of science in biology from the University of North Carolina at Charlotte and her master’s of science in biology from Western Carolina University. Her research focuses on the management of Adelges tsugae, hemlock woolly adelgid, as well as conservation of eastern and Carolina hemlock. Through the use of silvicultural techniques, she will study the effects of canopy condition, competition control, and their integration with chemical and biological pest management on the establishment and early growth of hemlock seedlings planted for restoration.

Gustavo MArtins

Gustavo Martins is a PhD student in Forest Genetics.  Originally from Minas Gerais – Brazil, Gustavo got his undergraduate degree in Forest Engineering and his Master’s degree in Genetic and Plant Breeding from Lavras Federal University – UFLA. He is an employee of RGE/APRIL Asia in Indonesia, where he is  the Eucalyptus Breeding Program Leader. His research focuses on understanding the quantitative genetic base of variation of traits of  Acacia crassicarpa, including reproductive and phenology, tree growth and stem form, wood properties/quality, and biotic resistance traits. The research also considers the evaluation of the potential of genomic technologies to accelerate breeding, increase selection intensity, and improve accuracy of genetic values prediction.

Dominic ManzDominic Manz is an PhD student working as part of Camcore’s domestic conservation program under the direction of Robert Jetton. For his research he is assessing the susceptibility of eastern and Carolina hemlocks to the root rot pathogen Phytophthora cinnamomi. He is currently writing up his study results and plans to continue with Camcore as a PhD student beginning in summer 2020 when he will begin a project related to scale insect management in Fraser fir Christmas tree plantations. Prior to joining Camcore, Dominic completed his BS degree in Forestry at NCSU.


Leonida Cherotich is a Ph.D student at North Carolina State University, currently studying Forestry under the Supervision of Prof. Gary Hodge. She is from Kenya, where she works at the Kenya Forestry Research Institute (KEFRI) at the Tree Improvement Programme. Leonida got her Bachelor’s degree at Kenyatta University in Biotechnology and a Master’s of science degree from Jomo Kenyatta University of Agriculture and Technology in Biotechnology and Plant Breeding. She is currently working on a project that aims at the improvement of vegetative multiplication rate of pine seed; and sterile propagation of mature pine genotypes, with the support from Camcore. She is specifically interested in application of techniques such as somatic embryogenesis and organogenesis to come up with refined protocols on how to improve vegetative propagation of different species of pine.


Juan Pedro Posse is working on a PhD in forest genetics, studying the genetic EucUru09_spacingTrial11control of wood and growth traits in a large population of E. dunnii.  Juan Pedro works in Uruguay




Mindoro Razoki is a M.S. student at NCSU under the supervision of Camcore. Originally from Indonesia, Mindoro earned his undergraduate degree in Forest Product Technology from Gadjah Mada University (UGM). Having ten years’ experience in wood technology, he is currently working in Sinarmas Forestry, Indonesia, as the Wood Technology Department Leader. His research focuses on quantifying the variations of wood properties of Eucalyptus pellita among different ages and estimating the age-age correlation. The study is designed to provide ample information to examine the option of early selection in breeding programs and the economic implications of different harvesting ages.

Jacob Bost is a M.S. forestry student working on biomass estimation of the pocosin swamps in the Hoffman forest in eastern North Carolina. He started his forestry education by getting his associates degree from Montgomery Community College then transferring to NCSU to complete his BS in forestry.
He plans to graduate with his M.S in the spring of 2024.



  Gina Zabala Martinez is a M.S. student at NCSU  working with Camcore as research assistant under the direction of Robert Jetton.  Gina is from Colombia and holds a B.S in Forest Engineering from Universidad del Cauca (Colombia). In Colombia Gina has worked withSmurfit Kappa Colombia for two years, first in the silviculture team and then as a researcher. Her research focuses on  forest pathology. Through the use of lab and inoculation techniques, she is testing the susceptibility of different families of Eucalyptus to a bacterial pathogen (Ralstonia Solanacearum) to have data in order to propose management strategies for this pathosystem.
