People
Dr. Brian McSpadden Gardener
received his Ph.D. in Botany from Michigan State University in 1998. He began
work in the field of biological control of plant pathogens as an ARS
postdoctoral fellow under the guidance of Dr. David Weller. He joined the
faculty at the Ohio State University in 2001 where he currently serves as an
Assistant Professor. His research focuses on defining the diversity, population
dynamics, and ecological functioning of microbial populations that colonize crop
plants. Particular emphasis is given to studying Pseudomonas and
Bacillus spp. with potential for development as biopesticides.
Current Lab Members
Graduate Students
María-Soledad
Benitez is a graduate student in the Department of Plant Pathology at The Ohio
State University under Dr. McSpadden-Gardener's supervision. She is studying the
relationships between suppressiveness and phlD producing Pseudomonas
spp. in organic farming systems. She obtained her undergraduate degree of
Biological Sciences at the Universidad Católica in Quito, Ecuador. Her interests
are in microbial ecology, specifically in relation to changes in microbial
population structure as it relates to the functioning of agricultural and
natural ecosystems.
Rosa Raudales
is a graduate student in the Plant Pathology Department. She received her
B.S. in Agriculture Science and Production from Zamorano College in the year
2003. Prior to becoming a Master's degree student, she worked on applied
agriculture and farm production practices in Ginsheim, Germany and then at the
Integrated Pest Management Program at The Ohio State University. Her current
research interests focus on soil ecology and their effects on plant
production.
Technicians and Undergraduate Assistants
Seth
Maurer is a current undergraduate student at the College of Wooster majoring
in Biochemistry and Molecular Biology. He plans to attend Medical School upon
graduation. His current project is to test potential biofungicides generated
from bacterial strains.
Jefferson Amstutz is a 2008 graduate of Wooster High School and plans to attend Grove City College to study physics to pursue a career in Aerospace Engineering. His current project is the evaluation of the biocontrol potential of different bacterial strain formulations. He also helps with other tasks, including work on this website.
Sonia Masih is a senior at Wooster High School and is interested in pursuing a career in the science field. She is currently working on a project to test the efficacy of organic herbicides on the control of weed growth.
Recent Lab Graduates
Post-doctoral Fellows and Visiting Scientiests
Dr.
Kamal Krishna Pal
came as
Visiting Scholar under the Department of Biotechnology, Govt. of India, Long Term
Overseas Associateship programme in 2006. He hails from the National Research Centre for
Groundnut, Junagadh, Gujarat. Dr. Pal is looking for novel antifungal genes of
Bacillus subtilis involved in the biological control of plant pathogens.
Dr.
Dorith Rotenberg worked as a post-doctoral
researcher during 2006. Currently she is a research assistant professor at
Kansas State University. She received her Ph. D. from the Department
of Plant Pathology at the University of Wisconsin-Madison, and after spending
time as a post-doctoral research fellow in the Department of Soil Science at
UW-Madison, she discovered her love for studying the link between soil organic
matter (SOM) dynamics and microbial community structure and function related to
crop health. At OSU, she investigated the effect of farming practices on
the rhizosphere abundance of antibiotic-producing Pseudomonas populations
in corn and soybean fields as a means to elucidating soil factors that limit and
promote biological control functions in Ohio agricultural systems.
Graduate students
Raghavendra Joshi M.Sc. 2005. Currently is working as a PhD student in
molecular biology at the U. of Minnesota. He hails from the south Indian city
of Bangalore. Raghu obtained his Master’s in Biochemistry from UAS, Bangalore, India.
His broad interests are towards understanding molecular plant microbe
interactions. His research focused on the characterization of molecular markers unique to
Bacillus subtilis
with biocontrol capacities.
Laura Gutierrez Chapin M.Sc. 2004. Currently works as a research associate in the
Dept. of Horticulture and Crop Science at the Ohio State U. She hails from
upstate New York and completed a B.A. in Biology from Allegheny College in PA
Technicians and undergraduate assistants
Callie
Merry
is a student at Denison College where she is studying biology. During the summer
of 2007 she worked on conducting a variety of in vitro inhibition assays and PCR-based
characterization of 16S sequences from novel biocontrol strains.
Alejandra Sanchez hails from Columbia and is working part-time on various projects.
Kerry
Melanovsky attends the College of Wooster. She continued the work of
Dr. Pal, creating and evaluating mutants of biocontrol genes in Bacillus subtils.

Dario Chavez was a research assistnat. Currently he is pursuing a Ph.D. in Plant Breeding at U. of Florida. He was born in Riobamba, Ecuador and studied n Honduras at Panamerican School of Agriculture Zamorano until 2005, in which year thru January to April I was making my short term scholar at University of Georgia in the Distance Diagnostic through Digital Imaging project.
Clara Zumpetta
is currently pursuing a Master's degree in Plant
Pathology at OSU under Dr. Coplin. She hails from Northeastern Ohio and graduated in
2005 from Mount Union
College in Alliance, OH with a B.S. in
Biology and a minor in Chemistry. At the OARDC, her work centered on processing
corn and soybean samples in order to culture biocontrol strains of
Pseudomonas fluorescens and assaying the effects of a field’s slope on the
frequency and genotypic diversity of native phlD+ Ps. fluorescens
colonizing corn roots and rhizosphere. She is currentlypursuing a Master's
degree in the laboratory of Dr. Dave Coplin at The Ohio State University.
Amara Camp
is originally from Rhode Island and graduated from Juniata College in
Huntingdon, PA, with a Bachelor of Science in Biology and a minor in Spanish.
She assisted with greenhouse assays,
field sampling, data analysis, and general lab management, for the summers of
2004 and 2005. In 2006 she entered the graduate program in Plant Pathology at
Cornell University..
Ethan Horst
is a Wooster native and has been working at the OARDC every summer since his
sophomore year in high school. He attends Eastern Mennonite University in
Harrisonburg, Virginia where he is majoring in Biology and will be a junior this
fall. Ethan’s varied tasks include taking field samples, processing said
samples, computer and database work, and designing and maintaining this website.
Jacki
Mesaros is
originally from Southeastern Michigan. She attends the University of Toledo and
is majoring in Bioengineering. Her summer internship involves optimizing the
protocol used to isolate Bacillus, specifically B. subtilis and B.
pumilis. The main goal wasto compare the isolates of interest to other biocontrols through PCR Assays and DNA sequencing.
