Dr. Overall has given hundreds of national and international presentations and short courses and is the author of over 100 scholarly publications on behavioral medicine and lizard behavioral ecology and dozens of textbook chapters.  Her first textbook, Clinical Behavioral Medicine for Small Animals, was published in 1997.  Her new book, Manual of Small Animal Clinical Behavioral Medicine, will be published by Elsevier in 2009, accompanied by an instructional video, Humane behavioral care for dogs:  techniques for the treatment and prevention of canine behavior problems..  Another text, Behavioral Medicine for Old Dogs, will follow later, as will a revision of her first text.  She is also a columnist for DVM Newsmagazine.  Dr. Overall is the editor-in-chief for the Elsevier journal, Journal of Veterinary Behavior: Clinical Applications and Research.


Dr. Overall ran the behavior clinic at Penn Vet for more than a dozen years and is now on the  faculty of the Center for Neurobiology and Behavior in the Psychiatry Department at Penn Med as a Research Associate.  Dr. Overall’s research focuses on neurobehavioral genetics of dogs and the development of normal and abnormal behaviors, and on the development of behaviors beneficial to working dogs and their genetics.


Dr. Overall frequently consults with service and assistance dog organizations and military and police organizations that use dogs in any capacity.  She also consults frequently with law makers regarding legislation affecting dogs, and is frequently called as an expert in abuse, neglect, and aggression cases involving dogs.  Additionally, Dr. Overall is often consulted by humane shelters about evaluation of dogs and improving canine care.  She speaks regularly at the Pennsylvania Bar Association Institute on canine issues.  Dr. Overall is past Co-Chair of the US government supported SWGDOG (the Scientific Working Group on Dogs and Orthogonal detector Guidelines), and serves on the board of Directors of both charitable (PALS for Life) and working dog (International Working Dog and Breeding Association [IWDBA]) organizations.  In 2008 Dr. Overall was appointed by PA Governor Rendell to the Commonwealth of Pennsylvania Canine Health Board.  She was awarded the 1993 Randy Award for Excellence and Creativity in Research.  In 2005, Dr. Overall was voted the Small Animal Speaker of the year at the North American Veterinary Conference. 


When she is not traveling, speaking, writing, seeing patients, or conducting research, she tries to play with her 4 Australian shepherds and husband - and collaborator - Dr. Art Dunham, who shares her passion for the wonder and logic of science, fine art, language, culture, wild places, and doing the right thing.

Dr. Art Dunham

Dr. Art Dunham received his PhD at the university of Michigan in Ecology and Evolutionary Biology.  His research interests have focused on all things mathenmatical pertaining to animals and the populations in which they live. As an ecologist and applied inferential statistician he has worked  on the effects of conspecifics and microclimates on lizards, global warming and implications for West Nile virus, dinosaur physiology and allometry, and performance assessment and its genetic associations in working dogs.  He is increasingly being asked by working dog programs to help them improve their test reliability.

Dr. Dunham is currently professor of Biology and Associate Chair of the Biology Department of the University of Pennsylvania, in Philadelphia, PA, USA.


Dr. Soraya Juarbe-Diaz

Dr. Juarbe-Díaz has the longest established behavior referral practice in the state of Florida. Known as Dr. JD to owners throughout the state, she received a B.S. in biology in 1983 and her D.V.M. degree in 1987 both from Cornell University. She was in mixed practice for about 1 1/2 years and in small animal practice for 5 1/2 before returning to her alma mater for specialty training in veterinary behavior medicine. She finished her residency in 1996 and received her board certification in 1997. Certification by the Animal Behavior Society as a Certified Applied Animal Behaviorist was conferred in 1999.

In the fall of that year she relocated to the Sunshine State where she began the longest-established a referral veterinary behavior practice, seeing cases throughout several Florida locations. She has been an adjunct professor at the University of Florida's College of Veterinary Medicine and an Assistant Professor at the University of Tennessee's College of Veterinary Medicine, running the behavior clinic at each university and teaching veterinary behavior medicine to students and all interested hospital staff while also seeing patients for treatment of behavior problems.  She was a monthly guest host for a nationally syndicated live radio show for 6 years where she answered radio listeners' questions on the air.

Dr. Juarbe-Díaz has served in several committees of the American College of Veterinary Behaviorists and as the Assistant Editorial of the Journal of Veterinary Behavior: Clinical Applications and Research and continues to be a reviewer for several veterinary professional journals. She is a speaker at local, national and international veterinary meetings and behavior conferences and also the author of a variety of papers and articles on behavior written for professional and lay publications. Her professional interests include behavioral disorders in domestic species and animal cognition in particular.

Because of her experience both in academia and in general practice, she brings to her professional endeavors the best of both worlds: a drive for excellence and for staying abreast of advances in veterinary behavior medicine along with the common sense needed to make things work in the real world.

Even with such a busy professional life she makes the time to enjoy the finer things in life such as chocolate, coffee, the company of friends and horseback riding.   Her house is a home thanks to her rescue dogs, cat and horse.

Camilla Mauzy, PhD

Dr. Mauzy has been examining the uses of cutting-edge genetic approaches to the needs of the DoD, and is part of a new research focus at the Air Force Research Lab (AFRL) into Human Performance Optimization (HPO). This laboratory is currently examining several performance and cognition issues using state-of-the-art genetic and bioinformatic tools as aids to optimize training issues. One of the Air Force missions is the breeding and training of the Military Working Dog, and this project demonstrates a commitment and understanding that optimized training issues need to be addressed in the MWD as well as the soldier. Prior to joining AFRL/RHPB, Dr Mauzy was at VetGen LLC, Ann Arbor, MI, for over 71/2 years. During this period, she performed research on identification of gene mutations responsible for two inherited canine diseases: Juvenile Early Onset Cataract and Progressive Rod-cone Degeneration (PRCD). She also worked in screening select samples for mutations involved in the canine bleeding disorder von Willebrand's Disease (vWD). A committed dog lover, Dr. Mauzy hopes to bring the latest scientific technologies to advance Military Working Dog breeding and training issues.


Victor Chan, DPhil

Dr. Victor Chan received his Doctor of Philosophy degree from the University of Oxford, England.  Dr. Chan has been in charge of the Genomics Core Facility at the Applied Biotechnology Branch, Air Force Research Laboratory since 2001. During this period, Dr. Chan has been actively engaging in various research projects that use advanced genomics and proteomic profiling techniques. He also has been in charge of the development of advanced bioinformatics for data mining (pattern recognition, feature selection and classification), as well as for reverse engineering and modeling of biological networks.


Francis Galibert, PhD

Dr. Francis Galibert, 75, is an Emeritus Professor at the University of Rennes 1 (France). For many years he has been interested in genome structure comparison and has lead or participated in several sequencing projects; from the complete sequence of the Hepatitis B virus in the early days of the sequencing era to, more recently, that of the dog genome.

A molecular biologist by training, he became interested in dog genetics in the early 90s. At that time he realized the wealth of information held by the varied breeds, created to satisfy different purposes, which could be useful in deciphering the complexity of the haplotype / genotype relationship.  More recently he has turned his interest toward analyzing the very high olfactory capabilities that all dogs have with the hope of understanding why some breeds are more talented than others at particular tasks.
