Christine Archer, President

Christine Archer is the Zebrafish Facility Manager at the University of Colorado Anschutz Medical Campus. She received a BSc in Biology from the University of Ottawa in 2007, and then attended Algonquin College to attend their veterinary technology program, becoming a Registered Veterinary Technician in 2009. Christine has been interested in aquatic animals from a young age, having been a hobbyist aquarist since the age of 10. She jumped at the chance to start working with aquatic animals in a laboratory context in 2012, after several years working with rodents in research. Christine helped to run the University of Ottawa’s aquatics facility, housing many fresh, brackish, and saltwater species. She worked most closely with the zebrafish facility, working to improve colony management and facility operations. Christine is an advocate for improving the health monitoring and management of zebrafish in research, having found herself in a unique role merging animal health and aquatics husbandry. She has previously lectured to veterinary technology students and lab animal technicians alike, and wants to help ensure that institutional animal care departments improve their knowledge base and expertise regarding their management and care of aquatic animals. Christine has previously served for several years on the Board of one of the largest credentialed veterinary technician associations in North America, and has been involved with updating federal animal use guidelines for zebrafish and reptiles in Canada.

Joshua Barber, President-Elect 2022-2023

A fish hobbyist for the last 24 years, Josh Barber has turned his lifelong obsession into a career working with aquatic species in animal research. He holds a Bachelor’s degree in general biology from Wheaton College and a Master’s degree in biotechnology from Columbia University. He has spent the last 11 years in the aquatic research field during which he assisted many new and existing laboratories get up to speed with the latest operating procedures in aquatic husbandry and facility management. He worked as an aquatic specialist at the National Institutes of Health through Charles River Laboratories. He then took a position developing transgenic zebrafish at HHMI Janelia Research Campus from 2011 to 2015, growing the facility from two racks and a single investigator to twenty racks and a dozen researchers. In 2015 he was hired by Columbia University, to oversee their zebrafish facilities along with several other fish and amphibian species with over forty researchers. During this time, he taught several webinars on aquatics, gave talks at National AALAS, and published in JAALAS, CAALAS and Nature's Lab Animal. He believes there is a lack of aquatics talks and panels at lab animal conventions and passionately advocates for more to help grow the community. His hobbies include improv comedy, and shore fishing.


Joan Hedge, Vice President

Joan Hedge is a Biologist with the US EPA in Research Triangle Park, North Carolina where she has worked for the past 29 years.  She received a BS in Animal Science in 1988 and a MS in Physiology in 1994, both from North Carolina State University in Raleigh, NC. She is currently a zebrafish colony manager and is lucky enough to also conduct toxicology research with zebrafish embryos/larvae.

Joan started working in rodent research which included both acute and developmental neurotoxicity with an emphasis on thyrotoxic endocrine disruptors using the rat model.  More recently, over the past 10 years or so,  her research interests have shifted to focus on zebrafish husbandry and colony maintenance, as well as developmental neurotoxicity in the zebrafish model system.  Joan has authored or coauthored over 30 peer reviewed publications, and also serves on an IACUC.

Joan has really enjoyed meeting colleagues through the ZHA and in zebrafish training classes over the years.  Additionally, she loves the educational seminars the ZHA presents and looks forward to helping set those up along with organizing social events during her term as Vice President.


Haley Engle, Treasurer

Haley Engle is the Aquatics Supervisor at the Northwestern University Center for Comparative Medicine. She received a B.S. in Biology from the University of Oregon, and was introduced to zebrafish as a student research assistant in the Westerfield lab there. At UofO, she gained essential experience and fell in love with the fish and the unique community of zebrafish investigators and husbandry experts. Over the past twelve years, she has participated in zebrafish research as member of the De Jong lab at the University of Chicago and the Tamplin lab at the University of Illinois at Chicago. She currently supervises fish husbandry and facility operations at Northwestern University’s Simpson-Querrey zebrafish facility. She is interested in working to improve zebrafish husbandry standards and expand knowledge of what constitutes an optimal living environment for research zebrafish. She believes that zebrafish have amazing potential as a model organism, and are a wonderful species with their own special kind of charisma. During her time outside the fish facility, she plays violin as part of the Northwestern Medical Orchestra and during non-pandemic years, she race bikes with the Chicago area Half Acre Cycling team. As a member of the ZHA executive board, she hopes to contribute to the development of essential resources for the zebrafish husbandry and research communities.

Joana Monteiro, Secretary

Joana Monteiro is the Fish Platform Manager at Champalimaud Foundation, in Lisbon, Portugal. She received her bachelor in Marine Biology from the University of Algarve, and her PhD in Biomedical Sciences from the University of Lisbon, with 1st class honours. Overall, she has over 13 years of experience working with zebrafish, including 8 years of zebrafish -based research at the Gulbenkian Science Institute and 3.5 years as a senior technician at the Champalimaud Foundation Fish Platform, where she consolidated practical expertise in operating centralized life support recirculating systems, zebrafish husbandry and welfare, and transgenics generation. Since 2019, as the Fish Platform Manager, she oversees a team of 6 dedicated technicians. She coordinates the aquaculture activities for 3 fish species and scientific services provided by the Platform staff. These include a colony management programme for more than 200 zebrafish strains, generation of transgenic and mutant lines, assisted reproduction techniques, optimization of husbandry protocols for different fish species. Joana has been an active scientist throughout her career, with published work on zebrafish husbandry, welfare, CRISPR/Cas gene editing, and regeneration. She is a member of the Animal Welfare Body (ORBEA) at Champalimaud Foundation, a teacher at courses on Laboratory Animal Science for more than 10 years, and an invited lecturer at several Masters degree courses.
