Welcome to our department!
I received Ph. D. in Microbiology from University of Southwestern Louisiana. Before that I obtained M. Sc. in Microbiology from Maharaja Sayajirao University at Baroda (India), a Diploma in Pharmacy from the Bombay College of Pharmacy and B. Sc. - major: Microbiology and minor: Chemistry - with Honors from Bombay University, Bombay (India).
I have worked as a research fellow, at the Cancer Research Institute (Chemotherapy Division), Bombay(India). After graduating from the University of SW Louisiana, I carried out postdoctoral research at the Michigan Cancer Foundation (Chemistry Department); and at the University of Michigan (The Simpson Memorial Institute, Division of Hematology). After graduating with a Ph. D. degree, I have studied the mechanism of ribosomal peptidyltransferase and recombinant DNA techniques.
At Eastern Washington University, I am involved in teaching undergraduate and graduate students through formal lecture classes, research projects and by directed studies. My students are also my co-authors in research presentations and publications.

As an Associate Professor at Eastern Washington University, I conduct research on riparian and plant ecology and teach Ecology, Botany, Research Design and Literature, and Riparian Ecology.
I am actively seeking graduate students who are interested in pursuing a master's degree in plant or riparian ecology. Please contact me if you are interested.

The focus of my research lab is on the neurochemical messenger dopamine and its role in brain function. Specifically, my research has explored how drugs (e.g., amphetamine and methamphetamine) impact dopamine mediated behaviors and cellular signaling molecules implicated in memory formation. More recent research elucidated amphetamine's cellular mechanism of action on dopamine neurotransmission. As a faculty member at EWU, my lab utilizes the technique of voltammetry which provides one the ability to monitor the activity of specific molecules (e.g., dopamine) in the brain. Future directions are to continue to investigate dopamine function, how drugs impact these processes, and dopamine dysfunction related to pathological conditions such as Parkinson's disease.

My research interests are in comparative physiology, with the overall goal of understanding how the ecology and evolution of species are shaped by cellular-level processes. Information about current and future research projects is provided on my webpage (http://access.ewu.edu/Joanna-Joyner-Matos).
I am actively recruiting undergraduate and graduate students to participate in on-going research and design independent projects. Please contact me if you are interested in participating in lab-based or field research.

My research interests are in the evolutionary genetics of host/pathogen interactions. I am particularly interested in understanding how pathogen genetics and virulence change following host shifts to permit a successful long term infection of the novel host.
Students interested in undergraduate or graduate research experiences should contact me by email to set up an appointment to meet and discuss current opportunities in the lab.
Currently I am collaborating with researchers from the University of California, University of Minnesota, and Simon Frasier University on projects linking stream community and ecosystem processes to the landscape of a northern California watershed. Projects include 1) measuring nutrient regeneration by dominant invertebrates, 2) determining landscape controls on stream primary productivity and terrestrial carbon inputs, 3) using stable isotopes and diet analysis to compare how energy moves through food webs in productive and unproductive streams.
I have also become interested in using measurements of basic ecosystem processes, such as primary productivity and nutrient cycling, as tools to evaluate stream ecosystem health. Anthropogenic impacts to streams are often assessed through labor-intensive biological monitoring based on invertebrate or algal communities. Measurements of ecosystem processes may be cheaper and less labor-intensive, and provide more insight into functional changes that may have occurred. However, their application to biological assessment has not been well-tested. I have begun some preliminary work comparing measures of nutrient uptake to conventional biological assessment using invertebrates, which I hope to expand

I am deeply curious about patterns and processes that shape organismal diversity. I am interested in the evolution of morphological diversity in plants (e.g., plant architecture), historical biogeography and aspects of evolutionary ecology, such as habitat preferences, pollinator-mediated hybridization and introgression. My approaches have included developmental and comparative morphology, molecular systematics, population genetics and field pollination biology. My primary study system has been the small tribe Montieae (Portulacaceae), but additional systems have included Loasaceae and more recently Asclepias (Apocynaceae). With my research, I aim to synthesize evidence in a phylogenetic framework from diverse fields to understand plant species diversity.
Research opportunities for students are the central focus of my research agenda. I frame many of my research questions in "bite-sized" chunks, so that they are attractive and doable to students who may have limited time, but substantial interest. This approach produces project ideas that are perfect for student research because they can be accomplished as individualized units, but effectively contribute to my broader research objectives. However, providing projects from my own research are not the sole aim of my research agenda. I am equally motivated to mentor student-initiated independent projects. Students with an interest in plant systematics, population biology, biogeography or morphology are encouraged to contact me.
