Michael Blum, Ph.D. 

Director, Tulane-Xavier Center for Bioenvironmental Research

Associate Professor, Department of Ecology and Evolutionary Biology

Eugenie Schwartz Professor of River and Coastal Studies


Dr. Blum’s early work examines how landscape changes debilitize hybrid zones and how unstable hybrid zones relate to models of evolutionary diversification, focusing on the Neotropical butterflies that serve as model systems for the study of hybridization, speciation, and adaptive radiations. Dr. Blum's current research applies his understanding of hybridization and adaptive evolution to the study of land use, invasive species, and the impact of climate change on aquatic ecosystems. Although he has been involved in research that encompasses a range of freshwater and estuarine biota, he is now pursuing studies of freshwater fishes and coastal marsh plants.


Amy Lesen, Ph. D 

Research Associate Professor, Tulane-Xavier Center for Bioenvironmental Research 

Dr. Lesen's work focuses on the relationship between ecological processes and human social dynamics in coastal cities and coastal communities and how those systems are influenced by climate and environmental change; her current projects are primarily situated in New Orleans and Southeastern Louisiana. Dr. Lesen's research program spans multiple academic disciplines including the sociological aspects of biophysical science practice, scientific public engagement, science communication, participatory research, and interdisciplinarity. Dr. Lesen's past research addresses marine fisheries biology and management, as well as marine microbial ecology and food web dynamics focusing on both benthic and planktonic marine protists.

Shelley J. Meaux

Department Administrator, Tulane-Xavier Center for Bioenvironmental Research 

Shelley Meaux is responsible for the day-to-day operation of the Center and provides administrative and programmatic support for all of CBR’s initiatives. Meaux's interest in environmental issues began when she was an undergraduate at Tulane, where she co-authored the university’s first greenhouse gas emissions inventory. Meaux continues her work today as the department administrator of CBR by helping to develop Tulane’s climate action plan and greenhouse gas emissions inventory for the American College and University Presidents Climate Commitment.


Rosalyn Rael 

Postdoctoral Researcher, Tulane-Xavier Center for Bioenvironmental Research

Research interests: evolution of ecosystem structure and the impacts of the confluence of humans and natural ecosystems on patterns of  species abundance and diversity


A mathematical biologist, Rosalyn Rael's previous research focused on the dynamics and evolution of competition and predator-prey relationships using networks, differential and difference equations, stochastic models, and evolutionary game theory. Rael's current work involves modeling the dynamics of a pathogen reservoir host species to assess changes in the distribution of human exposure risk through time, as well as the societal and ecological impacts of intervention and control strategies.


Kristine Moody

Postdoctoral Research Fellow, Tulane-Xavier Center for Bioenvironmental Research

Kristine Moody is an integrative evolutionary geneticist who uses a multitude of tools to answer fundamental evolutionary questions of local adaptation and population connectivity to inform conservation strategies.

Moody's past work focused on the stream fishes endemic to the Hawaiian Islands with the integration of modeling, genomics and phenotypic experiments. Currently, her work aims to combine ecological modeling and genomics to understand how invasive species affect the health, population structure and ecology of native stream fauna on O'ahu.

Joshua Lewis 

Research Analyst, Tulane-Xavier Center for Bioenvironmental Research

 A CBR affiliated researcher since 2008, Josh has participated in a variety of community-engaged research initiatives around urban        ecosystems, particularly in the Bayou Bienvenue Drainage Basin along New Orleans’s eastern margin. Currently, Lewis coordinates a collaborative research project between the CBR and the Stockholm Resilience Centre entitled “Socioecological Movements in Urban Ecosystems,” bringing together historical ecology, urban forestry, and ethnographic social science methodologies to understand transformations in the urban landscape. More information on this project can be found at situatedecologies.net.

Ama Rogan 

Managing Director, A Studio in the Woods

Ama Rogan is a New Orleans native and painter with a BFA from the Rhode Island School of Design. Rogan's versatile background in non-profit administration and peer counseling credit her with excellent managerial and people skills. Ama Rogan's past experience includes serving as program committee chair on the Founding Board of Directors, a committee responsible for the design and execution of all residency programming for ASITW. In June 2003, Rogan was hired as assistant director; she was promoted to her current position as managing director in January 2014. Rogan oversees the development and management of arts and environmental residencies, as well as events, programs, proposal writing, community outreach and budget preparation. Ama Rogan communicates with Tulane faculty, staff and administrators, as well as the Board of Directors of Friends of A Studio in the Woods and their funding agency representatives.

David Baker 

Environmental Curator, A Studio in the Woods

David Baker has spent 20 years studying the impacts of hurricanes on Louisiana's Bottomland Hardwood Forest, focusing on forest recovery and invasive species management. At A Studio In The Woods, Baker's work has been focused on the eradication of Chinese privet and Chinese tallow, as well as establishing research plots which encompass 600 trees within the Bottomland Hardwood Forest.


Cammie Hill-Prewitt 

Residency Coordinator, A Studio in the Woods

Before moving to New Orleans to pursue a master's degree in art history at Tulane, Cammie Hill-Prewitt was the program manager of a non-profit organization in San Francisco working with emerging visual artists. Passionate about the arts, Hill-Prewitt has worked in non-profits for over ten years. Hill-Prewitt began her position at A Studio in the Woods in 2007 and enjoys finding new ways to bring the arts to the Greater New Orleans community and to students of all ages. Cammie helps to source the materials, sites and individuals for A Studio In The Woods to create risk-taking new pieces during their residencies, often looking to Tulane students and community volunteers to help produce the artists' work. In addition to facilitating programmatic activities such as the Kids in the Woods summer camp and the annual FORESTival fundraiser, she acts as a grantwriter, bookkeeper, and database manager for the organization.
