I am interested in applied insect ecology, evolution, insect behavior, transmission of plant diseases by insect vectors, and integrated pest management. Modern agriculture is an important factor contributing to the global environmental change. Although proper nutrition is essential for maintaining human and animal health, many practices characteristic of industrialized farming are either currently, or potentially hazardous. These include, but limited to, using high levels of non-renewable fossil-derived inputs, oversimplification of ecosystems due to extensive monocultures, greenhouse gas emissions, and runoff of nutrients and toxins to ground and surface bodies of water. Furthermore, high densities of cultivated plants and domestic animals within production and storage areas is very conducive to creating outbreaks of pathogenic organisms, including those attacking humans. Therefore, creating and maintaining healthy environments is not possible without optimizing management of agricultural systems. In particular, contagious diseases caused by a variety of pathogens have important ecological, economic, and environmental impacts. These can act directly on the infected hosts, as well as indirectly by affecting the availability and distribution of available resources. Because of its great practical importance, a considerable research effort has been dedicated to understanding epidemiology of animal and plant diseases. However, despite general principles being similar across different systems, communication among scientists working with animals and plants is often insufficient. Furthermore, relatively little attention is being paid to community-level effects of disease across taxa and trophic levels. Taking a more integrated approach is likely to create considerable synergy in the investigation of disease epidemiology, and the effects of contagious disease on natural environments and human society.

I approach marine mammal science with a broad focus on ocean health that incorporates interconnected components of animal, human, and ecosystem health. My research program utilizes genetic and genomic techniques to study evolutionary adaptation, population ecology, and conservation biology. I am driven by questions of how individuals have adapted to survive threats in their environment over evolutionary and ecological timescales, and how genetic variation (or lack thereof) affects resistance to these threats in the face of rapid environmental change. My research focuses primarily on marine mammals that are sentinels of ocean health and species of conservation concern. In collaboration with several members of the North Atlantic Seal Research Consortium, I am currently investigating the implications of historical exploitation, human-natural conflict following recent population expansion, and disease susceptibility in local populations of gray and harbor seals.

I am an applied social scientist that has worked in the areas of sustainable rural livelihoods, health and wellbeing, collaborative management of natural resources, and adaptation to global changes. Given the interdisciplinary nature of my work, the “One Health” approach has been integral to my research in the US and abroad. I use an array of qualitative and quantitative methodologies in my research, while focusing on the development of participatory models that ensure stakeholder engagement to enhance the resilience of human-natural systems.

I am an entomologist with an interest in the ecology of infectious diseases of humans, wildlife, and domesticated animals that are transmitted by arthropod vectors. Because transmission of vector-borne diseases depends upon the complex interactions between an arthropod vector, the pathogen, and a vertebrate amplifying host, this research area benefits from a One Health approach and draws upon theory and methods from ecology, conservation biology, and epidemiology. I use lab and field studies in conjunction with geographic, quantitative, and molecular tools to address questions related to 1) the effects of landscape and environmental change on vector-borne disease dynamics, 2) predicting the distribution and movement of vector-borne pathogens in space and time, and 3) mitigation strategies to reduce the burden of vector-borne disease. My current focal study systems include mosquito-borne diseases such as West Nile virus and Zika virus and tick-borne diseases such as Lyme disease.

Increasing levels of greenhouse gas emissions and anthropogenic chemicals have led to rapid and significant shifts in abiotic environmental factors. In this context, our research explores two broad questions utilizing various teleost fish species: (i) How do organisms respond to changes in their natural environment? (ii) Can wild fish populations serve as indicators of environmental health?

My research applies genetic/genomic and statistical approaches to better understand infectious disease transmission dynamics and host-pathogen adaptation in wildlife disease systems, particularly those involving an interface with livestock and humans. This work is necessarily grounded in an interdisciplinary “One Health” framework that considers both domestic and wild animal health in the context of the ecosystem and the connection to human activities. It also involves both field and laboratory components, and multidisciplinary analyses that integrate genetic information with ecological, immunological, and epidemiological data. Current disease systems include brucellosis in wildlife and livestock of the Greater Yellowstone Ecosystem, pneumonia in wild and domestic sheep and goats, anthrax in plains zebra of southern Africa, and pathogens in migrating and resident birds along the Palearctic-African Flyway.  My other research interests include the investigation of population trends, structure, connectivity, hybridization, and evolutionary adaptation in threatened and invasive species.

My research interests focus on the intersection of human (social systems) and natural resources (ecological systems), thus my work is interdisciplinary in nature. At this intersection, I examine the social impacts of resource management – the community interactions, associated conflicts, and decision-making. This research is called, human dimensions of natural resources and I focus on wildlife and fisheries management issues. I am interested in understanding future management directives/objectives, current management strengths/weaknesses, and public opinion towards difference species and management actions.
