2022 - Tetra Tech, Inc. 

           Senior Wildlife Biologist

Responsible for multiple facets of the permitting and reporting process for clean energy projects. Responsibilities include preparation of bird and bat conservation strategies, post construction fatality modeling, evidence of absence and indirect take estimation and modeling, leading field teams and preparing field reports pertaining to species of conservation concern, wildlife surveys, sensitive plant surveys, GIS desktop analyses of known occurrences of T&E species, eagle fatality modeling, and post construction mitigation analysis. Each of these items has research, data preparation, scientific writing, client integration, and reporting aspects. Current workflow includes task-leading research teams across multiple projects, statistical analysis of field collected data within EoA, CRM, and GenEst environments, and establishing a program focused on increasing habitat for native pollinators throughout the Pacific Northwest.


2018 -  Hancock Forest Management/Hancock Natural Resource Group

2020    Wildlife Biologist


Responsible for the management of natural resources on roughly 600,000 acres of licensable hunting ground in Texas, Louisiana, and Oklahoma. Managed species included white-tailed deer (Odocoileus virginianus), Eastern wild turkey (Meleagris gallopavo silvestris), bobwhite quail (Colinus virginianus), multiple species of duck (Anas spp.) and sensitive plant and animal species including Texas trailing phlox (Phlox nivalis ssp. texensis), Texas screwstem (Bartonia texana), and the red-cockaded woodpecker (Leuconotopicus borealis). Established collaborations with state and federal wildlife agencies, regional universities, forestry associations, and botanical societies to ensure harvested populations are being properly monitored for the long-term health of each species. Created and implemented measures aimed at controlling populations of introduced feral hogs (Sus scrofa) to limit destruction to forestlands and native plant and animal species. Established or expanded programs and revenue streams related to apiary leases, wetland mitigation, and other value-added services. Exceeded recreational income goal by roughly 2 million dollars in the 2019-2020 fiscal period.

2012 -    Dr. Derek Johnson, Virginia Commonwealth University

2017      Ph.D. Candidate/Primary Investigator


Doctoral research focused on assessing the sustainability of snapping turtles (Chelydra serpentina) under current and increasing commercial harvest pressure within Virginia waterways.  Research included mark/recapture of both common snapping turtles and by-catch turtle species in three Virginia waterways representing a range of historic commercial harvest intensity. Telemetry data collected from 23 snapping turtles was used to infer movement patterns, habitat usage, conspecific interactions, and population density. Nail samples were taken from turtles collected to study mercury loads across size classes of snapping turtles and to examine ontogenetic shifts in feeding. This was a four-year project funded through the Virginia Department of Game and Inland Fisheries.


2008-    Dr. Mietek Kolipinski, Senior Scientist, National Park 

2009     Service, Pacific West Regional Office, San Francisco, CA

             Primary Investigator


Developed and executed research project cataloguing the bee and wasp species present in Marin County, California.  Research involved collecting and preserving bee, wasp and plant samples at 15 sites within Marin County, including sites at the Point Reyes National Seashore and Golden Gate National Recreation Areas.  Laboratory research included preserving specimens, species identification, working with local professional botanists and biologists, cataloguing data and management of 5 research assistants.

2008    Ecology and Conservation Field Study,

            Galapagos Islands, Ecuador

            Field Researcher


Research emphasis was on interaction amongst tortoise species native to the Galapagos Islands including variation in shell morphologies, home ranges, reproduction habits and human impact on life cycles. Duties included overseeing research groups, collecting and analyzing data, and working with residents and agencies.
