Dr. Tyler J Grant

Postdoctoral Research Associate

I am interested in applying quantitative methods to ecological and conservation problems.  Particular interests include agent-based modeling, occupancy estimation, Bayesian hierarchical modeling, mark-recapture analysis, and sampling designs.  Currently I am applying my skills to monarch butterfly conservation.  I have developed an agent-based model for Monarch Butterflies to assess the implications of the spatial arrangement of habitat patches on landscape-scale monarch butterfly reproduction.  

A demonstration of this model can be found in the video below:

Modeling monarch butterfly movement and egg-laying

In the future I plan to continue my research in academia, government, or the non-profit sector.  


In 2015 I completed my PhD in Wildlife Ecology in the Department of Natural Resource Ecology and Management at Iowa State University.  My research was on herpetological fauna as indicators for use in wetland restoration of the Missouri River floodplain.  From 2005 to 2009 I worked for the U.S. Fish and Wildlife Service (USFWS) in Carslbad, CA where I learned how the Endangered Species Act works on the ground.  I was involved in studies of monitoring flat-tailed horned lizards, coastal cactus wren, Coachella Valley fringe-toed lizards, Laguna Mountains skipper, and other species. Previous to working for USFWS, I completed my M.S. degree at Colorado State University on monitoring methods for flat-tailed horned lizards (mark-recapture, distance sampling, occupancy estimation) and manipulative experimentation to evaluate effects of off-highway vehicles.
