Current Research
  • Modelling the dynamics of tree species response to various environmental perturbations, especially climate change
  • Evaluating intraspecific variation in tree species response to climate change 
  • Expanding the habitat suitability and migration potential models to encompass the entire conterminous US and across their entire range into Canada
  • Working with a team that consists of Landscape Ecologist, Wildlife Biologist and GIS Specialist, my main focus is on developing cutting edge modelling techniques to assist in tree species conservation and forest health maintenance that the American public demands. I love the challenge of constant innovation required to incorporate rapid developments in modelling/simulation and scientific computing fields.

Research Interest

I am interested in understanding tree species demographic response at a macroecological scale and using ensemble and simulation models to predict future suitable habitats and migration potential. My current interests are:
a) to understand within-species variation by evaluating genetic, ecological and environmental differences among populations under various disturbance regimes using multiple modelling techniques.
b) to expand our models that currently spans the eastern US ( to include the entire conterminous US and also into their entire range in Canada and Alaska

I love tinkering with models and scripts to come up with newer techniques and ideas to integrate the various components that constitute dynamic landscapes (ecology, genetics, biogeography etc) to improve management and conservation goals.

Why This Research Is Important

Forest health is being increasing affected by both natural and anthropogenic impacts resulting in changing and less robust forest landscapes. The forest managers need help in tackling contemporary issues like the impact of climate change, future seed zones, and assisted migration. My research uses a comprehensive approach which includes multi-stage statistical and simulation modelling, and the evaluation of intraspecific environmental and genetic population differences to address the challenge of forest health maintenance and tree species conservation in the United States and beyond.

Research Highlights

Collaboration with Canadian Researchers Key to Shared Stewardship of Iconic Tree Species

Year: 2020
Tree inventory data typically are confined to national boundaries and differ in formats and objectives, thus limiting their use for studying species wide ranges. Northern Research Station scientists collaborated with their colleagues in Canada to overcome this barrier to predict current and future h...

Mapping U.S. Drought Projections Helps Foresters Plan for Sustainability

Year: 2018
Droughts are natural disturbances that can cause negative effects on natural ecosystems and also have important social and economic consequences. Researchers are helping land managers prepare for changing climate conditions by developing projections of how drought may change in the future.

Improving prediction of future habitat distributions under climate change by combining multiple habitat suitability models

Year: 2017
Future habitat distributions are usually forecast using a single model with a single response, such as tree species abundance. Combining multiple models, integrating multiple responses, and looking for consensus and average predictions results in more reliable assessment of future habitat suitabilit...

Combining Genetics and Environmental Analysis to Assess Conservation Options for Eastern Hemlock

Year: 2016
Eastern hemlock is currently facing a dual threat by the invasive insect hemlock wooly adelgid and anthropogenic climate change. Combining genetic information with distribution models under climate change helps better understand options for the conservation of this imperiled species.
