2023

Grants and Awards — We are thrilled to share the exciting news of our FIRST NSF grant! We will develop mechanistic models for seasonal avian migration to understand if migrating animals can adjust their migration routes and schedules to track key resources even as the phenology of these resources shifts with climate change. This is a collaboration with Drs. Lam, Zhai and Loss. We will hire a two-years postdoc for this project! Come join us.

 

Lab attended Ecological Society of America annual meeting in Portland — We had a great time in ESA and we learnt a lot. Three graduate students presented their work and received very positive feedback!

 

Rabeca won first place at the Research Day at the Capitol — Lab undergraduate student, Rabeca, won first place in the research-intensive institution category at the Research Day at the Capitol event in Oklahoma City. It has been an amazing two years working with her and Ally (the graduate mentee) on the project of understanding efficacy of physical removal management on invasive grass under drought. Rabeca is currently working on two manuscripts that will be accomplished from this project. ​Go to this link for a nice write up.

 

New Lab Members

  • Lab is excited to welcome a new PhD student, Gabriel Hessler, who will start in the Fall 2023. Gabriel is interested in how the living things around us respond to environmental changes or stressors inflicted either directly or indirectly by humans and looking at how we can model some of these changes in a lab setting. Welcome!
  • Lab is excited to welcome our first post-baccalaureate student,  Carson D. Turner, who will join the lab for one year, starting in June 2023. Carson is supported by the NSF ON-RaMP post-baccalaureate program, which offers mentored research experiences for postbaccalaureate graduates in the biological sciences. Welcome!

Publication —

  • First author paper on "Effective and timely use of models to inform on-the-ground management of invasive plants" is accepted in Biological Invasions.

2022

New Lab Members

  • Lab welcomed another new MS student, Ashley Baragary, who received her BS in Marine Biology from Northwest Missouri State University. Ashley is interested in aquatic ecology and conservation. In the future, she plans to study aquatic ecosystems, modeling how they are affected by external factors such as climate change and human behavior, and helping develop effective conservation and management plans. Welcome Ashley!
  • Lab welcomed another new MS student, Jamaal Jacobs, who received his BS from University of South Carolina. Jamaal is  interested in conservation ecology and evolution. He wants to study how climate change and human development are impacting various populations. Additionally, he wants to study ways that the impacts on endangered species can be managed. Welcome Jamaal!
  • Undergraduate student, Rabeca, is selected as one of the four undergraduate students from OSU to present her research at Research Day at the Capitol in Spring! We are super excited about this opportunity!

2020

Presentation in the Mathematical Biosciences Institute (the Ohio State University), Workshop: Life on Planet Earth: Above and Below — I was invited to give a presentation recently in the MBI workshop, and I talked about my work on "Connectivity and Ecological Dynamics". The talk includes understanding on: 1. How movement alters carrying capacity in heterogeneous environments, and how consumer-resource model made better and more accurate prediction than the logistic equation; 2. How does directed movement alter coexistence in heterogeneous environments? There were very nice discussions after the talk. Talk link is here. Thanks again to all the organizers and to check other talks, click here.
