Miriam Handler

I am a MS student in the Environmental Science Graduate Program. Currently, I study how variable atmospheric conditions influence species migration by simulating an ocean, land, and atmosphere model (OLAM).  Specifically, under the speculation that birds are navigated by their olfactory system, I am modeling how smells are released in the atmosphere, while linking this to physical samples of air meant to represent volatile organic carbon (VOC) concentrations in the areas of interest.

Ashley Matheny

I am a PhD candidate with extensive technical background in eco-hydrologic research, land-surface and numerical modeling, and civil engineering. My research focuses on understanding and modeling transpiration from forested ecosystems. Transpiration from terrestrial ecosystems forms the critical link between the carbon and water cycles, but is not currently well represented by land-surface models.

At the University of Michigan Biological Station, I conduct sap flow measurements in disturbed and undisturbed forest areas; I use these experimental results and eddy covariance measurements to conduct tree level hydrodynamic simulations of water flux. Using remote sensing data, we can scale these tree scale simulations to the plot level. Eventually, this type of tree hydrodynamic model will be incorporated into land-surface models to reduce error in simulated water and carbon fluxes.

Golnaz Mirfenderesgi

 

I am an environmental engineering PhD candidate in the department of Civil, Environmental and Geodetic Engineering with a background in meta-modeling and evolutionary optimization for water resources management, data assimilation and remote sensing. My current research mainly focuses on the eco-hydrology, numerical and land surface modeling.

I have developed the finite difference ecosystem-scale tree crown hydrodynamics model version 2 (FETCH2). FETCH2 is a tree-scale hydrodynamic model of transpiration which resolves the fast dynamics of stomatal conductance at the tree level through a multi-layer canopy. While highly simplified, this approach brings additional realism to the simulation of transpiration by linking stomatal responses to stem water potential rather than directly to soil moisture, as is currently the case in the majority of land surface models.

Timothy Morin

I am a Graduate Research Associate in the Ecohydrometeorology group. I study how greenhouse gases are formed and absorbed in wetlands. Wetland plants uptake a great deal of carbon dioxide through photosynthesis. However, because of standing water, the carbon in the soil is not exposed to oxygen and some of it breaks down into methane gas over time.

We have measured how both of these gases are exchanged in wetlands for five years now and are now integrating our unique data sets to improve global modeling efforts to better represent the climate interactions of wetlands.

Austin Rechner

 

I am an undergraduate student in the Environmental Engineering program. I study how greenhouse gases are absorbed and released within wetland systems. I also assist in the collection of data for the study of how these gases are released from the soil systems through various plants.

 

 

 

 

Andres Camilo Rey Sanchez

 

I am a PhD student in the Environmental Science Graduate Program. I am a forest engineer from Colombia, interested in studying gas exchange between the atmosphere and the biosphere. In particular, I study the effects of climate change on carbon cycling.

Chante' Vines

 

I am a Civil Engineering Ph.D. student in the Civil, Environmental, and Geodectic Engineering
department. I study land cover contributions to methane emissions in a heterogeneous area. I
use flux footprint analysis and eddy covariance measurements to approximate methane
contribution from the Old Woman Creek wetland patch types. I am also working on
developing a footprint model using the Parallelized Large Eddy Simulation Model for
Atmospheric and Oceanic Flows (PALM).
