Descriptions and Phylogenetic Relationships of the Guiana Shield Pencil Catfishes
(2022-07-21)
The systematics of the catfish genus Trichomycterus Valenciennes 1832 are complicated and unresolved. This genus is paraphyletic, containing all members of the Trichomycterinae that cannot be adequately placed into an ...
The Involvement of Copper in Leigh Syndrome
(2022-07-29)
Leigh Syndrome is a neurodegenerative disease that presents with bilateral lesions in the brain. This condition is characterized by progressive loss of mental and movement abilities in which these symptoms start as early ...
Evolutionary Consequences of Gen(om)e Duplications in Animals
(2022-07-25)
My research interests can be broadly described as an attempt to explore the drivers of macroevolutionary processes and diversity patterns across taxa. One such driver is the contribution of gene and genome duplications. ...
Evolutionary Ecology of Loricariid Catfishes
(2022-07-25)
How extrinsic (like functional constrains and ecological interactions) and intrinsic (like modularity and integration) interactions drive diversification is a formative area of evolutionary biology. In this dissertation, ...
Developing omics and cell culture resources in non-model organism for their application in elucidating complex trait evolution in natural populations.
(2022-08-15)
In the past, researchers chose models organisms to answer research questions based on their simplicity in morphology, domestication, and/or life history traits. Now, with high throughput sequencing (HTS) rapidly becoming ...
Using squamate systems to understand molecular underpinnings of evolutionary processes
(2022-12-02)
The solidification of evolutionary biology as a scientific theory provided a foundation for understanding the source of life’s variation, an objective that has since become a central aim in biology. While scientific ...
Prevention of disease due to hypervirulent Aeromonas hydrophila (vAh) and a global survey of vAh in farmed fish
(2023-04-13)
This dissertation documents research focusing on hypervirulent Aeromonas hydrophila (vAh) regarding its geographical distribution, potential transmission among freshwater fish species, vaccine control, and probiotic control. ...
Characterizing the Chemical and Structural Basis of Animal Coloration from an Evolutionary Perspective
(2023-04-20)
Many questions regarding how animals produce their striking range of colors remain
unanswered, particularly when pigments and structures are combined. In this dissertation, I
completed four studies centered around ...
Characterizing and Changing Course Elements in Undergraduate Biology Education
(2023-04-17)
I conducted a set of four studies to catalogue and examine course elements, including active learning strategies and evidence-based teaching practices, and their influence on student experiences and performance in college ...
Using Preparation for Future Learning to Change Student Attitudes about Race in Undergraduate Genetics Laboratories
(2023-04-18)
Racist actions and views are complex, can be implicit or explicit, and are not necessarily
acknowledged or understood by the people who are contributing to racism in society. These
views and actions have broad impacts ...
